What owners say
The contact owns a 2010 Mercury Mariner. The contact stated that after starting the vehicle, the message "Power Steering Assist Failure" was displayed, and the steering wheel became extremely difficult to turn in either direction. The local dealer and manufacturer were notified of the failure, but no assistance was provided. The contact was informed that the vehicle was previously repaired under the federal safety agency Campaign Number: 14V284000 (Steering), which the contact related to the failure. The cause of the failure was not yet determined. The failure mileage was 185,000.
Power Steering assist fault went out with no warning. Now steering wheel is locking up while driving. Also when trying to gain speed the vehicle bogs out.
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.

My vehicle has been running out of gas extremely quick. It also leaks underneath when I am pumping gas into the Mariner. I am having a loud thunking sound underneath the vehicle an when I let off the accelerator, my car slowly comes to a hault. My power steering went out one day also without warning. I can't figure the problem out except I seen a recall for the power steering module or some sort that has malfunctioned an causes the computer to erase the power steering sensor completely clean of it's existence. Please help!

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 the federal safety agency Campaign Number: 14V284000 (Steering). The contact called the dealer and the manufacturer who informed her that there were no recalls on her vehicle. The vehicle was not repaired. The failure was unknown.
"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 federal safety agency Vin lookup program.

Steering: electric power assist system
- What is wrong
- Ford Motor Company (Ford) is recalling certain model year 2008-2011 Ford Escape and Mercury Mariner vehicles manufactured August 18, 2006, through September 11, 2010. The affected vehicles have a steering torque sensor that may not be able to properly detect driver steering input. As a result, the system could remove the Electric Power Steering (EPS) assist.
- Risk
- If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
- Remedy
- Ford will notify owners, and dealers will update the software for the power steering control module (PSCM) and the instrument cluster module, free of charge. If a vehicle shows a history of a loss of the torque sensor signal or fault codes relating to the PSCM when the vehicle is brought in for the recall remedy, the affected components will be replaced, free of charge. The recall began on July 18, 2014. Owners may contact Ford customer service at 1‑800‑392‑3673. Ford's number for this recall is 14S05.
