In owners' own words
I have received at least two recalls on the ICCU component on my Kia EV6, which were taken to the dealership for repair per the recall. On April 4, 2025, my vehicle displayed the "Check Electric Vehicle Systems" and "Stop vehicle and check power supply" alerts. It had to be towed to the dealership, as it cannot be driven. They called and stated it was related and the part is on back order for the unforeseen future. Electrical system
Rear seat 120 ac voltage outlet indicates an open ground when utilizing an outlet tester. I believe this risks a electrical shock injury to the user. The dealer service department states all is well since a device plugged in powers up. It seams that the dealer service department does not have the requisite knowledge in dealing with household voltages and is not equipped with the appropriate test equipment. Electrical system
ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an âcheck electricalâ warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time. Electrical system
