2022 KIA EV6

My ICCU failed while I was driving and I lost power while in a light controlled intersection in Chicago. The screen turned off and I could not see my speedometer or any driving information. I luckily was able to roll to the side of the road and park the car. My car could not change gears, doors would not work, trying to jumpstart the 12V did not work.

The electrical system failed (dashboard warning light appeared while in park) and then a pop was heard (fuse bursting). Car could not safely drive. Dealer confirmed ICCU failed once checked at dealer. No prior warnings noticed and no issues charging with approved systems leading up to the failure.

Started car. Heard a pop in the back seat area and then an error message appeared on the dash.

I had an ICCU failure. There were no warning lights . The dealership initially could not find the problem but when I brought it back again they did confirm the ICCU failed and replaced it. Failure of this causes the car to stop driving and lose power causing you to stop on the road as well as be unable to charge the car.

In November 2024, my 2022 Kia EV6 became suddenly non-drivable due to electrical failure consistent with a repeat ICCU/12-volt system malfunction. The vehicle would not start or maintain normal electrical power and became stuck in accessory mode, creating a loss of propulsion and complete loss of transportation. This vehicle previously experienced an ICCU failure earlier in 2024 that required dealership repair and battery replacement. After that repair, the vehicle again developed electrical failure symptoms, including loss of 12-volt power and inability to operate. Due to the unsafe non-drivable condition, Kia Roadside Assistance directed and arranged a tow to a Kia dealership. Upon arrival at the dealership, new undercarriage and wheel-well damage was documented within approximately 90 minutes of drop-off. This damage was not present prior to towing and is located where tow equipment attaches. The vehicle remains in the possession of the dealership and is available for full inspection. The electrical failure created a safety risk because the vehicle became immobilized without warning and could not be safely operated. There was no advance notice or driver-caused event. The failure resulted in complete loss of vehicle function. The vehicle has been inspected by a Kia dealership, and I have been working through Kia corporate and roadside providers since the incident. The vehicle remains out of service with unresolved electrical issues and unresolved damage resulting from the manufacturer-directed tow.

MY DRIVERSIDE FRONT DOOR WON'T OPEN, WHEN DOOR IS UNLOCKED, BOTH OUTSIDE AND INSIDE HANDLE WONT'T OPEN THE DOOR. YOU HAVE TO CLICK ON THE UNLOCK/LOCK BUTTON 15-20 TIMES TO GET THE DOOR OPEN. ALL THE OTHER 3 DOORS WORKS FINE.

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.

Software updated for recalls still have ICCU failed.
