There was no major safety issue in this instance. My concern is this poses a severe risk if it happened while driving. The car was on and in ready to drive mode but was parked in the garage with climate control on while loading it for going to school. At somepoint between trips to the car over 20 minutes it died with no warning. Some lights behind buttons, the interior lights, and the screens were on but blank. Not a single button in the car would respond. Including hazards or opening the trunk or closing the charging port door. Lights like the LED for the overhead light button blinked and the charging indicator by the charging port blinked a pattern of 1 longer flash and 8 shorter flashes. The car would not shut off or on again another button that was completely unresponsive. The lights and screen stayed on for at least 30 minutes before I left with a Lyft to get the kids to school. An hour and a half later everything was off and it seemed to have no power. At that point I did figure out how to jump it and get it to the dealer. The dealer claims the 12V battery died and that was the only issue and completed the 2 open recalls. There was no indication when I started the car that anything was wrong or the 12v battery was low or needed replacing. There are apparently no error codes from it completely failing while in ready mode. I was only told this happened because it was in park and the 12V battery failed while it was on and parked, if I had been driving I would still have use of the vehicle as the recall outlined for a failed ICCU when the 12V battery drains. They can find nothing else wrong but my concern is that a failed 12V battery could cause this while driving. I was told simply it cannot happen because the software handles it differently when driving. I hope that is correct.
