Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My electrical system failed. While on park I was unable to shut of the vehicle using the engine start stop button. After waiting for the vehicle to automatically turn off. The vehicle started trying to restart itself. The negative battery post had to be removed for the vehicle to stop. The entire safety system failed and all warning lights are still displayed on the dash. The backup camera and radio display went completely blank and was unavailable.”
NHTSA complaint #11662150, filed 2025-05“My 2021 Kia Sorento X-Line Prestige comes with Driver Assist features. One is for steering. Without warning it will disengage, particularly on a 2-lane highway, or when entering a curve in the road. This is dangerous. It needs to come with a warning that Driver Assist can flake out on 2-lanes and on curves, and is fairly useless unless you are on a straightaway on an interstate. This has happened to me multiple times since I bought the car from the Heiser dealership in Wisconsin.”
NHTSA complaint #11546505, filed 2023-09“The collision alert system is out of wack. The system is at a glitch era where as no cause prompts the alert. I am now responsible to disable all systems prior to each drive to avoid unnecessary automatic braking. The following are of concern: Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning”
