Warning Light On problems of the 1997 Mitsubishi Galant

I was slowly backing out of a parking spot at a local shopping center when my steering wheel airbag suddenly and unexpectedly deployed. The force was enough to break my arm. There was no indication of any problem with the airbag prior to this incident, as no warning light or message appeared at any time. Moreover, I had never been involved in any automobile accident with this car prior to this occasion.
