2024 Kia EV6

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

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.

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.

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.

TECHNICAL SERVICE BULLETIN: PARTIAL REPAIR – ELECTRICAL A/C COMPRESSOR - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information regarding the partial repair of the Air Conditioning (A/C) compressor assembly on some 2011MY~ Optima Hybrid (TF HEV, JF HEV/PHEV), 2015MY~ Soul EV (PS EV), 2017MY~ Niro (DE HEV/PHEV/EV), 2022MY~ EV6 (CV), 2021MY~ Sorento (MQ4 HEV/PHEV), 2023MY~ Sportage (NQ5 HEV/PHEV), and 2023MY~ Niro (SG2 EV/HEV/PHEV) vehicles.

VOLUNTARY SERVICE CAMPAIGN: OWNER NOTIFICATION (SC373A) - This document is the owner notification advising that Kia is conducting a Voluntary Service Campaign on certain 2024-2026 MY EV6 vehicles to replace the 3-way coolant valve assembly with a new one. In addition, dealers will inspect the 3-way coolant valve harness connector for corrosion and, if necessary, replace the harness connector.

TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: 3-WAY COOLANT VALVE REPLACEMENT (SC373) - This bulletin provides information to replace the 3-way coolant valve.
