12V auxiliary battery drain / dead car
2021-2024 Polestar 2s are known for the 12V battery going flat when parked, because the main battery does not always wake to recharge it and connected features keep drawing power; the car can end up dead, unable to start, shift, or unlock. Ask if the latest software was installed and whether the 12V battery was replaced. Budget a few hundred dollars for a new 12V and a tow if it strands you.
