Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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.
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.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
ICCU failed after 49,059 miles. Levels 1&2 charging do not work. I must use DCFC to charge the car.
The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
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.

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.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The contact owns a 2022 Kia EV6. The contact stated that while driving approximately 64 MPH, the left side of the steering wheel seized, and the vehicle aggressively jerked to the left into oncoming traffic. The message “Smart Cruise Disabled” was displayed. The contact was able to quickly regain control of the vehicle. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 65,300.
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.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.

I am reporting a recurring safety and reliability issue with my 2022 Kia EV6 GT-Line (VIN: [XXX] ). The vehicle currently has approximately 63,100 miles. The vehicle repeatedly displays a “Check Electric Vehicle System” warning message. This problem has occurred three separate times. On at least two occasions, the vehicle became undriveable and required towing. The failure appears to affect the vehicle’s electric powertrain or control systems. The vehicle is currently being taken again to the dealership (Lou Sobh Kia in Cumming, Georgia) for diagnosis of the same issue. This will be the third service visit for this recurring failure. Because this issue can cause the vehicle to become unexpectedly inoperable, I am concerned about the safety implications and believe it may indicate a broader defect affecting Kia EV6 vehicles.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
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.
While braking in parking lot with low speed and turning the steering wheel, all of sudden the vehicle reving up by itself and then accelerate forward uncontrollably.
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
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.

MY DRIVERSIDE FRONT DOOR WON'T OPEN, WHEN DOOR IS UNLOCKED, BOTH OUTSIDE AND INSIDE HANDLE WONT'T OPEN THE DOOR. YOU HAVE TO CLICK ON THE UNLOCK/LOCK BUTTON 15-20 TIMES TO GET THE DOOR OPEN. ALL THE OTHER 3 DOORS WORKS FINE.
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
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.
While driving at normal road speeds, the vehicle suddenly lost all electronics (infotainment, air conditioning, dash). After 2-3 minutes these systems came back online but the car continued to have a warning light for the Lane Keeping system not functioning. This warning now comes on periodically after this incident
Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
The defogger system. The car window’s suddenly fog up while driving and not adjusting the system. Theres no warning the windows start fogging up. I adjust to just front defrost on high and it takes 10 to 15 seconds to clear the windows good enough to see clearly . I took it to the dealership and was told nothing was detected. Mechanic told me he turned it up to 85, my cars high setting is 82, and tested the air temperature stating it was up to 105°. This just started after the latest recall was completed by the dealership. I’ve attached pictures of the windows fogged up while the system was on auto. This had happened 3 times since the first incident with the system off auto as well.
While driving at night under raining conditions with the auto highbeam enable the Kia’s HUD will get so bright at times that will white out the drivers view making nearly impossible to see. Kia’s is refusing the fix the issue because they can’t replicated even with a video I provided and I even found another persons video on YouTube, as well as several owners on a forum complaining about it.

Interior & seats

Iccu failure and defective drivers seat. Was covered under warranty but took over a year to finish all defective parts. Still not 100%
The air bag (SRS) floor wire harness running directly under the moving front driver and passenger seats are assembled with no shielding or protection. So they are subject to being severed or damaged, and the wires are at risk of corrosion if exposed to moisture or road salt. This is clearly a preventable safety issue. However, Kia and Hyundai are not providing warranty coverage. And replacement of a damaged harness is ~$9,300+ because the harness apparently routs behind the dashboard and to the engine compartment.

I was involved in a fatal head-on collision with a pedestrian while driving my Kia EV6. What component or system failed or malfunctioned, and is it available for inspection upon request? Forward Collision-Avoidance Assist : The FCA system appears to have completely failed. It did not detect the pedestrian, did not provide any audible or visual warnings, and did not initiate automatic emergency braking prior to the collision. Airbag System: The system failed to deploy despite a severe head-on collision. Regarding availability for inspection: The car was impounded by the SDPD and was inspected by both the police and State Farm before being sold to SF after being rendered a total loss. How was your safety or the safety of others put at risk? My Safety: The failure of the airbags to deploy put me at significant risk of serious injury or death in the severe head-on collision. The Safety of Others: While the primary consequence of the FCA failure was the tragic impact with the pedestrian, the malfunction of a safety system designed to prevent or mitigate collisions inherently puts all potential road users at risk. Had the FCA functioned correctly, the collision might have been avoided entirely or the impact speed significantly reduced, potentially altering the outcome for the pedestrian. Has the problem been reproduced or confirmed by a dealer or independent service center? No not to my knowledge. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? As mentioned above, the car was impounded by the SDPD and was fully inspected by both the police and State Farm. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None.
