2019 GMC Acadia Problems & Complaints

My 2019 GMC Acadia suffered a "major trans fluid leak" specifically from the transmission accumulator feed pipe. Because of this leak, the transmission lost its necessary hydraulic pressure, leading to "internal damage". This is why I experienced harsh shifts and a complete "missing 3rd gear". This exact part and failure mode are the center of NHTSA Recall 20V668. The recall warns that missing bolts on the accumulator can cause a fluid leak, progressing to a total loss of propulsion—which is exactly what has happened to my vehicle.

2109 Acadia. The gear shift would not register as being in park when it actually was in park. This created an issue of the interior lights and radio not being turned off when the driver door was opened, posing the possibility of the battery being drained and the driver stranded. Upon searching, it was learned many Acadias have had this issue, including a friends'. This was reported to GMC Executive Resolution Team and that it cost us $341.38 to get it repaired. They refused reimbursement and have not issued a recall even though many Acadias are involved in this problem.

The contact owns a 2019 GMC Acadia. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed. The contact restarted the vehicle and was able to successfully park and turn off the vehicle after several attempts. Additionally, while driving at various speeds, the vehicle intermittently failed to shift as intended. Additionally, the A/C system was inoperable while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was determined that the cooler and thermostat needed to be replaced. The parts were replaced; however, the vehicle was not serviced for the transmission failures. The contact stated that the vehicle was difficult to start, and the doors failed to close intermittently. The vehicle was taken to the dealer, where the battery was replaced. The contact stated that the transmission failure persisted, and there was an abnormal odor coming from underneath the hood. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was unknown.

Ongoing problem with only solution is a recall notice. Power Steering Assist Reduced -Customer reports Power Steering Assist Reduced message displayed on DIC, A/C is inoperative, Engine Coolant Temperature Sensor inoperative. Recall needed to update Engine Control Module (ECM) with latest calibration.

The warning steering assist reduced, drive with caution appears. Shift to park appears. Temperature gauge drops to zero. Fan runs on high. A/C & heater don’t not work when this happens. We certainly do not feel safe driving our Acadia like this. Can’t trust that it won’t start on fire.

When shiftiing to park and turning the car off the message "Action Required Shift to Park". It is difficult to get the message to go away.

Park to shift issue - the vehicle did not register that I was in park, jerked hard when trying to place in gear, did not register the PROPER gear (reverse, neutral, drive), would NOT unlock doors to let passengers out even if it were an emergency. Seems to be triggered on inclines but have also been having issues on flat ground. Other Acadia's apparently have a recall for this issue but my VIN does not register as recalled which is not acceptable. https://www.quillarrowlaw.com/blog/gmc-acadia-shift-to-park-recall-what-owners-need-to-know/ THEN trying to accelerate on road it acted as though in neutral, would only barely function in low gear. Again, gear shifting did not respond. The fab did not register to unlock the car (it has a new battery) or the trunk, or start the car just prior to the issue revealing itself.

My 2019 GMC SLT seems to be having sensor problems. I keep getting a message that my driver assist is reduced and my A/C only blows out hot air. It’s done this to me randomly id say about 4-5 times. It will go off as I’m driving and than my temp gauge goes to zero. I did research and alot of other users have the same issue and say thermostat or thermostat sensor. If I disconnect my negative on battery and wait a few minutes it will work again.

2019 GMC Acadia message: Action Required Steering Assist Is Reduced Drive with care Both power steering and AC affected, check engine light on, engine temperature gauge off

The "shift to park" continues to pop up and can take as long as 20 minutes to get it to go off. From what I have seen this is a super common issues for the 2019 models and why there isn't an active recall I am not sure. Getting pretty frustrating when I have read 100s of complaints about the same thing and GM isn't doing anything about it.

I see where GMC Acadia is have a recall on transmission and if it’s the description of my two GMC Acadia’s, but when I put my Vin number in it doesn’t have a recall

It has the ABS lights on and tire traction light on check engine light on and given signs of failed transmission Slow to takeoff shuttering of transmission

Loss of steering assist code P0128 due to stuck thermostat.

In November 2022, I started getting a dashboard "shift to park" on my 2019 Acadia after I had parked and shut the vehicle off. At the time I took it into service to have it looked at/repaired, they told me there would probably be a recall on this issue,as it seemed to be a frequent problem, and I would get a refund for the repair. That recall never happened, and now my car is once again displaying the same issue. The dealership will not cover the repair, and I will be responsible, as it is out of their 2 year warranty window. I can't just ignore this issue and keep driving, as with the "shift to park" display, there is a constant alarm that doesn't stop unless the park switch recognizes the car is in park, even when it is shut off. I feel this issue needs to be placed under a recall, and I should not have to pay AGAIN for it to be repaired.

My Acadia keeps an error message of "Shift to Park" this has been happening on and off for about 8 months. Now it goes on every time I try to shut my car off. I have to stop and start it up to 20 times before it shuts off. I am concerned that I may be somewhere and won't be able to turn it off. I know there have been recalls for this and I need this repaired. It's obviously a flaw on GMC and honestly, I should not have to pay for it. At this point, the car is only used close by my home. I don't feel safe using it. Please help. Not only me but all drivers affected. Thank you

Error shift to park it come and go all the time. You cannot lock your car when this happens. Cost 500.00 to repair.. common problem for r This year.

Shift to park error on dashboard When turning the car off and it is in park, the car does not register that it is in park and continues to run electronics in the car. Causing the car to show the error on the dashboard. This runs the battery down and car may jump out of park and roll. Asked dealer to look at it and they refused due to it not being on the recall list for my vin #. No, dealer refused and no other person will touch this issue, since its electronic in the vehicle and only the dealer can fix. Had it to another repair shop that informed me of this information. No known abnormalities prior to the incident that occurs every time you try to shut off the vehicle. Causing several attempts to turn the car off and make sure it is off and does not move on its own.

The engine temperature gauge was reading cold when driving for 40 minutes and the fan was running on high. Also said steering assist reduced. Brought it in and had to replace the thermostat, because of the code they received. That fixed the issue.

Owner of a 2019 GMC Acadia Denali (VIN: [XXX] , current odometer ~87,164 miles), purchased new. In early February 2026, the check engine light came on. Independent diagnostic scan confirmed persistent P0420 code (“Catalyst System Efficiency Below Threshold Bank 1”) as current, history, pending, and permanent. Inspection showed the front exhaust pipe bracket had snapped, damaging the flex pipe and causing an exhaust leak. This failure mode directly triggers the P0420 code and requires replacement of the bracket and affected flex pipe section. This is a known recurring issue on GM’s Lambda-platform vehicles (shared platform, 3.6L V6 engine, and exhaust system design). GM Special Coverage Adjustment N212356540 covers 2019 Chevrolet Traverse and Buick Enclave models for front exhaust pipe bracket separation (resulting in pipe damage, holes, leaks, rattling, or efficiency codes), providing free repair for 15 years or 150,000 miles from in-service date, regardless of ownership. The failure on this Acadia is mechanically identical, yet the model is excluded from coverage despite matching part design and numerous similar owner complaints documented on NHTSA and BBB reports. Multiple attempts were made to resolve through the selling dealership (no response to service inquiries). Matter was escalated to GM Executive Resolution. GM required a redundant diagnostic scan at an authorized dealer (additional cost incurred), despite independent confirmation of the issue. GM ultimately denied any coverage, TSB applicability, goodwill assistance, or further support. The snapped bracket and resulting exhaust leak can produce noise, fumes in cabin, potential component damage, and emissions noncompliance via false/legitimate catalyst efficiency codes. Inconsistent application of coverage for the identical defect across equivalent Lambda-platform models raises concerns about a widespread safety/emissions issue affecting 2019 GMC Acadia.

My car will be in park and it always says shift to park when its in park , this is very unsafe. Also when I change gears from park to drive or reverse the RPM revs up gets stuck then drops quick causing the hesitation and then kicks in.

My 2019 Acadia often will not turn off because it has a Shift to Park issue. Apparently it is caused by a faulty microswitch in the shifter assembly that fails to signal the Body Control Module when in park, leading to a persistent warning message, inability to turn off the vehicle and battery drain. It has been going on for at least 4 years. It appears there is a recall for this problem but when I search my VIN number a recall does not come up. There are many posts that say "certain" models in years 2017-2019 but why not mine? It is definitely a safety issue because it does not turn off.

The contact owns a 2019 GMC Acadia. The contact stated that while attempting to park the vehicle, the gear shifter failed to shift into park(P). The vehicle failed to turn off, with the message "Shift to Park" displayed with an audible chime. The contact was forced to move the gear shifter back and forth before it was recognized that the transmission was in park(P). A dealer was notified of the failure and the contact was provided an estimate for the repair. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 69,000.

Parts # 84733196 Harness ASM-TRAS CONT WRG and 84955379 SWITCH ASM-TRNS CONT have been replaced three times. This is described by dealer as a faulty PARK SWITCH. When this switch fails the vehicle is unable to be shifted to park. Vehicle needed to be located in a level position, wheels chocked and battery disconnected to safely disable the vehicle. Dealership and General Motors has been made aware of problem won't do anything, other that have me pay for the labor and new part to fix it, AGAIN. There is no warning ,it simple decides to fail to shift to park.

Vehicle experiences multiple simultaneous failures including “Steering Assist Reduced / Drive With Care” warning, extremely loud cooling fan operation, temperature gauge not functioning, tire pressure monitoring system failure, and widespread electrical issues (windows, mirrors, infotainment delay). Issues occurred together and are consistent with numerous owner reports for 2019 GMC Acadia models. Condition affects steering assist and engine temperature monitoring, creating a potential safety risk.

My 2019 GMC Acadia has shift to park warning light that repeatedly keeps coming on I've tried to park it have to turn it off two to three times maybe four times I have paperwork that I have went to the dealer and they have fixed it twice with a harness that is failing it only is a temporary band-aid fix. Even though in Indiana we do not have a recall as I know of for this year I would need to have this fixed for my safety I fear that one time it may not go into park and I may not be able to shut my car off.

Shift to park alert continues to come on when car is already shifted into park. Car will not shut off without pulling car back out of park and shifting back into park. Causing a delay in all electrical attached to power down, potentially draining the battery.

The contact owns a 2019 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle stalled unexpectedly. There was no warning light illuminated. The vehicle was able to be restarted. The contact also stated that while coming to a stop and attempting to depress the brake pedal, the vehicle lost motive power but unexpectedly lunged forward. There was no warning light illuminated. The vehicle was restarted after the failure. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 85,695.

Started getting a warning indication when starting the vehicle that stated some portion of driver assist was not functioning (or some verbiage close to that). We didn't notice any difference in the operation of the vehicle and took it to a service shop after about a week. They did some testing and discovered the problem. I am not mechanical at all but they said there were several technical bulletins from the manufacturer that led them to the problem - a bent pin on one of the rocker arms. I am going to upload the technical bulletins (3) they provided me as well as the invoice (3 pages).

My park to shift to park warning keeps coming on. It was replaced under warranty once and came on again comes and goes and dealership is not replace it again saying it isn’t tripping a code so it won’t get covered under the parts warranty.

The contact owns a 2019 GMC Acadia. The contact stated that the vehicle failed to shift to park(P) as intended and could not be turned off. The message "Shift to Park" was displayed. The contact was able to turn off the vehicle after shifting to low gear. The local dealer was contacted and confirmed that the VIN was not included in a recall. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 60,000.

When I placed the vehicle in park, the dashboard alert/warning would signal "shift to park". This would continue to go off for quite some time, and it continued to get worse and take longer to shut off. Eventually the alarm would not go off I turned the car back on and off, nor if I engaged with the shifter. I could not leave my vehicle in this state, and I was unable to determine if my vehicle was truly in park, which is a huge safety concern to myself and others. This also caused the battery to drain, and could impair being able to start and run the vehicle. This problem has occured on many GMC vehicles, and there have been recalls issued for the other cars. I would like a recall issued for my VIN as well. I spent $800 fixing this issue and GMC will not cover the cost, even though this is a known problem with other Acadia's (even 2019).

Shift to park caused by a faulty micro switch. Woukd take up to 30 min to get car in park, leading to engine shutdown failures and possibly battery drain I did replace battery before I knew this was causing this. Messages did appear saying this was an issue ,must shift to park but no indication of how to do it. I got this repaired at barkley GMC Dec 29:30

My Temp control sensor is causing my check engine light to come on. After reviewing the problem, It seems many owners have had this same problem nation wide. I,m simply adding to the complaints by other owners that this should be a recall problem since so many owners are having this same problem. I,ve only had this car for 2 weeks & like the vehicle very much but this is a per the mechanic that may be caused by the sensor being placed too close to the exhaust without better protection from the heat. Please take this into consideration & hopefully come up with an adequate protective cover

Won't shift into park alert came on. Vehicle wouldn't shift into park. Danger of vehicle roll off? Took to GM dealer who replaced GM part 13545094 transmission controller aka shifter assembly. It is believed this defect was detected and recalled on 2018 GMC Acadia models. My 2019 was made in 2018. In service date 10/04/18.

Shift to Park Issue - this is a know issue/recall for the 2019 GMC acadia yet it when I enter my VIN number the recall doesn't show up as a problem. YET it took me 10 tries yesterday to try and turn my car off because each time I went to turn it off, I got the message to Shift it to Park. This has been occurring weekly since I purchased the used car in August 2025.

There are 2 issues im experiencing. The first is the vehicle won't allow me to shut down the engine because it doesnt recognize that its been shifted into "park". Ive already paid close to 800.00 to.have this repaired because my model year is not covered in the recall. Today, it started doing it again. The safety issue is that either I, my wife, or my teenage daughter (depending on who is with the vehicle). Can be left stranded, unless we pop the hood and disconnect the battery. The second issue is that the tire pressure monitor is no longer working. It is sending warnings that our tire pressure is low. When its not. The safety issue is needing to pull to the side of the road to check the tire pressure and also not knowing when the vehicle may actually have a low tire.

The transmission is shuttering and jerking, had it diagnosed and was told that the torque converter is going out with only 137,000 miles on my 2019 GMC Acadia

There is a "shift to park" alert that is listed as a recall from 2017-2019 gmc Acadia's. I have this alarm but apparently my vin is not affected. I would like this to be investigated as it seems my vehicle should be included in the recall.

Vehicle is in park, and the shft sensor does not recognize the shifter is in park. Won't let you turn off rhe car.

Shift to park error message when in park.

Check Engine Light came on with message of "Steering Assist is Reduced Drive with Care". This same thing happened to my sister-in-laws 2019 Acadia 2 months earlier. Took it in right away to the dealership to find out it's the thermostat, it's a common/known issue and it isn't covered under my extended warranty and will cost ~$1300. I'm seeing this is a common issue for Acadia's and has not had a recall, don't understand why. It's one thing if this is a easy part to replace, but GM has made it so that most people now need a dealership or auto repair shop to fix it.

Thermostat stuck open and a steering assist light came on engine temp needle at zero. Check engine light came on, Had to have thermostat and coolant engine temp sensor replaced

I'm going to have to replace my thermostat and most likely my sensor. It will pop up saying (steering assist is reduced drive with care) my temperature gage on my dash will sometimes will not go up, my heat is acting funny. I've had also when I put it in park saying it's not actually shifted into park.

The steering assist message comes on and off whenever the weather gets cold in the fall and winter. This causes my air conditioning and/or heater to not work. I have done research and the temperature sensor needs to get replaced because there is a malfunction of the temperature not reading the coolant. Everything is fine with fluids and driving. This happened when I turned on the heater.

Thermostat fails. Steering assist reduced message comes up on dash. Temperature gauge stops working, air conditioning stops working and engine fans run constantly when vehicle is running. I had the dealership fix and replace under warranty the first time and now it happened again a second time.

Shift to Park message comes up and vehicle will not turn off. This happens frequently and so far I have been able to get it to shift into park by clicking the lever on the shifter multiple times.

When in park the car is alerting to “shift to park”.

I bought a car about 2 months ago and they did not tell me the thermostat was bad and they won’t cover it.

Thermostat is repeatedly going bad. Throws Steering Assist reduced. Had it replaced twice and it’s bad again.

SHIFT INTO PARK ALERT AFTER CAR IS IN PARK

The Shift to Park is not recognizing when my car is in park and continues to ding and won’t let me turn my car off.

When parking the vehicle the electrical system will put a warning on the dash indicating you are not in park. A message indicates shift to park. The car will not shut off and you cannot lock the vehicle. This happened when I first bought the vehicle and it was under warranty and repaired. It is now happening a second time in 2025.

I purchased a used 2019 GMC Acadia from Grieco Honda around November 20, 2023. They showed me a CarFax report indicating the vehicle had never been in an accident. Immediately after the purchase, I reported several issues and attempted to return the car under their 30-day warranty. However, the salesperson convinced me not to return it, assuring me that they would address all of the problems. From the beginning, I complained that the car shook violently when driving between 45–60 mph, especially during acceleration. The vehicle took an unusually long time to heat up, and the brakes were loud and squeaky. A few months later, after driving over a large speed bump, the airbag warning light turned on. During my next oil change, I mentioned this issue, along with a problem with the window sensor. They dismissed my concerns and told me to take the car to GMC across the street because they lacked the tools to diagnose it. At GMC Hurd, I was told the diagnostic service would cost 160 and that I would need to leave the vehicle for the day. At the time, I couldn’t leave the car because I needed it to pick up my children. Now, in November 2025, my inspection is due. I brought the car back to GMC, and they informed me that the vehicle had been in a major accident prior to my ownership. They discovered that the airbags had previously deployed and were stuffed back into the driver’s seat and sewn shut. I have never been in an accident with this car. I reported this to Grieco since they were the ones who inspected the vehicle in November 2023 and passed it. I believe they managed to get the car through inspection without properly or thoroughly examining it before selling it to me. They have dismissed my concerns and told me there is nothing they can do. This is outrageous, as the airbags would not have deployed in an emergency, putting my safety at serious risk.

When DRIVING the center console screen begins to glitch. It will begin to move around and try to connect to the internet, begin to track navigation, connect to my phone and make calls, or it will just started moving back and forth from the different screens. It also makes sounds while it is glitching. It's incredibly distracting when I am trying to drive. There are a number of online forums that have identified the problem in their same year, make, and model of vehicle. There were no warnings or messages prior to the problem. It presented itself about a year ago and I have just been resetting the battery as a temporary solution.

shift to park issues when placing the vehicle in Park

The contact owns a 2019 GMC Acadia. The contact stated that while driving at an undisclosed speed, the message "Steering Assist Fault - Drive with Caution" was displayed. The vehicle was taken to an independent mechanic, who retrieved DTC: P0128 (Engine Coolant Temperature Below Thermostat Regulating Temperature) and replaced the engine coolant thermostat. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was 55,114.

The vehicle will be in park, and a message will pop up saying "shift to Park check and advise". Took my car into the dealer shop to get this fixed their response was the cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the park position.

The put in park shows after engine is turned off, have to restart and shift out of park and back to park. This could take several times to accomplish.

Ongoing issue with the 2019 GMC Acadia, "Shift to Park" shows on dashboard when vehicle is in park. Unable to turn the vehicle off.

I do not have current recall on my vehicle, but my vehicle is experiencing the "Shift to Park" issue that many of the same year make and model mine is experiencing. I am unsure why my vehicle would not have one. It is messing up the transmission and I have only had this vehicle for a year from a dealership. I feel it is unsafe to drive as the vehicle does not always register that it is in park. I can feel the transmission slipping because of this. I would really appreciate some support for this. It is a 2019 GMC Acadia, which is also apart of the other vehicles that are apart of a lawsuit in Ohio and other states. This is a safety hazard for myself and my family.

I own a GMC Acadia 2019.The problem that is happening has to do wiyj "shift Park" message I am getting when I turn off my car. It is "IN PARK" but this message in instrument panel shows and keep beeping. After several shifting in different gears stop sometimes , sometimes not. I see some messages that there has been a recall, others saying not. I see a lot of Acadia 2019 owners are having this issue. I will try to coontact dealer but it looks like they are not helping others

I own a 2019 GMC Acadia SLT. The problem started after arriving at my destination and shifting into park. The message "Shift to Park" was displayed on the instrument panel.

This problem is a regular occurrence. No warning lights illuminate. The vehicle was taken to a dealer on my way home from a long trip. The service tech stated that there has been a LOT of complaints and he was surprised there were no recalls for this problem. The problem still persists on and off daily. The failure mileage was 49,000.

Due to negligence of gmc wright of wexford during the replacement of 3rd new transmission they did not clamp a hose together causing coolant to leak and my thermostat to come on n off. Causing further damage to my vehicle

The transmission keeps slipping, clunking, and not shifting correctly. Not shifting or down shifting correctly up and down hold or at stops. My husband is a trained mechanic and has confirmed through his place of employment that the transmission is failing. It hasn’t no yet been inspected by the manufacturer, police, insurance. No warning lamps, but the transmission temp rises to 270F+ In regards to the next question.. the issue is ongoing.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The issue was with the gear select switch and jumper harness, related to the "Shift to Park" malfunction in my 2019 GMC Acadia. Yes, the components were available at the time of the repair with the GMC dealer. 2. How was your safety or the safety of others put at risk? The vehicle would not recognize when it was in "Park," which prevented it from being turned off. This could lead to unexpected vehicle movement or battery drain, and creates a safety risk if the driver assumes the vehicle is secure when it is not. It also poses a hazard if the vehicle cannot be safely shut down in an emergency or in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was reproduced and confirmed by a GMC dealer during an appointment on July 22, 2025. They diagnosed the problem and verified that the gear select switch and jumper harness needed replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected and repaired by an authorized GMC dealer. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, a "Shift to Park" warning message appeared and the vehicle would not allow me to turn it off without shifting in and out of park multiple times. This first occurred on July 18, 2025, and continued until the repair was made.

Unknown My 2019 Acadia Denali has/is been repaired 6 times in 1 1/2 years for engine oil leaks , has had transmission repairs twice , radiator repair and replacement. Also suspension warranty work as well . I feel the oil leaks is and has been excessive and dangerous due to no warning lights never displayed to alert me to check oil

On my 2019 Acadia, the message shift to park keeps appearing on my dash when I shirt the car into parked. It's getting more frequent and when I called GMC it's a well known problem to where the lady taking my appointment says yes we are aware it's happening alot. They want to charge 800 to fix a problem that should be a recall. It's a well known problem and there has been cases and suits brought up and GMC will not make a recall on this even though the mechanic said I can't believe this hasn't been recalled. Can you help with making GMC do a recall in the Shift to Park. Thank You

Whenever parking the car and trying to stop (shut off) the engine it will randomly say “shift to park” and I cannot shut the vehicle off.

The contact owned a 2019 GMC Acadia. The contact stated that while driving at 20 MPH and attempting to adjust the steering wheel, the steering column and the steering wheel detached and fell in the contact’s lap. No warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the steering column and steering wheel needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 125,298.

Failure to be in park alarm when shifter is in park. Must play with shifter back into park to stop alarm bells and notice on dash. Supposedly there was a recall issued however not shown on this site per my vin #1GKKNXLS7KZ107842. Very irritating, please advise.

When I park and then turn the car off the car fails to recognize that the gear shifter is in the park position. As a result, the car doesn’t fully shut down, leaving the engine running or the electronics active. This drains the battery. I have seen this issue is recalled for other 2019 Acadias but don’t under why it is not recalled in mine. I’m afraid I’ll be out and about and unable to turn my car off resulting in a dead battery and being stranded.

Check engine light comes on, engine temperature gauge stops working engine fan runs on high only. I have replaced the thermostat/sensor once already and now it needs to be replaced again.

Check engine light comes on, temperature gauge stops working, driving assist reduced notification, engine fan runs on high only. Temperature gauge and sensor were replaced 27,000 mi ago when this happened before.

When the vehicle is put into park and I turn the vehicle off I get an alert on my console saying "Shift to Park". I called GM customer service and was told "harness" had been replaced in 2020. I bought the vehicle in 2021. Last year I had to replace the "harness" and it is doing it is now doing it again.

When I turn the ignition off it sends me a message that I must shift to park. The car is in park at that time that I get the message. I restart the car and move the shift to reverse or drive and move the car and place in park and that may correct the problem or I may have to do this once, twice even three times before it corrects. The warning bell will continue to ring and the radio continues to play until I can get the situation corrected.

When put in park it dings for a long time shift to park. I have read that this is an issue there has been recalls but mine is not on recall. However this does this like every other time I use it . I’m worried I will be left stranded with dead battery

The contact owns a 2019 GMC Acadia. The contact stated that while parking the vehicle, the gear shifter was shifted into park(P); however, the “Action Required Shift to Park” message was displayed. The contact shifted the gear shifter back and forth and then shifted into park(P) before the proper gear was recognized. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to take the vehicle to the dealer for diagnostic testing. The failure mileage was unknown.

When putting my vehicle in PARK and pressing the button to shut off my car, a warning appears on the dashboard saying “WARNING: PUT VEHICLE IN PARK.” & it is in park. I have to wiggle the gear shifter in order for the warning to go away and if it won’t go away, then my car won’t turn off. There was a recall on it in 2018 & I need mine fixed. Somehow, my vehicle was not apart of the recall but it needs to be. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

July 31, 2025 Our 2019 Gmc Acadia would not shut off in a parking lot, I was 45 minutes from home. A message on display says shift to park. This is a safety concern as the vehicle might not be fully secured in park, the vehicle won't shut off and will drain your battery. There is an ongoing class action lawsuit related to this issue, alleging that GM has been aware of the problem for some time but has not provided a satisfactory fix according to Lemon Law Auto Fraud. I called the gm dealer and they quoted me $500 to fix this issue.

Car gives “shift to park error” around every 5th time I turn it off. I have to turn the car back on and repark it to be able to actually turn off

Vehicle's "SHIFT TO PARK" warning is often displayed when vehicle shifter is in PARK and then the engine is turned off. Often takes several attempts to correct the problem by restarting and turning off the engine or by manipulating the shift lever while in PARK. These is a current recall for this issue with the same year, make, and model of vehicle. Checking the VIN against the NTSB recall list shows this vehicle is not included in the recall.

Last week, the coolant gauge , on our 2019 GMC Acadia, was reading below "C".... The "Steering Assist" warning was disabled on the on-screen display and the Air conditioning stopped working. Took the car to a mechanic, who read the codes.... Mechanic stated that all symptoms were based on a defective GM thermostat. The thermostat was "stuck-open" causing the "steering assist" to be disabled as well as the A/C from being disabled as well. It seems GM has updated the part since when the series of Acadia were manufactured. After getting it repaired, at of our pockets, we researched and noticed that thousands of other GM Acadia owners had the same exact 3 symptoms: (1) malfunctioning coolant reading (2) "Steering assist" disabled (3) a defective ("stuck-open") thermostat..... Symptoms were exactly the same for all parties involved. We have owned many vehicles never had a thermostat fail before 65k Miles.... It became a safety issue since the car disables the "steering assist" based on the thermostat being stuck open. Contacted GM corporate which stated unless a recall, there would be no compensation. GM needs to make it right for the thousands of GM owners whose car has the 3.6L engine In short, this is a major issue since the car's steering system is NOT working correctly We would like a recall to be initiated. Thank you.

Shift to Park Vehicle does not recognize the gear shifter is in the park position. Vehicle does not fully shut down.

When trying to park car, vehicle will not detect the shifter is in park. If the car does not detect its in park it will not turn off and stays running hampering your exit from the vehicle. This is truly an unsafe condition due to not knowing how to get the car to shut down as well as not knowing if the car will roll if you do get out.

Shift to park error message consistently displayed forcing repeated restarting of the vehicle so that it finally recognized that the vehicle was in park and would unlock the doors for safe exit from the vehicle. This was a known issue by General Motors and they have 2 class action lawsuits filed n the states of Ohio and Tennessee for this issue with well over 110,000 vehicles affected. General Motors refuses to acknowledge this defect and fails to issue a recall. Their only offer when I took this vehicle to a GM certified dealership was to offer 15% towards the replacement of the shifter assembly. The excuses made were the vehicle was out of warranty as well as over in mileage. I bought this vehicle used from an Acura dealership and accepted delivery of it on [XXX] with approximately 33,417 miles. I started to experience the shift to park error message at 36,013 miles in early May 2025. By the time I was able to receive instructions from GMC customer care and secure repair for this issue the vehicle mileage was approximately 37,000 miles. It is not a pleasant feeling to be trapped inside your vehicle until you can get it to finally recognize that the vehicle truly is in the park mode. With the hundreds of thousands of vehicles on the road with this issue I feel GM should recognize their problem and perform a vehicle recall. This flaw had been installed in numerous GM vehicles manufactured as early as 2017. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When vehicle is placed in park, it is still showing a "shift to park" message once car is turned off.

Since buying my 2019 GMC Acadia multiple times a day my auto shift to park will not allow me to lock my door as normal. It says there is no recall associated with my Vin Number however my particular Year, make and Model has the same issue. Please make this make since.

I noticed when I put my car in park and turn key off, it’ll ding to warn me to “shift into park” this been becoming a problem recently and it’s been happening more often.

About a month ago when I shifted my vehicle into park and shut the vehicle off, "Shift to Park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "Shift to Park" appearing. On 7/11/25, Arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off. When I went to leave for lunch, the car would not start at all, check the GM App and it stated "Critically Low Battery". A co-worker helped jump the battery and I was able to start the vehicle. When I went to leave work for the day, the vehicle would not start again with no notification as to why. My co-worker jumped the battery again and vehicle started now with all the system lights on dash staying on and warnings displayed. 7/12/25 Vehicle struggled to start and all system lights were still on. Later in the day, the vehicle would not start and all overhead, dash, display, taillights would not shut off. We jumped the battery and took the vehicle to our local dealer.

In March 2025 my 2019 Arcadia with only 44112 miles begin indicating a Shift to Park error message when I parked and shifted into park the error message showed on the instrument panel and the warning alarm sounded and would not stop showing the error message until I restarted the car and shifted from drive to park repeatedly. I couldn’t get out and close the door, and the warning stop, it would continue to sound the warning. The only way to stop the warning message and alarm was to stay in the car and repeatedly start the car shift to drive into park switch it off and if it still showed the error and warning, do it all over again. This could take up to several minutes and many tries. If I had of left the car all the warning would have been sounding indicating it wasn't in park. I didn't know if it was really in park or not and if not, the car could have potentially rolled off causing injury or damage. To try and determine what was the cause of this problem I searched the internet to find a solution, to do a reset or simple fix and discovered that GMC had known about this issue since 2016 and the only solution was an in the shop repair requiring replacement of some parts. The "Shift to Park" error in GMC vehicles is considered a safety issue by many owners and has led to class-action lawsuits. The issue, which prevents vehicles from recognizing when they are in park, can lead to the engine not shutting off, potential for vehicle roll away, and even entrapment inside the vehicle. On April 16, 2025 I had the repair done at Hayward Allen, Cadillac – GMC dealership, 2590 Atlanta Highway, Athens Georgia 30604. The total repair cost was $732.36 (invoice attached). ). I sent a copy of this invoice by email to GMC customer service. After customer service reviewed the amount they call and informed me they could only reimburse me a total of $73.24.

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in Ohio, but ours was manufactured in Tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the issue with the 2017-2018 Acadia models built in Tennessee.

I took my 2019 GMC Acadia in for an inspection and was informed that the toe links were loose and fail inspection. Upon researching this failure, I found that there is a recall for this, but my VIN was no included. I don't understand why not given what I'm seeing from other owners. I quote from the GMC Authority site: [XXX] "GM and the National Highway Traffic Safety Administration have issued a recall for certain 2022 model-year Cadillac XT5, Cadillac XT6 and GMC Acadia crossovers over an issue related to the rear toe links. The problem: affected vehicles may have a left-rear suspension toe link with a fastener that was not properly tightened during assembly at the factory. The GMC Acadia is built at the GM Spring Hill plant in Tennessee, but will soon be moved to the GM Lansing Grand River plant to make room for the Cadillac Lyriq. The Cadillac XT5 and XT6 are also built at Spring Hill and will remain there for the foreseeable future." Based on other feedback seen, it appears this should be a recall for my vehicle as well.

Shift to park light comes on and car won't shut off

Shift to park issue. This 2019 Acadia Denali has been serviced twice for a shift to park issue:(It’s a known problem that occurs when Acadia vehicles fail to recognize that the gear shifter is in the park position). The first time was under warranty in 2022 and it has just been serviced again for the same problem. The system is the same as the older GM recall for this problem and the recall should also include this model as well but unfortunately it does not.

My coolant thermostat went out, causing my AC and steering assist to stop working. I have spoke to multiple other people who have had this same issue with their GMC Acadia and I believe this should be a recall. It’s going to cost me $1200 to have this issue resolved.

Car has delayed shifting, and jolting when switching gears. Transmission temp gets up to 270 degree while driving

Component: Shifter Assembly & jumper harness Safety concern: Can't turn off vehicle - Carbon Monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running... Message in dash was present when I brought vehicle to dealer. Dealer also replicated No inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. GM is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair.. I was charged $778.98 for the repair, and GM's customer assistance center response to me simply was to file a complaint with NHTSA. My wife does not feel safe driving, as there is no guarantee vehicle will turn off. Dealer replicated issue when I brought to dealership. Dealer has replaced part and has them. Warning lights only appeared when problem reared itself, initially began about 60 days ago, but is not occurring on approximately 2 of 3 shut downs.

My 2019 GMC Acadia is now undergoing the same repair for at least the second time. This is the common issue known as the Shift-To-Park issue. You can read about it here - [XXX] Below are the commonly affected years: 2017 – Acadia 2018 – Acadia 2019 – several models (I own a 2019 GMC Acadia) 2020 – several models 2021 – Acadia and Traverse Despite falling into the year, make, model and issue - When I look up my VIN - No recall or warranty information is available, saying that my vehicle is NOT affected by this issue. However, this is now the 2nd (maybe 3rd) time I am having to come out of pocket to have this issue repaired. It originally happened in July of 2022 with around 40-44k miles on the vehicle. It is now happening again May of 2025 with around 72k miles on the vehicle. If I search further back, I imagine the first owner may have had the same work done too. Clearly this vehicle is affected by the issue buy according to my VIN it is not. GM (General Motors) told me that they offer no sort of help or reimbursement unless my VIN is associated with the issue. Can you guys please either add my VIN or extend out the warranty / recalls to ALL - Because this is absurd. My car doesn't recognize that it is in Park and stays on, preventing me from shutting down the vehicle / engine.

While driving the thermostat will go to zero and the steering assist is disabled. I have read a lot of forums that this is a known issue. The only way to reset it, so we have A/C is to disconnect the battery and it will last a day or two and do the same thing.

“Park to shift “ warning keeps showing up when shift the gear to PARK.

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to fork over $1300 to have it repaired.

Our Arcadia 2019 with 40000 miles has shift to park problem. 2017 thru some 2019 had recall notice and were fixed by GMC. Why doesn't it apply to this vehicle. We had to pay $1500 to dealer. There is an obvious problem and they have admitted it. Time for government to step in or do a class action lawsuit looks like they are filed by state

The contact owns a 2019 GMC Acadia. The contact stated that occasionally while attempting to park the vehicle and shifting the gear selector into park(P), the message "Please Shift to Park" was displayed; however, there was no warning light illuminated. The contact was unable to turn off the vehicle during the failure. The local dealer was contacted; however, the vehicle was not diagnosed. The contact was informed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 77,000.

I am receiving a "Shift to Park" notification on most instances that I shift the car into park. When this warning engages, the car will not allow me to turn it off as it does not recognize that it is in park. After researching this issue, I found that there is a GM Recall for 2017-2019 GMC Acadias for this very issue. However, my VIN is not included in the recall so I do not qualify to have the issue fixed and would have to pay a substantial amount out of pocket.

When I park my car it beeps and says my car is not in park. Many other models of the 2019 GMC Acadia, along with other GM vehicles, may be affected by a "shift to park" recall. This recall addresses a defect where the vehicle may display a "shift to park" warning message even when the vehicle is actually in park, potentially preventing the ignition from being turned off and the key from being removed. This is exactly what my car is doing but they say my VIN is not included in the free fix. I brought my vehicle after it died to a GMC dealership and they said it will cost 1,000 to fix. My safety is at risk because I drive to different locations as a therapist and I often drive home at night in remote locations.

Some times when vehicle is shifted into park it doesn’t recognize it is in park. I have to turn the vehicle off and restart it, shift into drive and back into park. Sometimes it takes a few times. My neighbor has a 2018 Traverse and had the same issue.

The contact owns a 2019 GMC Acadia. The contact stated that upon reaching his destination and shifting the vehicle into park, the vehicle failed to recognize that that the shift lever was in park. The contact stated that after restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The shift to park warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 61,000.

I have had intermittent issue with a message to shift the car to park when I shut it off. It was in park. If I wiggled the shifter it would often correct. That went on for a few years on and off. Lately it was more persistent. I brought it into the dealer and they replaced a harness and a switch. Seems that a harness would not go bad unless it had a manufacturer defect. I have seen a lot of reports on this issue on online blog sites. Seems to be a common problem. The problem with this defect is that when it is sin that mode, you cannot safely secure the vehicle and warning bells keep ringing. So the vehicle cannot be left like that and expect it to be secure.

When shifting into Park the car still states to "shift into park" on the dash and will not fully shut off. i still need to take the car into the dealer for service to fix. This seems to be an issue.

For 3 weeks now, my dash keeps telling me to shift to park when my gear shift is already in park. Car will not allow me to secure it because it thinks the car is not in park!

I have a 2019 GMCAcadia Denali with less than 60000 miles. The problem I have with the vehicle is I get a error that say "Park to Shift. I don' know if it is in park or not. I am afraid that it isn't in park and will create a safety issue and injuries. It is my understanding that the same problem with the 2020+ GMC Acadia and is listed in a RECALL. Why isn't 2019 not included in this recall?

When you go to park the car and put it in park the car says shift to park with it already being in park. It is concerning that the vehicle is not recognizing it being in park

Im a travel nurse and I was working in Vermont. As I was driving on the highway in New York on my way back home a shift to park light came on, a stabilitrak light came on, power steering light came on, ABS light came on, and my check engine light also came on. My vehicle started slowing down as I was driving and my lights on my dashboard were turning on and off and my speedometer was not working. I was able to pull to the side off the highway so I could get out of harms way. I made a call to OnStar for help and they asked to if I made it to a safe location. As the car was still on I was able to take the next exit and ended up in an auto zone parking lot. As I made it in the parking lot I turned the vehicle off but only the engine turned off but everything else stayed on and the shift to park light kept coming on when the vehicle was in park. I was in the parking lot for 3-4 hours freezing in my vehicle until onstar came to tow my vehicle. By the time onstar came my battery in my car had drained and it was a new battery. I was told that I would have to contact auto transport to transport my vehicle to Louisiana at the dealership where the vehicle was purchased. I paid $1600 to transport my vehicle back home and I had to find a way to make it back to Louisiana. I didn’t have a credit card so a friend of mine was able to rent me a vehicle to get home and I paid a total of $1700 on a rental because the dealership in Louisiana couldn’t give me a time or date the vehicle would have been finished. I have been to the dealership 3 times now for the same problem in less than a week. I have paid $1500 altogether to fix damages on my car that I noticed other vehicles with the same make and model had the same issues. I never had a problem with my vehicle before everything just started happening all at once. I’m currently having to pay for car rentals to get to and from work and to make sure my kids get back and forth to school. My vehicle in at the dealership again for the 3rd t

Our 2019 was repaired back in 2021 for a "shift to park" issue. This same issue is happening again after 2 years of being repaired. We see that there is a major issue with GMC vehicles and there have been recalls for this same exact issue. GMC Coleman, Lawrence NJ is refusing to fix problem under a recall. We would like this to be covered or reimbursed.

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "P." However, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at Walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (Auto Revival in Justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

Driver side blind spot not longer works. When driving the blind spot indicator just stopped working a month ago and I didn't take notice until I almost hit another car. I contacted gmc about this issue as well and was also told there isn't any recall for this and it would have to be diagnosed by there mechanics. There were no other issues prior to this. Also the "shift to park" warning has been popping up for 3 days now when my car is in park. My car won't complete shut everything off until that warning is turned off. I called GMC of puyallup and was told only certain vin qualifies for the recall for the gmc 2019 acadia. That's absolutely ridiculous! I can't exit my vehicle until the car senor knows my vehicle is in park which is a major concern and safety issue because my home is on a slope.

My GMC is in the repair shop for the alert (shift to park). I was once again unable to turn off my car and place it safety in park. This is a known issue and GMC Dothan states the 2019 GMC Acadia with my vin number is not on recall?? This is a know dangerous safely issue.

I have a 2019 GMC Acadia with 59051 miles on it, I get regularly oil changes and maintenance but it’s need a transmission. How is this? The mechanic tells me that there is no ETA when one will be available when he called to get one. This lets me know that there is a problem with the transmission and they probably should have a recall.

The contact owns a 2019 GMC Acadia. The contact stated upon attempting to turn off the vehicle, the instrument panel remained operable with the message "Shift to Park" displayed while the gear shifter was already in park(P). The contact shifted out of park(P) and shifted back to park(P) several times until the vehicle responded as needed. The contact stated that the failure recurred, and the vehicle failed to successfully turn off after several attempts, causing the battery to become drained. The vehicle was then towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 72,000.

I would park my car and try to turn off car. The car would not turn off. The car continued to ding the car remained on. The safety issue is the car wouldn't turn off. After many many times shifting from park to drive it would finally park, this happened every time using the car. I discovered the same exact issue is a recall on 2017 & 2018 GMC Acadia our exact car ! Called the dealer explaining SHIFT TO PARK issue. Brought the car to Buick GMC of Mahwah they noted in fact it was SHIFT TO PARK issue. Two days later came in for the car they would not cover problem. Cost $950.00 for exact recall the 2 years prior. Also, contacted GMC corp. they were no help just said had no recall. Our car is 2019 Acadia with 27,236 miles.

When I shift the car into park, a message pop up in the window to shift the car in park and keeps beeping.

I randomly get a "shift to park" warning even though the vehicle is in park. It looks like there has been this same issue with older years but not my vehicle according to the VIN.

Our car has the well know shift to park issue but shiws no recall. Is it possible GM might fix this defect?

I’ve taken my car to the dealership twice for transmission issues. One time the engine/transmission light came on, they kept it for a month and told me they didn’t find anything. Wrong. 2 months later I took it back because it felt like it wouldn’t change out of gears and felt lint the transmission was slipping, they told me they me since it wasn’t a light on they couldn’t check it without a code. I then had to take it to another dealership because a code came back on and they said it was something. Four months later my transmission went out while I was driving down the hwy. I have a 2019 gmc Acadia. I had the same similar codes on 3 different occasions.

The part broke on my vehicle. Part is on national backorder. I'm expected to be without a vehicle til mid December. I was told no one in the state of Louisiana has the part. This has to be affecting a lot of vehicles if this is true. I love my GMC and I hope they make this right. Radiator surge tank inlet hose is the GM part.

When putting vehicle in park, it doesn’t always sense it is in park. Will sometimes have to move it back and forth for a couple of minutes.

The "Shift to Park" error warning comes on even though the vehicle is in park. The vehicle will not turn off. I had this issue with my 2017 GMC Acadia. They tried to fix it once, but it came back. I see in the 2019 version that they have added an audible dinging to the warning. I would have thought after at least 2 years they would have resolved this issue. They just made it more annoying by adding the dinging.

The contact owns a 2019 GMC Acadia. The contact stated that upon arriving at her destination and moving the shifter into the park position, the vehicle failed to recognize that the vehicle was in park. After which, a message displayed reading "Please Shift to Park". The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 93,000.

I am constantly getting a “shift to park” warning after putting my car in park. My car sometimes will not shut off because of this. It’s a safety issue for me because the car is not registering that it’s in park and my battery could very well die while I’m out with my children. This is a common complaint from what I’ve researched and needs to be fixed by GMC.

The check engine light came on 12/2023. The vehicle was taken to Pep Boys and AutoZone in MD, WalMart and O'Rilley in Bastrop, LA, O'Rilley in Midlothian, TX. They could not find any problems with the vehicle. I took the vehicle to GMC in Plano, TX. THey charged me for a new battery but the check engine light remained on after I picked up the vehicle with a newly installed battery. The dealership said it would eventually go off. I took the car to Automotive Solutions in September 2024 and they can not find anything wrong with the vehicle. The car can not pass Texas inspection with a check engine light on. There is a large group on FB having this same problem. August 2024 the car will recognize when it is shifted into park. Sometimes it rolls after puting the car in park.I took the car to Automotive Soulutions in September 2024 and they can not find anything wrong with the vehicle. There is a large group on FB having this same problem. I took the car into a GMC dealership in MA because i hit a curb in 2021. The steering wheel feels loose. I took the car in 2022 & 2023 for the same problem. The dealership charges me for repairs but there is a reoccurring steering problem. Other drivers have noticed this problem with my vehicle.

After roughly 7000 miles of use the 235/55R20 102V Goodyear Assurance Weatherready tire has a bulge in the sidewall. There are no scuffs or scars on the tire to indicate an impact caused the bulge, it appears there is some sort of separation within the layers of the sidewall. I asked a Goodyear retailer to inspect the tire and they said it's automatically considered impact damage if the bulge is in the sidewall and Goodyear would not warrant such damage even though there is no evidence such as cuts, scuffs or scars. The tire inflation is to manufacturer's specifications and the tire isn't loosing pressure. DOT 1M78AJA5R purchased Oct 22, 2023 date code 3622

When I shifted to Park and hit the button to turn the car off, it continuously chimed and flashed the Shift to Park message on the dashboard. It would not allow me to fully turn off the car, stating I was not in Park, even though I was. I would have to turn the car back on, shift into drive or reverse, move forward or backward a little bit, hit the brake a few times, put it back to Park, hit the button, and hope it would turn off. It usually took four or five times of this routine before it would finally turn off correctly. It began happening more and more frequently over the course of a week by the time I could get it into the dealer. This is a safety issue, as the car was not fully in Park, and leaving it that way would have drained the battery as well as not allowed me to lock the doors while parked in my driveway. Thankfully, I have an extended warranty (car has 55,000 miles) and only had to pay my $200 deductible, but it was an over $500 fix. As this EXACT SAME issue is prevalent in these cars and was recalled on my same model in previous years, I feel the recall should be extended and these expenditures reimbursed.

Vehicle does not know it's in park. Can't turn off vehicle. Must shake or beat the shifter knob for vehicle to see it's in park.

The Shift to Park feature malfunctions. Although my car is in Park it does not recognize it, gives me a 'Shift to Park' message and won't allow me to shut off the car. My car not correctly recognizing what gear it's in is a significant danger. This problem was a recall in 2017-2018 GMC Acadias but my car produced the same issue and was not recalled. The component was replaced by an IG Burton dealer. There were no other warning messages prior to the issue occuring.

As previously reported by other owners of a 2017, 2018, 2019 Acadia- the “shift to park” message appears once I have put my car in park and turned it off. I have to restart my car, move the shifter to reverse, back up a tad bit, and put it back in park for the message to go away so I am able to turn my car off.

My radio is going crazy. Like going through every radio station, calls people. Its a distraction. And after researching how to fix I noticed thousands of people have the same problem. Almost cause an accident because of the distraction and this is obvious problem in GMC.

Purchased this vehicle with 49,000 miles on it. Currently, it has 55,000. When I shift the car into park and turn it off. I am met with a consistent ding and error messages displaying “Shift to Park.” With this error message I am unable to fully turn my car off, it drains the battery and I cannot lock my car door. I have to turn the car back on and mess with the shifter which sometime takes a longtime. I cannot just leave my car on and drain the other components; it’s frustrating. I called my local GMC dealer. I told them about the current issues with these cars as it isn’t a secret that this is a common problem. I pointed out the TBS on this make and model and I’m expected to pay for this out of pocket because my powertrain warranty ended June 30th 2024.

Last week I parked in a large public parking lot and attempted to turn my car off. I received a notification in my dash to “shift to park” even though my car was already in park. I was unable to turn the car off or lock the doors. I ended up having to leave. I have now gotten this message six times in the past week. It can take up to twenty minutes to get the car to turn off so I can exit. Yesterday upon returning to the car I showed an error message as soon as I started it that the parking brake needed service, stabilitrak is disabled and steering assist is disabled- drive with care. As I tried to exit the parking lot, I found it almost impossible to turn the steering week. I pulled over and restarted the car, releasing the steering wheel so I could get home. This morning, all of the service lights were on and periodic warnings flashed on my dash throughout my drive to work. I contacted the dealership and was told that there is a recall for this exact issue on the 2015-2018 models of my car. I have a 2019. This is certainly a dangerous issue that should be proactively fixed and is clearly still present in years that are not being included in the recall. I was told my car was one month past its warranty and told I could pay 250$ for the issue to be assessed and then they could quote me on a fix. The dealership acknowledged that this is an issue they regularly fix.

See attached document for complaint.

My car will not shut off as I am parked and “shift to park” is alerting me. The car keeps beeping. I have to re-start it multiple times and shift it in and out of park for it to finally go off. This last time it took 25 min to shut my car off.

Shift to park sign appears and doesn’t disappear until I turn and off the car multiple times. It’s been retuning problem for the past two months.

When vehicle is shifted to park, the “Shift to Park” warning illuminates and the vehicle is unable to shut off. Have to play around with the gear selector for several minutes in order to be able to be shut off. Looks like GM has known about it for a while and has done nothing. Has been occurring on ours for about a year now.

When shifting into "park", the vehicle displays a warning that vehicle failed to shift into park. Thr vehicle will not shut off and continues to run

When attempting to park vehicle, the alert "Shift to Park" populates and the car will not completely shut down. This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off. If it's not in the proper park position, the car can continue running, battery drainage and possible roll out of place. This also causes issues with the transmission not shutting off. I have not had this particular vehicle inspected, but contact with dealer service departments confirms continued complaints of this issue and it has not been addressed by GMC/General Motors. Problem has been occurring at various times over last 3 years.

When shifting to park and turning car off I get notification saying “shift to park” even when the car shows it is parked on the gear shift and dashboard screen.

During a routine oil and filter change the technician noted that the "rear tow links are excessive play in them." Several GMC vehicles have had numerous recalls to tow links over the years. Dealership suggested the repair and confirmed services were not covered under warranty. After further research into the repair there are countless forums and complaints about GMC vehicles needing tow link replacement. Photos of the original tow links show minimal wear and tear.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Infotainment system continuously changes screens without being touched. No matter what screen is displayed, it will change on it's own to various other screens. How was your safety or the safety of others put at risk? While I was driving I was using my GPS via CarPlay and the directions were displayed on the Infotainment screen. The screen started changing to other screens and at one point changed to the back up camera. I was almost in an accident because I was unable to see the directions and frightened and confused when the back up camera appeared while I was going forward on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I took the car to the dealership while it was still under warranty and they told me it was due to me using CarPlay and that my iPhone just needed to be updated. I updated my phone and the problem never went away. So now I've stopped using CarPlay and the problem is still occurring. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings. The problem first appeared in late 2020 early 2021. I have a video recording of the issue as well. Also when I Google the issue lots of other owners are complaining of the same issue.

My vehicle didn't shift into park all the way or the ADAS didn't register it. I would have to hit it quite hard with my palm to make it register. This happened for 3 months straight and finally stopped as sudden as it started. I tried to report it to GMC and was told there wasn't such an issue.

Shift to park will not work. Sometime after 20 try’s it may work once but I have to disconnect the battery to turn off the car. I’m beside myself and cannot keep doing this. This is a real safety problem. I have children in my car and Gm says there is no recall and I am expected to pay 800.00 and then it is not guaranteed.

The contact owns a 2019 GMC Acadia.

When I put my car in park and try to turn it off, the dash shows an error message "SHIFT TO PARK". The car will either not turn off the ignition or allow me to leave the vehicle or lock/unlock the doors. It alarms incessently--even when trying to move the shifter around. Takes several times of restarting and shifting to get it to clear so I can put it into park and exit the vehicle. Local dealer is charging me over $2000 to repair the transmission control shifter assembly; BCM low signal; in-line shifter wire harness jumper--exactly one month after my warranty expired. It's a KNOWN Acadia (and other GM vehicle) issue--per several bulletins--NA-19-206 as an example.

When I park my car and go to turn it off, it says "Shift to park". The dash indicates that it is in park and it will not allow me to turn the ignition off or lock the doors.

Vehicle placed in the park position on several occasions, but indication from monitoring system shows not in park position, vehicle rocks back and forward when foot taken off brake pedal. indicator requiring me to remove shifter from park and place back in park several times before indicator acknowledge vehicle in park. Transmission jerks and stalls when initial drive train mobolized and leaking fluid from transmission. Dealer never acknowledge issue after several visits, was told at last visit after over two years of complaining that seal was bad in transmission. Approximate dates of incident is over a 2 year span.

I would put my car in park but it would not let me turn the engine off, I would put it back in drive and then park again but it wouldn’t let me turn the engine off. I displayed a message that I needed to put the car in park. I repeated the process and then later it would let me turn the engine off. This happened several times. I took it to my car dealer and they fixed the problem but I had to pay for the repair. They said if there was a recall, they would refund my money. I saw where this same problem was a recall for my vehicle up to 2018. My car is a 2019.

Purchased a 2019 arcadia 1st owner the transmission crashed at 30461 miles. the transmission started slipping,parked it and took it to the shop. there were no warning lamps... the Chevrolet dealer diagnosed the issue,metal flakes all in the sample of transmission fluid ( replacement required) I have reached out to GM customer service and now waiting for a reply but there is a recall on the year and model of my vehicle.

My vehicle just hit 39K miles, it has all of a sudden started giving me a Shift Into Park warning. The sensor is not registering that its in park and will not let you turn car off. There is a recall on the 2017-2018 vehicles for this issue and but many report an issue with the 2019, when I called GMC they would not fix. How to we go about having this included in the recalls?

The contact owns a 2019 GMC Acadia. The contact stated that upon parking the vehicle and attempting to shift the vehicle into park(P), the "Please Shift into Park” message was displayed.

The vehicle was taken to the dealer, who diagnosed a failure with the transmission control module. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 11,000.

Unnecessary safety feature sounds and alerts distract driver's normal driving and viewing habits. Any which could be turned off, have been. Every time the car is started, there is a message that these warnings have been turned off. The message never goes away and stays on the entire drive time unless manually turned off.] These type of messages need to turn off after a short delay.

it ask to shift to park while already in the park position

After raining door locks on every door will not work. Won't lock or unlock, manually or by using the key fob. Something seems to be getting damp and shorting out . After a day or 2 the locks will work just fine when everything dries out.Seems to be a safety issue if I can't exit the vehicle. The rear hatch is the only door that works when this happens. What is the problem and the solution? This happens every time it rains. Had it to the dealer and they couldn't find the problem.

Shift to park issue. Car will not go into park. Car will not shut off. Sometimes shifting back and forth or jiggling the shifter will work. Dealer replaced shifter assembly at a cost to me of $777. This was done last week. So far so good, but GMC knew about this problem for quite a while.

Shift to park malfunction. When I put car in park, “shift to park” lights up and beeps. I have to wiggle the gear shift up a bit to get it to go off. Takes several minutes at times. This started about 4 days ago. I have an appointment at the dealership tomorrow. 68,300 miles on my vehicle. When I researched, several others complained about the Acadia’s shift to park malfunction.

Transmission flares going into and out of second gear cause to vehicle to feel as if its about stall out. Especially on hills. I had a vehicle almost run in to the back of me because of the decrease in acceleration.

In August 2021, I placed my vehicle in park and pressed the vehicle on/off button and received a message on the dashboard that stated "Shift to Park", even though the vehicle was in the off position. I was unable to turn my vehicle completely off (remained in auxiliary mode) and unable to lock the vehicle. I took my vehicle to a Chevrolet dealer who notated the issue was inspected and verified with a repair procedure under TSB 19-NA-206. The service record reads "This condition is caused by the park switch in the transmission control not pulling BCM signal low to electronically show part position. Removed and reinstalled transmission control, installed new shifter harness and added wire harness jumper". In February 2024, the repairs completed by the dealer failed again, and this time the entire shifter (transmission control) needed to be replaced. The TSB that GM has put forth does not "fix" the issue, just puts a temporary band-aid on the problem until the vehicle is out of warranty and the customer is forced to pay for the repairs themselves. Without the vehicle registering it is park, the vehicle stays active and the customer is unable to lock or secure the vehicle, putting the safety of the customer at risk. It is also unknown if the vehicle is actually in park, putting those around the vehicle in danger of getting run over.

Engine consuming extra oil due to failed piston ring. Also, may be the cause of a coolant failure code. Burning through excessive oil and check engine light came on. Also, prior to these warnings, I've felt hesitation when accelerating and when the car changes gears. I was told by a shop that I need a new engine. This causes a dangerous situation because the car could just stop working while driving or in traffic.

I owned a 2019 GMC Acadia Denali with surround vision system (rear camera). In December 2023, my rear camera went out and almost caused me to hit someone while backing up. I don't totally depend on the rear camera when backing, but this time when I turned around to look if anything was behind me I didn't see no one. I took my vehicle to the dealer to get it checked out and to repair it. They found that the vision process module was bad. The technician found that the vpm had internal malfunction and corrosion due to water intrusion damaging vpm completely. found code B101D for internal failure and not responding to any programming or commands. Replaced vision processing module at a cost of $1348.90. I wrote to GM explaining the problem and request reimbursement. As of today, no response from GM.

My 2019 GMC Acacia SLT would not go into park to allow me to shut off my vehicle. It ran for over an hour before it finally went into park. This was dangerous as I had a young child to pick up in a busy part of town and I had to leave it running to try to get help. With a 3 year old child this was crazy. This is not the first time it has done this. My car had a recall and whomever fixed it didn’t do it. I feel this needs to be fixed properly now.

I am having trouble with my 2019 GMC Acadia. I keep getting a message that says shift to park. How many I get this repaired at no charge?

Shift to Park - car will not turn off after putting in park. Car is still running after several attempts of hitting the power button to turn off. I have had to replace the battery twice in the same year. I have brought this issue to the dealership from the beginning of purchase and was unsuccessful.

Headlights are so dim that we will not drive the car at night. Dealer's service manager says that he knows about the problem but "there's nothing I can do to fix it". I see a few similar complaints on this site, but nothing as to who to contact to get the problem solved NOR any action on this on the part of the NHSTA. Where do we go from here?

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I am scheduled to take the vehicle in for service on 1/11/24. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation.

Shift to Park car would not turn off. Had to start car, then go forward and reverse several time so the vehicle would finally recognize it was in park. - this has been going on for almost one year on and off. “Steering Assist is Reduced Drive with Care” making it hard to steer. The get Service “Stabilitrak”, “Side Detection Temporarily Unavailable”, All Wheel Drive Off, “Battery Saver Activated”, Services “Battery Charging System.” All lights went out and the car went dark! I was unable to drive the car, had to be towed. - this has happens twice. The first time was on October 2023, the mechanic put in a new alternator, thinking this was the problem. The second time happened 11/29/2023, mechanic is still trying to diagnose the problem/problems. This car has left me stranded and in fear to drive it due to the fact that I lose all vehicle driving ability!! It

The vehicle part involved is the right rear suspension adjust toe link. I did not ask the GM dealer to save the old part. The old part is not available for inspection. The replacement GM part number placed on the vehicle is 84606181. On December 4, 2023 during the annual State inspection of my vehicle the GM dealer advised me that the right rear suspension part listed above showed wear in the bushing and the vehicle fails the state inspection because this is a safety issue. In order to pass the state required safety inspection I would need to have the suspension part replaced. This part controls how the vehicle tracks down the road when driven to prevent vehicle swaying from side to side. Since the GM dealer inspected and confirmed the above I authorized the dealer to replace the worn out part and also perform a wheel alignment as recomended by the GM dealer. Prior to the info provided above their were no warnings, noises, or signs that the right rear toe link bushing was warn to the extent that it required replacement. This first notice I had on the potential problem with my vehicles suspension is described above. I was advised that the above part is a common part that requires replacement on my type of vehicle.

The touch Display screen. It has started to constantly go through every setting on the car while driving. I’ve tried turning the screen off. It works for a few minutes and then turns itself back on. It will change radio stations. It will make phone calls if a phone is detected. It is a constant distraction while driving GMC is obviously aware of the problem. You can call a service center. They will tell you that it happens all the time and that the part will cost you around 800$ not including service charges. With how many people depend on display screens in today’s technological ways. It’s only a matter of time before a serious accident occurs from this, if not already that hasn’t been reported. Also this affects more than just my vehicle. It’s across most of GMC models. Several public forums related to this issue.

On 9/24/23, I was driving both locally & the highway in S. I., NY. Suddenly the Adaptive Cruise Control feature shut off & on repeatedly & kept flashing (Adaptive Cruise Control unavailable) almost causing an accident, then I pulled over and shut off the system. The next day on (9/25/23) I brought the car to GMC & Buick Dealership at 1855 Hylan Blvd, S.I. N.Y. 10306. After a couple of hours, the manager Carlos Mercado tells me they need to do further testing tells me to come back on 10/04/23. I arrive at 9:00am for my appt. After three hours, I asked him what’s going on? He tells me that there are two Modular’s in the vehicle & needs to be reprogramed & updated. He says the mechanic that was working on it can’t do it & to come back. I knew at that point I was being scammed. On 10/11/23 at 10:15am he comes & tells me the vehicle is ready. I go to the register tells me at first was $671.00. I said for what? It’s outrageous! He says oh it’s electrical. I asked him did you replace any parts? He says no. replace any wires? He says no. I said if this was a recall I wouldn’t pay for it because its a safety issue. So he must have felt guilty and says I give you a discount & the price now is $555.56. So I says to him this is a lot of money for this. He tells me it was labor. I said to him I have been watching the whole time that the vehicle would sometimes be in the service area & the parking lot with the mechanic hardly working on it. I said to him do you think I’m a fool because I’m a woman unaccompanied by a man you take advantage of me. So they would not release the car unless I pay for it which I did with a credit card. On 10/12/23, I filed a complained with GM for a full refund, and explained that the program was faulty & only need an update and I was contacted by Charlie from the Executive team on 10/17/23. Tells me he will reach out to the dealer. On 10/23/23 he tells me they can only offer $250 in reward points which I declined, because they know I wont use it.

"shift to park" warning message. Unable to shut vehicle off or leave vehicle. Shifter is in the Park position but vehicle does not recognize it is in Park and will not shut off. Vehicle has never been in an accident. No residual code. Dealer will assess but not covered under any existing warranty or recall. Out of pocket expense. TSB 18-NA-297; replaced by 19-NA-206.

I placed the car into Park and the Shift to Park indicator light came on even though the car was in park. I was unable to turn the car off. I had to shift the car in and out of gear and sometimes drive the vehicle to finally get Shift to Light off and be able to turn off the car. This happened 3 times within one week. I read of numerous instances on-line where this same condition occurred in other GM vehicles. I took to Joseph GMC for repair and was charged $855.12 for repair since the car was out of warranty. (The car only had 28,058 at time of service.)

Vehicle refuses to turn off due to "Shift to Park" error being displayed. Vehicle also gives "Driver assist unabled. Drive safely" message and AC will not cool and vehicle coolant gauges will not work.

After noticing my AC was not cooling, I began receiving a “steering assist is reduced drive with care” notice every time my car was started. My car is more difficult to steer. It has been assessed by a certified mechanic and found that the coolant temperature probe is malfunctioning and the ECM will either need to be fixed or replaced. Due to malfunctioning power steering, I do not feel safe driving this vehicle until it is fixed.

There is a shift to park issue. When I place the shifter into park and the car is in park, I turn the vehicle off and I have a message action required “shift to park”

Shift to Park is not working properly. Have to start engine and shift to park as much as three times to get the light to go off and radio and bells to quit dinging. I can't tell if car is in park or not and could be dangerous to leave it.

Getting a “Shift to Park” message when the vehicle is already in park

When the car is put In park there is a message that appears on the display when pushing start/stop to turn the car off "shift to park". The car has already unlocked and it turns off and restarts but the message keeps popping up

The contact owns a 2019 GMC Acadia. The contact stated while driving 55 MPH, the electric power steering (EPS) warning light illuminated, displaying the message "Steering assist Might be Inoperable". The contact stated that following the message being displayed, the vehicle overheated. After restarting the vehicle, the vehicle returned to normal functionality, but the failure had since become a regular occurrence. The vehicle was taken to the dealer, who diagnosed a failure with the thermostat. The vehicle was repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 70,000

The contact owns a 2019 GMC Acadia. The contact stated that while attempting to shift to park(P), the transmission failed to shift into park, and the contact was unable to turn off the vehicle. The contact also stated that when she started the vehicle, the reduced steering power warning light illuminated, and the failure caused the battery to be replaced once. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,000.

There is a “shift to park” message. The vehicles fails to recognize that it is in park and display a message urging me to “Shift to Park.” When this happens, I am unable to shut the car off, and this could cause my vehicles to roll away if it is not properly in Park. I would have to constantly wiggle and move the electronic shifter to get it to recognize that the shifter has been placed in the ‘Park’ position. This has resulted in me getting stuck in my car until I get the message to stop, which often time takes several tries and minutes.

The contact owns a 2019 GMC Acadia. The contact stated while shifting into park(P) there was a beeping warning chime, and the gear shifter symbol was flashing.

When vehicle is put into park and you go to shut off the car it gives a message to shift to park. Diagnosis reveled that there is a service bulletin SB#19-NA206 which tells the mechanic to replace the the shift control assembly and add jumper harness to cure shift to park message when vehicle is turned off. Previous years of this vehicle model were covered under recall . This model year should also be under recall for this problem.

Car won’t go into park. This happened with my 2018 Acadia and now my 2019. It keeps saying shift to park for the car to turn off when it already is in park

The contact owns a 2019 GMC Acadia. The contact stated that the check engine warning light was illuminated. The low oil message was displayed. The contact added oil to the engine.

The vehicle would continuously not register as being in park.

The steering assist code comes on , the temp gage goes down , and it’s immediately hard to steer . All the lights come on , and drained the battery, this has happened several times

Traveling at interstate speeds the vehicle had an short in the Body Control Module due to the HVAC drain leaking into the vehicle. The vehicle displayed a series of alarms brake, steering, and shutoff. We had no power, steering, brakes, or lights. The issue was discovered by Dave Sinclair dealership. It had been in for a sensor issue 3 months prior.

Shift to park error every time I park my car. It takes multiple times of shifting and what not to get the vehicle to shut off. I will be making a appointment with my dealer.

Vehicle is constantly giving “shift to park” error. The steering mechanism has also been compromised, and the vehicle makes persistent jerking motions with accelerating. This could be quite dangerous.

The contact owns a 2019 GMC Acadia. The contact stated while parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed, though the gear shift indicator had displayed that the vehicle was in park(P). The contact stated that she restarted the vehicle, shifted from park(P) to drive(D) continuously until the vehicle responded as needed. The contact stated that the failure had been recurring. The dealer was notified of the failure and an appointment was scheduled for a diagnostic test.

I just purchased this vehicle and within a day, it was already giving an alert that something was wrong. Says "action required, shift to park". My car was in park. It was not shutting off due to the notification, which leads your battery to drain. The next day, as I was driving with my kids, the headlights start flickering, and then shut off. It left us driving in the dark and nearly causing a wreck because someone didn't see us coming because it was too dark. The dealership said they look at it, so I don't know what will happen moving forward. It's definitely not safe unless the issue is addressed.

Im getting new tires on my car and was told the alignment cannot be done due to the rear tow links needing replaced. I was told it's a known issue with Acadias and should be covered under a recall I called my dealership and it's not a recall.

"Shift to park Warning light" comes on when turning off vehicle when vehicle is in park.

The contact owns a 2019 GMC Acadia. The contact stated that while the vehicle was idling and shifting into park(P) the “Shift to Park” message was displayed. The contact stated that the vehicle was in the park(P). As a result, the contact was unable to turn off the vehicle. The vehicle was then taken to the dealer where it was diagnosed; however, the contact was not informed of the result. The vehicle had not yet been repaired. The manufacturer was notified of the failure, but no further assistance was provided. The failure mileage was approximately 34,000.

For a few months I intermittently get an engine light on, the temperature gauge goes to zero, the AC stops working, and an error that driver assist in unavailable. This will happen for a fee days and return to notmal where everything is fine. This happens on and off again. I google searched this and it is a huge problem with GMC Acadias. I used an obdII scanner and get a P0128 coolant error when this happens even though the temperature is fine. I just recently went over the new car warranty and GMC will not tell me if this is covered or not.

“Shift to park” message frequently appears and unable to turn vehicle off, will drain battery if left on. First appeared infrequent within 1st year of lease, brought to dealership service, they were unable to reproduce and stated they did not know what was wrong with vehicle if they couldn’t reproduce the message. Fast forward 4 years, I have now purchased the vehicle and message and condition appears very frequent almost daily. Returned to dealer service was advised by customer service manager “ I know exactly what it is it is in the gear shift” but since car is no longer in warranty I would have to pay out of pocket. I attempted to explain that I did I bring it back when it would have been on warranted and was told they couldn’t find anything wrong!!! I have replaced battery multiple times due to power drain from not being able to clear “shift to park” message. Last battery lasted less then 1 year!! I feel GMC is aware of the issue and did not take care of problem when it was under warranty and is now forcing the finiancal burden to replace/repair parts to me!!!

Thermostat gets stuck, generally in open state. AC also is disabled in this condition, soft code (no MIL) mentions "limited steering available" and temp gauge on dash goes to 0. Hard code eventually comes (solid Check Engine light on the dash). Code, MIL, and temp gauge can be cleared and fixed by disconnecting battery negative terminal and reconnecting it, and it will run consistently for a while, though it will return. Online there are no thermostat modules for this engine available (3.6L V6, also in Cadillac XT6, Buick Enclave, and Chevrolet Traverse) showing that thermostat replacement is widespread. Online forum searches also describe widespread thermostat issues for this engine, at roughly $1200 per fix. A reliable thermostat is critical for long-term engine functionality, and should not need replacement at half of design life (~75-80k miles). Though this one tends to fail open instead of close, overcooling of an engine still could have its own issues, and failing closed could lead to engine overheating.

2019 Acadia originally displayed a shift to park message at 12K miles and vehicle was still under warrantee. New shifter harness was installed and a wire harness jumper added. GM covered the cost of repairs. At the time I was told hopefully the repair fixes it but a chance it won't and will need to bring it back in. Two years later at 36K miles it occurred again but was out of bumper to bumper warrantee so GM would not cover and dealer would not give any discount. Both the dealer and the GM claim rep I talked to were not able to adequately explain why this is not considered in the powertrain warranty which is still valid. GM did reimburse 50% of the cost of repair but I am still out ~$380. This issue seems well documented across numerous models / years of GM products.

The shift to Park locks up and will not allow the vehicle to turn off. Receive an error message that the vehicle is not in Park.

There have been no reported recalls yet my vehicle is on it's third battery since purchasing it? How is this possible?

The electrical and gear shift failed, causing a problem that GMC calls “shift to park.” Even when the car is placed in park, the car does not recognize that it was placed in park and cannot be turned off, preventing the driver from leaving the running car. This is a known problem that multiple dealers are aware of and there even appears to be a recall and lawsuits on the 2018 Acadias. However, on my 2019 Acadia, which has the same problem as the 2018 vehicle, this is a problem that costs hundreds of dollars to fix. This should be recalled because it renders the vehicle a safety hazard because it cannot be turned off and it is a known GMC problem that they refuse to fix.

I’ve had 2 issues with the thermostat going bad. The official part is called the water outlet assembly that includes the thermostat. I’ve also had several others tell me they have had this issue.

The contact owns a 2019 GMC Acadia. The contact stated that after the transmission was shifted into park(P), the “Shift to Park” message was displayed. The contact shifted the gear shifter into several other gears and was able to turn off the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and confirmed that there was no recall associated with the VIN. The failure mileage was approximately 60,000.

Several times we were unable to put the vehicle in park which would not allow the car to be cut off. I went on line to read reviews about this kind of problem and found bulletin 19-NA-206 describing the shifter assembly as a common problem on this vehicle. A Gen shifter harness was replaced at a cos of $589 with a two year warranty and was told that this will probably happen again. (Gen Shifter Harness) We are now afraid to take trips now because we use to make many stops in small towns to visit relatives. My wife wants to get another kind of vehicle because of this problem. We have purchased four cadillacs and two GMC vehicles from Coulter Cadillac but no problems with the Cadillacs.

My 2019 GMC Acadia started having the known "Shift to Park" issue that is affecting these make/models. This is a known issue and GMC has not issued a recall for it, nor are they covering any cost of repair. When the car is put into Park, the screen displays a message that says "Shift to Park". This results in being unable to turn the car off. The vehicle will not lock either when the message is displayed. On several occasions, the car would not start because of this issue. We took it to the dealer and they are fixing the issue for just over $500 USD.

Steering assist warning came on and my wife panicked. She was on the highway and it came on and she could fill it in the stereo wheel. Temperature gauge stays on 0.

Vehicle has been bucking and jerking when trying to accelerate. Going up a hill is scary (especially with my kids in the car) because it slows the car down trying to find a gear. Dealership says it's a torque converter but since so many Acadia's are being recalled for transmission issues, we feel ours should be included as well. Dealership is making us pay for a transmission flush which doesn't make sense because if it weren't for these issues, we wouldn't need to have a flush.

The contact owns a 2019 GMC Acadia. The contact stated while driving at an undisclosed speed, the vehicle hesitated to accelerate with the "Steering Assist Reduced, Drive with Care" message displayed. Additionally, the temperature gauge remained on cold. The vehicle was taken to the dealer; however, no failure was found. The failure recurred, and the vehicle was taken back to the dealer, where it was determined that the thermostat needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 44,000. The VIN was not available.

While driving the temperature gauge shuts down completely to C - the check engine light comes on and a message appears on the dash saying "Steering Assist Reduce Drive With Care". Any air conditioning goes from cold to hot and the fan under the hood goes to high automatically and wont shut off. We have been informed that this is a known error that has existed for a long time now, with no recalls to date. I cannot schedule my vehicle for repairs yet because I do not have the money to pay for the repairs. They are saying that the placement of the thermostat and sensor, which need to be replaced in order to fix this problem, are located in a very difficult spot to get to. Saying that it will take upwards of 4-5 hours to get everything fixed, which increases the amount of money to fix this issue. My 2019 GMC Acadia just started doing this about 2 months ago and I have 54000 miles.

When I put my car in park and try to turn my vehicle off I get an error message saying “shift to park.” The problem is the car is already in park and I am unable to turn the off. I usually have to start the car back and drive back and forth before the car actually recognizes it is in park. Im concerned for my safety.

The vehicle’s steering assist reduced, drive with care notification came on. The vehicle lost steering assist control and made it very difficult to steer. The slightest move causes a major shift in the intended direction. This is very dangerous.

When trying to turn car off, shift into park, and a message is on the driver screen to "shift to park". The car is already in park. The car will not stop running unless the "shift to park" message is gone. After looking on internet, was able to toggle the shift gear button to remove the "shift to park" message. This started about 4 months ago, it did not happen all of the time. At first, I would have to attempt to restart the car, and then try to turn car off. After investigating this on the internet, was able to turn car off by toggling the gear shift button. This problem was not a surprise to the car dealership. Apparently it is a common problem, and a recalls have been made by GMC for this issue, but not for the year of my car. My car was no longer under warranty, so had to pay $348.04 to fix this.

The car is is giving a warning to Shift to Park even though the car is in park. GMC says this is a known issue and could become a safety issue but is not coving under warranty or recall.

Initial battery died completely when vehicle was 2 years old (17 months ago). This week got a steering assist drive with care message and everything pointed to codes signaling low voltage. Battery tested with a bad cell. GM will not cover the cost to replace a battery when not one but two have gone bad well before the middle of their earful lives. GM claims there is nothing electrical drawing from the battery causing both the go array. Bad customer service on GM’s part. Logically this issue should be covered as it is not a typical maintenance replacement. It’s something causing two batteries to go bad!

I have the shift to park error where my car is not recognizing that it is in park and will not shut off. I have been held hostage inside my car, late for work, etc because my car will not shut off because it is not registering that it’s in park. Also, my breaks are unbareably loud with whatever switch they made to the “new” brake material.

After exiting the highway onto a side road, the vehicle began to shake violently (like we were on a very bumpy road). I pulled into a parking lot thinking we had a flat tire. Then the vehicle suddenly came to a stop and would not move forward and would not move backwards. There was no flat tire, but I noticed that the front left tire was turned inward in the direction that the steering wheel was turned, but the front right tire was also turned inward at a much greater angle. At first glance, I could see behind the tire that the tie rod had detached from the front right tire resulting in no steering capabilities for the vehicle. The tie rod has a large bolt that attaches it to the tire, and the bolt was missing. Had this happened on the highway just a few minutes earlier, the resulting accident could have been catastrophic. I paid to have the car towed to the dealership and when the tow truck driver arrived he took one look at the vehicle and said "this should have never happened". The dealership could not explain how the tie rod lost the bolt and there was no visible damage to the tie rod. My concern is that had this happened at 60mph, the car could have flipped or the car would have been abruptly turned into the median wall at 60mph. Tried to upload images, but could not upload.

Get the message "shift to park" The car is parked but it is not recognizing that it is in fact parked. It makes it impossible to exit the vehicle and turn it off. To get the message disappear and exit the car the gear has to be wiggled. I checked this online and previous GMC vehicles were recalled because of this. And it has a possibility of hurting the transmission as well. This happens quite often. So there no exact date.

Gear shift notification problem. Unable to turn engine off after receiving "Shift to Park" message and the gear shift is visibly in the "Park" position. In addition, the doors would not lock. My wife was forced to stay in the unlocked running car in a store parking lot for 25 minutes, until the car just "turned off" on its own. Unsafe for a woman (or anyone) to have to do at 10:30pm. This puts drivers in a really vulnerable position. Vehicle taken to dealer Jan 30, 2023. Was told they were familiar with the problem.

I'm not sure what this is but I'm not reporting damage I'm reporting the factory model. This vehicle seating is not appropriate for the body size of the front of the vehicle. I've had two other acadias and I didn't have this type of issue. The side of the vehicle where the mirror is located is so large is can cover the view of two cars. And even adjusting the seat doesn't help. You literally have to lean up to loom out the front windshield to make sure you are in the correct place. It's a safety hazard and whoever manufactured this particular car did not do so well

Steering Assist reduced drive with care" displayed on screen when I was driving. The temp gauge stayed on C, Heat works fine, Happened for a few days.

Vehicle will not shift to park. Have to engage the parking brake to ensure vehicle will not roll away after shifting to park. Becuase the vehicle isn't actually shifting into park l, the vehicle will not shut off which drains the battery and leads to being unable to turnover the engine.

My car would not shift into park. The indicator in the center console would say that it was in park, but when I would shut it car off I would get a warning on the dash that said that I needed to shit to park. I started chocking the tires when I parked out of fear of the car rolling away or run over somebody. My wife would not always chock the tires. I took the car to the dealer today and they confirmed my issue. The dealer replaced a part on the transmission. The dealer has my old part. It cost me over $400.00 to repair. The dealer and manufacturer are aware of similar circumstances with this model. I started having issues two months ago without warning and the problem got steadily got worse. The car has 43300 miles on it. I have owned it since new. It has never been in any accidents.

2019 GMC Acadia started producing error code of “shift to park” around 32,000 miles. This malfunction is directly connected to a know a non manufacturer flaw in the shifting mechanism shifter switch an faulty grounding. The error code “shift to park” will not allow you to properly shut off or start the car causing potential safety threats to individuals involved. This error code is a know issue with the shifting mechanism GMC has been putting in Acadia models for the last 5 plus years with no proper resolution to correct potential hazard for consumers. Recall Bulletins are in place for some 2009-2017 models currently,but only a temporary fix. Consumers are expected to pay for repairs for a manufacturer defective part that doesn’t meet nhtsa requirements. I would like to add the 2019 models to this list. Vehicle was inspected by GMC dealership and master mechanic.

A week ago my car started having an alert on the dash saying “shift to park” when I was already presumed to be in parked. I was worried because the car wouldn’t turn off and stayed on dinging. I couldn’t leave my car because it was on (possibly having battery die or doors won’t lock, etc.) I researched it and it showed many GMC Acadias have done this and previous models has recalls. As a result, the vehicle could roll away once you get out of it, putting you and the people around in great danger. Also, you may not be able to restart the vehicle once the 'Shift to Park' message is displayed, making it a terrible inconvenience especially when you're in a hurry. I took my car in to be serviced and they said it was that I needed a “new shifter assembly” so $670 later and after reading that this is what mechanics first step is, but essentially may not even fix the problem kind of terrifies me. A recent recall report says that GM does not currently have a fix for the Shift to Park issue just yet, however, it does have fixes for "Shift to Park" messages that can appear in affected Acadia vehicles that are already in PARK On October 3, 2018, GM released a TSB entitled "Message Displaying Shift to Park When in Park" which instructed technicians to correct the defect by replacing the transmission control shift assembly. While there are some fixes for "Shift to Park" messages, GM still has no fix for the actual Shift to Park issue. What do we do? Pay a large fee for a possible half fixed issue?

Every time I go to turn off the engine it say shift to park and then I have to restart the truck and keep putting the shifter into park a couple of times for it to not happen.

Vehicles shift lever doesn't always go into "PARK" and when the 'stop' switch is pushed the instrument panel displays notice to "shift to park" even though the operator has already done so. The audio still plays after the vehicle door is opened. So I assume the vehicle is still using battery power.

I am getting a warning message to “shift to park” when I am already in park. I have to shift back and forth for the message to go away and am not confident if the suv is in gear or not. This apparently is happening with many GMC Acadias.

The vehicle is a 2019 GMC Acadia with 45,255 highway miles on it. On 1/5/23, I took the vehicle to the GMC Dealer for a routine Pennsylvania State Inspection. I was told that the vehicle's rear toe links were loose and that I would not pass the state inspection unless they were replaced. Upon some research, I found out that it is unlikely that toe links would be loose on a 4 year old car with 45k miles on it. Furthermore, to my knowledge, what causes threads within the toe link to loosen is improper adjustment. The first and last toe link adjustment was made as it was manufactured by General Motors. Looking into the issue, I noticed there was a number of other people online complaining about the same issue. Having no choice but to repair the vehicle in order to have a legal vehicle to drive, I was charged over $800 which included a wheel alignment which I was told was necessary after replacing the rear toe links. In addition, I noted that there was a recall for GMC Acadia vehicles manufactured from December 2021 to March 2022 regarding the same exact issue, and as you know, loose toe links can cause a loss of vehicle control, increasing the risk of crashing and thus putting my daughter's safety and other people's safety at risk. There were no warnings or signs of the toe link ever being loose prior to this inspection.

While driving the all the the service lights came on on the dashboard and the system as well as the stabilitrak notification. The car begin to not want accelerate and I had to put on the hazard lights on a drive very slow home. Upon arrival home the car would not start but would not power off either and the a "Shift to Park" warning message is displayed.

The contact owns a 2019 GMC Acadia. The contact stated while attempting to start the vehicle, the vehicle would not start. After several attempts, the contact was able to restart the vehicle however, the vehicle inadvertently stalled. The vehicle was towed to the dealer and the battery was replaced. On another occasion while the contact shifted the vehicle into park, the contact heard a beeping sound coming from the vehicle. The vehicle was taken to the dealer, but the vehicle was not diagnosed. The manufacturer was not contacted. The failure mileage was 28,000.

About five months ago, my GMC Acadia started displaying a warning when I would put the car in park, and try to turn it off. The engine would shut off, but the electrical portion of the car would stay on, and would not turn off, because the warning displaying said "SHIFT TO PARK". I have tried every conceivable way to try to get this to go off, but nothing works. My car has stay on for upwards of two and a half hours, to the point where my battery died in the car and left me stranded. There have been numerous accounts of this, as I had read them on forums, yet still no resolution has been published. I have tried taking it to be inspected, but nothing ever comes up. I have two very small children, and if I were to be in public and be stranded because my car wouldn't turn off.... I would be livid.. Also, because of this warning, it prevents the doors from being locked. That is another major concern for me, considering the day in age we're in.

Constant issue of doors not locking or unlocking with key fob. Doors do not lock when put in drive or unlock when put in park. Buttons on the door to lock/unlock do not work. Have had at the dealership 4 times and still the issue hasn't been fixed. They replaced BCM and Harness and the issue still comes and goes.

Vehicle will have a message on the dash that says “drive with care steering assist is reduced”, the fans will come on and stay on, and the temperature hand will quit working along with air conditioner. It has not been inspected, I am not sure if the steering assist being reduced could cause any harm to myself or others.

The contact owns a 2019 GMC Acadia. The contact stated while attempting to park the vehicle, the warning message to “Shift to Park” was illuminated. The contact was not able to shift the vehicle into park as needed. The contact turned off and restarted the vehicle however, the gear shifter failed to shift into park as needed. The contact manually turned the steering wheel from side to side while shifting the gear shifter until the vehicle responded and the vehicle was turned off. The vehicle was taken to the dealer to be diagnosed; however, the contact was unaware of the result. The contact was concerned that the failure was due to the transmission. The vehicle was not repaired. The manufacturer was contacted and stated that there was no recall for the failure. The contact was informed that the repair would not be covered. The failure mileage was 35,000.

The vehicle intermittently fails to recognize that it has been put into park, flashing a message on the dash instructing the driver to “shift to park” even when the gear lever have already been moved to the ‘P’ position. I find it amazing that GMC even has a Service Bulletin No.: 19-NA-206 to address the situation (Intermittent Shift to Park Message Displayed While Vehicle in Park) but yet I had to pay $561.47 for the repair to ensure I don't injure my passengers and/or others.

Shift knob stuck. Car will say shift to park after turning off car. Ended up draining battery. Needed to replace it after 34000 miles.

With the vehicle shifter in park and the dash indicating in is in park I get an error message stating to "Shift into Park." This has happened serval times in the last few weeks intermittently. I am very concerned this will strand my wife and child or lead to the vehicle unintentionally rolling away while unattended. While talking to several technicians at a GM test facility I have been told this was/is a common issue. While searching the NHTSA complaints multiple multiple complaints for this issue have bee submitted.

Can not fuel vehicle properly. Fuel nozzle continues to shut off unless you hold it at the slowest delivery possible. This is with all stations. Dealer says fuel tank has failed internally causing this problem. Cost to repair $1500.00. 51k miles

The middle buttons in the infotainment system do not work - only the buttons around the edges (top, left, right, bottom) work.

Car wont shut off..displays shift to park. Had to turn car off a handful of times before i got it to turn off.

"Steering Assist reduced drive with care" displayed on screen when I was driving. The temp gauge stayed on C, the a/c did not work and engine fan came on full blast. After a couple days of this, it went back to normal. Coolant was checked and full at correct level.

Gmc acadia keeps flashing the lamp that says to !shift to park, when the car is in park and will not turn off. Does not go off when I turn the car off and does not go off when I reshift the car to park. It takes several trys of putting it back in park then goes off, now it does this every time I park and turn the car off. I'm not the only one with this issue. Its been going on for over week now 38k-ish miles.

Intermittent shift to park message displays on the dash. Had to turn the automobile back on to start the engine then moved gear selector to drive then to park. At this point the message disappeared allowing me to turn off the automobile.

The Shift to Park warning message when shifter is already in park shows up on the dash information center. The gear assembly is not working properly, and the artificial intelligence does not recognize park when you are in park. You cannot turn the car off without repetitive turning car off and on and shifting back and forth between drive and park. I was going to live with this aggravation due to costly repair ($656.67), but I went online and found that the car may roll forward if it is not fixed in a timely manner and you don't know if it is in park causing danger if it rolls. Others say put the emergency brake on always. This is a safety issue. Jim Ellis said to bring it to your attention and also write a letter to GMC Corp. I also noted that there is a lawsuit against GMC as they have profited selling the Acadia with this defective gear assembly since 2012. This is the second generation 2017-2019 with the same safety issue problem. Also, you have to replace the battery due to the excessive usage it drains the battery ($219.12)

The contact owns a 2019 GMC Acadia. The contact stated that while parking the vehicle, the gear shifter was shifted into park(P) however, the "Shift to Park" message was displayed. The contact shifted the gear shifter back and forth and then shifted into park(P) before the proper gear was recognized. The failure caused the battery to drain. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 48,000.

When parking the suv and placing the gear shift in park, the notification system states “shift to park”. This has been happening daily for the last 3 weeks. Sometimes I can get the notification to go away when I push the button on the gear shift. Other times, I have to cut the car off and then back on for it to clear the notification.

'Shift to Park' appears on the dashboard after the vehicle is turned off and in Park. This issue can deplete the battery. The problem was confirmed by the dealer.

After vehicle is shifted into Park, "Shift into Park" message comes up. It requires you to restart vehicle, put in R, back into Park, sometimes jiggle the button, sometimes the entire shifter, sometimes drive around the block and start the process again. The message does not go away even if you exit the vehicle. 2017 Acadia had a recall for same issue, 2 years later still occurring but no recall. The repair is $600! GM offering nothing. Needs to be a recall, if you have an appointment it is sometimes 10-15 minutes of messing with the shifter ro driving around until you can shut your car off. I have been carrying tools and just disconnecting the battery if it won't shut off. Can't be 10-15 minutes late for work every day waiting for my car to agree it is actually in Park!

Vehicle has had a hard shift since 15000 miles, always told at dealership it was normal. At 87493 my check engine light came on and code P2097-00- I was told it was that I had a bad battery and GM would not provide me one. Light was reset. Now at 98000 miles, shifting harder (automatic) like a jolt and vibrates going up hill- told I needed transmission fluid changed, this did nothing. This was confirmed by dealership prior to fluid change and then the dealership would not set up another appointment. Had this confirmed also by an independent service center. Occasionally a light will come on to say shift into park, despite being in park. No other messages related to this.

My vehicle would not turn completely off, I would have to start it about ten times before the warning sounds and the yellow light on the ignition switch would go off. I took my Acadia to Rod Hatfield Chevrolet Lexington, KY. I was told that there was an internal short with the transmission shifter, the shifter and harness would need to be replaced. considering that I purchased this vehicle new, and it has 39,793 miles I feel like it should have been covered under the warranty however, it cost me $903.3. I have an open case with GMC who suggested that I contact you to see if my Vehicle Identification Number could be added to for recall.

Intermittent Shift to Park Message Displayed While Vehicle in Park, as detailed in NHTSA Bulletin 19-NA-206.

The headlights barely light up enough roadway to be of any use at night. Obviously can't drive with high beams constant. The only help is to use the fog/driving lights. However, that only lights up about 30 feet in front of the vehicle. Driving at night is hazardous to one's health as you cannot see far enough down the road to avoid anything that is imminent on the side of the road, you can not see to avoid anything on the side. PLEASE HELP. Also, the manual is explicit about not using aftermarket headlamp bulbs to try to correct the problem.

2019 Acadia will be shifted into park and parking break applied. Vehicle will then be turned off. When opening the door a message appears on the dash stating "Place vehicle into Park". It takes multiple times of turning on the car, Shifting into another gear, then shifting back to park for the vehicle to realize it is in Park to allow vehicle to shut off. It has happened multiple times. We then received an email from on-star there is a diagnostic code SAC001 (Battery Service) needs to be addressed. This is unacceptable for a vehicle to be this new and have electrical issues.

Can not see at night with low or high beams. Lights are very poor and dim. Transmission always feels like it's slipping( 50,000 miles ). Shifts hard.

I’m not sure but a warning came on that said steering assist reduced drive with care and my temperature gage and AC weren’t working all of a sudden when it happened

Once vehicle is in park and ignition is shut off, a message will show to "shift in park" when it is in park. When this message appears, it takes several times to shift the car back and forth in order for it to register that it is in park. This occurs occasionally...sometimes more frequent than other times. It just did it today and it hadn't done it in a couple of weeks. The vehicle will not turn completely off or lock until you can get the stick to register it is in park. Sometimes it takes me a second to get the message to go away, other times it takes several mins. Really aggravating! These models are not cheap. This has occurred for well over a year now. I purchased the car November 2019.

I purchased my vehicle brand new off the truck in march of 2020 with zero miles on it. Feb 2021 in negative degree weather, the heat on my vehicle stopped working. I called my local GM dealership and they told me they needed to diagnosed the vehicle. They had kept my vehicle for two weeks trying to diagnose the vehicle. It turned out to be the thermostat. they replaced that part on my vehicle. Now Dec 2021 I again have experienced the same problem this time it was in a blizzard. Dealership told me it cant be the same problem, however it will be another two weeks before they can get my vehicle in for service and do not have a loaner vehicles for use. I purchased a new vehicle with warranty as I have two small children and am currently pregnant.

The contact owns a 2019 GMC Acadia. The contact stated while driving at 45 MPH, the accelerator pedal was depressed however the vehicle failed to increase in speed and started to jerk. The “service stability track” warning message was displayed. The failure was intermittent. The contact took the vehicle to an auto store where there were no codes reported by the diagnostic tool. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,600.

The contact owns a 2019 GMC Acadia. The contact stated that while driving 40 mph, the brake pedal was applied but failed to slow the vehicle down. As a result, the contact rear ended a Chevrolet Tahoe. The air bags failed to deploy. A police report was filed. There was no reported fire. The contact sustained soreness to the body and medical attention was provided. The vehicle was towed to an independent body shop for structural damage. The contact stated that after the vehicle was in her possession the safety restraint system service message was displayed. The fuel gauge went from full to empty in seconds and the engine stalled. The vehicle was taken to the local dealer where the brakes were bleed. The vehicle was repaired. The manufacturer was notified however, no further assistance was provided. The failure mileage was 33, 717.

After shifting the car into Park and pressing the start button to stop the engine, the message "Shift to Park" appears, and the engine does not shut off. This issue happens intermittently, but it has sometimes taken several minutes of shifting and re-shifting to get the car to turn off.

Headlights are so dim that it makes driving difficult and unsafe, particularly in rain and on rural, unlit roadways. Virtually unnoticeable change in lights when changing from dim to bright, and no side lighting whatsoever to allow visibility of deer/wildlife, etc. in ditches. Even turning from a highway onto a side road in rural areas is difficult and dangerous. I have found numerous complaints from others regarding this model, but no recalls or solutions.

Shift to park message appears post vehicle being in park! Vehicle has been inspected per Jeff Schmidt auto group (formerly Valentine Buick GMC, Inc! I was told shifter needs replaced as well as harness! Very disappointed do to the fact I brought this vehicle in 2019 off the showroom floor and 3 yrs later there’s a problem with my shift gear with 36k miles on vehicle..

When I put my 2019 GMC Acadia in Park shut the car off get a message to put the car in park. The radio does not go off, not able to lock doors. Displays that message. Have to keep putting it out of the park and after 5 or 10 minutes message finally goes off and it will let me lock doors. These last couple days it had done it every time I drive it

I have a 2019 GMC Acadia that has had no vehicle damage and less than 29K miles. The vehicle has condensation in the headlamp on the right front. No damage at all to the vehicle. Clearly a defect in the seal. Doesn't even have to rain and moisture will be apparent in the headlamp. GMC has offered to pay 60% of the repair costs of a $400 part and $1200 labor bill. This clearly needs to be investigated since they have had issues in the past of headlamps issues in the Acadia models and others.

The Rear Hood was opened to get groceries. All of a sudden the hood came down on my back. I had to push the hood up manually, and tried to close with remote or with button on the hood but the Rear hood would not close. I then had to manually close the hood. On August 11, 2021 I took the car to the dealer and they replaced both Rear Hood Struts that wear leaking fluid. This SUV is only 2 years old with 16000 miles and should not be having these type of safety issues that can potentially be life threatening.

When I put Shifter in PARK, the dash indicator states the car is in PARK. I then push the Start/Stop button to turn the car off, but the dash displays car is not in PARK. Sometimes the car will not shutoff or the car just beeps until I push the Stop/Start button. I cannot lock doors to leave the car. When this occurs or when left in this state the battery runs down, which leaves me stranded. This is certainly a safety issue on various levels. It the car really in Park! What if it on a hill and starts to roll into me or someone else.. Scary!!

Occasionally my vehicle will say "Shift to Park" when I turn off the vehicle, but the vehicle is clearly in Park. It has been happening more frequently lately. I have researched this problem and it appears it has been a problem with several other GMC Acadia's as well.

We are experiencing the "SHIFT TO PARK" issue on our 2019 GMC Acadia at 44,000 miles. We have been told we need to pay $200 for the fix PLUS more than $200 for the battery which has undoubtedly been impacted by the first issue. Needless to say, we are not happy that we'll be charged for a known GMC issue and we are aware there are class action suits around this issue in various states. We have been loyal GMC owners, but we are now concerned about the safety issues this presents our family. Ironically, we are searching for a new truck at this time and this recent hardship will impact our brand choice now as well as in the future. Please let us know how this issue might be rectified.

WE HAVE HAD OUR 2019 GMC ACADIA AT TWO DIFFERENT DEALERSHIIPS, RECENTLY WE HAD IT AT THE DEALERSHIP WHERE WE PURCHASED IT NEW IN 2019. THE DOOR LOCKS KEEP MALFUNCTIONING WHERE THEY EITHER WORK OR DON;T WORK AT TIMES. MY WIFE AND CHILD GET LOCKED OUT OF THE VEHICLE WHICH IS A SAFETY ISSUE. THE DEALERSHIPS HAVE WOIRKED ON THE VEHICLE A HALD DOZEN TIMES BUT THE ISSUE IS STILL OCCURRING. THE ORGINAL DELAER NAME IS COCHRAN GM OF ROBINSON IN PITTSBURGH PA. THE DEALER HAS BEEN GREAT WITH US BUT THEY STILL CAN'T FIND THE ISSUE.

WHEN I GOT TO WORK THIS MORNING, I PUT MY 2019 ACADIA IN PARK AND TRIED TO TURN OFF THE CAR. AN ALERT POPPED UP THAT SAID, "SHIFT TO PARK," BUT THE CAR WAS ALREADY IN PARK. I TURNED THE CAR OFF AND THEN BACK ON AND IT CORRECTED, BUT THIS IS THE SECOND TIME IN TWO DAYS THIS HAS HAPPENED.

DURING TAKEOFF WITH MODERATE ACCELERATION AROUND 1500-2000 RPM THERE IS AN EXHAUST DRONING/BUZZING SOUND FORWARD OF THE FRONT PASSENGER AREA. VEHICLE HAS BEEN TO DEALER TWICE, THE FIRST TIME THEY REPLACED THE ENTIRE EXHAUST SYSTEM, BUT AFTER 6 MONTHS THE SAME SOUND RETURNED. THE SECOND TIME THEY TRIED TO LOOSEN AND RETIGHTEN THE EXHAUST BUT THE SOUND RETURNED IMMEDIATELY AFTERWARD. THE DRONING SOUND IS MORE LIKELY TO OCCUR AFTER EXHAUST IS WARMED UP.

"SHIFT TO PARK " MESSAGE STARTED COMING ON THE DISPLAY EVEN THOUGH THE VEHICLE IS IN PARK. ONCE THIS MESSAGE COMES ON, I AM UNABLE TO TURN THE VEHICLE OFF. I HAVE TO KEEP PUTTING THE VEHICLE IN GEAR AND PARK AGAIN SEVERAL TIMES UNTIL THE MESSAGE GOES AWAY. I HAVE VIDEO OF THE ISSUE BUT DONT SEE WHERE IT CAN BE UPLOADED. THERE IS ALSO A CLASS ACTION LAWSUIT IN CONN ABOUT THIS ISSUE.

WHEN ACCELERATING THE VEHICLE EXHAUST OR ENGINE IS REALLY LOUD LIKE THERE'S AN EXHAUST LEAK.

WHEN I SHIFT THE CAR INTO PARK AND TURN THE CAR OFF, THE CAR INDICATES "SHIFT TO PARK" AND DINGS UNTIL I MOVE THE GEAR SHIFT AROUND FOR SEVERAL MINUTES, AND THEN THE INDICATOR STATEMENT AND SOUND STOP. THIS HAPPENS APPROXIMATELY HALF THE TIMES I PARK AND TURN THE CAR OFF.

AFTER PLACING MY CAR IN PARK, AND TRYING TO CUT OFF THE ENGINE, IT ALERTS ME TO "SHIFT TO PARK" ... I WILL HAVE TO RESTART MY ENGINE, PUT IT IN NEUTRAL AND THEN BACK TO PARK, AND TRY AGAIN TO SHUT OFF THE CAR. SOMETIMES IT WORKS ON THE SECOND ATTEMPT, BUT USUALLY TAKES 3-4 TIMES OF CUTTING ENGINE OFF AND ON, SHIFTING FROM PARK TO DRIVE TO PARK AGAIN. IF YOU ATTEMPT TO EXIT THE VEHICLE, THE HORN WILL START TO HONK, AND ALARM GOES OFF. THE CAR IS CLEARLY IN PARK, THE SHIFTER CAN NOT MOVE FORWARD ANY FURTHER, AND THE INDICATOR SAYS ITS IN "PARK" IT IS ONLY AFTER YOU PRESS THE START/STOP BUTTON THAT THE ALARM INDICATES IT NEEDS TO BE "SHIFTED INTO PARK"

FIRST IT SAID PARKING WASN'T WORKING CORRECTLY . THEN I CHECKED TO MAKE SURE THE PARK BRAKE WAS OFF , THEN WHEN I SHUT THE ENGINE OFF IT SAID IT WAS NOT IN PARK AND THE DASH LIGHTS STAYED ON ..

VEHICLE DOES NOT RECOGNIZE IT'S IN PARK. VEHICLE WON'T SHUT DOWN COMPLETELY,IT HONKS HORN AND BEEPS INSIDE AND WON'T LET YOU LOCK DOORS OR RESTART CAR. HAVEN'T NOTICED IT ROLLING AWAY LIKE MANY PEOPLE STATE... JERKING THE SHIFTER SEEMS TO GET IT WORKING SO FAR .. HAVEN'T BEEN STRANDED YET.VEHICLE WAS STATIONARY IN A PARKING LOT

THE VEHICLE DID NOT STOP PROPERLY WHEN THE BRAKES WERE APPLIED HARD TO AVID A COLLISION.

MY GMC WAS ABLE TO GO 45 MINUTES WITHOUT THE KEY FOB I HAVE TO HAVE THE KEY FOB WITH ME TO DRIVE MY CAR AND THAT DIDN'T HAPPEN I WAS ABLE TO DRIVE WITHOUT IT

PUT VEHICLE ON PARK AND MESSAGE APPEARED SAYING THAT IT'S NOT PARKED I GOT TO BACK UP AND PULL FORWARD A COUPLE TIMES UNTIL IT RECOGNIZES THAT VEHICLE IS ON PARK THEN I CAN TURN THE ENGINE OFF

THE VEHICLE WAS NOT TAKEN TO A DEALER OR AN INDEPENDENT MECHANIC TO BE INSPECTED OR DIAGNOSED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 20,000.

I GET AN ERROR MESSAGE 'SHIFT TO PARK' WHEN IN PARK I AM TRYING TO TURN OFF THE ENGINE. THEN IT DINGS, WON'T LOCK, ETC.

FIRST TIME BACK IN JUNE 10TH, 2020, I TOOK IT IN BECAUSE OF "REMOTE NOT DETECTED" THEY COULD NOT DUPLICATE THE PROBLEM, FEW HOURS LATER, SAME DAY AFTER I PICKED THE CAR UP IT WENT HAYWIRE WHILE PARKED. IT THREW ITSELF INTO THEFT MODE, WOULD NOT LET US MANUALLY LOCK THE CAR, ELECTRICAL WAS STILL ON BUT ENGINE WAS SHUT OFF, ALARM, WINDSHIELD WIPERS, AND LIGHTS WAS GOING OFF WHILE I HAD IT TOWED TO THE DEALERSHIP. THIS TIME THEY'VE TOLD ME, THE A/C CONDENSATION FRIED THE CPU MODULE BECAUSE THE ONLY THING KEEPING WATER OUT OF THE CPU WAS A TRAY. SEPTEMBER 9TH, 2020 I TAKE IT BACK INTO THE DEALERSHIP BECAUSE AGAIN THE CAR KEPT READING "NO REMOTE DETECTED". THEY CLAIMED IT WAS MY "DASH CAM" THAT CAUSED THE ISSUE. OCTOBER 14TH, 2020 THE CAR AGAIN WENT HAYWIRE WHILE IN MOTION. THIS TIME IT THREW ITSELF INTO THEFT MODE, ALARM WENT OFF, WIPERS, WAS READING LOW FUEL (FULL TANK) STEERING ASSIST TURNED ON AND OFF, BRAKES STARTED LOCKING MID BUSY STREET, STEERING WHEEL TIGHTENED ALSO. I BARELY COULD TURN IT INTO A NEIGHBORHOOD STREET TO GET OFF THE ROAD. I HAD THE VEHICLE TOWED BACK TO THE DEALERSHIP AGAIN, THROUGH MY TRIPLE A PLAN FOR THE SECOND TIME BECAUSE I WAS "OUT OF THE AREA" THAT THEY COULD SEND A TOW TRUCK TO. THEY TELL ME AGAIN CONDENSATION GOT INTO THE CPU AND WASN'T EVEN SURE IF IT'LL HAPPEN AGAIN IF I CONTINUE TO RUN THE A/C. I PICKED THE CAR UP THE NEXT WEEK AND ON OCTOBER 25TH, 2020 THE CAR AGAIN WOULD NOT READ THE KEYS. EVERY INCIDENT BUT OCTOBER 25TH, 2020 INCIDENT, I HAVE LET A SUPERVISOR FROM GM KNOW OF THE SITUATION, HIS NAME IS [XXX] EXT. I HAVE RECORDED EVEN PHONE RECORDS OF EVERY INCIDENT THAT'S OCCURRED. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

AFTER JUMP STARTING CAR BECAUSE OF DEAD BATTERY DECIDED TO DRIVE TO DEALER 1-2 MILES AWA.Y. MY WIFE FOLLOWED ME IN CAR. WHILE DRIVING DURING THE 1-2 MILE TRIP THE STEARING WOULD LOCK UP (QUIT WORKING) AND THE BREAKS AS WELL.THIS LASTED SEVERAL SECONDS AND RESULTED IN TOTAL LACK OF CONTROL AT 35-45 MPH ON A CITY STREET. THE ALTERNATOR WAS WORKING PROVIDING ELECTRICITY TO THE CARS SYSTEMS. AS BATTERIES FREQUENTLY FAIL I BELIEVE THIS IS A CLEAR AND PRESENT DANGER TO THE OCCUPANT AND OTHER VEHICALS ON THE ROAD.THIS OCCURRED ON SUNDAY OCTOBER 17, 2020

GETTING A "SHIFT TO PARK" MESSAGE WHEN THE CAR IS IN PARK. IT WON'T LET YOU DO ANYTHING LOCK THE CAR, BELLS GOING OFF, NOTHING AND SOMETIMES IT TAKES 20 MINUTES OR LONGER TO KEEP TRYING TO GET THE CAR INTO PARK.IT WOULD DO IT EVERYTIME I GO TO DRIVE IT.

TL* THE CONTACT OWNS A 2019 GMC ACADIA. THE CONTACT STATED THAT THERE WAS AN ABNORMAL SOUND INSIDE THE CABIN OF THE VEHICLE WHILE DRIVING WITH THE WINDOWS ROLLED DOWN. ADDITIONALLY, THE AUTOMATIC EMERGENCY BRAKING ACTIVATED WITHOUT DRIVER INPUT.

THE CONSUMER STATED THE DVD WOULD TURN ON IT. THE DEALER STATED IT COULD BE DUE TO A MISSING REMOTE THAT WAS NOT INCLUDED WITH THE VEHICLE. THE PARKING BRAKE WOULD ACTIVATE INDEPENDENTLY. THE CHECK ENGINE LIGHT WAS ILLUMINATED. THE STEERING AND ENGINE REDUCED POWER THE WARNING LIGHT ILLUMINATED. THE HEADREST DVD PLAYER DO NOT PLAY THROUGH THE SPEAKERS. THE WIRELESS PHONE CHARGER WAS OFTEN INOPERABLE. THE SECOND GEAR DOES THE NOT SHIFT PROPERLY. THE DASH AND RADIO PERIODICALLY LOSE POWER. THE WINDOWS MAKE A LOUD OBNOXIOUS NOISE WHEN ROLLED DOWN. *JS

I HAVE HAD FADING ON THE PLASTIC AROUND THE WHEEL WELL, THE HEAT WILL CHANGE TO COOL AIR WHILE DRIVING WITHOUT ANYONE CHANGING IT. THE A/C WILL GO FULL BLAST ON IT'S OWN AND THEN ALL OF A SUDDEN CHANGE THE FAN SPEED WITHOUT ANYONE TOUCHING IT. THE DEALER HAS TOLD ME IT WILL ADJUST ITSELF BY 10 DEGREES, NEVER HEARD ANYTHING LIKE THIS BEFORE. THE FADING PART THEY JUST PAINTED OVER IT AND THAT WAS THE FIX. THERE ARE LINES IN IT NOW AND THEY DID NOT PAINT THE ENTIRE PIECE SO IT DOES NOT LOOK RIGHT. THIS CAR IS PARKED INSIDE WHEN HOME, THIS SHOULD NOT HAPPEN. I HAVE HAD THIS CAR IN THE SHOP WAY TOO MUCH SINCE I BOUGHT IT WITH DENTS HAPPENING ON PARTS ALL OVER. I DRIVE TO WORK AND BACK MOSTLY. 2 DENTS HAVE HAPPENED IN THE DEALER LOT WHEN THEY HAD IT OUTSIDE WAITING ON REPAIRS. WOULD NOT BUY IT AGAIN.

TL* THE CONTACT OWNS A 2019 GMC ACADIA. THE CONTACT STATED WHILE MAKING A LEFT, HE WAS UNABLE TO VIEW ANY OBJECTS SUCH AS ANOTHER VEHICLE NEARBY DUE TO STRUCTURE OF THE VEHICLE. THE CONTACT WAS CONCERNED THAT IT COULD RESULT IN A CRASH. THE VEHICLE WAS TAKEN TO LOCAL DEALER JIM HARDMAN BUICK GMC, INC. LOCATED AT 1592 BROWNS BRIDGE RD, GAINESVILLE, GA 30501 AND WAS INFORMED THAT THE VEHICLE WAS FUNCTIONING AS DESIGNED. THE VEHICLE HAD NOT BEEN DIAGNOSED OR REPAIRED. THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 23,000.

I HAVE EXPERIENCED ISSUES WITH THE SHIFTER OF THE VEHICLE TWICE NOW AND IT HAS RESULTED IN REPLACING THE SHIFTER AT LEAST ONCE. 6 MONTHS LATER AND AFTER AN INITIAL REPLACEMENT THE SHIFTER HAS GONE OUT AGAIN. THE SHIFTER REFUSES TO MOVE OUT OF THE PARK FUNCTION. PRIOR TO THE SHIFTER GOING OUT THE CAR WOULD SAY SHIFT TO PARK EVEN THOUGH THE CAR WAS ALREADY PLACED IN PARK. I BELIEVE THE ISSUE TO BE AN ELECTRICAL PROBLEM. THE MIDDLE SEAT BELT IN THE SECOND ROW OF THE VEHICLE HAS ALSO STOPPED WORKING. *TR

AT 500 MILES PAST THE WARRANTY EXPIRATION THE RADIATOR DEVELOPED A CRACK ALONG THE TOP SEAM. THE DEALERSHIP SAID IT WAS A MANUFACTURES DEFECT AS THE VEHICLE WAS LESS THAN TWO YEARS OLD. GMC DECLINED TO REPLACE THE PART BECAUSE IT WAS 500 MILES PAST THE WARRANTY ALTHOUGH THEY DID NOT DENY IT WAS A MANUFACTURING DEFECT. I HAVE A GMC CASE NUMBER DOCUMENTING MY DEALINGS WITH THEM. I HAVE PHOTOS FROM THE DEALERSHIP SHOWING THE CRACKED RADIATOR, AS WELL AS AN EMAIL STATING IT WAS A DEFECTIVE PART. I HAVE THE RECEIPT AND I HAVE THE ACTUAL RADIATOR ITSELF. I NOTICED THE RADIATOR LEAKING ON MY GARAGE FLOOR WHEN IT WAS STATIONARY. THIS WAS 10 DAYS AFTER IT WAS LAST SERVICED AND THERE WAS NO ISSUE AT THAT TIME. THE DEALERSHIP SAID IT WAS NOT CAUSED BY IMPACT, BUT JUST THAT THE SEAM SPLIT AT THE TOP OF THE RADIATOR.*DT*JB

SHIFT TO PARK . MY VEHICLE TELLS ME SHIFTER IS NOT IN PARK WHEN IT IS . I WAS INFORMED THERE WAS A RECALL. THIS IS MY GOING TO BE THE THIRD TIME THEY FIX IT . THIS VEHICLE CARRIES MY KIDS TO SCHOOL AND WORK ON A DAILY BASIS , I DON'T FEEL VERY SAFE DRIVING MY FAMILY IN THIS VEHICLE . *TR

MY 2019 GMC ACADIA HAS ABRUPTLY AUTOMATICALLY BRAKED WHILE DRIVING BETWEEN 10- 15 MPH AND WITHOUT ANY CARS NEAR THE VEHICLE. IT SLAMS ON THE BRAKE LIKE IT'S THE PARKING BRAKE AND MAKES A GRINDING NOISE.. THIS HAS OCCURRED ON 2 DIFFERENT OCCASIONS. AFTER THE 1ST TIME THE SERVICE PARKING BRAKE LIGHT CAME ON. THE DEALERSHIP SAID IT WAS RELATED TO A FAULTY BATTERY BECAUSE I RECEIVED AN ONSTAR NOTICE ABOUT MY BATTERY. . IT OCCURRED AGAIN AFTER HAVING THE BATTERY REPLACED. *TR

CAR AUTOMATICALLY SHUTS OFF WHEN DRIVING MULTIPLE OCCURRENCES OF THIS HAPPENING

MY 2019 ACADIA KEEPS BEEPING WHEN THE CAR IS IN PARK AND I SHIFT IT OFF WITH AN ERROR MESSAGE 'SHIFT TO PARK'. I HAVE TO TURN THE CAR BACK ON, SHIFT THE CAR OUT OF PARK AND BACK INTO PARK. I AM NOW DOING THIS 10 TIMES OR MORE. I CALLED THE DEALER AFTER RESEARCHING THAT THIS IS AN ISSUE WITH THE CAR AND HAVE NOT ISSUED A RECALL. THIS IS A PROBLEM. BY STARTING AND TURNING OFF MY 10 TIMES I AM PUTTING A STRAIN ON THE STARTER. I AM AFRAID THE CAR WILL ROLL WHEN IT'S OFF WITH THIS ERROR MESSAGE. *TR

WHEN I COME TO A STOP AND PUT THE CAR INTO PARK I GET A MESSAGE TO SHIFT TO PARK BEFORE I CAN TURN CAR OFF

9 DAYS AFTER TAKING POSSESSION OF MY 2019 ACADIA, WITH LESS THAN 900 MILES ON IT, IT STOPPED WORKING. THE FIRST TIME I HAD A PROBLEM I HAD GOTTEN OUT OF THE TRUCK TO RUN INTO A STORE. WHEN I TRIED TO START IT I WAS GETTING A MESSAGE TO SHIFT TO PARK. THE ELECTRIC WAS ON, BUT THE TRUCK WOULD NOT START. I CALLED FOR A TOW TRUCK. THE TOW DRIVER GOT THE TRUCK STARTED AND ADVISED ME TO DRIVE IT TO THE DEALER LESS THAN 1 MILE AWAY. WHILE DRIVING ON A MAJOR ROAD I LOST MY POWER STEERING AND STABILTRAK, MAKING IT FEEL LIKE I LOST MY BRAKES. MY EXPERIENCE AT THE DEALER WAS HORRIBLE. THEY CHANGED MY BATTERY AND SAID THEY FIXED THE PROBLEM. I DID NOT EVEN MAKE IT 24 HOURS BEFORE HAVING THE SAME PROBLEM. THE ELECTRIC WAS ON BUT THE TRUCK WAS NOT RUNNING. I WAS GETTING A MESSAGE TO SHIFT TO PARK. THE TRUCK WAS OFF AND PARKED BUT THE DASHBOARD WAS SHOWING D THEN P AGAIN. I CALLED FOR ANOTHER TOW, AND THIS TIME IT WAS ACTUALLY TOWED. THIS TIME I WAS TOLD IT HAD TO DO WITH THE COMPUTER. SERVICE FIXED IT AND HELD ONTO THE TRUCK FOR A FEW DAYS TO MAKE SURE IT CONTINUED WORKING WITHOUT PROBLEMS. 6 DAYS LATER THEY CALLED ME TO PICK IT UP AND IT DIDN'T EVEN MAKE 5 HOURS THIS TIME. THE TRUCK WAS STILL RUNNING THIS TIME, BUT THE ELECTRIC WAS GOING CRAZY. EVERY LIGHT WAS LIT ON THE DASHBOARD. AS I WAS DRIVING IT TO THE DEALER, THE SPEEDOMETER WAS GOING CRAZY. I WAS DRIVING STEADY AT AROUND 35 MPH AND THE SPEEDOMETER WAS SHOWING 1, 0, 5, 0, 30, 31, 6, 0, 5, 31, 32, 1, 0, 5, 0. (I HAVE A VIDEO OF THIS BUT CANNOT ATTACH IT).SO THAT WAS 55 DAYS AGO AND I STILL DO NOT HAVE MY TRUCK BACK BECAUSE GM IS SUPPOSEDLY BUYING IT BACK. I HAVE CONCERNS SEEING 4 OTHER PEOPLE ON THIS FORUM ALONE WITH THE SAME PROBLEM.

THE HEADLIGHTS ARE NOT BRIGHT ENOUGH TO SAFELY DRIVE THE VEHICLE AT NIGHT ON LOW BEAM, AND THE HIGH BEAM MAKES VERY LITTLE DIFFERENCE. IT IS WORSE WHEN THE ROADS ARE WET. WHEN YOU PUT THE HIGH BEAMS ON, THE LIGHTS DO NOT SEEM TO GET ANY BRIGHTER. I HAVE TAKEN IT TO A GMC DEALER TWICE AND WAS TOLD THE HEADLIGHTS ARE WORKING THE WAY THEY ARE SUPPOSED TO WORK. IF THAT IS THE CASE, IT IS A POOR DESIGN AND NEEDS TO BE CORRECTED. THIS HAS BEEN AN ONGOING PROBLEM SINCE WE PURCHASED THE VEHICLE NEW,

I TURNED THE CAR OFF AND IT DISPLAYS A MESSAGE 'SHIFT TO PARK,' EVEN THOUGH THE CAR IS IN PARK. IT DOESN'T ALLOW THE CAR TO SHUT OFF COMPLETELY. THE ENGINE TURNS OFF, BUT THE ELECTRICAL STAYS ON. WHEN WE TRY TO DRIVE IT, IT IS SLOW TO ACCELERATE AND THE RPMS SHOOT TO 4 AND DON'T GO DOWN UNLESS BREAKING. FINALLY THE CAR WILL NOT ACCELERATE PAST 55MPH AND THE RPMS STAY AT 4, WITH THE ENGINE BEING VERY NOISY. THIS LEFT US STRANDED AN HOUR FROM OUR HOUSE BECAUSE THE VEHICLE IS NOT SAFE TO DRIVE. FORTUNATELY THIS OCCURRED IN A PARKING LOT. WE DROVE A FEW MILES TO TRY TO GET TO OUR DEALERSHIP, BUT DID NOT FEEL SAFE DRIVING.

WE BOUGHT OUR 2019 ACADIA WITH 4 MILES ON IT. JUST LAST WEEKEND, THE FUEL GAUGE STARTED KEEPING AN INACCURATE ACCOUNT OF OUR FUEL LEVEL INCLUDING MAKING THE LOW FUEL BEEPING TO HAPPEN WHILE DRIVING. WE PULLED OVER, RESTARTED THE CAR, AND WE WERE BACK TO HALF A TANK. WHEN I FUELED UP TODAY, THE GAUGE WILL NOT GO ALL THE WAY OVER TO FULL AND KEEPS SENDING THE ERROR MESSAGES/BEEPS. IT ONLY HAS 23,770 MILES ON IT. WE'VE NEVER LET IT RUN OUT OF FUEL EITHER. THE DEALERSHIP SAID THERE'S NOT A RECALL ON IT SO I WANTED TO LET OUR PROBLEM BY KNOWN!

SHIFT TO PARK IS HAPPENING ON THE 2019. WHEN IN PARK, ITS NOT BEING SENSED. KEEPS SAYING SHIFT TO PARK. TOOK VEHICLE IN THEY SAID 1/2 A DAY ON 11/22. TURNS OUT THEY NEED LONGER FOR PART. THEY GAVE LOANER, TODAY IS 12/4/19, STILL DON'T HAVE CAR BACK YET. ALSO, BACK WINDSHIELD WIPER MAKING A CLICKING SOUND.

WHEN I TRY AND TURN THE CAR OFF IT HAS AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK". THE CAR IS ALREADY IN PARK AND MESSAGE STILL. NEED TO DO A IGNITION CYCLE TO REMOVE THE CONDITION AND BE ABLE TO TURN IT OFF. THIS CONDITION HAPPENED RANDOMLY, STILL OCCURRING ONE OR TWICE A WEEK.

WHEN I TRY AND TURN THE CAR OFF IT HAS AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK". IT APPEARS THAT THE CAR IS IN PARK BUT I AM UNABLE TO SHUT THE CAR OFF AND UNABLE TO LOCK THE DOORS.

TL* THE CONTACT OWNS A 2019 GMC ACADIA. WHILE DRIVING AT NIGHT, THE CONTACT STATED THAT THE HEADLIGHTS WERE BARELY VISIBLE BECAUSE THEY WERE BLACKED OUT. THE VEHICLE WAS TAKEN TO KEN NELSON AUTO GROUP (1100 N GALENA AVE, DIXON, IL 61021, (815) 288-4455) WHERE IT WAS DETERMINED THAT THE HEADLIGHTS WOULD NOT PROJECT TOO FAR. THE CONTACT ATTEMPTED TO CALL THE MANUFACTURER, BUT THE CALL DROPPED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN.

THE MANUAL GEAR SHIFTER CONTROLS IN LOW GEAR ON THE CENTER CONSOLE DO NOT SHIFT. THE MANUAL CONTROL WORKED DURING THE TEST DRIVE AT THE DEALERSHIP WHEN THE CAR HAD 17 MILES ON IT, MARCH 10, 2019. THE SHIFTER FAILURE WAS FIRST NOTICED WHEN THE CAR HAD ABOUT 500 MILES ON IT, COMING DOWN A MOUNTAIN ON A HIGHWAY WHEN WE TRIED TO USE THE ENGINE TO BRAKE INSTEAD OF USING THE FOOT BRAKE ON MARCH 30, 2019. IN BETWEEN THOSE TWO DATES ON MARCH 21, 2019, THE CAR HAD A WATER LEAK AFTER IT RAINED THAT DRIPPED INTO THE CABIN OF THE CAR AND DIRECTLY ONTO THE SHIFTER AND OTHER ELECTRONIC CONTROLS. I BELIEVE THE GEAR SHIFTER FAILURE IS A DIRECT RESULT OF WATER DRIPPING ONTO THE SHIFTER AND OTHER ELECTRONICS ON THE CENTER CONSOLE. I HAVE 3 DOCUMENTED SERVICE RECORDS ATTEMPTING TO REPAIR THE WATER LEAK AFTER 3 SEPARATE RAINSTORMS THAT WAS ULTIMATELY DETERMINED BY GM ENGINEERING TO BE A MANUFACTURER DEFECT. WHEN THE GLASS IS POSITIONED FOR THE REAR MOONROOF, THE POSITIONER IS SUPPOSED TO HOLD THE GLASS IN PLACE FOR A MOMENT TO SEAL. INSTEAD THE POSITIONER MOVES CREATING AN AIR POCKET. THIS RESULTS IN WATER INTRUSION INTO THE CEILING OF THE VEHICLE AFTER RAIN, WHICH THEN SEEPS INTO THE FABRIC LINER AND DRIPS DIRECTLY ONTO THE CONTROLS. I AM WORRIED ABOUT WHERE ELSE WATER HAS TRAVELLED WITHIN THE CAR, KNOWING IT WAS MANUFACTURED IN JULY 2018 AND STORED OUTSIDE MOST OF ITS LIFE. THE SHIFTER IS THE FIRST OF WHAT I FORESEE AS MANY ELECTRICAL ISSUES THAT CAN ENSUE WITH WATER INTRUSION, AS IT HAS OCCURRED IN A CAR HAVING UNDER 900 MILES ON IT. WITH ALL ELECTRONIC TRANSMISSION CONTROLS, I AM WORRIED THAT IF WATER DAMAGED THE LOW GEAR SHIFTING, THERE COULD BE FUTURE AND MORE DETRIMENTAL TRANSMISSION MALFUNCTIONS (POSSIBLY CATASTROPHIC). BEYOND ELECTRICAL FAILURES, MOLD IS A WORRY IN THE HEADLINER AND CARPETS CREATING A HEALTH HAZARD IN MY VEHICLE WHERE I TRANSPORT MY TWO SMALL CHILDREN.

THE SECOND ROW CENTER SEATBELT WILL NOT RETRACT.

MY MOTHER HAS BECOME TRAPPED TWO TIMES DUE TO THE LOCKS ON THE VEHICLE NOT WORKING. THE ISSUE ONLY HAPPENS WHEN IT RAINS. I TOOK THE VEHICLE TO THE DEALERSHIP AND THEY SAID THEY REPLACED SOME KIND MECHANISM AND THAT EVERYTHING WAS GOOD TO GO. IT RAINED AGAIN YESTERDAY AND MY MOTHER WAS TRAPPED IN THE VEHICLE AGAIN. THIS HAPPENS ANYTIME YOU TRY TO ENGAGE THE LOCKS, I.E. IN PARK, PUTTING IT IN PARK, PUTTING IT IN DRIVE, USING ONSTAR TO LOCK OR UNLOCK, USING THE GMC APP TO LOCK OR UNLOCK, USING EITHER KEY FOB TO LOCK OR UNLOCK, TRYING TO LOCK OR UNLOCK IT MANUALLY.

HEADLIGHTS ARE NOT BRIGHT ENOUGH TO SAFELY DRIVE AT NIGHT, INCLUDING WHEN THE HIGH BEAMS ARE ON.
