2024 GMC Canyon Problems & Complaints

I first noticed the brakes squealing in August 2025 at 15,000 miles. The dealership said I needed to resurface the front rotors. I mistook this a coating and brake debris, but it was actually the rotors warping. By 21,000 the vehicle is pulsing heavily when stopping. I went back to the dealer and this time they told me all 4 rotors are warped. GM denied coverage of the pads and rotors. Normal driving, no collisions or towing.

Coolant leak caused by known manufacture defect in upper hose assembly causes coolant to drain and engine to overheat. CEL only comes on when coolant is almost gone. GMC refuses to cover the known issue after 36k miles.

Coolant Leaking at 22K miles, smell of coolant, check engine light on and off 2X's. Coolant evidence on driveway and in engine cabin. Known condition for GM Model. No parts available for replacement. No recall for issue.

Radiator Hose began to leak coolant. Faulty radiator hose. This could have caused engine failure and potentially caused an accident or may have put others at risk for hazards. No warning other strange sound. Inspected by authorized dealers service center.

Upper radiator hose connection to radiator is faulty causing leak of coolant. Yes it is available for inspection upon request. Truck began to run cooling fan at full speed in the middle of winter with no warnings of high heat or low coolant. After two weeks, check engine light finally cut on to indicate low coolant flow. Coolant reservoir was subsequently checked and found to be completely empty. It is apparent this reservoir had been extremely low / empty for at least two weeks with no warnings. Without proper warning and leaking coolant, truck could have overheated. Should this had happened in dead of summer, truck could have very well overheated with no warning. The problem was investigated and confirmed by dealer as leaking coolant at the connection of the upper radiator hose to the radiator. Was quoted $983 to replace the hose. No warning lights appeared until issue had been ongoing for over two weeks. A quick search of "GMC Canyon Upper Radiator Hose" will reveal many identical occurrences of this issue. This is a safety hazard / design flaw that GM is not acknowledging and is putting the burden on the vehicle owners for their own issue.

On 2 occasions the battery was drained and a tow truck had to jump the battery. On one occasion after the battery was jump started it took several hours before the brakes were able to be used and the car driven safely. Had to drive very slowly (under 50 mph) per note that appeared on dashboard. After nearly an hour of waiting Engine light stayed on and dealership ran diagnostic and found nothing wrong with the battery nor anything else. Have to start and run engine everyday to keep battery from dying. If not started in 24 to 36 hours, battery will die.

Upon starting the vehicle, I got multiple warning lights. The most important was brake failure. I had no brake function. I took it to the dealer and they replaced the brake module after 3 days.

There are widespread reports of the O ring seals on the radiator and heater hoses failing and causing coolant leaks. These leaks are significant enough to render the vehicle inoperable and with no cabin heating or cooling. This could lead to life-threatening situations in adverse weather conditions. It could also create dangerous roadside failure situation in heavy traffic, particularly on interstate highways. Dealers are aware of the issue and are currently repairing vehicles under warranty. However some dealers are telling owners that the cooling system is not part of the engine and drivetrain, and therefor is not covered under the original factory warranty if the vehicle has exceeded the initial bumper to bumper warranty limits. Dealers are also telling owners that parts are on backorder due to high demand, and that repair wait times could take weeks. The vehicle is unsafe to operate with a known coolant leak.

Upper radiator hose attachment is leaking due to faulty rubber gasket. This comes up across GMC Canyon groups on Facebook 10 times a day. It is happening to ALL of them mainly pre 2025 on 3rd gens. Part is on back order at all GMC dealers due to so much volume of issue. Happening as early as 10k-20k miles on brand new trucks causing over heating issues due to coolant leaking out. Hopefully a recall for the part is done before engines start blowing.

Truck began idling very rough. Went straight to the dealership. They shut the truck off and it would not restart. No CEL or messages on the dash. Tear down reveled a failed exhaust valve in cylinder #4. Truck has 10,000 miles. A replacement engine has been ordered under warranty. Luckily, we happened to only be a few miles from a dealership when the failure happened. There was no warning, no prior symptoms what so ever.

The contact owns a 2024 GMC Canyon equipped with Goodyear Tires, Tire Line: Wrangler Territory, Tire Size: 265/65/R18, DOT number: 1M6C8JT1R. The contact stated that while her husband was driving at an undisclosed speed, the TPMS indicated a low tire pressure. The driver pulled over and noticed that the passenger’s side rear tire was low. The vehicle was taken to a tire shop, and it was determined that the tire damaged and the lock was missing. The mechanic located a pair of pliers between the rim and tire. The tire was replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The tire and vehicle failure mileages were unknown.

Upper radiator hose leaks where it connects to radiator. 40k miles and my truck has no coolant

I am reporting a driver distraction safety issue involving the infotainment system in my 2024 GMC Canyon. The vehicle displays a mandatory “Focus your attention on driving” warning every time the vehicle is started, requiring user acknowledgment. When using the built-in Google Maps navigation without subscribing to GM’s paid Connected Services plan (while tethering to a personal cellphone hotspot instead), the system displays a modal warning stating that a connected services subscription is required. This warning appears whenever cellular connectivity is briefly interrupted, even for a few seconds (such as when driving through a known cellular dead spot). The warning overlays the navigation screen and requires the driver to manually press a “Dismiss” button to continue, even while the vehicle is in motion, requiring the driver to take their eyes off the road to focus on pressing the dismiss button. This behavior creates a safety contradiction: The system warns drivers to focus on driving, then forces manual interaction with the touchscreen during active driving. The interruption is triggered by transient network conditions, not driver action. The behavior does not occur if the driver pays for GM’s subscription service, indicating it is a business-rule enforcement rather than a technical or safety requirement. The repeated appearance of this warning during normal driving conditions constitutes an unnecessary and avoidable distraction. It diverts attention from the road and navigation, increasing risk rather than reducing it. I believe this design violates established human-factors safety principles by introducing nonessential driver interaction during vehicle operation and should be reviewed as a potential safety defect related to driver distraction. We just got home from a trip to West Texas and had to press the dismiss button no less than 100 times while driving through areas with marginal/intermittent cell service. It's a huge driver distraction.

I've noticed an issue since I picked up my vehicle from its last service where the RPMs stay around 1,000 when I let off the gas and should be coasting. The vehicle will continue to accelerate at 11 to 13 mph, and I really have to mash the brake pedal to stop. There is an update notice that popped up starting yesterday, but it will not install. Looks like the update is for the issue I am having. The update was supposed to be installed already per the service bulletin. Update number is N242452130

The contact owns a 2024 GMC Canyon. The contact stated that while driving at various speeds, the steering wheel was rattling abnormally. The check engine warning light was briefly illuminated. The vehicle was taken to a local dealer, where the vehicle was test-driven; however, the failure was not identified. The failure reoccurred, and the vehicle was taken back to the same local dealer, where it was diagnosed as needing a rear intermediate steering shaft, and a retest was performed. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer, where the vehicle remained under investigation. The manufacturer was made aware of the failure. The failure mileage was approximately 4,491.

2024 GMC Canyon Elevation trim 4x4 with 31,000 miles on it always had maintenance every 5k interval. I noticed an upper radiator hose leak significant enough to require a decent amount of coolant and decided to take it in to GMC to get it repaired. Mind you this repair is almost $1,000 to get repaired with the hose itself only costing $148. It's disappointing to have such a new truck and have these kinds of problems and upon research there seems to be several others with the same problem relating to an O ring in the upper radiator hose. Considering the truck is routinely serviced more frequently than required I see this as an issue for someone to run out of coolant and possibly be stranded on the side of the road if gone unnoticed and needs to be properly addressed asap.

16,000 miles driven and my replace brake sensor light came on the dashboard. I took it in to get looked at and was told the Front Drivers Side has 1 brake pad showing a life of 5 while my other pads all showed a life of 9/10. I was told that most likely something stuck inside the brake pad itself causing it to wear unevenly but I don't drive anything but highway and paved roads. I looked around other forums and multiple others are complaining of the same issue. I contacted GM and they told me brakes are a wear item. The dealer told me they aren't sure how it happened, but this isn't right to be replacing brakes on a brand new vehicle I've only driven for 10 months. Multiple others are saying the same thing in GM/Colorado forums.

Break monitors for front breaks have dislodged and caused damage to rotors and pads. Dealer claims this is normal wear! Breaks shimmy when breaking in all directions and squeak when backing. I travel to my work requiring mountain passes during inclement weather. The most important safety method while traveling on snow and ice is smooth steering, acceleration and breaking. With my font breaks shimmying, I am concerned for my safe control of the vehicle. Thank you in advance for your attention to this matter.

Infotainment system audio not working. Have performed hard reset, dealer reset, dealer service, and still audio is intermintant at best. more than 75% of the time I have no audio or sound at all. No raidio, no sxm, no bluetooth, no onstar. This is a safety issue and there does not appear to be a repair bulletin, and dealships dont know what to do.

The contact owns a 2024 GMC Canyon. The contact stated that on several occasions while driving at an undisclosed speed under sunny conditions, light entering through the windshield reflected off the chrome trim around the instrument panel and caused distortion and lines in the driver's side and driver’s mirror, creating a visibility hazard. The contact added that the glare disappeared when the windows were rolled down. The vehicle was taken to a dealer, and the contact was informed that the vehicle was operating normally. The manufacturer was notified of the failure. The failure mileage was 12,604.

Vehicle brakes stopped working while driving. Dash board lit up and stated system brake failure. Also stated “do not exceed 43mph”

The contact owns a 2024 GMC Canyon. While the contact’s son was driving approximately 35 MPH, the brake pedal was depressed; however, the vehicle failed to slow for a traffic signal and the brake pedal was stiff. The contact stated that his son needed to use force to depress the brake pedal. There were several unknown warning lights on the instrument cluster. The contact stated that the phone app showed a failure with the ABS. The contact stated that the failure was intermittent. The vehicle was taken to a local dealer. The dealer was not able to duplicate the failure and cleared the codes from the warning lights but provided no information on the fault codes. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 11,000.

The Driver Information Center located directly in front of the driver that contains the speedometer, tachometer, oil pressure...etc., has a very distracting background. The background is a geometric patterns of triangles giving a sense of depth. This is very distracting especially at night. Quick looks to see speed, engine temperature or other critical vehicle information is complicated by this unnecessary aesthetic background. I reported this problem and it can be located here: [XXX] I've been advised to mail via USPS my concern to The Office of Defect Investigation Team which I will do today.

Propulsion of vehicle. Truck lost power as I was trying to pull into traffic at an intersection. Yes, it was confirmed by the dealer; truck was returned after 3 incidents. GM has been inspected the truck. Yes: check engine light immediately came on, and a comment then stated onscreen: "caution. Your vehicle has lost power and is operating at a reduced capacity". First occasion, truck was approx 6 months old. Second was 1 month later. Third and dangerous incident occurred June 11th 2025. Dealer keeps saying the truck is OK. Failure to propel keeps happening. Service supervisor tells me truck needs a new module, but GM won't approve it. Truck is still at the dealer, and issue has been escalated twice. Truck still at dealer.

The vehicle does not have a manual switch for the headlight control. The only way to control the headlights is through the digital control interface on the infotainment console panel. The headlight controller button is so small that a person has to take their eyes off the road for a long time making it a very unsafe condition. If a deer was in your lane you could not turn your lights on and off quick enough to maybe un shine the deer so in would move while honking your horn. It is just totally unsafe as a hole when you’re not looking down the road while driving. If you had the switch you can always feel around for it much safer than taking your eys off the road while driving.

While driving a two lane road the adaptive cruise control detects oncoming traffic and improperly slows down or breaks unnecessarily. Most of the time the vehicle breaks so hard it will jolts me forward in my seat. I fear another car will be behind me and this will cause an accident. I have had my vehicle in the shop two (2) times to repair the issue. The dealership/service department has been able to replicate the issue by having one of their technicians drive the vehicle. The front camera has been replaced twice and I have been told every time they plug a new camera in the trucks interior and exterior lights "go crazy and flash". GM's response to this issue is "set the gap to mid" or simply "shut it off". They refuse to see this as an issue. Doing my research I found that the 2023 GMC Canyons have been recalled due to the same issue. I have brought this information to the sales department. However due to not being able to find this on General Motors website I have been told by the dealership/service department, and owner of the dealership that the information I found on NHTSA is insufficient and they can not go off this information.

When turning right, the turn signal overcancels, causing the left turn signal to come on.

Rack and Pinion assembly failure. Steering became “sticky”. Had to pull on the wheel to break it loose multiple times to make a full turn. This occurred while driving on the highway. No warning or lights. Confirmed by dealership. Truck has 2200 miles, under warranty. When I took the truck in they also informed me there was a recall on the fuel injection computer. I found that strange considering I was never alerted of this recall nor can I find it anywhere online with my vin number.

The chrome trim that is on the dashboard has a glare that reflects into the rear-view outside mirrors making hard to see obstructions the problem is all weather conditions sunny or cloudy

We were traveling not once, but twice at a high rate of speed (75/80mph the legal limit) the vehicle gave one message: Service power steering next message: reduced acceleration. The check engine light turned on, the truck itself jerked and we almost lost control of the vehicle (both times) on the highway. We were thankfully able to pull over and pull to a complete stop. The vehicle was still on, it still ran but I saw an autozone close by both times and received a code for the check engine light. The dashboard both times lit up like a Christmas tree on both occasions before spazzing out. We have taken the truck twice to a nearby dealership and they were able to service and “fix” the problem however they said that the first time, and here we are a second time. The dealerships we took the truck to are aware of all the codes (2 pages worth the first time) but we never received paperwork on what was fixed. The second time we are now going to pick up and hopefully receive paperwork on what was completed. My spouse was driving and myself and my daughter were in the vehicle when the jerking happened with the steering wheel. The vehicle is not safe how can I we be driving at the legal limit and lose control of our vehicle. We were right next to an 18 wheeler with a trailer and multiple vehicles on the road each time. The GMC dealerships are aware they have been working to fix the problem however again this is the second time it happened. The messages occurred both times. Service power steering and reduced acceleration check engine light and also no traction control. The first time it happened was [XXX] going to Killeen Texas and the second was [XXX] going to Albuquerque. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Trailer braking and stability control randomly disables. This leaves an unsafe condition when towing any trailers that require a trailer brake controller. Has happened on multiple occasions.

Heat shield over drive train not installed properly. While driving since purchased I’d hear a metal reverberation / clunking sound that seemed to be under the truck. I even had it in for oil change service w/ dealer and no mention of finding anything. On Sat 3/15/2025 I took it back to dealer with the heat shield that was torn from the undercarriage over the drive train, the service person said it did not to appear to have been fastened at the factory before delivery to dealer/me. They were going to re-install it, however it was damaged; and I told them that was not acceptable to put a broken part back on the truck. I still don’t know what other damage has occurred to the vehicle due to the rubbing/clanking around while driving the 12,000 miles I have on it. They told me it was safe to drive and just come back when they get the part in. I have photos and videos; the dealer took the damaged heat shield from me and I don’t know what they did with it. Risk level to other drivers is the heat shield could have flown off truck while driving; to me inside the vehicle could have obstructed drive train and caused damage/accident, and other damage I’m still not aware of. Yes, dealer advised: Harnish GMC Puyallup, WA 253-840-6300 No fix yet. No warnings in vehicle or on any electronic displays. I noticed the sound right away on purchase but couldn’t identify it until it “got so bad” I went under the truck to look, and found it separated and dragging on the drive train.

The dealer did not fix the recall item on my truck as posted here. The dealers service department confirmed with me on multiple occasions that the recall was not fixed as annotated, but since the dealer was paid for the recall (because it was posted to the system) I am still on a waiting list for them to coordinate how to do the recall work (that was already paid for, what?). I would just like the recall work to be completed on my truck and the notification corrected on your database that the work was not done when input, editing to correct the date of service

Collision Avoidance comprised of Following Gap and Alarm / Auto Braking does not function. One dealer after two trips and unable to repair stated that GM is working on a new software update and until that is available repair is not possible. No date was provided by dealer or GM customer service as to when this update would be available. Second dealer stated that system was in fact not functioning, and asked me to return in a couple days, so he could research the issue, He knew nothing about a pending update. Both dealers stated that no alarms or codes were present in spite of failure.

While driving on the highway, the sunroof of the truck shattered. There were no other vehicles nearby at this time. No one was hurt and nothing hit the vehicle to cause the sunroof to shatter. The vehicle was brought to the dealer for inspection/repair. This incident occurred on 3/4/2025. There was no rain or snow occurring at the time and temp outdoors was around 40 degrees. In addition to this incident, a piece of trim came loose on the vehicle that was repaired. No injuries resulted in this as it was noticed before it came off and hit anything going down the road at a higher speed.

The contact owns a 2024 GMC Canyon. The contact stated that while washing the vehicle, it was discovered that the exterior roof panel was bent and caved inward. The vehicle was taken to the local dealer who informed the contact that the vehicle was manufactured without the roof braces which were needed to strengthen the roof. The braces were ordered by the dealer. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 4,000.

Vehicle whole system was non existent. No interior lighting, no door chime when opened, no response. Mechanic took a look and found alternator not good. It’s not charging the battery and advised me to tow it to warranty repair shop. Advised me if I were driving and vehicle died I would not have power or control of vehicle and cause serious injury or death. Lucky I was parked at home and attempted to start vehicle to leave home. No repairs done yet, vehicle is still at home waiting for an appointment.

On [XXX] I took a trip with family through Ohio from Pennsylvania. While truck was in adaptive cruise control on highway, phantom braking occurred where truck slowed down from 70mph to about 60mph 5 times. No objects or vehicles in front of truck or around truck during the braking. The weather was mostly clear overcast at times with no rain or snow. Concerned if vehicles were behind me during the breaking causing an accident. It was abrupt completely out of the blue when it happened. Took truck into service on 1/8/25 for oil change and braking issue, dealership states there’s no service bulletin for issue. I have not used adaptive cruise control since.

While driving through a car wash air blow dryer, the roof was popping in and out resulting in a dent of the sheet metal. The roof area appears to be very weak structurally. The roof can be pushed in by hand. This could be dangerous in a rollover situation.

Battery dies during vehicle update spontanteniouly. After jumoing vehicle to start it all systems will not return to normal causing brakes not to function normally. I jumped my vehicle after one system update and brakes failed to engage almost causing an acident. these vehicles should not be on the road due to the software safety flaws. GMC is aware of this and still have no fix for the problem. There are numerous accounts of this happening to this vehicle on forums and solcial media.

While addressing the Headlamp Flicker recall N242468880 another problem was caused. The Drivers side headlamp is always on high-beam There is no way to turn it off. I have had two incidents where oncoming traffic has crossed the double yellow line. The dealer states that the entire headlight mist be replaced and it is on backorder with no expected date of availability. This 2024 GMC Canyon is blinding oncoming traffic and is a risk to myself, my passengers, and oncoming traffic. I have a case open with GM and it has accomplished nothing. GM case number 9-14098737984

When the right turn signal cancels after completing a right turn, the left turn signal activates, flashing 3 times. This appears to be the result of a defective design with the turn signal level. The dealer has acknowledged the problem and has stated that there is a bulletin from GM from several months ago which does not provide any resolution to the issue. This is a safety issue since the turn signals are not operating correctly, which could confuse other drivers.

When the right hand turn signal is cancelled following a right hand turn, the left turn signal flashes to indicate a lane change. This would falsely indicate intention of changing lanes.

The back seat is not secured tightly. When the bottom seat is down, and should be locked, there is 3-4 inches of play when lifting up on the bottom seat. It does not seem to lock properly. I told the dealership about it, and they compared it to another vehicle on the lot that did the same thing. They did not seem concerned, but if a latch is defective, anyone in the backseat could be harmed if the latch fails during an emergency stop or accident.

Where to begin... As I bought my first truck, literally within 10 days after buying the GMC Canyon 2024, the car is shaking uncontrollably on the highway... 35 MPH max speed, extremely dangerous situation, 8 AM on a busy Watterson Expressway in Louisville, KY. I was so scared I was going to crash and potentially get hurt or worse. They told me "they had never seen this happen to a Canyon before" which is obviously a lie. The car was serviced for 21 calendar days, and now my lights are spotty and I can't drive my car at night. I got this truck [XXX]. There was no communication on when it was to be ready. There are issues with a lot of minor things as well like the navigation systems. I have logged every call with the Dealership, Courtesy Buick GMC in Louisville as well as summarized every point of contact, and with very spotty responses and the manager, Frank, wont respond to my emails and was extremely uncooperative as I asked to trade it in as I was genuinely concerned about my safety and he told me absolutely not.

Turn signal not working properly and GM has not issued a solution to dealerships. Issue: When you use your turn signal to change lanes or turn onto a new street, the turn signal will flash to let drivers know. However, when you turn off your turn signal manually or the truck turns off the turn signal automatically when you turn the corner, instead of the turn signal stopping, it starts flash in the opposite direction by itself and eventually stops. This can be confusing for drivers and could result in an accident if someone thinks you are signalling and then go in a different direction.

i have had this truck 3 months and already had software problems and now I had to drive to Hammond LA after dark and the headlights were blinking, going up and down. I was passing an 18 wheeler and the light beam went up and i almost went under the 18 wheeler. God was with me for sure.. i have not received any info on the recall and went by the dealership where I bought it and they sAid I would have to wait until I get a notice in the mail. so now I cannot drive at night and I need to. what is a person suppose to do?

When I make a right turn, after completing it, my left turn signal flashes three times. This is very confusing to other drivers around me and I’m concerned could cause an accident. This has been occurring since I purchased the vehicle. The dealership advised that the headlight flicker repair would likely fix it, but it did not.

The contact owns a 2024 GMC Canyon. The contact stated that while driving at an undisclosed speed at night, he observed the headlights flickering. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V673000 (Exterior Lighting); but the vehicle had already been repaired. The manufacturer was not notified of the failure. The failure mileage was 5,000.

Headlights blinking on and off all the time. supposedly parts or on back order with no time line.

Vehicle was brought in 5/18/24 for check engine light Dealer eventually found broken wire in headliner on right side Dealer repaired wire and I picked up vehicle 5/22/24. Vehicle was brought in 7/29/24 for park assist code dealer found short in wire. Dealer stated that to fix wire would require taking cab and bed off frame. Dealer ran a new wire along frame to avoid fixing properly. Vehicle picked up 8/1/24. Vehicle brought in 9/10/24 for a variety of sensors activated. Dealer stated to me that anti-lock brake module was on NATIONAL back order and not expected until 10/28/24. Ut was not safe to drive the vehicle, and they have had the vehicle from 9/10/24. Also, drivers power window module has to be replaced. This 2024 Canyon has been a problem. I have contacted GM and asked for a buyback of the vehicle which GM refused

Headlights flicker on and off

The contact owns a 2024 GMC Canyon. The contact stated that while driving at undisclosed speeds, the headlights were flickering. There were no warning lights illuminated. The contact received notification of NHTSA Campaign Number: 24V673000 (Exterior Lighting); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was approximately 100. Parts distribution disconnect.

The turn signal is activating in the opposite direction. After completing a 90 degree right hand turn, when the turn signal deactivates it will turn on the left turn indicator for 3-5 seconds. This only happens when making right hand turns and I have been able to replicate it on multiple occasions. My concern is that other people will see the indicator and assume that I intend to change lanes when my intention is to continue straightforward. This could cause someone to move in front of me or turn into my lane of travel. I just purchased the vehicle a week and a half ago. I plan on making an appointment with the dealership within the next week to have the issue evaluated. This was first noticed about 1 week after taking ownership. I purchased the vehicle on September 13, and noticed the issue on September 20.

Front head light flickering

Headlight Flicker when they are on

Adaptive Cruise Control has applied brakes multiple times while cruise has been sent at speeds ranging from 55-75 MPH. Vehicle aggressively slowed down 10-20 MPH then picked up speed. No vehicles in sight ahead of vehicle, aggressively applied braking without warning. Aggressive braking could cause traffic behind vehicle to crash into me while driving at high speeds. Multiple other reports of this happening to other 2023-2024 GMC Canyon owners based on comments on Facebook and Reddit with acknowledgement from the manufacturer that this is a know issue they currently are trying to resolve. Issue not isolated to this vehicle. Vehicle has not been inspected by Manufacturer or problem been reproduced dealership. Vehicle goes in for service next week, meanwhile cruise is not being used as it is a safety hazard. No collision warning or any other warnings experienced with this issue. Issue first happened on day 1 of vehicle ownership and has happened 2-3 other times with one instance of it braking and accelerating 3 times over a 2-3 mile stretch of highway with cruise set at 75MPH with vehicle slowing down to around 55MPH before resuming set speed.

Headlights flick intermittently

The vehicle, since it's purchase, has a persistant flickering occuring with the entire headlight when the main headlights are on. The problem doesn't seem to be an issue when the DRLs are only being used. The vehicle was taken back to the dealership to be looked at but when they discussed the issue with the GM even they couldn't figure it out. This can pose a serious safety issue if the lights go out all together at night on a dark roadway.

HEAD LIGHTS FLASH 2-3 Times a minute and getting worst safety concern others driver pulling over thinking I'm the police, had a truck pull out in fount om me assuming i was flashing him to come out, came close to losing my life ,I'm afraid it going to cause road rage called dealer three day after purchase drop it off they inspected and called gm known issue doc #PIT6203A ,no current fix for issue i was told to keep paper in truck in case i get pulled over by police for flashing light s hopefully you wont get ticket the date 8- 19-2024

Headlights flicker every few minutes when on. Can be distracting to driver and other cars on the road at night. Seems to be an issue for several people with these new 2024 trucks but GM has no fix yet.

Headlights flicker about once every minute. it gives the impression that i am using my brights for oncoming traffic and has caused other drivers to "flash" their brights at me and i get flashed after passing other vehicles. I am concerned that at one point the "flicker" will just shut off and leave me totally in the dark driving country roads. i drive mostly on rural highways. it would be impossible to drive without lights. Also the flicker is causing other drivers to potentially "road rage". I took this to the dealer last month. GM has not come up with a fix and has told the dealer not to do anything at this time. problem has occurred since deliver in early June

Lights flicker at random times

Safety Issue: Headlights and running lights flicker off and on every 1-2 minutes.

Headlights are flickering with no available fix to the issue.

Headlights flicker constantly. While being extremely distracting and unsafe while driving, it also causes other driver to think I’m flashing them. This leads them to flashing their high beams at me when oncoming and pulling over to let me pass when in front of me. Also, after I complete a right turn, my left signal flashes 3-4 times. I brought it to the dealership and they said they suspect a “software glitch” but that GM hasn’t determined a cause or solution yet. It appears to affect models built in May/June 2024 and on. I was also told that the display screen in the truck can be/may become affected, which is the only way to control the lights in the vehicle. They could not provide me with a loaner or replacement and said to keep driving the vehicle as-is until GM can come up with a fix, despite repeatedly agreeing with how unsafe it is. I have filed a report with GM as well. I was told to “make noise and maybe they’d get it fixed sooner.”

Headlights flickering while driving. And it is quite noticable and distracting to other drivers. I feel this could cause accidents. I have been flashed by upcoming drivers due to them thinking I turned on my bright lights. And this is constant at 2 to 5 minute intervals. The dealer can't fix cause GMC doesn't know how to fix. And neither GMC or the dealer is going to contact me when there is a fix. The dealer said call every 2 weeks and they will check on line for any updates for the problem.

Headlights intermittently flicker when on sitting still or driving. This happens from a couple of times a minute, up to 5 or 8 times a minute. Other drivers are flashing their high beams at me because of this flaw. I can see a road rage incident occurring because of the issue.

The Headlights flicker, mostly noticeable at night. They do not remain a steady beam of illumination. This is a major distraction and noticeable by other drivers as well as I have been asked not so kindly by another driver, why I keep flashing my lights at them. I have had this vehicle at the dealership for over a month, waiting for a repair. This is a brand new vehicle and should not have this kind of defect in the lighting. I need my vehicle fixed.

I noticed within a day or so of receiving my new 2024 GMC Cayon that the headlights would randomly flicker. No specific pattern or time interval just random. When I was finally able to get the truck in to the dealership for service, they reviewed the issue and called me the following day to inform me that couldn't repair it. Seems that GMC is aware and they currently have no fix since all headlights they have in stock potentially have the same issue. It seems obvious to me that driving at night with headlights that will not stay on is a huge safety issue and needless to say I do not want to cause an accident or get cited for an issue the manufacturer has no repair for. Leaving my only vehicle parked at home till a fix is found is not an option either.

Headlights flicker at night. GM is saying there is no fix and no ETA. It happens periodically when headlights are on. Not a one time issue

Constant headlight flickering. Lights sometimes shut off totally. Almost caused (2) accidents due to this safety issue! Why will the NTSB not make GM file a recall for this issue? Does someone need to be killed first? Do your job and make GM do theirs!

headlights will flicker/flash intermittently. Vehicle will flash beams , vehicles will brake check thinking they are being flashed. Dealers informed that there is no fix at this time no update new vehicle was brought in shop a few weeks after purchase no update on this issue

The headlights and day time running lights flicker intermittently.

Lights flicker intermittently causing a distraction and limiting visibility when driving at night.

My headlights keep flickering immerdiently, it doesn't matter if they are on auto or manually. I called the dealership I purchased it from and they said there is nothing they can do until they receive a resolution from GMC. This poses a safety hazard at night. Not only that, people keep thinking I am flashing my lights at them.

When On, the normal beam headlights randomly flicker off and back on very quickly. This occurs when headlight control is in "Auto" or "Manual On". Its periodicity varies. The flicker is so fast that driver visibility is not impacted much at this time. However, on coming vehicles and vehicle in front of my truck are getting lights flickered at them. This can lead to confusion, annoyance and road rage. The primary impact is getting brights flashed towards me, which does inhibit my vision for a time.

Headlights intermittently flicker. It causes other drivers to focus on my vehicle. It also cause me to focus on the issue more than actually driving the vehicle. It could cause issues with road rage. To my knowledge GM is aware.

The headlights will flicker for a split second every 1-5 minutes, affecting both headlamps. While this issue does not make the car unusable, it is not expected of a brand new vehicle and could be interpreted by other drivers as aggressive signaling that leads to potential road rage escalations.

Vehicle headlights flicker on/ off momentarily at random when travelling at night. The flickering is NOT the automatic high beam function. When flickering occurs vehicles ahead may believe the lights are being flashed at them. GM issued a repair order to replace headlights but has since stopped performing replacement because problem has not been solved.

My GMC Canyon has an issue with flickering of the headlights at night, which sometimes results in one side or the other going completely out. I'm part of several Canyon forums, and this seems to be an issue with most 2024 Canyons. The flicker is more of an annoyance, as I can still see, but I do believe it blinds oncoming drivers when it happens, as they flash me. Obviously headlights going completely out is another issue. I have not had both go out at the same time, but many others have. The flicker happens every time my headlights are on. The total outage has only happened once. I did contact the dealership where I purchased this, and they said this is a known issue with no resolution yet. They sent me TSB #PIT6203, which states there is a known issue with the "issue internal to the LED controller that is part of the headlamp assembly". This TSB initially had a fix of replacing the headlight assemblies, but was updated in July to instruct dealers not to do that, as it doesn't fix the issue.

While driving at night the headlights flicker for some unknown reason. I have seen where many others are having the same issue.

The headlights when turned on flash/flicker from while driving at night. I see they have service bulletin but this is hazard as it temp brights other drivers as well as causing a weird issue while driving.

The headlight assemblies has a random blinking, flashing, flicker, on/off problem. This causes people to think I am either flashing them or blinking my light at them. Major safety concern!! GM is aware of this issue and does not have a fix. I requested a different vehicle to drive until they fix this safety issue and was denied.

Headlights flickering

My headlights flicker. The issue is problematic because other drivers think I'm flashing my lights at them. There are no warnings on the dash the vehicle is brand new. I took it home last friday. It creates a driver distraction and is unsafe. I took the vehicle back to the dealer and they advised a software update was coming. When? My problem is not resolved.

Headlights blinking/flickering every 5 seconds to 45 seconds in between.

The headlights in front of truck are doing a flicker here and there. It is happening by itself, during normal operation. It kind of looks like I'm flashing my high beams when it happens. People may think I'm flashing my high beams at them when I'm not. I think other people are having the same issue with this GMC truck. I have not contacted GM waiting to see if they will publish something, since it seems like they are now aware of the issue?

Headlights flicker often and usually one side at a time, sometimes one side is out for a second or 2. Drivers in front of me think I'm flashing them and get upset, it's annoying to keep seeing it every 1-2 minutes and makes driving at night miserable. Started the night of delivery. Dealer notified and awaiting call back.

headlights flickedr/flash randomly and briefly regardless of if they are manual on/auto on coming traffic thinks i am flashing them GMC Seems to be aware of the issue but no resolution as of yet

Headlights Flicker Randomly. Looked on forums and it seems to be widespread. People think your flashing your lights at them.

The headlights flicker off and on every 30 seconds or so while driving or stationary. This occurs no matter what setting the headlight are in. Other drivers think I am flashing my lights at them and have responded negatively by brake checking me in traffic, flashing their high beams at me when oncoming etc. I am worried that the lights may flicker off and stay off while driving at night. The dealer has recreated the problem but still has no fix. My truck has been in the dealer's shop since mid July.

The issue involves the headlight assemblies flickering frequently. The whole headlight assembly will randomly turn off and on, one at a time typically. It will cause temporary loss of sight down road at night. I have also noticed other motorists flash their brights at me thinking that's what the flicker was, so it's causing disruptions to other drivers as well. GM is aware of the issue but has no fix in place and no timeframe for the fix.

Headlights flash intermittently while driving. I have not reported this to manufacturer since this is a known issue. Wanted to report to ensure vehicle is listed for safety recall/repair when available.

Headlights periodically turn off and on while driving automatically, randomly, and without warning. Causes other drivers to become confused, disoriented, or enraged. Drivers think they are being intentionally flashed or harassed and respond with brake check or moving to another lane and becoming visibly distressed. This is a new truck, with less than 500 miles, and no warning lights are issued.

Headlights flicker repeatedly while driving. About every 1-2 minutes

The contact owns a 2024 GMC Canyon. The contact stated while driving at an undisclosed speed, the front headlights were activated; however, the front headlights failed to operate as intended. The contact stated that the front headlights continuously flickered from high to low. The vehicle was taken to the dealer and the failure was visible and documented. The contact was informed that there was no remedy for the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 225.

Headlights have intermittent lighting failure resulting in brief flashes/blinking of the lights. There are multiple complaints and this is known by GMC, but there is no current resolution.

Bought ‘24 Canyon one week ago. Vehicle headlights flicker a second at a time on their own. Flicker seems to happen once every 1-2 minutes. Flicker can cause confusion with other drivers and ignite road rage.

Headlights flicker approximately every 30 seconds. Creates unsafe driving conditions and is a distraction to other divers. Other drivers assume I am flashing my headlights at them. Dealer has not been able to fix the issue. This occurs whenever the lights are on.

Headlights seem to flicker intermittently while sitting in park and driving.

Headlights flicker (on/off) very rapidly, independent of each other, at random times.

Headlights have an intermittent flicker that happens every 2 to 3 minutes. This flicker is a complete shutdown of the headlight for a fraction of a second, but long enough to notice and have other people in other vehicles notice as well. It is repeatable, and has been repeated by the dealer. It puts my safety at risk. Dealer stated and produced a bulletin that states they are aware of the problem, but do not have a fix for it yet. Bulletin is PIT6203A.

The headlights flicker on and off frequently (every minute to two minutes). This put my safety at risk for not being able to see the road clear and causing a acident. It puts other drivers safety at risk because they get flashing lights pointed at their windshield and can cause and accident. It is also a safety risk because other drivers assume the flickering is being done by me the driver on purpose and I am concerned it will start road rage or another driver to escalate thinking I am road raging at them. Dealer is aware of the problem. No warning lamps. Started with 40 miles on the truck.

The head lights flicker when driving at night.

This truck was purchased brand new on [XXX]. Noticed lights are intermittently flickering (every 2-4 minutes) when driving at night on [XXX]. We took vehicle in to dealership (Jessup Automotive) on 8/23/24 where is was purchased and work order stated, "Engineering is aware of this concern and is working towards a resolution. It is no longer recommended to replace the headlamp assemblies as it has been found that the issue is present in the replacements currently stocked at CCA. This PI will be updated when this direction changes." Other vehicles think you are blinking your lights at them. We took a video. Also, there are other vehicles of people having same issue on [XXX] . The vehicle has been inspected by dealership. We are taking to another GMC to get second opinion. No warning lamps, messages or other symptoms before the failure. Owners on the website mentioned that changing the headlight assembly worked. They stated change module or headlights did not work. This problem has been going on at least since since May 2024. We have paid $40,000 for a truck that we are worried about driving at night. Waiting for call back from GMC now who we called on August 23, 2024 in which they stated they would call back within two business day. I have video, however it won't attach.

The headlights keep flickering. Oncoming traffic thinks I am flashing them for some reason. It’s very unsafe to drive this vehicle at night due to this issue. I would like the issue fixed asap.

Headlights flicker intermittently causing a safety issue when driving at night which could unintentionally signal to other drivers to proceed when you are not expecting or headlights could go out completely at night

Purchased vehicle 8/3/2024 and on way home experienced headlights were flickering. The problem continued and is so bad approaching vehicles will flash their bright headlights at my truck. At a 4 way stop other vehicles think I’m flashing them to go. This flickering makes it impossible to drive safely at night. It’s not only a distraction to me but other drivers as well. I brought the vehicle back to the GMC dealer and was told they were aware of the problem and have no solution to correct it. This is an unsafe vehicle to drive at night and is a distraction to other drivers. The only response from GM is they are aware of the problem.

Head lights flicker while driving at night

My headlights keep flickering on and off. And that has to be dangerous

Headlights flicker once every couple of minutes or so. This could very well indicate me flashing someone to turn or go in front of me. I have seen multiple internet threads of this same issue happening to 2024 GMC Canyon owners. The car has 500 miles on it and I've noticed it since I've had the vehicle. No warning signs or anything. Seems like it is computer related.

The headlights flicker when driving at night. Every minute they turn of and back on quickly. The cars in front think I am flashing them and they pull over to the side or slow down. This started at 200 miles.

Headlights frequently flickering. Flickering varies from 30 seconds to 5 minutes in between. Very random and unpredictable. Service department at the dealership was able to replicate the issue. They found a bulletin, PIT6203 that said to replace the headlights, so they ordered new ones. After three weeks I called the dealer and they said GM cancelled the order because replacing the headlights did not resolve the issue. Headlights flickering has caused other drivers to flash their lights at me. Concerned that other drivers may see my lights flicker and assume I’m giving them to go ahead causing them to pull in front of me causing an accident. Additionally there is a concern my lights completely going out while driving.

Since new headlights have flicker. Took to dealership, they stated that this is a known problem with the 2024 headlights and they have no repair and gave the truck back. NO DATE OF REPAIR PROMISED OR IMPLIED. The headlights are not just an immediate danger on for driver in truck but on coming traffic. I have been pulled over for "flashing" a police officer, flip off from other drivers that think I am flashing them. Please help the entire 2024 canyon population as this is a common problem.

Lights flickering while driving at night

Headlamps flickering. At first the automatic high beams were causing an issue so I turned that off then it was the headlamps while running normal continue to flicker while driving.

The contact owns a 2024 GMC Canyon. The contact stated that while driving at various speeds, the front headlights were flickering intermittently. There was no warning light illuminated. The vehicle was taken to a dealer where the failure was acknowledged; however, the contact was informed that mechanics were not authorized by the manufacturer to repair the vehicle. The manufacturer was also notified of the failure but offered no assistance. Upon investigation, the contact discovered Technical Service Bulletin: PIT6103A; which was linked to the failure. The vehicle was not repaired. The failure mileage was approximately 50.

Headlights flickering/blinking every 1-3 minutes intervals when on. This bothers oncoming traffic.

Headlights flicker all the time regardless of speed Radar cruise control will slam on the brakes for no reason even when there's nothing in front of me. (Seems to happen more at night) Blindspot monitoring will randomly turn on for no reason

Headlights flicker randomly

The headlights go off and on. Sometimes they flicker.

Headlights Flickering frequently while driving or parked. Causes other drivers in front of me to think I am high beaming them or flashing my lights at them. Causes quick moments of darkness and is disorienting when driving at night. No warning lights or signs of damage. This issue has been reported by many other vehicle owners and currently GM has not published a solution. Other vehicle owners reported that dealerships did not resolve the problem after replacing the headlight module and updating firmware. The solution is believed to be to replace the headlight assemble due to bad diodes during manufacturing. Headlights have done this since I bought the car.

The headlight assemblies randomly flicker, and occurs while driving and while parked. It includes the HID headlights and the LED daytime running lights. The dealer has confirmed that the issue exists with this model vehicle; however, there is currently no fix.

The headlights on the truck turn off for a split second and continue to do so randomly. If I had to guess they are turning off and on every 5 minutes. This causes people in front of me to think I am flashing them and the bigger concern is if they were to not turn back on again. The dealer I brought it to said that GM is currently working on a software solution to figure out the problem. Researching this issue online I found that there is a TSB already filed (PIT6203) for this issue and it sounds like there is some success fixing the issue by swapping out the headlights but does not always fix the issue. GM has not come out with an official solution for this widespread issue yet.

Both headlights flicker every 1-2 minutes, does matter if switch is on automatic or on.

Headlight flicker, affects day time running light, low beam, high beam and possibly taillights. Lighter flicker off and on periodically about every 1-2 minutes consistently regardless of driving or parked, and regardless if the lights are switched on automatically or manually.

Front headlights, marker lights, and drive lights flicker off and on while vehicle is running and while driving at night.

Headlights flickering

The headlights have an occasional flicker.

Headlights blink intermittently and separately. Have taken to dealer but was told GM does not have a fix at this time. Have noticed numerous complaints of same problem from other GM Canyon and Colorado owners.

As I've heard many others report, my Canyon has the headlight flicker problem that seems to be plaguing these vehicles. Driving during the night, the headlights will periodically go out every couple of minutes. It is very brief (less that 0.5 second) but very distracting and cannot be safe for other vehicles on the road.

Headlights are continuously flickering and GM does not have a solution. This is concerning because drivers think I am constantly flashing my lights at them which has resulted in them flashing their brights at me. This could cause an accident, so I am very concerned about driving the truck at night. GM needs to address this immediately before someone is hurt.

Headlights constantly flicker and causes dangerous condition driving at night

The headlights while driving will flicker completely off. This happens during the daylight lights are on and at night when main headlights are on. This is very dangerous and concerning while driving at night when I have to drive on country roads where the headlights are vital. This issue also creates unnecessary confusion with other drivers as they are under impression I'm flashing my lights at them.

Every few minutes the headlights flicker. GM does not have a fix for this currently.

Driver’s and passenger side daytime running lights and headlights flicker off randomly. This creates the potential that the lights may fail while needed at night leaving the driver without forward illumination. It has lead to drivers in front of me thinking I’m flashing my lights at them while following which in turn the driver in front of me slows down excessively in protest of their belief that I am flashing lights at them. I’ve also had oncoming traffic flash their high beams at me believing I activated my high beams at them thereby creating an unnecessary blinding situation. The flashing could be interpreted by either oncoming traffic or a pedestrian that I am yielding the right of way when I actually am not and lead to a motor vehicle accident or a pedestrian being struck or at minimum put at risk.

Headlights turn off and on randomly every few seconds. No fault lights on dashboard. Dealership confirmed issue exists. Dealership was advised to replace control module by GM. This did not fix the issue. Advised to change headlight assemblies but they are backordered with no ETA. This issue causes confusion to other drivers and is a safety hazard while driving at night. No recall issued yet.

Headlights flicker on and off randomly. Anywhere from every 30 s to a couple of minutes.

Headlights flicker every couple of minutes. Very concerning driving at night. Incoming traffic thinks I’m flashing them. Not good these days. Contacted dealer. They are aware there is a problem. They stated that GM has not come up with a fix yet. To me that answer is unacceptable.

Flicking headlights

The headlights flicker on and off. Possibly to stay off. Other pedestrians think I’m singling them to cross in front of me when I’m not. Other drivers get angry because they think I’m flashing my high beams. This is a huge safety issue

Headlights flicker on and off constantly.

The headlights randomly flicker.

Headlights flickering on and off at night.

Been experiencing an intermittent issue. After completing an indicated right hand turn, the vehicle will signal a left turn for 3 blinks. This is a safety issue because the vehicle is signaling a left turn when no turn is intended.

Headlights flicker

Headlights flicker independently randomly. Does not matter what position headlights are in (auto, on, highbeam). GM looked and confirmed issue but said to not replace any modules or other parts until they can redesign the headlights. Happening on all 2024 GMC Canyons. Issue during daytime driving could lead to road rage. Issue at night is worse obviously because it is very distracting to oncoming and other drivers. Police could think you are trying to warn other drivers of their presence which would lead to a citation but mostly the distraction and irritation to other drivers is going to lead to an accident or worse. GMC needs to recall these Canyons and get a fix immediately.

Headlights flicker every minute or so. Sometimes every few seconds. Makes it appear that I’m flashing oncoming traffic or those I’m following. Appears GM has known about it for months but no fix yet. PIT6203A

The vehicle headlights flicker off and on intermittently, sometimes within a few seconds of each occurrence, other times several minutes between flickering off and on. The flickering is distracting to the driver of the vehicle and to other drivers as well as oncoming drivers flash lights back. The dealership has been notified and they are aware of other complaints on 2024 GMC Canyon vehicles. This is a known issue among other owners and apparently GM as the issue has been voiced on social media sites related to the Canyon and on Canyon related group forums.

Headlights keep flickering/turning off and then back on

Headlights blink intermittently when driving. The issue occurs every 2 min or so. The blinking may be construed by other road users as an indication to move over or other unintended confusion. Issue has been documented in a video.

The headlights flicker, randomly turning off/on, hi low not sure but it’s definitely distracting and annoying to other drivers

My 2024 GMC Canyon AT4X picked up on Saturday 8/10/24. First time driving it at night I kept noticing a flickering of the headlights. I confirmed after reading multiple complaints online about the headlight blinking on many GMC forums. I have a video of it and have shown it to the dealership service department. They are ordering a lighting control module for the headlamp assembly. Very concerning that a headlight malfunction with less that 20 miles on the vehicle. And very noticeable at night almost looking like you are flashing your headlight at drivers in front of you.

When driving at night or anytime for that matter, and the low beams are engaged, the whole light housing will momentarily shut off and turn back on. This can cause safety issues, especially since it looks like you are flashing people. It happens randomly and affects both the driver side headlight and passenger side headlight. It will only stop if you turn the entire headlight housing off, or only have the daytime running lights on. I am unable to attach videos. This issue seems to affect 2024 GMC Canyons manufactured after April 2024.

Both headlights intermittently flicker on and off during operation. This is distracting for the driver while driving at night, and also distracts other drivers both ahead and oncoming. Dealer has reviewed the issue and is awaiting direction from the manufacturer for best way to resolve. No warning lamps or fault codes occured. The issue began within 30 minutes of purchase leaving dealership.

Headlights flicker every five seconds at night. Could be a hazard to oncoming traffic.

Head lights flicker on and off both sides in a rapid succession. Lasts 2 seconds maximum then works for a few minutes before flickering again. This has happened since 50km of owning the car.

I was driving at night and noticed both headlights would flicker off and then back on. Oncoming drivers on the highway were flashing their highbeams at me because they thought I was flashing my lights at them. My girlfriend was driving her new motorcycle home in front of me and had to pull over to ask why I kept flashing my lights at her. It was a very hazardous situation. The dealership ordered two new headlights for my vehicle and took several weeks to repair it.

This vehicle has an intermittent headlight flicker that is a distraction to myself and other drivers. GM is aware of the issue but has yet to provide a resolution.

Headlights flickering at approximately. 1 - 2 minute intervals

LED Headlamps blink off and back on in a fraction of a second. Seems to be related to low beam setting. Seems to not be related to auto-dimming functionality. Seems to be a narrow build date window from late Spring 2024 thru June 2024. Occurs when vehicle is moving or parked. Can be replicated in daylight by manually turning headlights on in the control center. GM documented with Document ID 6691954 "#PIT6203: Headlamp or DRL Flicker or Flash (July 16, 2024) Possible hazards include oncoming drivers being flashed from flicker. Oncoming drivers thinking they're being signaled by the flicker. Pedestrians or cyclists thinking the flash or flicker is signaling them to proceed and that vehicle operator will yield. Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving. Please consider escalating this issue to a formal recall due to dangers outlined above.

The led headlights flicker randomly while driving. This is very distracting to me and the vehicles in front of me. I just purchased the truck Friday (8/9) and noticed it on my way home from the dealership.

Both headlights and daytime running lights flicker on and off while driving, at night this has proven dangerous for myself and oncoming drivers being flashed by me constantly.bran new truck day 1

LED Headlamps blink off and back on in a fraction of a second. Occurs when vehicle is moving or parked. Can be replicated in daylight by manually turning headlights on in the control center.

Oncoming drivers thinking they're being signaled by the flicker. Pedestrians or cyclists thinking the flash or flicker is signaling them to proceed and that vehicle operator will yield. Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving. Since the PIT6203 was created (with the recommended action of replacing headlamp assemblies), GMC is now advising to NOT replace them, but offers no further solution. I've received no official word from GMC or the dealership on that, but while they explore a solution, I'm driving a brand new vehicle with a potentially dangerous manufacturing / build flaw. Please consider escalating this issue to a formal recall due to dangers outlined above.

Headlights and DRLs flicker at night when in on position. GMC with no fix and no timeline as to when. Safety issue driving at night. First started at 49 miles on odometer. Now at 1800 miles and still ongoing.

HEADLIGHTS FLICKER OFF AND BACK ON AGAIN INTERMITTENTLY / OTHER DRIVERS ON THE ROAD THINK YOU'RE FLASHING THEM / KNOWN ISSUE PUBLICLY VEHICLE IN DEALERSHIP WITH NO SOLUTION FOR OVER A MONTH / NO WARNING LIGHTS OR CODES TO ACKNOWLEDGE

Headlights consistently flicker. I have had other drivers stop me and warn me. Happens every 1-2 minutes on both sides. GM dragging their feet with a repair. I am hearing multiple customers with the same issue. Please put pressure on GM to correct this issue now!

Headlights have a frequent flickering issue. They are constantly flickering on and off. Truck only has 600 miles on it.

Both headlights blink randomly. Causes unsafe driving conditions at night as well as possibility for road rage interaction at any time.

My headlights flicker or blink without warning and I feel that they could fail while on the highway. I purchased my truck on the 1st of August 2024. Gm had issued a service letter for the problem on the 30th of July 2024 but they still sold me truck without mentioning the defect.

Lights flicker when driving at night. Drivers think I am flashing, flicker causes a distraction on the road. GM service denies the issue. No warnings. Happens every 5 minutes.

About every five to six minutes my headlamps will flicker. Googled online and found a forum for Colorado and Canyon owners who are experiencing the same thing. Some people on there have said GM is aware of the problem.

Headlight flickering causing vehicles infront of my truck to slow down or break. Been to dealership multiple times for headlight problem. Recent headlight assembly replacement. Headlight flickering still present in truck after headlight assembly replacement. Blind spot indicators intermittently work, on highway, had couple times I relied on indicators that did not illuminate. Dealer could not find issue but same day I picked up truck from service, blind spots weren’t picking up some vehicles either passing or getting passed. Steering wheel noise when turning. Dealer took part steering column, but could not find a problem. Was told it was just sound from motor in steering column. Test drive exact model truck and year, no noise from that truck while turning steering wheel

Approximately every minute while driving with the headlights on, they will turn off/flicker for a split-second. This makes it seem like I’m flashing my lights at other vehicles, and also makes the lights turn off while driving for a split second which is distracting. This has happened since the vehicle was purchased new and it happens any time the headlights are turned on.

Headlights are flickering intermittently, causing oncoming drivers to think they are being bright lighted. Which causes them to bright light me. Also, headlight flickering causes trailed vehicle drivers to think I am signaling them to stop. Both situations are hazardous, in my opinion.

Headlights blink or flicker off and on. Both will do it but not at same time. Seems to be only low beams and happens driving or parked. Have been to dealer and they saw it happening. GM is aware and have a bulletin #PIT6203 Headlamp or DRL Flicker or Flash (July 16, 2024) and #PIT6203A ( July 30, 2024 ) Concerns are other drivers or pedestrians think I'm flashing my lights at them signaling to pull out or walk in front of me. I'm afraid one of these times they will not turn back on.

LED headlamps on both sides of vehicle routinely "flicker" / "blink". The effect is such that oncoming traffic assumes you are "flashing" them or "high beaming" them. Have had several encounters with motorists honking at me or yelling as I pass by. I was also break checked by a vehicle in front of me on the highway when driving at night. These incidents have made driving at night very stressful..... and potentially dangerous. Dealership has been notified and initially stated that they would replace headlamps and ordered those items. I day before my appointment , they cancelled and said that GM was no longer replacing headlamps and was "working on a fix" PIT # 6203A. No time table has been given. This issue is apparently widespread on 2024 Canyons built between March and June of 2024.

Headlamps flicker intermittently, every 2-5 mins. Common problem and well documented/discussed on owner forums. There was a tsb issued by gm, bit it was rescinded shortly thereafter. No fix is currently known. Headlight flickers cause other drivers to flash their headlights back at you, as well as other aggressive and unsafe behaviors by other drivers.

The headlights flicker constantly at night. They very quickly power off and back on appearing to other vehicles as if we are flashing our lights. This is a common issue among the 2024 gmc canyons in the facebook owner groups. Its a safety hazard and could also provoke other drivers.

The contact owns a 2024 GMC Canyon. The contact stated that while driving at an undisclosed speed and attempting to slow the vehicle while in traffic, the brake pedal was depressed; however, the vehicle failed to slow as quickly as needed. The contact stated that the brake pedal required increased effort to slow the vehicle. The ABS and traction control warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed failures with the brake master cylinder and ABS control module. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 250.

Headlights flicker off and back on randomly every few minutes. Possible hazards include oncoming drivers being flashed from flicker. Oncoming drivers thinking they're being signaled by the flicker. Pedestrians or cyclists thinking the flash or flicker is signaling them to proceed and that vehicle operator will yield. Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving. Please consider escalating this issue to a formal recall due to dangers outlined above.

Headlights began flickering two days after purchase of vehicle. Infotainment screen that operates the headlights, as there is no physical headlight knobs or buttons, also malfunction and is inoperable. So I can not turn my headlights on or off, they're set to auto and I can not adjust it. Service department at my dealership has been able to replicate my issues and are trying to fix them, but parts availability is an issue. GM has informed me that the parts are delayed with no eta of when they would be available. Issues with the headlights flickering could lead other drivers to think I'm flashing my lights at them as I'm telling them to go ahead and that could cause a wreck. Also with the flickering there is a chance that the lights could completely cut off or go out and if I'm driving at night that would be a very big issue. Especially since the Infotainment screen that I need to operate the headlight functions is also inoperable. The Infotainment screen is also on national backorder per GM. GM documented with Document ID 6691954 "#PIT6203: Headlamp or DRL Flicker or Flash (July 16, 2024) Possible hazards include oncoming drivers being flashed from flicker. Oncoming drivers thinking they're being signaled by the flicker. Pedestrians or cyclists thinking the flash or flicker is signaling them to proceed and that vehicle operator will yield. Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving.

The headlights on the vehicle will flicker/ short out. This creates a high risk when operating the vehicle at night. Vehicle was brought into the dealer for service on 08/05/2024, was told there is no current solution for this problem at this time. No warning light on the dash.

The headlights flicker independently every few minutes. This occurs no matter what setting the headlights are on (automatic or not). This has been an issue since purchasing the car new in May.

LED Headlamps blink off and back on in a fraction of a second. Seems to be related to low beam setting. Seems to not be related to auto-dimming functionality. Seems to be a narrow build date window from late Spring 2024 thru June 2024. Occurs when vehicle is moving or parked. Can be replicated in daylight by manually turning headlights on in the control center.

LED Headlamps flicker off and on and occurs repeatedly every few minutes. Occurs when vehicle is moving or parked. Occurs in a controlled lighting environment meaning it is not due to the auto-headlamp sensor being triggered by light or darkness changes. There are no error or fault warning messages that display on the dash or control center. No human involvement triggers the flickering. The issue occurs even when remote start is used and the vehicle is unoccupied. I have located dozens of other owners with the same issue with a similar build date from Spring 2024 through June 2024. GM documented the issue with Document ID 6691954 #PIT6203: Headlamp or DRL Flicker or Flash (July 16, 2024). Hazards include the possible signs of headlight catastrophic failure rendering the driver unable to see the road and surrounding vehicles as well as other drivers being unable to see you that could result in injury or death. Vehicles that are being trailed when the flickering occurs interpret the action as being indicated to rush and make way for the approaching vehicle resulting in road rage actions such as brake checking or other forms of violence that can result in injury or death. Pedestrians may interpret the flicker as the driver yielding to them resulting in the pedestrian entering the path of a moving vehicle resulting in injury or death. Oncoming drivers that are being flashed from the flicker are distracted or blinded in a way that could result in injury or death. Please escalate this safety issue to a formal recall due to severe consequences that could result from the faulty headlamps.

The headlights are malfunctioning where they periodically flicker and there is a loss of lighting. The frequency seems to increase the longer the headlights are on and in use. The loss of lighting during the event increases risks of driving at night and impairing oncoming traffic. Yes, the problem has been confirmed and documented by my dealer, Ideal Buick GMC in Frederick MD Yes, Dealer inspected the problem, replaced parts but the problem still exists. No other indications of failure. Symptoms appeared immediately after taking delivery of vehicle.

The valve body on GM's 8 speed transmission is a known fail point for many GM truck owners. I believe the NHTSA should investigate this for the extreme risk of an accident. My truck has been inoperable for a month awaiting a back ordered part. When driven, the truck displays erratic behavior and will downshift and decelerate rapidly and without warning. The risk of being rear-ended is very high.

Headlights blink every 2 to 3 minutes.

Headlights in on position, every few minutes both left and right headlights along with DRLs flicker off and back on very quickly.

Both front headlights flicker every few seconds

Front low beam headlights will flicker on and off for a second while driving or sitting at a stop in auto or constant on mode. They will flicker every 2-3 minutes causing cars to flash and brake check you as they thing you are flashing your lights at them.

Since buying this truck new in june of 24 the headlights will flicker. Randomly as you drive or when parked the headlights will turn off for a second then come back on. Often at night the lights flicker numerous times

The headlights randomly flicker on and off while driving at night. This not only causes a distraction while i'm driving but is also affecting other drivers. Drivers in the other lane keep mistaking the flicker as me turning on my bright lights which is leading other driver to retaliate and either put on their bright lights or flash their brights at me. I also had one instance where a car I was following thought I was continually flashing my head lights at him and he proceeded to get behind me and tailgate me with his bright lights on. Due to the frequency of the issue and the unknown cause I fear that at some point the lights will go out completely while driving at night. The truck has been taken to the dealer an they state they are unable to reproduce however there is an only forum where multiple owners are reporting the same issue. I also posted a video to youtube demonstrating the issue [XXX] ). Here is a link to the forum where other owners are discussing the issue [XXX] ). Vehicle has only been inspected by the Dealership. There were no warning lamps, messages, or other symptoms prior to the failure. The vehicle is new and the issue has been present since the truck was new.

I was driving with my cruise control set at 77 mph in the fast lane of a four-lane highway. There was no one in front of me for more than 3/4 of a mile. A car in the lane to my right apparently triggered the automatic breaking system to the point it slammed on my brakes, pushed me into the steering wheel, and slowed me all the way to 38 mph in the fast lane of the freeway. The result of this unrequested breaking caused four cars behind me to almost rear end me and pile up. The second event was going down the freeway with the cruise control set at 65 and nobody around me and the car again slammed the brakes on for no apparent reason. At this point I’m afraid to drive the car. I have zero confidence in this vehicle letting me operate the vehicle. I need help.
