Example complaints

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

“The warnings on the car all failed and I was lead off the road while going on a roundabout. This has trigged my car to completely lose all control and even though I was attentive to my steering wheel I still didn’t stop the car from leading me to that curb and off road onto grass etc.”

NHTSA complaint #11739853, filed 2026-05

“The airbags failed to go off. I think the vehicle is still available it was towed to Carroll's in Winslow Maine. By the airbags not going off it made the risk of injury much greater. Also lost control of the steering all together. Tried to swerve to miss an animal and the steering assist took over. Yes we have a police report stating that the airbags didn't go off. I am sure budget had their people go look at the car. No warning lights present.”

NHTSA complaint #11684275, filed 2025-09

“I am reporting ongoing safety issues with my Kia K4 LXS involving driver assistance systems and steering control. While driving in heavy rain with reduced visibility, the vehicle disabled multiple sensors and displayed a “camera obscured” message along with inattentive driving warnings, despite both of my hands being on the steering wheel and my full attention on the road. The loss of driver assistance features during hazardous weather conditions created a distracting and dangerous situation. This issue occurs frequently. …”

“While driving on the freeway in the left lane on a two-lane highway, the lane departure and steer ahead feature incorrectly adjusted steering and pulled vehicle into the right lane.
