When I was in a car accident, the airbag exploded. However, the airbag's balloon-like fabric material did not deploy, and a metal part even flew off the steering wheel and exploded, hitting me in the chin. So I lost about half of my lower jaw, most of my lower teeth, and some of my upper teeth. In the process, I underwent a total of three surgeries: emergency, infection, and reconstruction surgery. In the future, I may need to undergo additional implant surgery and additional reconstructive surgery as needed. There has been no formal component inspection by any agency since the accident and there were no relevant warnings or symptoms prior to the accident.
