Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Got in my car to leave a store and heard a loud pop and noticed a smell like an electric motor burning. Backed out of my space to drive home and the car displayed several error messages- Check electric vehicle system, turtle mode, power reduced. I was stranded and had to order a tow truck to be towed to the dealer and get a ride home.”

NHTSA complaint #11732104, filed 2026-04

“While driving the car we heard a loud pop in the cabin. That was followed by electrical warning lights on the dash. WE were only about a mile from home and did make it back safely at greatly reduced speed. The ICCU was confirmed to have failed by the dealership. The part was replaced. If we had been traveling on the highway it might have been difficult to find a safe place to exit the roadway.”

“ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an “check electrical” warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.”

NHTSA complaint #11757865, filed 2026-08

“The ICCU has failed twice in my EV6. It is a fairly common issue for this vehicle. I had the ICCU replaced after the first failure, but it has failed again. There was no indication something was wrong with the car until I heard a pop and then the dash indicated Check Electrical System”

NHTSA complaint #11715335, filed 2026-02

“Issues with 12v battery dying with only 8,000 miles on vehicle. Knowing Kia requests an all day testing of the battery prior to replacing the 12v, I replaced it with a higher quality one. My car still did not start not long after that. Lots of folks online with similar issue and feels like Kia needs to do a recall with a known good fix. Blame put on 3rd party apps when it’s a design flaw.”
