I was hit on the driver side of the car infront of the driver door side of the hood and it took out my wheel and the car is totaled with how hard the hit was made my car bounce but the air bags never deployed and the fireman and the police officer said with as hard as I was hit it should have deployed

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 →
