I was merging onto the interstate going approximately 35 mph, I spun out on black ice across three lanes of traffic and smashed into the guard rail. The airbags DID NOT deploy during this accident, even when the car rolled back and hit the wall again. Since the airbags did not deploy, I suffered trauma to my chin and inside my mouth. I have facial cellulitis, and I needed to receive 3 stitches inside my mouth to stop the bleeding. This happened because my face hit the steering wheel, rather than being protected by the airbag. There were no warning lights on the vehicle prior to failure. The airbags not deploying could have potentially injured me greatly if I had been going any faster.
