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.

The pre-collision warning and the lane keep assist are disabled while driving frequently. It does this on its own. I have had into the shop one other time for the same thing. It’s happening more frequently now. Current mileage is 25,153. Also the personal settings on the dashboard reset on its own every five or so key cycles. Obviously there’s some kind of software problem.
I am experiencing two safety issues with my Canyon 1) Forward collision alert system is triggered unnecessarily (e.g., when there isn't a car in front of me, when the car in front is far away and not posing a risk). I took it to GMC a few months back since there was a previous recall for this system and they said they stated it was fixed. It is not fixed. I turned off the automatic braking tied to the forward collision alert because it has previously braked automatically in a dangerous manner. 2) Digital gauge cluster / speedometer is black / blank upon startup about 5% of the time. Since there is no analog speedometer, this means I am driving without knowing my speed. This is very dangerous. I have tried disconnecting my battery and resetting the electronic system but this issue still persists sometimes.
Adaptive Cruise Control has applied brakes multiple times while cruise has been sent at speeds ranging from 55-75 MPH. Vehicle aggressively slowed down 10-20 MPH then picked up speed. No vehicles in sight ahead of vehicle, aggressively applied braking without warning. Aggressive braking could cause traffic behind vehicle to crash into me while driving at high speeds. Multiple other reports of this happening to other 2023-2024 GMC Canyon owners based on comments on Facebook and Reddit with acknowledgement from the manufacturer that this is a know issue they currently are trying to resolve. Issue not isolated to this vehicle. Vehicle has not been inspected by Manufacturer or problem been reproduced dealership. Vehicle goes in for service next week, meanwhile cruise is not being used as it is a safety hazard. No collision warning or any other warnings experienced with this issue. Issue first happened on day 1 of vehicle ownership and has happened 2-3 other times with one instance of it braking and accelerating 3 times over a 2-3 mile stretch of highway with cruise set at 75MPH with vehicle slowing down to around 55MPH before resuming set speed.
