Blind Spot Detection Problems of GMC Canyon

Headlights flicker all the time regardless of speed radar cruise control will slam on the brakes for no reason even when there's nothing in front of me. (seems to happen more at night) blindspot monitoring will randomly turn on for no reason.

Headlight flickering causing vehicles infront of my truck to slow down or break. Been to dealership multiple times for headlight problem. Recent headlight assembly replacement. Headlight flickering still present in truck after headlight assembly replacement. Blind spot indicators intermittently work, on highway, had couple times I relied on indicators that did not illuminate. Dealer could not find issue but same day I picked up truck from service, blind spots weren’t picking up some vehicles either passing or getting passed. Steering wheel noise when turning. Dealer took part steering column, but could not find a problem. Was told it was just sound from motor in steering column. Test drive exact model truck and year, no noise from that truck while turning steering wheel.

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.

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.

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.

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.

The rear camera and wire harness for the rear backup camera became corroded and stopped working months ago. This is vital technology that our children have grown up with to ensure the safety of backing up in case something is behind the vehicle including young children, toys, equipment or someone simply walking by your driveway while you're backing up. The service manager at billion GMC in sioux falls, sd (dan dunnagan) said they are replacing tons of the rear cameras due to corrosion, which might be caused by water getting into the system or faulty parts and faulty wiring from the product manufacturer. This is certainly a safety issue. I had it repaired at a cost of $591. 84 for the rear camera and wire harness plus labor. This issue on GMC Canyon and sierra 1500 pickups should be investigated as the rear camera is a vital piece of safety equipment and if a large number of these are faulty, subject to corrosion or poor manufacturing, it should be brought forward to protect consumers.
