I expect it's purely coincidental, but has anyone else had a 12v battery fail on FSD Beta 10.12 (2022.12.3.20)? With no prior battery symptoms or warnings, mine was dead this morning, about 30 hours after installing 10.12. I jump started using the wires behind the front tow cover and drove about 15 miles to the service center. Using FSD on the way there, visualizations were accurate, but decision-making seemed much less capable than drives with the same software version the day before. Although it could be related to bad 12v voltage regulation with the degraded 12v battery, it seems odd that Tesla would let it engage if supply voltage is not stable enough for FSD.
