2023 Kia EV6

ICCU failed despite all prior recall updates being performed. Incident began when home circuit breaker tripped; vehicle subsequently refused Level 1 charging with "Check Electrical System" warning. Per dealer suggestion, tested public chargers. Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.

My vehicle has been in the possession of Koons Kia of Owings Mills since March 15, 2026, for diagnosis and repair of this issue, with service beginning March 16, 2026. During this time, the dealership has replaced the 12-volt battery and performed a software update; however, the defect has not been corrected. On April 10, 2026, I was notified that the vehicle was ready for pickup. When I arrived on April 11, I found that the battery was completely discharged and the issue had not been resolved. Because the vehicle was not operational at the time of attempted pickup, it was not returned to me and remained in the dealership’s possession. I was contacted again on April 13, 2026, and informed that the vehicle had been repaired. When I returned to the dealership on April 14 to retrieve the vehicle, I again found that the battery was discharged and the defect persisted. As a result, the vehicle was not returned to me and has remained continuously in the dealership’s possession since March 15, 2026. As of today, the vehicle has been out of service for more than 30 consecutive days due to this defect, and multiple repair efforts have failed to resolve the issue. This ongoing condition substantially impairs the use, value, and reliability of the vehicle.

Got in my car to leave a store and heard a loud pop and noticed a smell like an electric motor burning. Backed out of my space to drive home and the car displayed several error messages- Check electric vehicle system, turtle mode, power reduced. I was stranded and had to order a tow truck to be towed to the dealer and get a ride home.

Repeated failed attempts to repair ICCU culminating in ICCU failure. May 15, 2024 – Initial repair attempt (ICCU-related recall/service). September 5, 2024 – VCMS logic recall performed. December 19, 2024 –second repair attempt for ICCU-related issue. October 16, 2025 – Limp-home logic recall performed. March 11, 2026- Vehicle experienced a complete loss of power and was rendered undrivable. Repeated attempts to avoid ICCU failure still resulted in said ICCU failure and a loss of propulsion event while vehicle was on the road.

I was driving 40mph and received a yellow error message along the lines of "electrical system issue, please check" and my speed was limited to 25mph. After trying to get the car to a safe location (as I was on a narrow two-lane road), the error changed to a blinking red error and my speed was further limited to 12mph. I was unable to get the car one mile to the dealer for service, so I stopped the car in a parking lot and had it towed to the dealer. The dealer diagnosed the problem and replaced the ICCU (2nd time on this car) and the 12 volt battery.

My (EV6) failed to charge on both Level 1 and Level 2 charging. A “Check Electrical Vehicle System” message appeared on my dashboard. I took my vehicle to my nearest dealership, where the technician confirmed a faulty ICCU. Fortunately, my vehicle was drivable, and this failure occurred at home rather than on the highway, which could have been a significantly more serious issue. A part has been ordered, and the vehicle has been in the shop going on two weeks.
