New Car Assessment Program
The 2025KIAEV6 carries 40 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2025 EV6 is electrical system with 18 filings, followed by power train (6) and unknown or other (5). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 38 investigation files overlapping the 2025 EV6, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

I was reversing my car in the parking lot and I heard a pop. Immediately I had a check electrical system warning. Preceding this the car was doing things which may have implied issues with the 12 V battery. Occasionally walking up to the car would not automatically open the car. Or other times, touching the driver handle did not unlock the car. The car is now at the dealership. They have confirmed failure of the HV fuse, ICCU failure, which also blew the 12 v battery. They have ordered the parts but it is currently on back order. The car could drive but after looking up this issue if the 12 v battery had drained it would have been inoperable.
Started my car while I was out and heard a pop sound. Warning message appeared saying "check electrical vehicle system". I was able to drive but when getting onto the freeway, I started to lose acceleration and go into limp mode. I pulled over on the freeway and had to get car towed to dealership. Dealership service center confirmed that my ICCU part failed. The vehicle to my knowledge hasn't been viewed by anyone other than the dealership.
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.
initial filed #11708370 (1/2/2026) 2nd filed #11717025 (2/10/26) Yesterday afternoon (2/10/26), I was told by Jim Shorkey Kia Wexford PA that no error codes are on the EV6, it is ready for pick up. Before I received this call, there was a software update done on the EV6 (see service records) I attached 2 photos of the software update as well. ICCU ASSY was replaced, etc. was told per Shorkey Kia since there are no issues with my EV6, as of Friday when they initially called to say my vehicle was ready for pick up, Kia considers my problem resolved. I know Iâll be paying for the car rental for X number of days, even though the EV6 did not get the software update until this past Tuesday, yesterday 2/10/26, which cleared the 3 codes that were still showing on the Kia app earlier morning yesterday, screenshot of that attached as well. I have my car, no codes visible now.

I have experienced a ICCU failure at 7200 miles on my 2025 EV6 GT Line. This failure is a safety hazard as it will quickly disable the vehicle and strand the occupants wherever they be at the time of failure. (highway, back roads, day or night). There are warning lights when this occurs, but there is a very limited time to get to safety, depending on the state of charge of the onboard 12v battery. This issue has been ongoing since this vehicle came out in 2022. There have been a number of recalls to address the problem, but apparently without success. I see postings all the time with others experiencing this failure. When I inquired about the availability of the replacement ICCU, I was told that the part was on national back order. I was also told there were 147 units in transit, 47 were already spoken for. This seems to indicate that this is a very common issue, affecting many drivers.

11/28/25 on freeway car lost power and would only go 25mph and warning light came on. After short distance full power came back. 12/14/25 earliest appt with dealer and could not find problem. 01/09/26 Lost power and took car to dealer. Dealer said bad battery and they replaced battery. 1/20/25 lost power again and limped to dealer. Dealer found bad ICCU. They are now waiting for new ICCU to replace. When your driving 55 mps on freeway and suddenly drop to 25mph this is dangerous. The apx date required below is when I have taken the car and dealer confirmed ICCU problem not the original problem date of 11/28/25.
ICCU failure at 3889 miles not charging and 12v battery failure
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. This problem could be catastrophic on long road trips.
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.
Was driving home lost all power. Caution lights came on. The ICCU, relay switch, 2 fuses. went bad. It took 9 weeks for KIA to fix, no compensation.
