A quick google search of this common issue will tell you : Ford owners forum groups with the same issue, complain that Ford apparently only did reprogramming and did not replace the actual part causing the issue, when checking the codes, it did not show the failure yet, so they reprogrammed the unit to check the box Ford completed the safety recall. Recall 14v284000: loss of power steering assist NHTSA campaign id number: 14v284000 "steering:electric power assist system" (5/28/2014) summary: 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. Consequence: 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. Https://auto-recalls. Justia.

6 Steering problem

Failure Date: 11/01/2024

This is an update to the complaint from June- because I have to compensate manually for the electric power steering, I’ve aggravated upper back injuries and strained hip muscles I incurred from work. I have to attend physical therapy for those injuries now, but it’s useless if my only mode of transportation prolongs my recovery. —— my 2009 Mercury Mariner’s steering wheel started locking up 3 months ago, and it’s hard to get the steering wheel and the tires to agree on one direction. I looked up the make and model to see if there was a safety recall for it and there was, but my VIN wasn’t included in the recall campaign, even though it fits the criteria exactly. ///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.

11 Steering problem

Failure Date: 03/01/2024

Months back there were times the power steering would go out, it would be for short amount of times and always came back. As of 40+ days ago the power steering has totally gone out and has not once come back. The dash says "power steering assist fault" the other issue is the wrench on the dash. It's normally after driving for quite some time. Even if there has been a break on the car while grocery shopping etc. When it comes on the car goes into limp mode. Very dangerous as we cannot tell when it'll happen. There has been multiple times the light turns green we take off, get to about 15-20mph and she just stops. The dash reads to safetly pull over and I believe it says to shut off the car. This has been happening for 5+ months. There is also random over heating when that happens. This is based on how I remember it. Because of the safety issues I have not driven the vehicle. My husband drives it because he can handle no power steering better then me. . . Not that it's better for anyone to use. .

16 Steering problem

Failure Date: 06/08/2023

About 3 months ago, my power steering started to fail. After researching to find out the problem, we learned that my car does not have a power steering pump, as it is electronic. I learned that my car had a recall from Ford pertaining to the power steering failing. I called Ford and they told me that my car was part of the recall and was "fixed" in 2015. A month ago I took it to a Ford dealership to have them do a diagnostic on my car and they informed me that it was my power steering torque sensor, which I already knew this by researching the issue. The issue now lies in the fact that the part is on back order and there is no available date. I believe that Ford should have replaced the parts needed instead of doing a "bandaid fix" by doing a software update, which they knew would not be the fix to the problem. Ford got away with not fixing something that is very dangerous to those who drive the Mercury Mariners. Mine is an 2009 and it is now dangerous on the highways to drive. I would like to add that while driving my car now with this issue, my battery light comes on, which is also a known issue to Ford.

18 Steering problem

Failure Date: 03/04/2023

Driving and my steering totally quit. . . Almost wrecked it was so hard to control. Had not had any previous issues prior to this. I had my vehicle towed to mechanic and code that came up says steering assist has failed and will need to replace whole steering column assembly. There was no warning light. . . Nothing! upon my research, I see this is a frequent problem and there was a recall (1 million vehicles) but only for certain models, and of course mine is not one, in fact I haven't read any reports where the steering column was replaced, only reprogrammed and then the problem comes back. My car was manufactured at the kansas city plant, which I have seen complaints numerous times for this problem coming out of this facility. Mechanic contacted Ford to inquire about the part. . . Was told it was a 6 month minimum time to get the parts!! 6 months. . . Am I just sol for 6 months since my car cannot be driven safely? I purchased a Ford because they were not part of the government buyout. . . Big mistake. At this point, I cant have it repaired with no parts. They know this is an ongoing problem, yet refuse to do anything about it.

19 Steering problem

Failure Date: 02/06/2023

I have been intermittently losing power steering. The code is b1342. After researching, it looks like Ford is aware of this problem but is unwilling to fix the issue. This fix must be done at a dealership since it is a software issue and going to cost $2,000. Obviously losing power steering when going at fast speeds is incredibly dangerous for myself and others. There is no check engine light that comes on when the issue arises.
