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.
