New Car Assessment Program
The 2024KIAEV6 carries 77 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 8 crashes, 2 fires, 6 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2024 EV6 is electrical system with 30 filings, followed by power train (11) and unknown or other (8). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 38 investigation files overlapping the 2024 EV6, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY
Kia America, Inc. (Kia) is recalling certain 2022-2024 EV6 vehicles. The Integrated Charging Control Unit (ICCU) may become damaged and stop charging the 12-volt battery, which can result in a loss of drive power.
ELECTRICAL SYSTEM:12V/24V/48V BATTERY
Kia America, Inc. (Kia) is recalling certain 2022-2024 EV6 vehicles. The Integrated Charging Control Unit (ICCU) may become damaged and stop charging the 12-Volt battery, which can result in a loss of drive power.
Vehicle Information: 2024 Kia EV6 (VIN: [XXX] ) Mileage at time of failure: 14,005 Complaint Description: My 2024 Kia EV6 experienced a complete failure of the 12-volt battery system despite the high-voltage traction battery showing approximately 80% state of charge. The vehicle became completely inoperable without warning. The 12-volt battery was fully discharged and the vehicle would not enter READY mode. The vehicle required a jump start to become operational. After being jump started, the 12-volt system did not appear to charge properly, suggesting a failure of the Integrated Charging Control Unit (ICCU), which is responsible for converting high-voltage battery power to maintain the 12-volt battery. This failure created a significant safety concern because: The vehicle became completely disabled without warning. This failure occurred while driving in heavy traffic, it created a hazardous situation. The vehicleâs electrical systems, including safety systems, depend on the 12-

The ICCU failed while I was driving my car on a 50 mph road. Check electrical system warning lights appeared. Maximum speed was reduced to 19mph and my car became a road hazard for other cars on the road. I managed to pull off the road once I found a safe spot. After visiting the Kia dealership, the problem was confirmed as a failed ICCU (Integrated Charging and Control Unit) and replaced under warranty. No problems appeared prior to the failure. Vehicle was required to be towed to the repair facility.

ICCU FAILURE. COMMON ISSUE REPORTED WITH EV6s 2022-2025.
The Integrated Charging Control Unit (ICCU) and High Voltage Fuse failed twice within 100 miles, causing a total loss of motive power while driving. The first failure occurred on Jan 24, 2026 (13,954 miles), and the second on Feb 2, 2026 (approx. 14,000 miles), immediately after the first repair attempt. In both instances, the 12V charging system failed, severing connection to the high-voltage battery and forcing the vehicle into a "limp mode" with reduced speed and steering loss in active traffic, creating a severe collision risk. âThe first authorized manufacturer technician stated that the issue was with the 12v battery and not the ICCU, however the second dealership confirmed that the issue was the ICCU all along, resulting in 17 days out of service. Symptoms included a loud "pop" followed by "Check Electric Vehicle System," "Stop Vehicle and Check Power Supply," and 12V battery warnings. Despite Recall SC327/SC302 procedures, the safety defect persists.
2024 EV6 GT-Line with 13,165 miles suddenly showed multiple faults, including "Check electric vehicle systemâ followed shortly by "Stop vehicle and check power supply". The vehicle almost immediately stopped in the roadway, and my wife (driver) was unable to move the vehicle or even put the vehicle in neutral so the vehicle could be moved. The car is at a Kia dealership for repair who confirmed an ICCU failure. This is an exceptionally dangerous situation.

While operating my 2024 Kia EV6, the vehicle began displaying repeated warnings related to the power system and 12-volt battery. The instrument cluster first showed a âPower limitedâ message, followed shortly by a âStop vehicle and check power supplyâ warning. At the same time, the vehicle indicated that the 12-volt battery was low, despite the high-voltage traction battery being at or near full charge. Shortly thereafter, the 12-volt battery became fully depleted, resulting in a complete loss of low-voltage electrical power. I was unable to electronically unlock the doors, and the vehicle could not be started or shifted into gear. The vehicle became immobilized and inoperable, requiring towing. This failure occurred without warning and created a safety concern, as loss of power could potentially occur while driving or leave occupants stranded and unable to access the vehicle. The vehicle had previously been serviced at a Kia dealership for known power system concerns relate

ICCU failure
ICCU failure
on April 7, 2025, our 2024 Kia EV6 was towed away from our driveway after an ICCU failure the day before. The tow truck driver attempted to jumpstart it with a battery eliminator and he could not. He could not get it shifted into neutral and had to pull it up on the ramp with the back tires stationary, sliding up the ramp. They had it until we got it back just before April 22, and then on that day, it was towed away again because of a 12 V battery failure. If this first computer failure had happened while we were on the highway, we would have lost power in traffic. We were told that the replacement ICCU part which we received was a different model number than the first one, but I have heard on Facebook discussion groups that it is identical and just as likely to have a failure. Our Kia EV6 is a 2024 model, an extended battery version Wind AWD. Both the initial incident on April 6 and the second incident on April 21 happened just outside my garage after just backing the car out of the g

Incident took place 1/31/26. I was pulling into my driveway at approximately 5 mph. Normally, as I approach the wooden driveway gate, sensors would begin to beep and I would be prompted to stop.The car normally would stop itself if a collision was imminent. This did not take place. Instead, the car picked up speed, smashed through the gate proceeded up the driveway, smashed through the garage door and the rear wall of the garage. I was alone and uninjured, but the structure was yellow tagged and there was severe damage to the contents. Airbags were not deployed. The car was towed to Caliber body shop in Santa Monica for repairs to the body. When this has been completed it will be taken to Kia of Santa Monica for analysis of the black box and braking system.

Driving with my wife and [XXX] child, there was a pop sound from under the car, and the car suddenly showed multiple faults, including "Check electric vehicle systemâ, which cleared on their own. I parked and turned the car off and on again and the faults reappeared. I started driving home, and during the drive it showed "Stop vehicle and check power supply" and audibly alarmed. As I was only half a mile from my house on local quiet roads, I made it. A few minutes later, I tried to turn on the car and some displays were off, there was no drive power, the steering wheel did not turn, the door locks were flakey, and I wasn't able to tell if I had shifted into Park or if the parking brake was engaged. When the tow truck arrived, the car was completely unresponsive and there was no way to release the parking brake or shift the car in neutral, so the car was dragged across the pavement and onto the tow truck. The failure was quick and comprehensive and could have easily caused injury. T
