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,
NHTSA complaint 11767230I 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.
NHTSA complaint 11767188When 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
NHTSA complaint 11763039I 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.
NHTSA complaint 11763034My 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.
NHTSA complaint 11762654Car 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.
NHTSA complaint 11751635Rear 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.
NHTSA complaint 11750683We 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.
NHTSA complaint 11749585Component: 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.
NHTSA complaint 11741641The 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.
NHTSA complaint 11740227Does not ac charge and no codes present
NHTSA complaint 11736865I 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.
NHTSA complaint 117356512024 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
NHTSA complaint 11734168Vehicle 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.
NHTSA complaint 11733902Listing 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
NHTSA complaint 11733307I 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.
NHTSA complaint 11732922The 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.
NHTSA complaint 11732893Went to charge my vehicle in my garage on 4/15/26. When it was fully charged, I reached to disconnect the charger from the vehicle and the connector was hot to the touch; the charging hub on the vehicle was also hot, the charger had a slight plastic burning smell. I immediately tried to contact the company and learned that they had unbeknownst to me, ceased conducting operations in the US. So I ordered a new charger. I also tried it again on 4/17/26; and the heat was higher faster than it was on 4/15/26; so I hav disconnected the device and installed a new one. The electrician noted that the breaker was damaged and had to be replaced. I also recall, that a few months after the initial install of the charger, there was an incident where my wife saw sparks in the garage from the breaker and we heard a large pop; and then the charger went out. The company sent us a new one then that worked fine for a few years.
NHTSA complaint 11732119Issue was diagnosed as ICCU failure.
NHTSA complaint 11731325Known ICCU issue by manufacturer. While driving get alert on screen the check electrical system. Had to pull over and call tow truck for safety reasons. Charging system is not working properly and 12v battery can die at anytime.
NHTSA complaint 11729356Technical service bulletins and other notices the manufacturer sent to dealers. A bulletin is not a recall.
