I found this forum through a search and saw someone else had posted about the same problem back in November.
I bought this car May 2010, brand new, and now mine is finally doing the same thing:
My car is out of the 36k warranty and I'm working with Ford to see if I can get it replaced without costing $$$.
While I'm waiting to see what they decide, have any of you also had this problem and what did you do about it? And if I get it replaced, what might my options be if it happens again? Ford tells me it's not a safety issue, but it really is kind of a flea under my skin. The car's not two yet (and I'd planned on having it until it was at least 10).
Are there aftermarket things out there I might look into, or a fix I could make myself? Thanks in advance for any help or advice you can give!
