   The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.

   My car was / is one of thousands of Kia cars based on the eGMP platform to experience an ICCU failure. This is believed to be a design issue. While the repair was covered, reports indicate that the problem is not solved and will re-occur in time.

   When attempting to level one charge the vehicle at home, the car returned a failure to charge error and would not charge. This was attempted several times using different outlets and the same error occurred. The car was brought to Gettel Kia in Bradenton Florida. The dealership confirmed that the ICCU had failed,. They did not have the part and apparently it is on backorder. The repair is being covered under warranty, however, it is not being considered a recall, despite…

   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…

   While driving in traffic I heard a pop, then the "Check Electric Vehicle System" warning came on the dashboard. After a minute or so the dash warning changed to "Stop Vehicle" and the car limped home but at a lower speed. This matched the description I had seen of ICCU failures on Kia and Hyundai EVs. Dealer confirmed this was in fact the issue, and I had it replaced under warranty. This was a safety issue for me and my family because when it failed I was driving in traffic…

   While driving at speed, I heard a pop noise from the car. A few seconds later, I received notification to check vehicle electric system. The vehicle slowed down despite my increasing throttle input. I was able to limp to a parking lot where it was flat bed towed. This experience matches a previous issue I had when it was diagnosed with an ICCU failure with the same vehicle.

   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…

    Bought this car in 2022 and had no problems until 1/2/26. Car was charging at home and suddenly stopped. Got a check electrical system warning light. Took it to the dealer to get checked out and the ICCU needs to be replaced. Despite everything online saying that it is covered on the 10 year/100,000 EV warranty, they are denying that it is covered under warranty. They say it is covered by the basic 60,000 mile warranty which I am a whopping 8,000. There has been multiple…
