2024 KIA EV6 Complaints

The vehicle’s ICCU unit stopped working out of the blue. This happened on a busy intersection and the car came to a sudden and violent halt. Luckily we were not involved in an accident. It’s a very well known issue with these vehicles and it’s really criminal that Kia has done nothing to fix it. They just change the ICCU unit and then it happens again.

Went to charge my vehicle in my garage on 4/15/26. When it was fully charged, I reached to disconnect the charger from the vehicle and the connector was hot to the touch; the charging hub on the vehicle was also hot, the charger had a slight plastic burning smell. I immediately tried to contact the company and learned that they had unbeknownst to me, ceased conducting operations in the US. So I ordered a new charger. I also tried it again on 4/17/26; and the heat was higher faster than it was on 4/15/26; so I hav disconnected the device and installed a new one. The electrician noted that the breaker was damaged and had to be replaced. I also recall, that a few months after the initial install of the charger, there was an incident where my wife saw sparks in the garage from the breaker and we heard a large pop; and then the charger went out. The company sent us a new one then that worked fine for a few years.

Known ICCU issue by manufacturer. While driving get alert on screen the check electrical system. Had to pull over and call tow truck for safety reasons. Charging system is not working properly and 12v battery can die at anytime.

I had just finished charging the vehicle overnight on a Level 2 charger at a family members home. After leaving the driveway and driving a few hundred feet, an error message showed on the vehicle screen saying "Check Electric Vehicle" system, and then later a second message that said to stop the vehicle. I immediately turned the car around parked it in the driveway again and called roadside assistance to have it towed to the Kia service center. The Kia service center confirmed that it was an ICCU (integrated charging control unit) failure, which they replaced 4-5 days later after ordering the part. These error messages were the first and only indicator of the problem, there were no smaller issues leading up to the issue. Because the failure happened within a block of a family member's home, I was able to get to safety. But it could have been a completely different situation had the failure occurred even a few minutes later when I was on the freeway.

Was backing out of a parking lot space when a loud popping sound was heard from the right rear portion of the car. Shortly after a check electrical system message was displayed and to pull over. Then eventually had a power limited message pop up after 12V battery charging status/condition was checked by roadside service. Would turn out to be the ICCU (Integrated Charging Control Unit) after dealership nearby (Peak Kia) was able to diagnose the problem. Unknown if the failed part is available for inspection. I wouldn't say my safety or others safety was put at immediate risk, but could have been since the car did eventually completely shut down right as I was able to get home only about 1-2 miles away. Vehicle was seen by dealership a few days later and as far as I'm aware are the only entity to do an inspection on the vehicle. No prior warning of any kind before the ICCU failed, and car had complied with all recalls that were supposed to prevent or at least reduce chances of ICCU issues.

After starting the car, a message displayed on dashboard "Check Electrical System." I tried driving the car out of the garage and then a message displayed to the effect of "Stop the car and check battery." I called the dealer and they said to have the car towed to them. After having the car towed to the dealer, they ended up replacing the Integrated Charging Control System (ICCU) and fuse. The danger is that the failure of this ICCU part could cause immediate loss of power when driving. Luckily, that didn't happen to me since I was only creeping slowly out of my garage.

Driving car and then all of the sudden a critical battery alarm appeared and I lost the ability to go above 23 mph. It ended up being the ICCU that needed to be replaced.

Was trying to drive EV. As soon as I pulled out of driveway it gave me a warning sign; to check electrical system/stop vehicle and check power supply. I couldn't drive car anywhere, had to get it towed to dealership. When tow truck arrived we couldn't turn car on, it had no power. Mind you, I had full charge on EV.

* Per paperwork from the car dealer, the ICCU failed along with a 3way valve assembly and a fuse blew. * While driving, the car went into a limp mode greatly limiting its maximum speed. * I was afraid to continue driving it and had the car towed to the KIA dealership. * It took exactly a month for it to be repaired. * The dealership kept the failed parts. * No warning lamps until the failure occurred. * When the failure happened a warning message stated "Check electric vehicle system!" and a battery symbol turned red. *Since it was taking what seemed like a long time for repair, I contacted Kia-Customer-Care and they assigned case number 25902713.

I had just left my house and pulled onto a 5 lane road when the ICCU died. The car lost power while underway. This posed great danger as the vehicle became unable to safely navigate traffic and pull off to safety. Kia is well aware of this hardware problem, tried to fix it with software updates, and deflates the affected number of vehicles. To make matters worse, they tried to deny this was a recall because they claimed the recall was fixed via the software update. This affects every single Kia Hyundai and Genesis EV.
