Warnings problems of the 2024 GMC Canyon

Vehicle alerted driver that ecs and. Rake assist was needed and disabled abs and forward collision while lighting up multiple warning lights on dashboard. Lights eventually turned off leaving a check engine light on. Multiple codes pulled from system using obd2 reader. Communication bus b offline and u0074, u0151, u0447,u0452 all at same time.

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

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.

I purchased my truck with 5 miles on the speedometer in anchorage ak 4/7/2024. In may 2024, the engine idled rough and transmission shifted hard, I was told me it was normal, and I would have to wait 2 yrs to make a transmission appointment. In June 2024 approaching a green light, approximately 35 mph, the brakes locked, I had no control over the steering and it left a 5 foot skid mark. I had a painful neck and headaches. The shop said they couldn’t make it do it again. In August 2024 approaching a stoplight at 40 mph, the brakes locked, would not release, gas didn’t work, I had no control over steering this left 6-7 ft skid mark, the vehicle also had electrical issues the interior dash lights would go black, very bright, interior lights would flash, the radio would stop working. The manager took my truck home and said I should shut the forward collision and pedestrian warning system off. I was in communication with gm customer care who informed me they could not help me. The dealership ran my truck into a cement post, causing $2000. Now sometimes the brakes randomly stop working, the throttle stuck open, and the trans is worse. It’s not safe to pull a trailer or take people with me. It’s out of warranty and dangerous. I drive on edge not knowing what’s next. It’s $8,200 to fix the transmission, the front radar camera needs replaced, and electrical fixed by a quality shop.
