Passenger Air-bag igniter's wiring shorted out releasing gas into car. The windows were up and the car was not running. I was sitting in passenger side went to light my cigarette and with no warning at all KABOOM!!! Car exploded catching my hair on fire as well as 2nd and 3rd degree burns on hands and 1st and 2nd degree burns on face. The explosion carried so much force that the doors and back hatch were dented outward making it impossible to shut and lock doors properly. Explosion was so loud the people inside the bar thought a bomb had gone off. This incident was not reproduced or confirmed by a dealer or insurance company due to the fact the car was stolen directly after incident due to the fact that the doors could not shut properly. Prior to this incident no warning lights had gone off to indicate a malfunction in the passenger airbag or the wiring. I guess I was at the wrong place at the wrong time.
