What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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
Two dealers were notified of the failure in person. The manufacturer was notified of the failure by phone. The failure mileage was approximately 6,000.
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.
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.
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.
Driving on three lane highway at 60 mph the car abruptly lost power. Was able to get off the highway. Called Kia roadside assistance. Tow truck picked up car and delivered it to Kia dealership. Service dept diagnosed and is replacing the ICCU.
2025 KIA EV6 ICCU (part#36401 1XFD5) failed at 2,658 miles. Failure occurred when power was applied after reversing out of a parking space, switching to drive and applying power. No safety issues as vehicle remained controllable. Vehicle went into "limp" mode. Build date of vehicle is 6/20/2025.
It has knocking nosie when turn the wheel, the car had been in the shop for three weeks.
