2024 GMC Canyon Owner Complaints

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.

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

7/8/2024

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.

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.”

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.

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

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.

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.

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

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.

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.

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.

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.

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

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.

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)

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

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.

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.

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.

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.

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.

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 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.
