2022 KIA EV6 Complaints

Kia 2022 EV6 41,238 miles. The ICCU failed and was towed to KIA dealership. It was covered only because we got the extended warranty. Was at 88% charge, dashboard lit up with the warning “Check electric vehicle system”. Loss of drive power increases the risk of a crash.

Integrated charging control unit (ICCU) failed. While my failure prevents ac charging, the unit is could also fail causing the 12v battery not to charge and the car to power down while driving on the highway. There were no indication of part failure.

While driving at speed, I heard a pop noise from the car. A few seconds later, I received notification to check vehicle electric system. The vehicle slowed down despite my increasing throttle input. I was able to limp to a parking lot where it was flat bed towed. This experience matches a previous issue I had when it was diagnosed with an ICCU failure with the same vehicle.

I am reporting a recurring safety defect. While driving the vehicle the Integrated Charging Control unit (ICCU) failed and caused the vehicle to lose power and stop in the road. I feel strongly that this ICCU issue and subsequent failure should be made into a safety recall. Kia / Hyundai / Genesis all share the same e-gmp platform and utilize an ICCU that fails and leaves motorists in unsafe situations. The ICCU should be recalled and replaced with a unit that works. The current recall remedies are only software updates, and are insufficient to prevent this safety issue and hardware defect, posing ongoing safety risk to drivers and other motorists. The ICCU should be a permanent fix, rather than just software patches that do not fix the issue. My vehicle had all software patches and was up to date, yet those were not sufficient to prevent this hardware defect and safety situation.

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

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.

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.

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.

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.
