A woman was involved in a 40 MPH collision caused by another driver. Her airbag went off, and she recalls seeing black smoke. Her hands were blown off of the steering wheel by the airbag. She didn't get treatment after the accident but, once the adrenaline wore off, later went to the doctor. She has chest pain and is coughing up thick mucus.
Her husband says that airbag smoke should be white, not black. Is it possible that her airbag malfunctioned? It was a Takata airbag and had been recalled, but she hadn't taken the car in to have the airbag replaced at the time the accident occurred.
