ELECTRICAL SYSTEM, POWER TRAIN
I completed recall in March of 2025 for the ICCU, it failed driving down a busy road in January 2026. Kia did complete the repairs, but only warranties for 12k miles. It seems from forums I am in that this is a common problem. It also caused me to be without transportation for several weeks

ELECTRICAL SYSTEM
This electric vehicle would not charge from a 120VAC or 240VAC source. It would charge using HVDC. It has been repaired by a KIA dealership and therefore the part is not available for inspection. I don't know that anyone's highway safety was at risk because the vehicle continued to operate normally and could be recharged, although not at home. That said, the failure presented as a dead-short to the EVSE, causing the circuit breaker to activate. If the home were improperly wired, I suppose an electrical fire could have occurred. The component that failed and was replaced is the "ICCU," the same component which was subject to a NHTSA recall for failing to maintain 12V power for charging the auxiliary battery and powering the 12V auxiliary equipment. The vehicle was inspected by a KIA dealer and the defective part was replaced. There was no advance warning. One day the vehicle charged normally. The next day, it did not. I am providing this information because NHTSA should have a complete a record of the KIA ICCU failure history as possible.

ELECTRICAL SYSTEM
The car suddenly went into low power mode. It had to be towed to the dealer. The dealer learned the next day that the ICCU failed per the recall. However, while parts arrived a week ago, they do not have sufficient personnel to complete the work. They said it would likely be several more days. I was not offered a loaner. Were I not calling every few days I would not have any information. The dealer has never initiated a call to me for status.

ELECTRICAL SYSTEM
The ICCU stopped working as we were driving on a backroom. The Check Electric Vehicle System" warning light came on, 12V battery discharge, and sudden loss of motor power. If this happened on the highway or while crossing an intersection, there is a high risk of getting hit by another vehicle by the car's sudden deacceleration. The same issue was replicated at the dealership and they are working on a repair or replacing the ICCU.

ELECTRICAL SYSTEM
Electric car stopped working with home, (level 2 or AC charging), only level three or DC fast chargers. Took car to local dealership who confirmed the cars ICCU had gone bad, which is a known issue with this vehicle, and needed to be replaced. Since I had all the software recalls done to mitigate this matter Kia replaced it under warranty. There were no indication that anything was wrong with the vehicle until the first unsuccessful charging attempt at home.

This electric vehicle failed to charge at level 2 charger at home. It charged at level 3 fast chargers however it registered a full charge at 125 miles and the level of charge in % and miles remaining fluctuated with sudden shifts. There were no warning lights or other signs of problems. I took it to the dealership who wanted me to keep driving and wait a week for an appointment. I knew that this could indicate an ICCU failure for the second time and insisted. Also asked that charging port and 12v be tested It was the second ICCU failure which can lead to a dead stop without warning in traffic. This is the second failure in this car.

ELECTRICAL SYSTEM, POWER TRAIN
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

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
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.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
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.
