Sorry to hear. A few question, if I may -
1. At what battery gauge level did you store the car?
2. If left fully charged, was it left plugged into an active EVSE?
3. How much have you driven it after storage (i.e., miles or bars)?
4. At what temperatures was the car stored?
Whereabouts are you located, as perhaps one of our forum members with CaniOn might be able to check your pack voltages?
