- The 12V battery loses charge after the car sits unused for a couple of days, requiring a jump start to restart the vehicle.
- The Integrated Charging Control Unit (ICCU) fails with burnt connector pins, sometimes tripping the home circuit breaker during Level 1 or Level 2 charging.
- The charging port has overheated during DC fast charging, melting the charging pin and, in one case, causing a fire.
