2023 Cadillac Lyriq Powertrain & Transmission Problems

The 12 volt battery of my 2023 Lyriq died even though the main battery was at 79% charge. The car had sat unused for three days. The 12 volt battery controls the opening of doors, charging ports, and all other accessories. I was effectively locked out of my car without warning. The only way in the car is by using the key in the keyfob and crawling through the trunk. GM has known about this issue, but has not informed owners that this could happen and what to do. They believe it is from an installation of an over the air update stalling, but cannot prove that is definitively the issue. As a woman, I rely on my vehicle to be a place of safety and find it completely unacceptable to be locked out of my car in any public setting. I live in an urban area and have had to rely on my car as a place of refuge from people that I do not feel safe around. Having a jumper from the main propulsion battery to ensure that the doors still work should be integrated and customers alerted at a minimum. I'd rather sit inside a dead car and wait for help, than be stuck outside it or crawling through my trunk.

Manufacturer has replaced and recalibrated headlights on 2 occasions however they will not maintain aim on road. This is consistent and as of now besides the repairs performed they do not know how to rectify this. Additionally in the rain or moving from a shadow to sunlight the rear cross traffic alert will trigger if enabled on vehicle causing emergency braking for no reason. it will continue to happen until turned off and car restarted. The car has been towed on 3 occasions in the first 4000 miles for complete loss of power. Dealer solution to remove 12v battery and reinstall same battery to clear elcectrical codes however problem keeps occurring.
