I'm still under the so-called bumper to bumper warranty. My running board cracked in the cold weather (its hard plastic). Ford would not replace it under it's warranty, because it's not included, as well as a long list of other things such as: mirrors, moldings, door handles etc....
In short, it's not really a bumper to bumper warranty, its an outright lie
and they are deceiving most folks. If the problem is not mechanical, they don't want to hear it, and you'll pay for the repair. It cost me $600.00 for a new running board. Good Luck, with your warranty.
