Have had zero issues with car till last night. Got in car to leave event, pushed start button, engine started but it wouldn't shift out of park. Pushed ignition to turn off but it would not stop running. Tried several times. Noticed a plug shaped warning light on cluster never seen before. At one point a brief came on that car was plugged in, msg went off, never came back. Then interior lights started blinking crazily, car revved up and down, then it would go into sleep mode. Eventually all electronic controls inside stopped working. It continued to spasmodically start, stop, blink, rev, then over about an hour exterior lights gradually faded - at different rates. Tail lights put on a crazy Las Vegas style blink fest then finally died. Sounds terminal, anyone have ideas or had similar experience? Still waiting to hear from dealer service.
