The automatic emergency braking system on our 2023 GMC Canyon engaged suddenly 3 separate times while we were driving at around 50 MPH on a clear, straight road with no obstructions. We brought the truck to the dealership the next day, and the service department said it was a software issue and reprogrammed the truck's computer. This did not fix the problem, and we experienced the same unexpected automatic braking while driving at 50 MPH on a clear road. We brought the truck to the dealer again, and it has remained there ever since. This poses a risk for sudden unexpected stops, loss of control of the vehicle and rear end collision. There were no warning lights to indicate a problem. In addition, the blind spot indicator light on the drivers side starts blinking when there is nothing in the blind spot. We first notice the problem July 23, 2026 and it recurred on August 6 2026.

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.

Since I purchased the vehicle it’s had the issue of it braking on its own. I brought this up to GMC many times. At the beginning they had me try to duplicate it with them, which I thought would be unsafe. They only acknowledged the problem and attempted repairs after I contacted GMC directly. The issue with the crash alerts while driving always stayed, even though there was nothing in front of me. Just recently it started braking on its own again in traffic. This has caused bodily and property damage, luckily nothing grave. I do not feel safe in the vehicle and gave gmc many attempts at fixing such a serious issue. I want them to tow replace the vehicle and provide a loaner. Please contact me if you need more details.

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.

On 12/2/2024 my vehicle abruptly alerted and auto braked while drive <25mph on residential street while attempting to drive in between two parked cars. Plenty of room but system thought there was going to be a crash. Another vehicle was traveling behind me and also had to stop fast in order not to hit me because of the emergency braking. Truck almost came to a full stop but brakes released and was able to continue driving. This is after I had a mandatory software update that was supposed to improve the over aggressive auto/emergency braking feature. I have since had to disable the braking portion of the system and leave it on audio alert only. Not functioning as designed and unsafe.

Blind spot monitor system continues to give false alerts when no vehicles, objects or other items within blind spot area. Warning light will sometimes stay on for many miles and will go off when I pass another vehicle then go back on when nothing in blind spot again (opposite of design). System will sometime not activate when vehicle is in blind spot. See video. Dealer and GM involved, had PIT6103 performed, replaced all switches April 19, 2024 except for driver door. Issue seemed to improve but has returned and even worse that originally. This has become a safety concern for me as I will apply turn signal, look in mirror, over shoulder but then as I start to switch lanes, the mirror light will start blinking and alerting me there is something in blind spot when there isn't anything there. Causes me to abruptly swerve back into my original lane causing potential dangerous situation. Truck at dealer 12/10/2024 for same issue, dealer and GM tech service states vehicle operating as intended. Was told to either turn system off or live with it. I have multiple videos but unable to upload them here. Please contact me for more info.

Continues to give false alerts even on single lane roads or will not detect vehicles at all. Intermittent issue but happens frequently. Both mirror but mostly passenger side. Becoming safety issue by not knowing if something is there or not. It flashes and alerts me aggressively when it thinks something is there and I turn on my turn signal. Been at dealer three times, TSB performed to replace driver window switch but issue still present. Dealer says they have no fix.
