After sliding into a ditch, my drivers side, curtain airbag deployed but, instead of covering the drivers side door window, it came out and went across my face, hitting me on the right side of my head, slamming my head into the drivers side window glass and pinning me between the airbag and the window glass, obviously putting my safety at risk. I am currently being treated for neck injuries as a result of this airbag malfunction. The problem has not been reproduced/confirmed by dealer/independent service center. The vehicle has not been inspected by anyone. Photos of the vehicle including the airbags have been sent to my insurance company (Allstate). There were no warnings or symptoms of the problem prior to the collision and no other vehicles were involved. Upon visual inspection, both the driver and passenger side curtain airbags are twisted around itself 4 or 5 times at the anchor point, located at the front of the door frame. The vehicle is currently in our shop at our residence.
