general problems of the 2000 Cadillac Catera

Passenger side "curtain" airbag in seat went off while my car was stopped and engine not running with no cause or impact while not close to anything in a parking lot.

I got in my car, 2000 Cadillac Catera which was stationary in a parking lot and closed the driver door at the same time reaching back to get seat belt and "bang" an exploding sound. The driver side seat air back exploded, in a parking spot. Causing, lesions, and contusions, on the left arm, and a sprain wrist. Also, scrape and bruising of side, rib area. Also, my boyfriend was in the passenger¿s seat and he suffered an asthma attack from the dust.
