Driving down local (residential) roads, the ICCU died; towed to dealership 12/3/2025. All 12 volt electrical was inoperable. So no hazard lights, no shift to neutral, no locking the doors.

ICCU and fuse failure when it was being moved out from the garage. Got a “Check electrical system” notification when I turned it on following a level 2 charge the night before. It was with the dealer for exactly one month before I was able to pick it back up.
