2024 GMC Canyon Problems

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

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

Vehicle alerted driver that ECS and. Rake assist was needed and disabled abs and forward collision while lighting up multiple warning lights on dashboard. Lights eventually turned off leaving a check engine light on. Multiple codes pulled from system using obd2 reader. Communication bus B offline and U0074, U0151, U0447,U0452 all at same time.

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.

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.

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.

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.

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)

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. 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.

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 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.

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 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.

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 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.

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.
