2023 GMC CANYON Forward Collision Avoidance Automatic Emergency Braking Problems

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.

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.

Constant smell of coolant while stopped at traffic lights or idling even worse when the air vents are on, dealership insists it's because the reservoir cap is vented but coolant reservoir is literally a foot away from drivers window even still shouldn't be smelling coolant it's been like this since a month after purchase. Having issues now with auto braking system activating for no reason did this multiple times almost got rear ended on NY State thruway because it activated with no cars near me once it activates it causes the truck to go into a limp mode (won't go over 30 mph) and starts vibrating like it needs a tune up. The radio and digital display often dissappear for no reason can tell speed. I almost got a ticket from state trooper for unsafe stopping i explained everything and was told i could get a safety violation for defective...

Automatic Breaking System. Driving along at 25-30 mph on a snow covered road when all of a sudden alert system sounded and vehicle brakes abruptly applied putting vehicle into an uncontrollable slide. Fortunately there was no one behind and nom on coming traffic. Notified GM Customer Service, as I have a case open for other issues they claim tyhey do not have a fix for. GM's response to the sudden brake application was "OH I'm Sorry"

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.

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...

The contact owns a 2023 GMC Canyon. The contact stated while driving 20 MPH, while making a right turn, the left turn signal activated and blinked three times. The contact stated that the Adaptive Cruise Control intermittently activated the brakes independently, and the Forward Collision Avoidance system activated and forced the vehicle to stop abruptly, almost causing a crash. The Forward Collision Avoidance warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and informed the contact that the parts to repair the vehicle were on backorder. The failure mileage was approximately 2,251.
