The contact owns a 2023 GMC Canyon. The contact stated that when applying the brake pedal, the steering wheel would begin shaking. The computer on the center council that displays information, had blacked out. The vehicle was taken to the dealer who diagnosed that the brake pads had failed. The dealer had completed a software update for the main computer however the failure persisted. The vehicle was not repaired due to the brake pads (Part Number 87850375) not being in production for repairs. The failure had become more persistent and now the brakes have failed. The dealer was contacted and confirmed that the part for the repair was unavailable even for purchase. The parts were on national backorder. The vehicle had not been repaired.

2023 GMC Canyon electrical complaints
Page 2 of 2: complaints 11 to 20 of 20, newest first, as owners wrote them.
The theft alarm has gone off five times since I purchased the vehicle in September, dealership has been noted and has been in there for it and still goes off. Display screen froze up and did not reset until I was done driving and the vehicle was turned off for a while. The crash detection light came on and vehicle stopped itself with nobody in front of me or anybody coming towards me. The dealership has had the car for two weeks now, and they say there’s still no fix for it.
The contact owns a 2023 GMC Canyon. The contact received notification of the federal safety agency Campaign Number: 24V133000 (Electrical System, Forward Collision Avoidance). The contact stated that while driving at approximately 45 MPH, the collision sensor lights flashed, and the brakes were applied inadvertently. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 2,800.
Blind zone detection system and door latch system failures. The blind zone detection system is inconsistent and at times remains on with bright lights impairing the drivers ability to see at night. With this inconsistency the driver cannot rely on it properly detecting vehicles within the blind spot. Another known issue is the inability to put down windows with the drivers side door. The alert for this is to service the door latch system which typically comes on while driving the vehicle. This limits the driver being able to safely respond to traffic stops from emergency personnel as well as the ability to evacuate the vehicle through the window if necessary. The dealers that have reviewed these issues say they cannot replicate or fix them.
Blind spot warning system continues to illuminate when traveling on two lane roads with no objects in the blind spot(false positives). Especially the passenger side. I continue to be distracted while driving to check the mirror to see what is there, nothing. Then while traveling on multi-lane highways, both sides will sometimes not illuminate when there is a vehicle present in the blind spot. Both of these examples also happen more often after dusk or during dark/cloudy days. I have not taken into dealer yet for repairs but will soon. No system warning of malfunction on dash, just the false positive lights on side mirrors.
Overly sensitive automatic emergency braking/pedestrian warning. System would alert with lights and audible warning for no reason driving at ~55mph. While turning around in a Michigan left turn, system went off and brakes applied abruptly until I was at complete stop. No vehicles or persons were in front of me. There was a car following closely behind which almost hit me. Fast forward a few weeks later and now forward collision system inop light illuminated on dash and will not go off.
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.

Not until the final day before the scheduled service appointment did the system de activate itself indicating an issue with the forward collision. Most issues occurred while it was either raining or damp outside. Dealer now has vehicle in their possession and confirmed a faulty component that is on backorder with no date. Truck has had multiple other electrical issues since purchase 3 months ago. ~200 miles dealer replaced faulty HVAC module. ~4500 miles Forward collision alert as described above.
