2022 Kia Ev6

I began to drive. The dashboard display read "Check low voltage supply" or something like that and on the opposite side of the display there was a small image that looks like a 12V battery. A moment later the dashboard display changed to read "DO NOT DRIVE." The car was towed to a dealer who reported a "failed ICCU and High Voltage Fuse." The vehicle was towed to a dealership where it is being repaired under warranty. The same parts were replaced on December 26, 2024, that time because the electric vehicle would no longer accept a charge from a 240VAC source, although it continued accept a charge from a high voltage DC source. At that time there was also a software update that was said to correct the defect.

The taillight came loose and every time i take it in to get checked or fixed at the dealer they ignore me, so i went in and tightened my self. there were 4 nuts already off and inside my trunk and there was no loctite on the bolts holding the light on. now the lamp is leaking water into the trunk and the tail light has water inside of it.

Vehicle Safety Complaint My Kia experienced an ICCU (Integrated Charging Control Unit) failure and was at the dealership for approximately two months while awaiting repairs. The ICCU and related components were replaced, and I was told the vehicle had been repaired. However, immediately after I received the vehicle back, the “Check Electric Vehicle System” warning illuminated again. Since that time, the vehicle has continued to experience serious electrical issues. The vehicle has unexpectedly shut off while stopped at red lights and has failed to restart on multiple occasions, leaving me stranded. This creates a significant safety hazard because the vehicle can lose the ability to move while in traffic, placing me and other motorists at risk. I have returned the vehicle to the dealership twice since the ICCU replacement, but the problem has not been resolved. The dealership has been unable to identify or permanently repair the defect. I have been without my vehicle for nearly three months this calendar year due to this issue. More importantly, I no longer feel safe driving the vehicle because I cannot trust that it will remain operational in traffic. I am submitting this complaint because I believe this represents a serious safety defect involving the vehicle’s electrical system and propulsion system. I request that NHTSA investigate this issue to determine whether other Kia owners are experiencing similar failures and whether additional action is warranted to protect consumers.

The front lower air dam and felt underguard detached while driving at highway speed on an interstate. The panel dropped and dragged on the pavement. I secured it with duct tape and zip ties at the roadside in order to drive home. There was no collision and no impact with road debris. The bumper fascia directly above the panel is undamaged, with no deformation and no paint transfer, which is not consistent with an impact and is consistent with failure of the panel's mounting fasteners. The panel shows longitudinal drag scoring on the underside and outward flex-fracture of the mounting clips. The right side detached first and the left side remained held by a single screw. The component is available for inspection on request. There were no warning lamps or messages before the failure. I brought the vehicle to a Kia dealer in [XXX] on XXX, at approximately 40,000 miles and within the 5-year/60,000-mile basic warranty. The dealer's technician identified multiple fractured mounting clips, of which only two remain intact. The dealer declined to submit a warranty claim, citing evidence of impact, and reattached the panel using added screws. The fractured clips were not replaced. The dealer's paperwork records the vehicle as repaired, but the technician verbally advised me to drive carefully because the underlying fastener failure was not corrected and the panel is not held by its designed fasteners. I opened a case with the manufacturer's consumer assistance center on June 9, 2026 (case number XXX) and submitted photographs as requested. I have received no substantive response in six weeks. A body panel that detaches at highway speed and drags on the roadway is a hazard to the vehicle behind it and to my control of the vehicle.

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.

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.

Vehicle would not start/drive. Vehicle was parked in garage at time of failure. Kia dealership said the ICCU needed to be replaced along with the 12V battery. Prior to the failure, audio was not working in the car for several weeks. Kia stated that was due to the ICCU issues and that the 12V was most likely also failing due to the ICCU. ICCU was covered by KIA, but owner of the vehicle had to pay for the replacement of the 12V battery. Vehicle was inspected by manufacturer at the local Kia dealership.

Car lost power and stopped Diagnosed iccu failure Now reporting coolant issue following repair

The Integrated Charging Control Unit (ICCU) failed twice within four weeks. The first failure occurred in March 2026 and was repaired under recall SC327 with a replacement ICCU and fuse. The second failure occurred April 7, 2026, approximately 12 days after pickup. Symptoms: Vehicle failed to charge overnight on Level 1 and Level 2 circuits despite being plugged in. Later that day, while driving, a “Check Electrical System” warning appeared on the dashboard followed by sudden loss of power and acceleration. Vehicle fluctuated between 25-45 mph and could not maintain speed. Vehicle was driven approximately 2.2 miles to the dealership under its own power after warning onset. Safety risk: Sudden loss of power and acceleration while driving created a hazardous condition for myself. Dealer confirmation: The authorized Kia dealer confirmed a DTC for battery overheating and acknowledged the ICCU coolant was not fully topped off after the first replacement, suggesting the recall remedy was incompletely performed. The vehicle has remained at the dealer unrepaired since April 10, 2026. Component available for inspection: Yes, vehicle is currently at the dealership. Recall remedy concern: The SC327 recall remedy did not resolve the ICCU failure. A second failure occurred within two weeks of the repair. The dealer’s subsequent diagnosis of owner-caused undercarriage battery damage is contradicted by their own signed inspection report documenting all undercarriage items as passed with no damage noted

ICCU failed after 49,059 miles. Levels 1&2 charging do not work. I must use DCFC to charge the car.

This make/model has a known ICCU issue. Ours went out just after warranty expired and the cost is 4,000. The EU and some Asian countries have extended the warranty of this fault due to how prevalent it is.

ICCU failure at 16k miles. The ICCU was replaced at the dealership on January, 29th of this year, so it is not available for inspection. The failure tripped a breaker at my home while it was charging possibly indicating a short circuit. The short circuit could have potentioally overheated and caught fire in my home. I took the vehicle to the dealership and they confirmed it was the ICCU and replaced it under warranty. I have a copy of the invoice received after the replacement was installed. I do not know what they did with the old ICCU after it was placed. There was no indication of pending failure that I noticed prior to this incident occuring.
