Driving on a driveway (estimated speed 5-10 mph) when I noted that the driver side door didn't seem completely closed. I tugged on the door handle to shut it and instantaneously felt the driver-side side airbag deploy, scraping my left forearm, left ear, and rupturing the left eardrum. There had been no collision or accident involving the car or any other structure. The vehicle has not been in a prior accident, and has not had additional electric work performed to any of its systems since manufacturing. The vehicle is available for inspection, it has not been inspected yet by a manufacturer or dealer, and the airbag affected my safety by causing physical harm due to faulty deployment.
