2024 Kia EV6 Complaints

POWER TRAIN,ELECTRICAL SYSTEM — Filed 10/12/2026

Something with the electrical system in this electric vehicle was not functioning properly as the car would go into "turtle mode" as the service department called it. 45 mph then dropping to 30 mph before reaching the dealership. My safety was at risk because driving on the highway could have had someone rear end up by slowing down. The dealership has been inspected. Waiting at the dealership since Monday Oct 12, 2026. I don't think my vehicle has been inspected by the manufacturer, police, or insurance representatives. Vehicle would warn to check the battery system at car start. Upon driving the car will notify and show a battery red light on the dashboard. The notification will say to stop and check the electrical system.

ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,ENGINE — Filed 09/26/2026

Dear Kia Customer Care, I am writing to formally report a serious and recurring safety issue with my Kia vehicle. I have repeatedly experienced a "Power Limited" error while driving, often accompanied by a turtle icon and a "Check Electric Vehicle System" warning. On multiple occasions, the vehicle has suddenly lost power and stalled in the middle of the road. This is extremely dangerous and has put me and other drivers at risk. A vehicle should never lose propulsion unexpectedly, especially in active traffic conditions. I request an immediate investigation into this issue, along with a clear explanation of the cause and a permanent fix. Please treat this matter with urgency, as it directly concerns driver safety. Kindly confirm the next steps and the earliest available service appointment. Thank you,

I was driving my car on the highway, then I got the message çheck your electrical system'for around a minute. Then there was a rumble or bang as if I hit something with the back, but the road was clean. Then the car started slowing down and I drove to the side. I got out of the car and saw white smoke coming from under the car in the back. I started opening the hood and trunk in the back to find out, where the smoke came from. It was nothing to see. Because it was an electrical car I assumed, that it could start burning, when it smells like smoke and looks like smoke. So I called 911 and told them, that I think my electric car is starting to burn, where I am and that nobody was injured. I took everything out of the car, closed the hood, the trunk and the doors and moved in a safe distance at the side. Around 10 minutes later firefighters arrived and started to put out the fire with a water hose. They opened the trunk, removed the covers there and put water an top of the burned part. The fire wasn't that big. I think, I acted fast enough, to stop it early. I think the battery started to burn. Nothing else was affected. The police called a towing truck and the car is now at the towing yard. It happend 3 hours ago. Police came, I have a filenumber and the insurance has also been informed. I took some pictures of the small fire, the smoke and the melted parts in the trunk after the fire was stopped.

STEERING,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 09/08/2026

I got into my car in a hurry i put my car in drive as i was closing my driver's door and took off and because the door wasn't fully closed the parking brake engaged itself but the power over comes the parking brake, when i let off the throttle the rear wheels locked up causing the car to slide out of control. I pushed on the throttle again to unlock the rear wheels causing me to swerve in the other lane and almost crash into an incoming car. I tried to turn off the brake and could not without stopping the car so i had to skid out of control again stopping to turn it off.

SEAT BELTS,SEATS — Filed 09/01/2026

When putting a car seat in and using the cars seat belt the rear seat belt buckles do not come up at a high enough angle and cause the belt to bind in the buckle for the lap and will not allow the belt to slide and be properly tensioned to hills the car seat to the bottom of the cars seat

ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM — Filed 09/08/2026

My 2024 Kia EV6 is experiencing a total failure of the 12V charging system and requires manual jumpstarts to operate. The official ICCU safety recall (SC327) was previously performed, which is why the NHTSA database shows 0 unrepaired recalls for this VIN. However, the manufacturer's remedy has completely failed. Per NHTSA safety guidelines, this vehicle is currently subject to a sudden loss of motive power while driving and is unsafe to operate on public roads.

ELECTRICAL SYSTEM — Filed 07/16/2026

Car was totally dead even with a 68% charge. AAA came out to jump start. The next day while driving on the highway the car started to lose power. A red warning to check the electrical system came on along with "turtle mode". I was able to pull over off the highway, grateful the two small children were not with me. Car was towed to dealer who kept it for the three days. Only after repeated calling could I reach someone who said they couldn't reproduce the problem. I'm afraid to drive the car at this point as I feel it's just unsafe to do so. This seems to be an ongoing issue that Kia can't seem to fix.

WHEELS — Filed 06/10/2026

Rear tires on my 2024 Kia EV6 wore down to the tire wear-bar limit (2/32" remaining tread) at approximately 19,500 miles, while the front tires on the same vehicle measured roughly double that remaining tread (4/32") at the same odometer reading. The factory-installed tires are rated by the manufacturer for approximately 50,000 miles of tread life under normal use, so reaching the wear-out point on the rear tires alone at roughly 39% of that rated mileage is well outside expected wear for this vehicle at this mileage. This is not an isolated event: numerous other EV6 owners have independently reported the same front-to-rear wear disparity and premature rear tire wear online, across different driving styles and regions, which points to a vehicle characteristic (front/rear torque split, alignment or camber specification, or suspension geometry) rather than individual driver behavior. Uneven, accelerated rear tire wear reduces traction and increases stopping distance, and raises the risk of hydroplaning, tread separation, or blowout, particularly in wet weather, since the rear tires lose effective grip well before the front tires or before a typical maintenance interval would flag it. The wear was confirmed and documented, including tread-depth measurements at all four corners, by an independent third-party vehicle condition inspection performed at lease return. There were no dashboard warning lights or driver-facing alerts indicating the wear; it was only discovered through physical tread-depth measurement at that inspection. The tires inspection results are available upon request. This appears to reflect a design or specification issue affecting the vehicle's rear tires disproportionately, rather than a manufacturing defect isolated to one tire.

ELECTRICAL SYSTEM — Filed 06/06/2026

We purchased a certified pre-owned 2024 Kia EV6 GT on 6/5/2026. On 6/6/2026 while driving on city streets, the display screen suddenly displayed a large and flashing red warning message "Stop vehicle and check power supply" in addition to the battery symbol. We took the vehicle to the dealership and they diagnosed that the ICCU had failed and needed to be replaced.

ELECTRICAL SYSTEM — Filed 05/29/2026

Component: ELECTRICAL SYSTEM:12V/LOW VOLTAGE BATTERY, PROPULSION system:Integrated Charging Control Unit (ICCU) Description: This vehicle previously had the mandated safety recall software update (Campaign SC327) applied by an authorized Kia dealership in December 2024 to protect the Integrated Charging Control Unit (ICCU). The corporate recall remedy failed. In January 2026, the vehicle suffered a sudden, catastrophic loss of motive power while driving on a public roadway due to a total ICCU failure, which created an immediate hazard for myself and my young child who was inside the vehicle. When the primary ICCU component failed, it starved the low-voltage system, causing severe deep-discharge damage to the 12V battery. Following the warranty repair of the ICCU in February 2026, the vehicle was returned to me. However, Kia's official corporate diagnostic and repair procedures for this defect are fundamentally flawed and incomplete; they do not mandate a comprehensive load-test or automatic replacement of the 12V battery following an ICCU collapse. Because of this failure in the official repair procedures, the vehicle was returned to service with a critically compromised low-voltage system. This directly resulted in recurring battery warning messages over the subsequent months, culminating on May 29, 2026, in a secondary, total 12V battery failure that completely bricked the vehicle. The failure of the manufacturer's official safety recall remedy and the subsequent inadequacy of their post-failure service protocol left this vehicle in a chronically un-roadworthy and unsafe condition.

AIR BAGS,FORWARD COLLISION AVOIDANCE — Filed 05/15/2026

The contact owned a 2024 Kia EV6 and stated that while driving at 40 MPH, an elk suddenly appeared in front of the vehicle, resulting in a head-on collision that completely crushed the front end of the vehicle with no air bags deployed. The front end of the vehicle was crushed including the windshield. The vehicle continued with the elk after collision dragging it a couple yards ahead. The air bags did not apply. No waring lights were illuminated. No police report was filed. The contact was the only passenger during the collision. The contact suffered a sever neck issue and is not able to move his neck to the right, has chest pain and shoulder pain on both sides, and a head injury. Medical treatment is need but has not gotten any due to insurance issues. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 20,000.

ELECTRICAL SYSTEM — Filed 04/12/2026

I had an ICCU failure on 4/12/26. I was fortunate enough to be close to home, so I was able to get back home before the vehicle dropped into reduced power mode. As has been reported many other places, I heard a loud pop and moments later a number or warning messages came up on the display. It was towed to the dealer the following day and has been confirmed to be an ICCU failure.

POWER TRAIN,ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM — Filed 10/27/2025

2024 Kia EV6 leased January 2025. Vehicle is subject to NHTSA Recall 24V-867 / Kia campaign SC327 for the Integrated Charging Control Unit (ICCU). The recall remedy was performed at an authorized Kia dealer in July 2025 (software / operational logic update). The defect was not cured. Three months after the recall remedy was performed, the vehicle suffered complete loss of electrical power and would not move. It was towed to the Kia dealer. The dealer's own diagnostic recorded code P1A9096 — the exact diagnostic code Kia's recall instructs technicians to check for — and replaced the ICCU and high-voltage fuse. This is the recall-defined failure occurring AFTER the recall remedy was applied. Approximately three months later, the vehicle again suffered total loss of power and would not start in cold weather. It was towed in. The dealer replaced only the 12-volt battery and did not address the ICCU, despite the documented prior ICCU failure on this VIN. The 12V battery failure is a known downstream symptom of ICCU failure on this platform. Approximately one month after that, the vehicle returned for charging system failure ("vehicle charges briefly then stops") and a "check electrical/hybrid system" warning that appeared while driving. Diagnosed as charging port failure. Vehicle was out of service approximately 27 consecutive days. Total cumulative days out of service across four visits: approximately 35-40. Two safety-related stranding incidents resulted from these failures. Both occurred in winter conditions in Pennsylvania. In the first, the driver was stranded in a parking lot at night during a snowstorm in sub-zero conditions; three tow trucks were dispatched before a flatbed could recover the vehicle because the EV could not be towed conventionally with no power. In the second, the vehicle died in a school parking lot during a snowstorm; the first dispatched tow truck could not recover an EV with no power, and the driver had to walk multiple miles home in freezing

POWER TRAIN — Filed 03/01/2026

Vehicle display showed a message stating 12 volt battery was low and to pull over immediately, the car the died in a parking lot. I called KIA roadside service and they connected a battery pack to the 12 volt battery and got the car started. This could have been a serious problem if I was on travelling on a public street or highway and suddenly lost power.

Listing as all 3. ICCU/fuse went out, car decelerated to 45 MPH max and flashed a warning to pull over. The bottom left battery indicator for the 12v battery also changed to red, indicating it was not regaining power from the main EV battery. Currently in shop hoping to get part in soon

POWER TRAIN,ELECTRICAL SYSTEM,ENGINE — Filed 01/13/2026

The vehicle’s ICCU unit stopped working out of the blue. This happened on a busy intersection and the car came to a sudden and violent halt. Luckily we were not involved in an accident. It’s a very well known issue with these vehicles and it’s really criminal that Kia has done nothing to fix it. They just change the ICCU unit and then it happens again.

FORWARD COLLISION AVOIDANCE — Filed 02/23/2026

I was backing out of my driveway and backed into a vehicle parked directly behind me. The collision avoidance and emergency braking system should have stopped my car before impact but it did not. No sounds other than the normal backing up beeping. Proximity alert did not ping. The vehicle is available for inspection upon request. The safety feature of collision avoidance and emergency breaking did not work. No, the problem has not been reproduced or confirmed by a dealer or independent service center. No, the vehicle component has not been inspected by the manufacturer, police, insurance representative or other. The police were called to the scene, they just looked at the damage on both vehicles. No warning lamps, messages or other symptoms of the problem prior to the failure. They only appeared once on the day of the accident. I can confirm the backup collision avoidance worked after the incident since the emergency breaking stopped my car in a parking lot after the incident of the failure.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 01/31/2026

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.

UNKNOWN OR OTHER — Filed 09/12/2025

When I stopped the car in a parking lot, before I could engage the parking brake, the vehicle suddenly accelerated and climbed over the curb adjacent to the side walk. Stopped for few seconds and again suddently started accelerating. I could not stop the car as the brake appeared to be disenaged completely and was going all the way to the floor. The car went on the side walk, and descended on the road from the side walk and crossed the road, climbed on the curb again and stopped on the grassy area. Side airbag on the driver side inflated and the drive seatbelt tightened.

UNKNOWN OR OTHER,SERVICE BRAKES — Filed 08/10/2025

Brakes failed with unintened acceleration. We were stopped behind a truck at a stoplight when the the vehicle accelerated with a foot on the brake. We had it towed from the scene of the accident to our local dealership for testing. They had the vehicle for 4 weeks. Kia customer care was not responsive to our calls and emails or the dealerships. The dealership could not confirm the cause without their cooperation. The police were called to the scene of the accident and there is a report. The vehicle has been looked over by the service department at our local Kia lot. It was appraised for cost of damages by the collision center.

[XXX] about [XXX] our 2024 Kia EV6 WIND RWD AUTO VIN: [XXX] already serviced in both NHTSA Campaign #: 24V867000 and Campaign #: 24V200000 had a sudden loss of drive power and nearly all control while driving in rush hour traffic at 65MPH on [XXX] between Atwater and Livingston. The confirmed failed ICCU component can be inspected at Modesto Ca Kia. The sudden loss of drive power and control in rush hour highway traffic put me and numerus other rush hour highway drivers at catastrophic risk of multiple crashes, this could happen to anyone with the same car and especially concerning because our car had ALREADY been serviced in the 2 previous NHTSA recalls (see above) for the very issue (ICCU) that impacted our car nearly resulting in a catastrophic outcome. The confirmed failed ICCU component has only been inspected, and confirmed failed by the KIA EV certified technician at the Modesto Ca Kia dealership. Since owning the car [XXX] a yellow 12 volt battery lamp indicator, not a warning light, on the front dash would occasionally be lit randomly while driving or parked. Just moments before the sudden loss of power and control numerus warning lights and messages were appearing and the displays were flashing on and off. We had absolutely no: warning lamps, messages, symptoms, nor any other issue whatsoever with our car prior to this sudden failure while driving on the highway.

When washing my car at an automated car wash my brakes failed when exiting the facility. When the wash was completed it gave me the approval to leave. I tapped on the gas pedal to get the car moving slowly. The car started to move down the ramp and when I applied the brakes there was no response. I pumped the brakes several times but they did not engage. I tried to hit the parking brake and shift into reverse and nothing happened. I finally had no choice but to hit a wall to keep from hitting a vehicle. I did contact the dealership and they were non responsive. They indicated they had never heard of a wet brake issue on this vehicle. I provided them with several statements from the EV6 Forum. My vehicle had less than 600 miles on the odometer.

I leased a 2024 Kia EV6 on 1/27/24. On 2/22/24, twenty-six days after leasing the vehicle and an odometer reading of 616 miles, while on Washington state highway 903 there was a pop sound, the car slowed, and stopped displaying a “Check electric vehicle system” error. Due to the pop sound, we pulled over and barely made it off to the side of the highway before losing forward momentum. If this happened on a crowded freeway, the vehicle could have been disabled in a traffic lane. After 39 days, the dealer's service department found that inverter was "burnt and charred showing evidence of a fire in the system" and that the fire "potentially damaged the rear drive unit".

ELECTRICAL SYSTEM,STRUCTURE,FORWARD COLLISION AVOIDANCE — Filed 03/21/2024

There are alot of electrical malfunctions including unnecessary and without warning emergency breaking that has injured me ( I temporarily have a rental car to recover from a right thoracic sprain, left hip contusion, and a right anterior chest contusion- I have medical documentation), the steering wheel jerking when no correction needed, the vehicle locking up on the tow truck driver, and a lot of different electrical malfunctions that seem to indicate a bigger problem. I have more evidence, but it would not let me submit more pictures.
