2022 KIA EV6 ICCU failure. Car stopped Level 1 and Level 2 charging. Dealer confirmed failure and replaced under warranty. This was the best of the failure modes, we were not stranded and the 12v battery continued to the charged. Thanks.

On Sunday, October 4, 2026, the vehicle lost drive power while I was operating it. At the same time, steering became extremely difficult and the brakes required extraordinary physical force to apply. I had to use all of my strength to safely bring the vehicle to a stop. At that point we were stranded in the #2 lane of travel. This was not a minor inconvenience or an isolated warning light; it was a serious roadway safety event. Had my wife been driving, I do not believe she would have had the physical ability to safely control and stop the vehicle under those conditions.

Component that failed: Vehicle headlight/running light has water penetration and the running lights do not stay on. Additionally there is yellowing of the LED running lights, which is a known defect in the Kia EV6. Safety issue: Running lights reduced night time illumination and made it more difficult to see road. Running lights yellowing are a sign of premature failure. Dealer inspection: Dealer identified problem during a state inspection (light turned off after a few seconds). Vehicle headlights have three issues: 1. Yellowing of LED running lights, 2. Failure of seals allowing water into the headlight unit, 3. Malfunction of the running lights (turns on briefly and then goes out)…

The ICCU, or integrated charge control unit, continually fails on this car. When it fails, the 12V battery rapidly drains and the car goes into turtle mode (25mph max) until the 12 battery drains completely. This has happened 4 times on this car, twice since I purchased it 'certified pre-owned" from a Kia dealership in February 2026. Luckily for me the two times it has failed on me, I was in town and close to home. I purchased this car to use for road trips, and out in remote areas of wilderness that do not have cell reception. It is my opinion that the lack of a permanent fix from Kia is a safety issue, as this problem can strand a driver like myself in the middle of nowhere without cell…

I began to drive. The dashboard display read "Check low voltage supply" or something like that and on the opposite side of the display there was a small image that looks like a 12V battery. A moment later the dashboard display changed to read "DO NOT DRIVE." The car was towed to a dealer who reported a "failed ICCU and High Voltage Fuse." The vehicle was towed to a dealership where it is being repaired under warranty. The same parts were replaced on December 26, 2024, that time because the electric vehicle would no longer accept a charge from a 240VAC source, although it continued accept a charge from a high voltage DC source. At that time there was also a software update that was said to…

Vehicle Safety Complaint My Kia experienced an ICCU (Integrated Charging Control Unit) failure and was at the dealership for approximately two months while awaiting repairs. The ICCU and related components were replaced, and I was told the vehicle had been repaired. However, immediately after I received the vehicle back, the âCheck Electric Vehicle Systemâ warning illuminated again. Since that time, the vehicle has continued to experience serious electrical issues. The vehicle has unexpectedly shut off while stopped at red lights and has failed to restart on multiple occasions, leaving me stranded. This creates a significant safety hazard because the vehicle can lose the ability to move…

The front lower air dam and felt underguard detached while driving at highway speed on an interstate. The panel dropped and dragged on the pavement. I secured it with duct tape and zip ties at the roadside in order to drive home. There was no collision and no impact with road debris. The bumper fascia directly above the panel is undamaged, with no deformation and no paint transfer, which is not consistent with an impact and is consistent with failure of the panel's mounting fasteners. The panel shows longitudinal drag scoring on the underside and outward flex-fracture of the mounting clips. The right side detached first and the left side remained held by a single screw. The component is…
