Power steering goes out at regular intervals. In the same type of issue as the following recall notice 14s05/NHTSA or the electric assist system as bad.
The car was driving down the road (a city street, not a highway) and a triangular light came on the dash, along with a message to stop safely. The engine shut down and I had to coast into a parking lot. This had happened previously and I had paid a dealership to replace the hybrid cooling pump. I later found out that this part had been recalled and was reimbursed by the manufacturer for the original repair. The same part has failed again according to the dealership, but upon contacting the manufacturer, they refuse to replace the part again.
I was driving on the interstate in traffic and had a complete loss of power steering, making it nearly impossible to pull over or get off the highway.
The vehicle will stall when it comes to a stop, mid turn, slowing down, and sometimes accelerating. Several websites show 100's of complaints from people with the same issue. It is a may safety concern because it dies at any point while driving.
Speedometer instrument cluster gauges keep going out and causing SUV to not start.
In March 2018, I noticed the steering wheel would shake when coming to a stop sign or stop light and make a grinding sound. It continued to do this every time for a couple weeks. Then toward mid March, I was backing out of a driveway and the power steering totally went out. It stated on panel "power steering default assist. " it took extreme effort to steer the wheel to the side as the steering wheel was extremely rigid. Because it is a safety hazard to drive, it has only been driven to move car in apartment parking lot. I got this vehicle in June 2017 from a car dealer with no warranty. Ford says this VIN # is not included in recall for torque problem with power steering failure. As this is a manufacturing defect and a safety hazard, I want this vehicle VIN added to recall list. If I drive it on open road, it will surely cause injury to my family. I can't even maneuver the steering wheel.
My vehicle was covered under recall 14s05 and said recall work was done in 2014 in va under the previous owner, Ford does not have record of what "step" or part of the recall was done, there are 3 parts. Less than 4 years, the recalled part, the torque sensor in the power steering assist has faulted, which leads me to believe that it wasn't replaced under the recall. Since it's been more than 12 months or 12,000 miles they are not willing to replace the said recalled part that was originally covered. The car was in drive when the assist faulted causing steering to be very difficult and had I been driving at a higher rate of speed could have potentially been accident causing. I feel that the recall work should be extended to replacing the part since it wasn't done originally under the recall or was again replaced with a faulty sensor to fault again within less than 4 years.
Power steering completely failed while operating the car, posing a danger. Transmission lurches on upshift between 1 - 2 gear while accelerating. Electrical system will not charge battery and completely fails while the vehicle is in operation on the highway, posing a danger. Vehicle may or may not restart immediately.
While driving the car on a highway, the warning light chimes and displays to "safely stop vehicle". The car no longer accelerates and slows to a stop even if you don't have a shoulder to pull off to. I normally just hit my hazard lights and pull to a stop, wait a few minutes then restart the engine. This happen once a month and sometimes twice or three times in a row. If the hybrid electronics system overheats, it may shut down the powertrain, resulting in a stall-like condition, increasing the risk of a crash. There is currently a recall on this problem #14s19. Called Ford and they said my vehicle isn't a part of it even though it clearly was built in the same time and has the exact issue. Very dangerous and scary problem.
Steering wheel will freeze up while driving. Steel on steel horrible noise when driving. Shifter gets stuck have to put it in neutral to start it.
Key ignition doesn't work. Car won't start without jiggling key.
Tl- the contact owns a 2008 Mercury Mariner. The contact stated that the vehicle had experienced a problem with shifting the vehicle 2nd and 4th gear. The transmission warning indicator illuminated. The vehicle was taken to the dealer where it was diagnosed that the servo routing cover servo ring was defective and needed to be replaced. The vehicle was not repaired. Prior to this failure the vehicle had it's steering column replaced. The manufacturer was notified of the failure. The vehicle failure mileage was approximately 122,834. Kh.
My parents purchased a 2008 Mercury Mariner this last spring, and just started to notice that the electric power steering is cutting in and out. We took it to our local garage who diagnosed the problem (error code that came up was b1342-2f) and recommended we replace the steering column. Since that is a large expense ($800) I decided to do some research and called the local Ford dealer. They looked up our VIN and told me that there was a recall on the electric power steering and that the work for the recall on the power steering was already done. (Ford's recall number for this is 14s05) my question is since we are experiencing the same failure (meaning the fix didn't seem to last) is there any recourse for us to have Ford fix the problem now? also, how long are these 'fixes' supposed to last? the date the recall was published by NHTSA is 2014-06-05, and we are only in September of 2015. I was thinking that a recall fix should last longer than a little over a year. Is NHTSA in the process of reviewing this issue?.
While pulling away from a stop light ,an attempt to make a right turn was made. In the middle of the turn, the power steering assist quit. The turn was near impossible to complete and I almost ran over a gas station sign. After wrestling the car to a stop in a gas station I turned off the ignition and called my husband. He suggested I have the car towed to a repair shop. While on the phone I restarted the truck and the power assist resumed working. I returned home without incident. Someone is going to be killed if they are not strong enough to control a truck like this without power assist. The power assist has quit three times since and only my husband drives the vehicle now.
Over the last couple weeks we have experienced a loss of power steering and an increasingly severe "shaking" of our steering wheel when it is working. We took the car to the mechanic and was told that we need to replace the entire steering column due to a failure of the electronic power steering. The part alone is $900, $1,400 with labor. .

December, 2013, I was exiting parking lot onto a main street that had 2 lanes of oncoming traffic. Halfway into the street, lost power steering but was able to drift to side of road. January, 2014 car would not go over 25 miles per hour, lost power steering. Fortunately I was near the garage that does my repairs, oil changes, etc. . March, 2014, steering wheel locked, no power steering, had to wait about a half hour until power steering returned. . . Kept turning car off and on every 10 minutes. Contacted Ford customer service 3 times by email (Jan-Mar). My last 3 cars have been Ford products but apparently brand loyalty is not valued. Replies were--sorry you are having issues-no follow up from Ford even when hey knew they were issuing a power steering recall as of April-may, 2014. I paid $2,500 in repairs from Dec'13-Mar'14.
Vehicle shut down while driving on the interstate at approx. 65 mph, immediately losing all power. Message on dash read "stop safely now". This is a very dangerous issue. Driving on the interstate at 65 mph and it has occured 8 times since I purchased this car. Ford has repaired the car for this 3 times (in 2009, 2010, 2013), the first 2 it was under warranty, this last one the repair cost was $350. What is terrifying about this situation is that it occurs without warning and you have about 10 seconds to react, I've been very close to getting rear ended a couple of times. I was able to restart the vehicle every time, but what surprises me is that even though this situation is so serious, I did not find out until now it's so common. I will be shopping for a new car soon, I had enough. I kept the car this long because other than this issue, I really love driving it.
