While I was driving my car, all of a sudden my front fender falls off. At first , I thought I had hit something or someone, but my front fender was not dented up , and there were no traces of blood on my fender. I think my airbags would have activated had I hit a car or someone. I got out of my car to see if I hit anyone, there was no one around my car.Miraculously , as I drove my car home , the front part of my fender did not drag under my car. I placed my fender back on the front of my car and it looks as if the car was never hit. I noticed some screws were missing . I know this kind of thing doesn't happen everyday , but is it possible that you can be driving on a road and your front fender suddenly fall down?
