Consumer Description

The vehicle lost its ability to charge via AC power sources (level 1 and level 2), and the "Check vehicle electrical system" warning appeared on the dash. When using an OBD scanner, DTC P1E01 was present. It was inspected by a dealer, who informed me that the ICCU is in need of replacement, despite this component having been already addressed by a previous recall. Unfortunately the replacement component is backordered and there is no ETA available on the fix. For the time being I am limited to level 3 DC fast charging, which is a major inconvenience but does not represent a safety risk to myself or others.
