Example complaints

“Hi, I had to transport a few lumber pieces that did not fit into the trunk of my Kia EV6, so I had to leave the hatch open (I pulled it down as far as possible and secured it via a rope against the latch). When I started driving the car started beeping frantically, but allowed me to drive. When I crossed an intersection traffic came to a temporary halt, and when I came to a stop my Kia all of a sudden shut off and would not allow me to put it back into gear again. …”
NHTSA complaint #11752073, filed 2026-07“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.”
NHTSA complaint #11687215, filed 2025-09“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. …”
NHTSA complaint #11716673, filed 2026-02“ICCU failure within three (3) days of buying vehicle. Only 300 miles on it. Failed to charge with known working Level 1 charger on day 1, successfully charged with Level 3 charger on day 2, and then failed to charge at same Level 3 charger on day 3. Simply connecting the Level 3 charger on day 3 had the car emitting charger errors , and then followed that up with an On board charger fault. Vehicle no longer charges. Returned to dealer for repair.”
NHTSA complaint #11723157, filed 2026-03“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.”
