Was driving around 45mph when I heard a pop noise, like an over pressurized soda bottle popped open. Moments later car abruptly dropped to under 35mph and reported errors and to check battery system. Brought it into dealer and they confirmed my ICCU failed and had to be replaced.

While driving on a busy road at night, my vehicle displayed battery warning lights and went into "limp mode" which slowed me down to 25 mph before stopping completely. I was then stranded until a tow truck could be dispatched. The Kia dealer told me that the issue was an ICCU (integrated charging control unit) which they have to order. I have since learned that this issue is known and is common.

Erratic behavior before pulling out of parking lot: STOP vehicle check power, check 12V battery Stop safely engage parking brake. All dash lights started flashing, going black, power couldn’t be maintained, thankfully not on highway yet. Complete car failure, had to have 2025 EV6 jumped 4 times, battery still showed 41% charged, couldn’t keep charge to even get car in neutral for tow or doors locked. After each jump from tow company, power would last for less than 3-5 seconds, then dead, completely dead vehicle nothing worked.

After 2474 miles, the vehicle Integrated Charging Control Unit (ICCU) failed in my 2025 Kia EV6 making the vehicle undrivable so it had to be towed to the Kia dealer. The ICCU was replaced under warranty. The failure of the ICCU in Kia, Hyundai and Genesis electric vehicles is fairly common and they have yet to come up with a permanent solution.

I was driving on the highway when I heard a pop like a loud fuse sound from the back seat area. Suddenly the car dropped 15 mph from 70 mph to 55 mph and the battery and electrical system warning lights came on and the vehicle said check electrical system. I was able to continue with my hazard lights on to exit the highway, at which point the max speed of the vehicle dropped to 45 mph. It would not go faster no matter how hard I pushed the gas pedal. I was able to pull over to a gas station and park in a spot but the vehicle had to be towed. When the tow truck arrived, the vehicle also flashed with the 12V battery low warning. It was diagnosed as a failed ICCU, which rapidly drained the 12V battery. The car is only 4 months old with about 7,300 miles. This is a serious safety concern, especially with the sudden failure and loss of power. I’m lucky I wasn’t hit and that I was able to get off the road before it totally died.

The rear door of my KIA EV6 intermittently fails to open even when the vehicle is unlocked. The issue has been recorded on video and reported to an authorized KIA dealer, but it has not been repaired. A child safety seat is installed in the rear seat, and this defect creates a serious safety risk in an emergency where immediate access to the child is required. The vehicle is unsafe due to this defect.

Driving down local (residential) roads, the ICCU died; towed to dealership 12/3/2025. All 12 volt electrical was inoperable. So no hazard lights, no shift to neutral, no locking the doors. It was towed to the dealer. ICCU is now being ordered. The Master Warning light and 12V battery warning light illuminated. I was fortunate to be able to park in a parking lot just before all electrical died. An Internet search shows that this is a known issue; and, even after the replacement the situation can happen again. Took delivery 6/28/25. So, not even 6 months old.

Issue Description: When parking facing downhill, I put the car in reverse but the car rolls forward. Feels like the car is either in drive or neutral. Concern is intermittent, and I confirmed each time it happens, gear selector is in reverse. When trying to re-engage reverse, the display shows "gear already selected." Safety risk: Car almost hit car in front of us while trying to reverse. Car was inspected by dealer service center. Could not duplicate, but found an error code. Dealership found multiple software updates available on the brand new car and installed.

Power completely dropped while driving in traffic. This occurred several times. I could have easily been rear ended. Also, I could have been stuck within an intersection, I could have been broadsided. I see researched this issue and found it was widely written about in KIA EV6 online forums. Kia should have checked for issues before I leased the 2025 EV and informed me before I made a decision to lease vehicle. This occured in first weeks I drove the new car.
