2024 GMC CANYON Forward Collision Avoidance Warnings Problems

Vehicle brakes stopped working while driving. Dash board lit up and stated system brake failure. Also stated “do not exceed 43mph”

While driving a two lane road the adaptive cruise control detects oncoming traffic and improperly slows down or breaks unnecessarily. Most of the time the vehicle breaks so hard it will jolts me forward in my seat. I fear another car will be behind me and this will cause an accident. I have had my vehicle in the shop two (2) times to repair the issue. The dealership/service department has been able to replicate the issue by having one of their technicians drive the vehicle. The front camera has been replaced twice and I have been told every time they plug a new camera in the trucks interior and exterior lights "go crazy and flash". GM's response to this issue is "set the gap to mid" or simply "shut it off". They refuse to see this as an issue. Doing my research I found that the 2023 GMC Canyons have...

Collision Avoidance comprised of Following Gap and Alarm / Auto Braking does not function. One dealer after two trips and unable to repair stated that GM is working on a new software update and until that is available repair is not possible. No date was provided by dealer or GM customer service as to when this update would be available. Second dealer stated that system was in fact not functioning, and asked me to return in a couple days, so he could research the issue, He knew nothing about a pending update. Both dealers stated that no alarms or codes were present in spite of failure.

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
