2014 P85DL with 85,500 miles. Charged it to 100% (233 miles) yesterday to take to the drag strip. We got there at 85% SOC. Did one run and then shut it off while we waited for the second runs. When we got in the car, the messages read “low voltage” “car needs service” “car won’t start.” Then the main screen and IC went black. I tried hard reboot about 1000 times with no luck. Tried to jump start 12volt on both a battery pack and from the tow truck- no luck. Without the screens, there is no way to put vehicle in tow mode. Somehow just before we had to drag it up the flatbed on skates, the screens started working again. We engaged tow mode and towed it to service. The app is not seeing the car, Tesla cannot communicate with the car and it will not drive. My suspicion is either battery or MCU. Anyone had a similar experience? Just bought the car, is this going to be painful (out of warranty)?
