   I own a 2025 Kia EV6 Wind RWD. At approximately 14,655 miles, the vehicle experienced a confirmed Integrated Charging Control Unit (ICCU) failure that resulted in loss of 12-volt charging and reduced motive power. On August 1, 2026, while reversing the vehicle, I heard a loud pop from underneath the rear seating area. Immediately afterward, the red 12-volt battery warning light illuminated and the vehicle displayed a “Check Electrical Vehicle System” message. Because I was…

   The door closed sensor fails intermittently. This causes the car to sound an alarm while driving, prevents locking of the doors, and results in automated sudden braking at low speeds, such as in heavy stop & go traffic, causing a significant crash hazard. When it engages in the emergency braking routine, it shifts out of gear, so you can’t prevent a rear collision by simply accelerating, you must rapidly shift the car into gear, first.

   As I was driving, there was a loud pop that came from the rear of the car. The vehicle immediately flashed a warning to “check electrical systems”. I pulled over as quickly as possible but was faced with reduced acceleration. I ended up stuck in a parking lot awaiting a tow truck for over an hour with my dog and my wife in the car headed to a surgery appointment. The dealership has not confirmed anything but from research it seems to be a known issue that Kia has not…

   While driving Friday 4/17/26, I heard a pop and the car displayed a message to "Check electric vehicle system." The car seemed to still drive so I drive it home. That evening the car would not charge. I called Jim Shorkey Kia on 4/18/26, where I bought the car, to schedule the car to be looked at. They told me to bring it in on Monday and they will try to squeeze me in so they can diagnose the issue. Later that morning, I took that car out and made it about a block away…

    While driving on a sunny day on a 35mph road, my dashboard reported “Check Electrical Vehicle System”. A red battery symbol appeared and my cruise control disengaged with a message “requirements not met”. When I got home I read my 12 volt battery monitor that reported the battery was 11.99v and only had a 60% state of charge. Just prior to this short drive from home, my battery was 12.77v and had a 100% state of charge. I put in my ODB reader and it provided two error codes:…

    ICCU failure. Car lost power while driving. I heard a "pop" sound and then the car displayed a warning light moments before losing power. Car was towed to the dealership where they diagnosed and replaced the ICCU and a fuse. This is a known problem since the 2022 model year and seems to be a very common failure that the manufacturer is unable definitively repair. Thankfully I was on a local street and not on a highspeed highway when this occurred.
