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.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Kia K4 verdict →
