GMC Canyon

2022 GMC Canyon AT4 Crew Cab. After the vehicle is shifted into Park and the engine is shut off, the ignition key cannot be removed from the cylinder. The key is physically locked, the steering wheel will not lock, and the vehicle cannot be reliably secured. The only workaround is to restart the engine and cycle the shifter repeatedly until the interlock releases the key. Recurring. Safety implications: operator cannot reliably power the vehicle off in an emergency, cannot lock the steering…

Crash on 5/5 rear ended car - airbags did not deploy . Received concussion and neck injury.

With 94 Miles my brand new GMC Canyon AT4 I leased had a catastrophic failure while i was driving it, the front axle essentially exploded. The findings were that their was no oil/lubricant installed in it from the factory which made this happen. I now have to wait many months for the dealership to repair my vehicle while i have a loaner with a bunch of restrictions on it. And i have to pay my lease the entire time it is being worked on because of a factory fault. If i had been going more than…

The power steering and Stabilitrak systems intermittently fail while the vehicle is in operation. The issue occurs unpredictably, both immediately after startup and while driving. On several occasions, the systems have failed during turns, requiring sudden corrective action and increased steering effort to maintain control and avoid veering off the road or colliding with nearby vehicles. No warning signs or noticeable symptoms are present prior to the failure occurring.

My 2015 GMC CANYON had been running for approximately 10 minutes. I was on the highway driving home from the DFW airport doing 65mph. My wife was we me as we were driving home from a trip to visit our grandchildren. A message popped up on the display that said my power steering had failed, a chime also alerted me. It was immediately noticeable as I could barely turn the steering wheel. If I had been in a turn I may not have been able to control the truck and may have caused an accident. The…

Coolant leak observed at the upper radiator hose quick-connect fitting. The leak appears to originate from the internal seal at the radiator inlet connection. This issue developed without warning and is consistent with a known defect in the radiator hose seal design used in 2023 GMC Canyon vehicles. Vehicle experienced coolant loss and visible residue at the connection point. No visible external damage to the radiator or hose assembly was observed. GM has issued a Special Coverage program for…

The engine coolant temperature sensor has failed on my 2019 GMC Canyon. The check engine light is illuminated, the temperature gauge does not register correctly, the air conditioning has been disabled by the vehicle's computer, and the engine cooling fan continues to run after the engine is turned off. These symptoms are consistent with the vehicle entering fail-safe mode due to loss of a valid coolant temperature signal. The problem was confirmed by an independent mechanic who diagnosed a…

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.
