We were involved in a motor vehicle accident on i-79 in pennsylvania where we were struck from the rear we were stopped in traffic the impact was severe it knocked the rear tire completely off. there was smoke coming in the vents of the front of the car and the air bags did not deploy. the front passenger seat belts tighten up so much that it caused bruising on my chest and ribs. my car was totaled out beyond repair. i do not understand why there was smoke coming from the front and the air bags did not deploy. upon our return home i received an email from diagnostic indicating there was a serious issue with the frontal air bags. i am being told there is no recalls on my vehicle this is concerning to me what if someone else is rear ended and the air bags fail causing death or injury. i believe my vehicle is defective and i don't know what to do.
