Reminds me of renting a zipcar for a few days and parking it in an underground parking lot. When I went to use the car after a couple days, the battery was drained. This happened on multiple occasions with different vehicles parked in the same garage. My best guess is Zipcar has cellular comms to phone home, which enter some weird “always trying to connect” state when cut off from cellular signal underground. Zipcar’s response was to ban me from renting on their platform ever again for too many disabled vehicles.
