2022 Kia EV6 Complaints

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) Manufacturer included replaceable desiccant packets in the headlight, which indicates they understood the potential for water penetration/condensation.

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 service or any way to get back. Kia has increased warranty coverage on this component, but has not rolled out a permanent fix. My car has been sitting at a dealership service department for 4 weeks now, waiting for Kia to approve the warranty work. This is a known issue, Kia has increased warranty...

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 correct the defect.

The taillight came loose and every time i take it in to get checked or fixed at the dealer they ignore me, so i went in and tightened my self. there were 4 nuts already off and inside my trunk and there was no loctite on the bolts holding the light on. now the lamp is leaking water into the trunk and the tail light has water inside of it.

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 “Check Electric Vehicle System” 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 while in traffic, placing me and other motorists at risk. I have returned the vehicle to the dealership twice since the ICCU replacement, but the problem has not been resolved. The dealership has been unable to identify or permanently repair the defect. I have been without my vehicle for nearly thr...
