This one was abandoned at the San Francisco Airport, and sat at the tow company for a few months unplugged. It last reported to Tesla battery health on March 13th. It was sold in mid-July, and the salvager immediately had it towed to Tesla for analysis.
Everything works on the car, but L2 charging at least is blocked by the BMS. So kiddies, set your state of charge and leave your cars plugged in while on vacation. Unless you have an older Leaf, where that will kill your 12V battery (unless you have my customer double charger that L2 charges the main battery and the 12V battery at the same time).
