Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The vehicle consistently pulls sharply to the right while driving, creating a serious safety hazard. As soon as I release the steering wheel, the car veers aggressively to the right, making it difficult to stay in the lane. The steering wheel does not center and requires constant correction. The issue feels mechanical and significantly impacts my ability to drive safely.”
NHTSA complaint #11660607, filed 2025-05“The reverse braking feature registers cross traffic or movement that is not near the back of the vehicle. This cause the braking system to engage. I was doing a U turn on 4 lane main street with a center divider. I didnt fully clear the turn leaving me to reverse to complete to turn. When i put the car in reverse, the sensors picked up movement across the street, engaging the brakes and leaving me stuck in the middle of the road with oncoming traffic coming straight at me. …”
NHTSA complaint #11680278, filed 2025-08“Check engine light came on and when filling up my gas tank, gas spit back out at me which has happened with the fuel tank i had in it last year and has since been replaced. Forward collision, EBS, traction control and forward safety sensor lights came on the next day and the car is running extremely rough. It was towed to a shop to see if it has to do with the fuel tank recall. Multiple people in Roanoke, Virginia are having the exact same problem as is a large portion of people online complaining about the exact same thing. Some going back 30 weeks ago.”
NHTSA complaint #11677076, filed 2025-07“I was driving 35 mph with nobody in front of or behind me and the car slammed on automatic braking for no reason, stopping me in the middle of the road.”
NHTSA complaint #11432865, filed 2021-09“Vehicle will occasionally fail to properly initialize its safety systems, causing ABS, Traction Control, FCW, warning, auto stop, auto hold lights to come on and the aforementioned systems to fail. This disables driver assist features and important safety systems. Kia Dealer does not attempt to resolve. Claims that “we parked too close to a tree and the vehicle thinks it was in an accident” would like further investigation from Kia to be performed regarding this issue.”
