2024 KIA EV6 Complaints

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.

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.

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.

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.

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.

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.

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

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

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.
