2023 GMC Canyon Lane departure Problems

“The blind spot monitoring system comes on and off (false positives) while driving at night with no cars behind or next to me. It is a serious distraction requiring the driver to take there eyes of the road. I took the truck to a GMC dealer and they said they could not replicate the issue. I no longer drive the vehicle at night.”

“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.”

“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. …”

“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. …”

“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.”
