Our torque sensor needs replacing. McFarland Ford in Exeter said that the torque sensor was repaird via recall at First Ford in Fall River, MA 2014. We have NEVER had a problem with steering. First Ford in Fall River informed me that if we brought the vehicle in for an oil change, any recall item would have been checked, and if they found no problem with it at that time, it was reported, and that ended the recall status for our vehicle. Please, we need your help. My husband is 83; I am 70. This whole thing smells. How can checking something we had no problem with cancel a recall status on our vehicle. There was no warning. Our vehicle worked fine. We got in the next morning, and the steering wheel wouldn't turn.

Crash reported

My power steering light popped on about 6-9 months ago for about 10 seconds and then turned off. About a month ago now, I gently hit a boulder with my front right tire. I dented a couple of steering rods and something else. Got it fixed, and then when the repair guy was backing my car out of their shop, my car just turned on its own. It's the same issue that required a recall of the steering column in this car years ago. (I had it replaced as part of that recall in 2014.) I talked to 3 different Ford dealership parts departments. They all told me the same thing. "Hmm...this is very odd. I've never seen a part number changed so many times. They also changed the location of this specific factory...this is really odd. Right now, Ford is guaranteeing 300 steering columns being manufactured and released in September and another 300 in October. But there are over 850 people on the pre-order list." So tell me why, this part was recalled like 6+ years ago and all of a sudden now, these same parts are having the same issues. The power steering will just stop working whenever it wants. Every single ford parts guy I talked to at the 3 different Ford's I talked to said all of the above is very suspicious. "It seems like Ford never fixed the problem and it trying to cover their ass".
