2022 KIA EV6 Complaints

Car lost all power and came to a stop while backing out of a driveway on a residential street. It would not respond to any attempts to start it. None of assessories worked. It had to be towed to the dealership. The dealer said the 12v battery was at fault and had to be ordered from Kia. I was told the ICCU unit had failed and drained the 12v battery. It waited for the part from Kia. Then the ICCU needed to be replaced. This was in 2024. The part was not examined. There were no warning signs or symptoms. Had I been in highway traffic my life would have been in danger

ICCU failed while driving on freeway. Heard loud pop which dealership determined to be a blown fuse as a result of the ICCU failing. Car decelerated to 30-40 mph and stayed in this limp mode. Light on dash indicated an electrical system issue. Vehicle was towed to dealership and repair was made under warranty.

On last Feb-2025, Car stopped while driving, message pop up electrical problem, stop the car immediately, it did not have time to properly park, stopped in middle of the road and have to wait 3 hours for tow truck, car wont open or move, all electric dead. (ICCU, fuse and 12V battery replaced) on last week 01/26/26 at 64K miles, message pop up again on screen dash, electrical problem, stop car. i was able to drive at 30mph to dealer and leave the car. after 8 days on lot, i got a call from dealer, ICCU needs to be replaced, not sure when part will be received.

The ICCU went out in my car. Fortunately I was at home charging and not on the road.

Vehicle failed to start (no power). Charged the 12v battery via wall charger and was able to start vehicle but was faced with numerous warnings, including low power mode, electrical errors and other warnings. Car towed to dealership and was found to have a failed ICCU.

The AC charging for this car stopped working around [XXX]. After 3 trips to the dealership for repair I brought it back a 4th time and because the dealership was unable to repair it they gave me a loaner to use while they tried to figure out the problem. During this time they removed the entire battery from the car, dropped the suspension, experienced the car not being able to go into gear (reverse or drive), not hold a charge etc. The car has been 100% inoperable since [XXX]. Today, 01/27/26 the dealership phoned to let me know that a regional Kia technician came by and realized there was just one screw that needed to be tightened and now the car works perfectly and I can come pick up my car and bring the loaner back. There is no way I would ever feel safe driving that car again. Kia America offered me a buy back with the condition that I pay them $9,350 in depreciation.

My 2022 Kia EV6 would not charge on my home Level 2 charger and potentially shorted my ChargePoint home charger due to a failure of the Integrated Charging Control Unit (ICCU). I tried to charge on a Level 1 charger and the vehicle would not charge and brought up a electrical error message. I then tried charging on a Level 3 charger which worked. I brought my vehicle to the dealership today and they confirmed that there is a problem with the ICCU. This is a serious issue that KIA/Hyundai has been aware of for several years and still has not adequately remedied. This failure can occur while driving so it could have caused an accident or left me stranded far from home. KIA/Hyundai should be forced to replace all ICCU units rather than releasing software updates that do not stop the ICCU from failing.

Most vehicles with ABS experience what I call “ABS shudder/jutter” when applying brakes across a road seam where the road surface is uneven or a rut in the road. In this particular case while applying the brakes across a long rut in the road, the “ABS shudder/jutter” was much worse. NOT SPEEDING and having plenty of distance to stop. With brake pedal to the floor several times, the vehicle continued to move forward. The last few feet before colliding with a pickup truck, although the road was completely dry, the vehicle was driving forward yet sliding forward slowly. Felt no different than being on ice. Collision aversion system did nothing to help avoid. There is also only electronic parking brake and not an emergency brake to pull a handle on to assist in stopping. Dealership wasn’t able to find anything simply by driving around and slamming on the brakes and not finding any error codes. Regional technician currently scheduled to be here the 27th of Jan. Several people online have expressed similar concerns, just haven’t hit anything. I feel that the issue lies with the ABS system specifically braking over uneven road seams or ruts in the road and my experience is being discounted.

Repeat failure of iccu/electrical system. Car fails to maintain charge in 12v over time. Something fails damages the charge. I replace the module 6 fuse regularly on my own because I was tired of taking it to dealer and paying ~$20 for a few extra fuses that cost almost nothing. The car was in turtle mode the next day after a trip. The car wouldn’t go more than 15 mph then shut off. You can’t start it to put in neutral to tow so they MUST drag it into the flatbed. You cannot access items to help you from the rear hatch. The car becomes a giant metal paperweight when this issue occurs an leaves you stranded and at risk of harm.

I have had multiple issues with the electrical system in this car. Even after recall and software update the iccu failed. Module 6 fuse consistently blows and I replace myself to keep my car working as close to the way it’s meant to as possible. The 12v battery has failed twice. The last time after a replacement. The system fails to maintain it. When the iccu electrical issue happens the car stops working completely. It is hobbled speeds as low as 15 and cuts off within minutes if you are dealing with this issue. The hatch will not open the car will not go into neutral to be towed so then has to be DRAGGED onto a flatbed to go to the dealership for repair. The repair often takes significant time.
