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”

“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'm reporting several serious safety and reliability issues with my 2024 Canyon, including the collision avoidance system triggering sudden braking when reversing and moving forward, a roof damage incident from car wash blowers that required repairs, transmission shuddering and a sensation of locking during downshifts, repeated check engine lights with coolant issues, and limb mode events. These problems affect safe operation.”

“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 over steering this left 6-7 ft skid mark, The vehicle also had electrical issues the interior dash lights would go black, very bright, interior lights would flash, the radio would stop working. The manager took my truck home and said I should shut the forward collision and pedestrian warning system off. I was in communication with GM Customer care who informed me they could not help me. The dealership ran my truck into a cement post, causing $2000. Now sometimes the brakes randomly stop working, the throttle stuck open, and the trans is worse. It’s not safe to pull a trailer…”

“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.”
