NHTSA Complaint #11558411 — 2023 CADILLAC LYRIQ

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.
