   On [XXX] while traveling to NJ, the vehicle displayed "check electrical system" and would not accept a charge. With only 40 miles of range remaining, I drove the vehicle to Jack Daniels KIA. It is STILL at the dealership, and neither the dealer nor KIA Corp has provided a date that the car will be repaired. The dealer told me that it is covered under the 100kmi powertrain warranty, but that KIA corp must direct how and what to fix. They continue to supposedly try different…

   Vehicle would not start/drive. Vehicle was parked in garage at time of failure. Kia dealership said the ICCU needed to be replaced along with the 12V battery. Prior to the failure, audio was not working in the car for several weeks. Kia stated that was due to the ICCU issues and that the 12V was most likely also failing due to the ICCU. ICCU was covered by KIA, but owner of the vehicle had to pay for the replacement of the 12V battery. Vehicle was inspected by manufacturer…

   This make/model has a known ICCU issue. Ours went out just after warranty expired and the cost is $4,000. The EU and some Asian countries have extended the warranty of this fault due to how prevalent it is.

   I was unable to charge this electric vehicle which I normally do almost once or twice a week using my home level 2 charger. It also did not speak the message that "your vehicle is being charged" which it normally does when I charge the vehicle. I tried multiple times. Then I got into the vehicle and saw that it was giving me the following error messages (pics included below) upon trying to start it. 1. "Check Electric Vehicle System" 2. "Battery Discharge Warning - Please…

   While driving the vehicle a short distance, I heard a loud pop from the back seat. The car immediately warned of an electrical system failure. The issue and symptoms are consistent with ICCU module failures, reported across the kia/hyundai egmp platform. My safety was put risk, because I was stopped in heavy traffic when this happened and could have been stranded far from home with no ability to drive the vehicle more than a couple of miles at most. The warnings started…

   ICCU unit lost power and the car was unable to drive. Luckily I was parked when it happened but if I had been driving it would have been very dangerous. The part was replaced under warranty but they said it could happen again which really scares me.

   The ICCU system in my 2022 Kia EV6 failed for the SECOND time on the highway. The car threw an error telling me to "Check the electrical system" and "Pull over safely immediately" or something similar. Had I not made it to the shoulder, I would have been completely stranded in the middle of the highway, creating an incredibly dangerous situation. This is the second time this has happened with my EV6 in less than 50,000 miles on this car. I had to call a tow truck. I…

    I completed recall in March of 2025 for the ICCU, it failed driving down a busy road in January 2026. Kia did complete the repairs, but only warranties for 12k miles. It seems from forums I am in that this is a common problem. It also caused me to be without transportation for several weeks

    This electric vehicle failed to charge at level 2 charger at home. It charged at level 3 fast chargers however it registered a full charge at 125 miles and the level of charge in % and miles remaining fluctuated with sudden shifts. There were no warning lights or other signs of problems. I took it to the dealership who wanted me to keep driving and wait a week for an appointment. I knew that this could indicate an ICCU failure for the second time and insisted. Also asked…

    Car lost all power and came to a stop while backing out of a driveway on a residential street. It would not respond to any attempts to start it. None of assessories worked. It had to be towed to the dealership. The dealer said the 12v battery was at fault and had to be ordered from Kia. I was told the ICCU unit had failed and drained the 12v battery. It waited for the part from Kia. Then the ICCU needed to be replaced. This was in 2024. The part was not examined. There were…
