The power steering assist is malfunctioning and it is available for inspection upon request. The steering wheel is very difficult to turn, it's as if the power steering assist is keeping the wheel from turning. No, but I spoke to someone at Ford and they said that it sounded like my car should be in the recall that was announced for my vehicle type but my VIN was not included in the recall. My car has not been inspected by anyone but it says right on the dash board digital display that there is a "Power Steering Assist Fault". Ford does this with many vehicles they recall, a lot of vehicles that should be included in the recalls are not and we're supposed to foot the bill for their lack of concern for public safety? It's going to cause an accident but it's my only working car and I can't afford to pay for their mistakes. How many have died due to their negligence I'm wondering.
I recently purchase 2010 Mercury Mariner. There is a few errors appearing on the screen in front of the steering wheel. One of the error is "CHECK FUEL LINES." It also has an error about the tire pressure sensor. It also rides roughly, but the wheels are like new, so it feels like the suspension or shocks have something wrong with them. Also, there is a lot of play in the steering wheel when driving it. When I went to check on the recalls in the system by putting in my VIN, it shows that there are no recalls on my vehicle. However, these errors and issues are connected to the recalls for my vehicle. I am sure that these recalls have not been taken care of for this vehicle and they need to be fixed.

The contact owns a 2010 Mercury Mariner. The contact stated that upon entering a parking lot at a low rate of speed, the power steering assist failed as the power steering assist fault warning message illuminated on the instrument panel. The contact stated that excessive force was needed to steer the vehicle. Due to the failure, the contact had the vehicle towed to an independent mechanic who later informed her that her vehicle was included in NHTSA Campaign Number: 14V284000 (Steering).

"Power Steering Assist Fault" message appeared, and the steering became stiff, indicating the power steering stopped working. This happened while coming down from a snowy mountain pass, which put myself, my passengers, and other vehicles at risk. Even though there was a 2014 recall for this problem, I was told by Ford dealership that there were no open recalls on my car (indicating it was either fixed and broke again, or my car was never included in the recall-- as I purchased the vehicle secondhand, I am unsure which it is). It will be a $1200 fix fat this Ford dealership for a known and dangerous problem that should, but won't, be covered by the previous recall. There should be an easier way to track fixed recalls through the NHTSA Vin lookup program.
