I had a car collision last [XXX] when the car ahead of me made a sudden stop in the [XXX] . I was in the fastest lane when it happened and I was not protected at all because the airbag did not deploy. It resulted to pain due to contusion on my chest wall, pain on my sternum contusion on my right knee and neck strain. My insurance covered for the repair. Hyundai has told me after I asked them to check on the car that they are not going to investigate as to why the airbag did not deploy. I feel very unsafe driving it. I am very traumatized.
