Good luck getting Ford to do anything. Mine was in 2 different shops a total of 5 times and they never fixed the dash rattle.
If it's coming from the instrument panel then it's probably the chromed plastic rings. They are only pressed in and aren't secured or insulated by anything. The good news is you may be able to fix it yourself. Lower the steering wheel as far as it will go and pull on the instrument panel from the bottom. It's not screwed in and will pull right out. Once it's out you can push the chrome rings out from behind by pushing on the tabs. Line the back side of the rings with some 3M double sided padded tape, put them back in and the rattles should be gone.
