2022 KIA EV6 Complaints

Widely circulated and well known ICCU issue leading to 12v failure. There is a recall on this, but people are being stranded and offered only part replacement. Kia should be responsible for corresponding costs associated with their defective units. I’ve had 2 bad ICCUs and the second one left me stranded. Unacceptable.

I was driving and experience a loss in power and got the Check Electrical Vehicle System error message. As I was trying to get to safe location to stop, I got the Power Limited warning message and lost even more power then got the Stop Vehicle and Check Power Supply warning. I did not have any warning lights prior to this happening. I had my car towed to a KIA dealership for inspection and am waiting for their findings. It was at the KIA dealership 12/22/2025 for the latest safety recall update.

The car stop working with this message "check electric vehicle system" I towed the car to kia service. They told me nee to replace ICCU unit. They replaced it for free, but still didn't have a car for few days. No loaner car offered.

ICCU failed preventing the vehicle from being charged and killing the 12v battery.

I am reporting a failure related to the Integrated Charging Control Unit (ICCU) on my Kia EV6 vehicle. The vehicle suddenly became unable to charge using Level 1 or Level 2 AC chargers. Each time the charging cable is connected, charging starts briefly and then stops within seconds with a “charging unsuccessful” warning. The issue occurs consistently across multiple chargers. However, DC fast charging (Level 3) still functions, indicating a failure specific to the onboard charging system. In addition to the charging failure, the 12-volt battery became abnormally depleted, which required external charging to prevent the vehicle from becoming completely inoperable. This raises safety concerns, as a drained 12-volt battery can disable critical vehicle systems. This appears consistent with widely reported ICCU failures affecting Kia EVs. The failure occurred without warning and has rendered the vehicle unreliable for normal use. Because the vehicle cannot charge at home or on standard public chargers, it creates a safety and mobility risk, especially if the vehicle becomes stranded due to 12-volt system failure. I am concerned that this is a systemic defect in the ICCU that impacts vehicle reliability and safety and should be investigated further.

ICCU failure at 71k miles on 2022 Kia EV6. Owned for 46 months, original owner. 12 volt battery also died when 18 months old, which left me stranded and I had to be towed to dealership Never missed a service or recall update

Unsure exactly why it happened, but I was driving in my parent's neighborhood (25 mph limit), and I heard a pop, and the next thing I saw was an electrical warning message on my dashboard. That's when I realized the issue is with the ICCU.

Heard fuse pop in back of car immediately went into turtle mode with red check electrical system warning. Dealer diagnosed as bad ICCU which also drained the 12v battery. This recall should be left open for all these ICCUs keep failing and stranding people.

I was driving to work less than a mile away from my home, when coming up to a red light my car told me to find a safe place to stop. No previously warnings or other symptoms. Car just went from fine to nonfunctional in a matter of seconds. Once stopped, I had no power or any electronics. Not even hazzard lights. I was stuck at the intersection while I awaited a tow truck which had difficulty getting the car on the truck due to the complete electrical failure. Car was towed to a local Kia dealer who inspected it the next day and confirmed the ICCU was at fault. It was replaced in a couple of days and convered under warranty. 12v battery also dead but not covered by the warranty even though the faulty ICCU could have caused it to die early.

The ICCU failed after having the safety recall done on it. The car went into warning mode and I luckily had just enough time to pull it into a parking lot to get towed. another few minutes I would have been stuck on a road with no where to pull off. The dealer did replace the ICCU and said that they were familiar with the part blowing randomly on people and that Kia is aware but not making good fixes by putting in the same defective replacement units
