A month ago I rear ended somebody. I take full responsibility for this. However the crash alert did not go off. Yesterday I was driving down the road in the dark at about 6:00 AM, by myself, nobody else around and the crash alert went off for about two minutes saying that I was about ready to get into a wreck. Ford did look at it two weeks ago, they had one of their techs walk around it make sure that the crash alert would go off and apparently it did.
