Example complaints

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

“The first problem part is the airbag. The clockspring was fixed twice under warranty. Then the dealership said they wont keep doing it and blamed me wrongly. I had a private mechanic repair the same part twice due to the code it was giving but it turns out thats not what's wrong with it. The entire airbag and electrical components are bad, that is why the two repairs the dealership as well as the private mechanic made did not work. We also have some engine problems they wont continue to fix because my warranty is now surpassed. …”

NHTSA complaint #11727159, filed 2026-03

“Took my car in as the airbag light on the dashboard kept turning on and off— with or without a passenger in the seat. The dealership ran a diagnostic inspection and turns out that the passenger side OCS Mat and ECU are faulty and need to be replaced (DTC codes B176700 and B17672F). I have not been in a crash and there are no obvious signs of damage to the seat that might have caused this. There’s no active recall for this but it does seem that one other person has reported issues with the passenger airbag system and I know other Kia models have had recalls in the past. …”

NHTSA complaint #11727369, filed 2026-03

“Auto theft alarm listed as standard. There is NO THEFT DETECTION AT ALL. There is only a bogus flashing led that does nothing when parked. This is fraud.”
