The ICCU failed. I wasn't able to charge using an AC charger. When I plugged in an AC charger, it tripped the breaker. The dealer replaced it under warranty.
While driving my 2022 Kia EV6 VIN:[[redacted]] my instrument panel screen started to flicker and then within 10 minutes it went completely blank. As a result I was not able to see my speed or battery level creating a safety hazard. I noticed online that this seems to be the same component recalled in newer modes Kias (SC361).

My 2023 Kia EV6 was subject to recall SC327 (NHTSA 24V-867, ICCU); the recall remedy on Nov 19, 2024 was an inspection and software update only. After the remedy, the car repeatedly lost all 12-volt power (Feb 2025 and Apr 2025). Each time, the dealer said it could not find the cause - its hands were tied, it said, because Kia corporate required a diagnostic code and some codes did not yet exist for a car this new - and it repeatedly replaced parts, including the 12V battery twice and the battery sensor, to "hope...

for the best." On May 12, 2026, while driving about 25 mph, I heard a loud pop/bang from under the car, an electrical warning appeared, the vehicle lost power and stopped in traffic, and would not shift out of Park or move. The dealer found the high-voltage box exploded, all high-voltage fuses blown including the 500-amp fuse, the power relay assembly shorted, and connectors damaged by heat; about $16,324 of high-voltage components were replaced under warranty. The dealer and Kia engineering could not determine the cause; the service advisor wrote on July 22, 2026: "We do not have a smoking gun as to what caused all of this... anything is all a guess." On Oct 17, 2026 I found the car completely dead again at the dealership, and it has continued to show electrical faults. After I retrieved the car on Oct 26, 2026, it developed further electrical faults, which I reported to the dealership in writing, including the mirror and remote start failing, false door-unlocked warnings while driving, and two occasions when the car stalled and then recovered. On Nov 2, 2026, the car displayed a charging fault and would not charge at all; the dealership's general manager advised me in writing to discontinue charging attempts until the vehicle is evaluated. The dealership has repeatedly declined to state that the vehicle is safe to drive. I am concerned the vehicle is unsafe and that the recall remedy has not corrected the defect.
Vehicle failed to start and a jump is required to start the vehicle for the first time on 10/6/2026. This has now happened numerous times and at times when the vehicle's power train batteries are charged. An small portable charging device has been purchased to jump the vehicle which eliminates the need to call for roadside assistance. Roadside assistance has take over 2 hour to response. An error on the dash indicated the 12 Volt battery has lost charge. There is a red circle message displayed on the dash. The vehicle was taken to Batteries Plus and a battery and alternator test. No problems were noted. The vehicle is scheduled for a dealer inspection on 10/22/2026.

2022 KIA EV6 ICCU failure. Car stopped Level 1 and Level 2 charging. Dealer confirmed failure and replaced under warranty. This was the best of the failure modes, we were not stranded and the 12v battery continued to the charged. Thanks.
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.
As of Oct2026 2nd occurrence of need by Dealer Service Dept. to replace ICCU in 2025 EV6 Wind; Car delivered new in July 2025 with current mileage of 13,614
On Sunday, October 4, 2026, the vehicle lost drive power while I was operating it. At the same time, steering became extremely difficult and the brakes required extraordinary physical force to apply. I had to use all of my strength to safely bring the vehicle to a stop. At that point we were stranded in the #2 lane of travel. This was not a minor inconvenience or an isolated warning light; it was a serious roadway safety event. Had my wife been driving, I do not believe she would have had the physical ability to safely control and stop the vehicle under those conditions.
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.
The ICCU on the car died in the middle of the street, car would not shift out of park. Car completely died after a few minutes.
The ICCU, or integrated charge control unit, continually fails on this car. When it fails, the 12V battery rapidly drains and the car goes into turtle mode (25mph max) until the 12 battery drains completely. This has happened 4 times on this car, twice since I purchased it 'certified pre-owned" from a Kia dealership in February 2026. Luckily for me the two times it has failed on me, I was in town and close to home. I purchased this car to use for road trips, and out in remote areas of wilderness that do not have...

cell reception. It is my opinion that the lack of a permanent fix from Kia is a safety issue, as this problem can strand a driver like myself in the middle of nowhere without cell service or any way to get back. Kia has increased warranty coverage on this component, but has not rolled out a permanent fix. My car has been sitting at a dealership service department for 4 weeks now, waiting for Kia to approve the warranty work. This is a known issue, Kia has increased warranty coverage on this part, but they are refusing to allow the dealership to perform the work to fix it.
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.
ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an "check electrical" warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.
