2023 GMC Canyon complaints

The roof of the vehicle crackles and pops when it is in the blowing section of an automatic car wash. We have never had any experience like this before. The roof of the truck is so flimsy that it was actually dented by the hard blowing of air. I don’t feel like this car is solidly constructed and safe.

Vehicle only two months old with 2000 miles. Service engine light and brake assist service light activated. GMC dealer states brake master cyclinder failure and vehicle should not be driven. Vehicle left at dealer while awaiting replacement master cyclinder. Unknown if this is a widespread problem causing brake failures in GMC and Chevy new model Canyons and Colorados.

The screen in the Truck doubles in picture, freezes and/or shuts down completely. This leaves you with out control of your GPS, radio, blue tooth, head light control and backup camera. Research on the internet has proven this seems to be an accruing problem in this truck, with some even losing their speed information. So far it has resolved itself after a while on its own, thankfully, but each time it happens the black out is lasting longer. In order for the dealership to recognize this problem we must drive to them when its occurring, which hasn't been possible. Owning this truck for 2 months and the issue of losing the computer system has occurred 4 times, this vehicle is not a daily driver.

During normal operations the truck will come to a complete stop. I turned off the ABS and it still happens. It caused a major incident today while I was driving 50mph and it brought me to an abrupt stop on the highway. It’s happened many times but today the driver behind me avoided my truck by an inch. I was then followed y that driver for half a mile when I immediately exited the highway.

Emergency Collison fault problem on the 2023 GMC Canyon Failure Date: 10/22/2023 Driving approximately 45mph while car in front is approximately 50 yards ahead driving at a matched speed as my vehicle and without any prior warning the forward collision alert activated flashing red light on windshield and automatically applying full braking until the truck came to a complete abrupt stop in the center lane of rush hour traffic causing other drivers behind to swerve narrowly avoiding serious accident. I manually DE-activated the automatic braking but kept forward alert on until the truck could be brought to the dealership for diagnosis. Forward alert went off erroneously multiple times the following days without any rhyme or reason. Not until the final day before the scheduled service appointment did the system DE activate itself indicating an issue with the forward collision. Dealer now has vehicle in their possession and confirmed a fault issue. They are working with GM on a solution, but no luck yet.

GM is pushing updates over the air that are permanently disabling the backup camera by damaging the camera control module. Not sure yet how long we’ll have to wait for the part. I’ve heard of many that have been waiting months. They should not be pushing out defective software when it takes out the safety equipment.

While driving to work today in fog, the vehicle auto headlights sensed enough light and turned off. Because it was foggy outside I did not feel safe only driving with DRLs on so I attempted to turn on the headlights using the touchscreen controls. The headlights would not turn on. I have video evidence of the headlights not responding to the touch controls and remaining off despite trying to turn them on.
