NHTSA Complaint #11698660 — 2022 KIA EV6

The ICCU (Integrated Charging Control Unit) failed while the vehicle was charging at my home. It tripped the 60A circuit breaker for my EVSE circuit and now my EVSE is inoperable. The vehicle no longer charges via AC (Level 1 or Level 2) at any charging station. Attempting to charge the vehicle triggers a safety fault error on the EVSE indicating an electrical problem with the vehicle. Additionally, attempting to use the V2L (Vehicle to Load) adapter on the vehicle causes audible arcing sounds from the ICCU accompanied by a "Check Electrical System" message on the vehicle's display. These symptoms indicate a complete failure of the OBC (On-Board Charger) circuit inside of the ICCU. The arcing is most likely coming from a failed MOSFET. The ICCU has been recalled twice in this model, however it is clear that the software update "remedies" are not satisfactory. I had the most recent recall campaign SC327 completed during the month it was released in November 2024, yet it still failed only a year later. Reports of ICCU failures are constantly being posted online from "remedied" Kia EV6 vehicles. Software cannot fix a hardware design fault. The part should be redesigned to correct the cause of the defects and, if Kia doesn't want to replace every ICCU with new hardware, the warranty on the ICCU should be extended to unlimited miles and 15 years.
