I have the same issue. It started about 2 1/2 months ago, then earlier this month, it went out for good. Now I have no power steering. When it first started, every time the power steering would go out, my wife would be driving on the interstate above 60 mph. It scared her so much, she pulled over to the side of the interstate and waited for it to reset. We live in Houston, TX, a city known for it's incredible amount of traffic, so this was no small feat for her to pull over. I have placed complaints in to the NHTSB, and am hoping for an answer. We are currently in the process of buying a house, so taking it into the dealership right now is not an option. I am not happy about this, seeing I have 3 Fords in my driveway, and was considering buying another Ford when the need arises, but I don't know about that now.
