2022 Kia EV6 Complaints

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 06/17/2026

1. Severe Safety Concerns (Battery Thermal Risk & Component Interdependency) The PTC (Positive Temperature Coefficient) heater in my vehicle has failed. This component failure has completely disabled my vehicle’s air conditioning (AC) system. In the Kia EV6 architecture, the AC compressor loop is not merely a cabin comfort feature; it is intrinsically linked to the vehicle's thermal management system responsible for cooling the high-voltage traction battery pack. California temperatures are projected to hit 110°F immediately. Without a functioning AC system, the vehicle cannot execute critical battery cooling procedures. Yesterday, when plugging the vehicle into a charger, the high-voltage battery became alarmingly hot. Forcing a lithium-ion battery pack to accept high-current DC fast charging without operational coolant loop heat rejection poses an immediate, catastrophic risk of thermal runaway and vehicle fire. I am terrified to operate, park, or charge this vehicle in upcoming extreme summer conditions. 2. Predatory Maintenance Plan Tie-In Offer Yesterday, the dealership called and acknowledged the issue. They offered to cover 70% of the diagnostic and repair labor costs under corporate goodwill, as I am technically out of the standard warranty period. However, they applied an unfair and coercive condition: I am only eligible for this safety assistance if I purchase a mandatory 2-year maintenance contract costing $120 per month (totaling $2,880 over 24 months). Because the EV6 is a fully electric vehicle, its routine maintenance profile is virtually nonexistent. The dealership explicitly stated that this contract would exclusively cover tire rotations. Charging nearly $3,000 for tire rotations as a gatekeeping mechanism to fix a dangerous battery cooling defect is highly exploitative. The cost of this forced maintenance plan essentially equals or exceeds paying for the entire repair out-of-pocket, rendering the "70% goodwill coverage" an empty gesture.

ICCU failure caused charger circuit breaker to trip due to sudden fault current situation

The contact owns a 2022 Kia EV6. The contact stated that while driving approximately 6-7 MPH in the left-turn lane, the vehicle made an abnormal popping sound and stalled. The vehicle was pushed to the side of the road with assistance. The vehicle failed to restart and was towed to the dealer, where it was diagnosed with Integrated Charging Control Unit (ICCU) failure. The ICCU was replaced, and the vehicle was repaired; however, the failure recurred several times. Additionally, the contact stated that while driving at slow speeds, the messages "Check ABS", "Check ESC", "Check Electronic Parking Brake" and "Pull Over Safely" were displayed, and alarms sounded on several occasions. The vehicle was not repaired. The manufacturer was contacted several times, and a case was filed. The failure mileage was approximately 12,000.

On the night of [XXX], the vehicle was plugged in to AC charge at my home charging at 7.5kw (32 amps/240 volts). The next morning, the dedicated breaker to the EVSE was tripped, and the EVSE was damaged and unusable upon resetting the breaker. The car had charged approximately 20% before cutting off. A new EVSE was ordered and arrived by that night, however the car would not accept a charge, and displayed a "charging failure" message, despite the new EVSE working on two other electric vehicles. Additionally, the vehicle to load (V2L) functionality was compromised, and the vehicle displayed an error message when attempting to use the V2L. The vehicle was taken into Kia service center located in Mission, KS on 6/29, and diagnosed with a broken ICCU, which is scheduled for service on 7/1/2026.

ICCU electrical system failed while driving (~1mi from house). Warning messages popped up and caused me to pull over and drive back to house under reduced speed. Kia told me car was not safe to drive and to tow car for repair under warranty. ICCU failure was confirmed by service provider and repaired after 2 weeks (diagnosis, part order, and replacement).

Vehicle ICCU unit failed resulting in inability to charge at level 1/2 on AC power and would have ultimately led to failure of the 12v battery, which results in the car shutting down. Posing a safety risk. Resulting repair led to coolant level issue. Currently the only solution to the problem is replacement of the unit, with the exact same unit model. Leaving the possibility of it happening again. The manufacturer has not developed a long term solution to the problem, which is common and affects a large percentage of the vehicles. Previous software update recall did not correct the issue.

My car was in my garage and charging with my home's level-2 charger on June 1 2026 in standard fashion. At 2am the charging was interrupted by the car (per charger log) and stopped at 68% charge (set to fully charge to 100%). Subsequently the car could not charge any more, and I tested this with two independent level-2 charging units. Both of these chargers are confirmed operational with another electric car in my garage. I took the car to Kia Service on June 4 and they confirmed it was a failed ICCU.

On [XXX] while traveling to NJ, the vehicle displayed "check electrical system" and would not accept a charge. With only 40 miles of range remaining, I drove the vehicle to Jack Daniels KIA. It is STILL at the dealership, and neither the dealer nor KIA Corp has provided a date that the car will be repaired. The dealer told me that it is covered under the 100kmi powertrain warranty, but that KIA corp must direct how and what to fix. They continue to supposedly try different things to fix the car, but either are not applying resources or are ignorant in how to fix the vehicle. KIA will also not compensate me $1308.99 to cover my current losses (car note, uber to get home when it died, and fuel costs) to date. The car has been out of my possession now for 44 consecutive days straight without any end in sight, compensation, or expected repair date.

Integrated Charging Control Unit (ICCU )failure on the high voltage battery leading to also the 12v battery failure.

ELECTRICAL SYSTEM — Filed 12/19/2024

Lost power while driving. 12Vbattery low voltage on dash. ICCU not responding. Dealership replaced ICCU and told me it wasn't under warranty. Had to pay out of pocket.
