What owners report
Owners of this 2025 Kia EV6 most often describe sudden loss of power while driving, often with a loud pop, a warning to check the electrical system, and a drop to limp mode, and many complaints name a failed integrated charging control unit (ICCU). Other complaints describe charging that fails, long waits at the dealer for repairs, and a few cases of unexpected acceleration or braking. Complaints were filed between September 2025 and October 2026, and mileage is mostly not recorded.
- Electrical system
Sudden power loss, often traced to the ICCU
- 36 complaints (65%)
- typically at 1.4 yrs old
- filed 2025–2026
Owners describe sudden power loss while driving, often with a loud pop, a warning to check the electrical or battery system, and a drop to limp mode at lower speed. Many say the integrated charging control unit (ICCU) was found faulty and replaced, sometimes along with a fuse or the 12-volt battery. According to complaints, the vehicle often had to be towed, and some say the failure happened early in ownership. Where mileage is stated in the text, failures are described from about 300 to about 15,000 miles, and several occurred in the first months of ownership.
What to check: Ask whether the ICCU and 12-volt battery were tested, and whether the 12-volt battery diagnostic software bulletin has been applied. Check the warning messages and the 12-volt battery reading before buying, and ask the dealer for the repair history.
2 excerpts from owner complaints in NHTSA records
“I charged overnight at work. When leaving I heard a loud pop and the check EV system light came one. The vehicle would no longer drive over 40mph. I made it a mile and it dropped to 20mph. The dealership has had my car for over a week. From research it seems to be the ICCU as many others have had problems with.”
NHTSA complaint #11717172, filed 2026-02“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.”
NHTSA complaint #11713640, filed 2026-01 - Electrical system
Long waits for dealer repairs and parts
- 18 complaints (33%)
- typically at 1.4 yrs old
- filed 2025–2026
Owners describe long waits for dealer appointments and repairs, with some cars kept at the dealership for weeks while repairs or parts were pending. Some say the dealer could not find the problem at the first visit, and an owner says the dealer was too backed up to look at the car. In another case the dealer refused to look at the vehicle, and the owner had it checked by an independent shop instead. Mileage is not recorded in these complaints, and the waits followed failures that happened while driving or after a warning message.
What to check: Ask the dealer for the vehicle's repair history, including any ICCU or battery replacement and its date. Ask how long an ICCU repair is expected to take, since complaints describe waits of weeks.
2 excerpts from owner complaints in NHTSA records
“ICCU and fuse failure when it was being moved out from the garage. Got a “Check electrical system” notification when I turned it on following a level 2 charge the night before. It was with the dealer for exactly one month before I was able to pick it back up.”
NHTSA complaint #11730587, filed 2026-04“ICCU failure caused loss of power on interstate. I almost got in a wreck because of this. Kia dealer refused to look at my car. Took vehicle to independent repair shop who diagnosed issue.”
NHTSA complaint #11681042, filed 2025-08 - Electrical system
Charging fails or stops early on AC, DC, or NACS
- 10 complaints (18%)
- typically at 1.4 yrs old
- filed 2026
Owners describe the car not charging at home or on a fast charger, including a NACS port that would not charge at a Tesla Supercharger or at home. Some describe charging that stopped early, a fast charge cut off by a pop and a blown fuse, or a home charge that tripped breakers, and several tie the problem to a failed ICCU. According to complaints, Kia or the dealer identified an ICCU failure in some cases, and new parts could take weeks to arrive. Where mileage is stated, these complaints involve vehicles with about 300 to about 2,300 miles, and charging was described at home, at Level 3 stations, and at a Tesla Supercharger.
What to check: Ask the dealer to test the charge port, the ICCU, and the fuses, and whether the NACS charging error bulletin was checked for the vehicle. Before buying, try a charge at a known working station if possible.

“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. …”
NHTSA complaint #11732744, filed 2026-04“Failure to charge properly on both alternating current and direct current platforms. Trips electrical breakers at residence while charging at home on AC current. The vehicle will only DC fast charge for a few minutes before charge session is prematurely terminated. I have been told by the KIA that it is a failure in the integrated charge control unit (ICCU). They told me there were 47 current problems right now in the state of Tennessee. I have not been issued a recall at this time. The logistics for getting a new ICCU could 2 weeks or greater. …”
NHTSA complaint #11716271, filed 2026-02 - Brakes
Unexpected acceleration or braking events
- 6 complaints (11%)
- typically at 1.4 yrs old
- 1 mention a crash, fire or injury
- filed 2025–2026
Owners describe the car speeding up unexpectedly while pulling into a parking area or garage, and in one case the car kept moving despite braking. Other complaints describe automated braking at low speed in stop-and-go traffic, which an owner links to a door sensor fault, and a slowdown on the highway with ABS and brake system warnings on the dashboard. In one case the owner asked for the vehicle event data to be reviewed. Mileage is not recorded in these complaints, and the events were described at low speed in parking areas or stop-and-go traffic, and at highway speed in one case.
What to check: Ask the dealer to read stored event data and any brake or forward-collision fault codes, and whether any door sensor or brake system update was applied. On a test drive, note whether any brake warning appears during low-speed driving.

“I was driving over to walk my friends dog and I was pulling into the overflow parking area and my car just speed up and it would not stop. I went up a curb and I hit a small tree went down another curb crossed the street and then up another curb and the break would not stop the car. I finally just cut the car off”
NHTSA complaint #11684498, filed 2025-09“While maneuvering my Kia EV6 into my garage, the vehicle accelerated unexpectedly and struck the garage wall. I believe the acceleration may have been unintentional or due to a malfunction. I request review of any vehicle event data”
NHTSA complaint #11738339, filed 2026-05
Buying note. For someone considering this model year, the complaints point to the ICCU and 12-volt charging system as the main areas to check, along with the charging port and the dealer repair history. A pre-purchase inspection should include the warning messages, the 12-volt battery reading, and any stored fault codes, and the buyer should ask whether the related bulletins were applied.

Example complaints
Electrical system: “On 2025-11-12, my car got BMS error P1B9700. On 2025-11-13, I took the car to local Kia dealer. The error is for battery temperature sensor.

No communication from Kia or dealer how to fix this potentionly dangerous battery problem.”

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.

Thankfully I was on a local street and not on a highspeed highway when this occurred.”
