NHTSA Complaint #11712107 — 2022 KIA EV6

I am reporting a failure related to the Integrated Charging Control Unit (ICCU) on my Kia EV6 vehicle. The vehicle suddenly became unable to charge using Level 1 or Level 2 AC chargers. Each time the charging cable is connected, charging starts briefly and then stops within seconds with a “charging unsuccessful” warning. The issue occurs consistently across multiple chargers. However, DC fast charging (Level 3) still functions, indicating a failure specific to the onboard charging system. In addition to the charging failure, the 12-volt battery became abnormally depleted, which required external charging to prevent the vehicle from becoming completely inoperable. This raises safety concerns, as a drained 12-volt battery can disable critical vehicle systems. This appears consistent with widely reported ICCU failures affecting Kia EVs. The failure occurred without warning and has rendered the vehicle unreliable for normal use. Because the vehicle cannot charge at home or on standard public chargers, it creates a safety and mobility risk, especially if the vehicle becomes stranded due to 12-volt system failure. I am concerned that this is a systemic defect in the ICCU that impacts vehicle reliability and safety and should be investigated further.
