SERVICE BRAKESMarch 29, 2026
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.
ENGINEFebruary 27, 2026
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 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.

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.
SERVICE BRAKESSeptember 30, 2025
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.

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.

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.

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.

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.

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
EXTERIOR LIGHTINGSeptember 12, 2024
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.

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

ELECTRICAL SYSTEM,EXTERIOR LIGHTING,UNKNOWN OR OTHERSeptember 9, 2024
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.

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.

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.

Vehicle headlights flicker on/ off momentarily at random when travelling at night. The flickering is NOT the automatic high beam function.

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.

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.

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.

EXTERIOR LIGHTINGAugust 13, 2024
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.
EXTERIOR LIGHTINGAugust 13, 2024
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.
EXTERIOR LIGHTINGAugust 13, 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.

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.

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.

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.

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.
EXTERIOR LIGHTINGAugust 7, 2024
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.
EXTERIOR LIGHTINGAugust 6, 2024
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 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.

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.

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.

FORWARD COLLISION AVOIDANCEApril 21, 2024
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.
