I hit a deer on a back road coming home from work, on impact I heard a loud explosion and smelt burning electronics and the smell of an air bag, the seat belt locked. Then after the initial impact the car then stopped and the emergency alarm went of and many messages were on the screen. Fast forward after everything, I call onstar to make ask a question they answered with I see your air bags deployed are you okay, I responded yes because "they didn't come out" the air bag switch did explosion but the air bag did not deploy.
