Hi,
Day3 (conclusion): my car is ready. It's apparently a bug in the software, my car thought I was inside when I was not there, so ventilation, radio, etc was on until the car died. FYI I am on 2020.12.5 and it's an SR+.
edit: ... and they change the 12v battery also.
Thank you
did you notice the radio, hvac were still on when you closed the door? Did it lock when walking away?
