2024 GMC Canyon problems, recalls and owner complaints

2024 GM Canyon bought brand new in December 2024, now has 24,700 miles and the front brake pads are down to 2% per the GMC dealership service department. Premature brake wear, and GM is refusing to pay for it.

I purchased my truck with 5 miles on the speedometer in Anchorage AK 4/7/2024. In May 2024, the engine idled rough and transmission shifted hard, I was told me it was normal, and I would have to wait 2 yrs to make a transmission appointment. In June 2024 approaching a green light, approximately 35 mph, the brakes locked, I had no control over the steering and it left a 5 foot skid mark. I had a painful neck and headaches. The shop said they couldn’t make it do it again. In August 2024 approaching a stoplight at 40 mph, the brakes locked, would not release, gas didn’t work, I had no control…

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.

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.

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.

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.

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.

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
