2009 Mercury Mariner Electrical Problems

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. 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.

My SUV was part of a recall due to the electronic power steering failing. My SUV was allegedly repaired by the cheapest of the three available options (computer reset or some such process). I bought my SUV in 2020. The electronic power steering slowly started going out intermittently and then more frequently over time, but is now completely out. The dealer tested my SUV and stated that the entire steering column needs to be replaced. They claim that the problem has nothing to do with the recall, but I don't believe them. My issue is the exact same issue that prompted the recall in the first place. I should not have to pay for a failed recall repair. I think it's possible that the original dealership faked the repair, or simply chose the cheapest (but not proper) option to save themselves time and money. My shoulder is now damaged due to driving without power steering for so long. I need an honest evaluation of my vehicle and an investigation into whether or not the original dealer performed the proper repair. I would assume that the issue wouldn't come back if it had been repaired properly the first time.

Electronic Power Steering System, which was part of a previous recall, and was allegedly fixed, but continues to experience the same loss of power steering. This is a continual problem, meaning that it is not a one time incident. Yes, the vehicle is available for inspection at any time. When the power steering goes out while driving, the steering wheel jerks to one side, and feels like a lock-up. The vehicle is still drivable, but can be dangerous in a situation where attempting to avoid an obstacle, could result in an inability to do so, because the maneuvers are being executed for a vehicle with power steering, so when it goes out, those same corrections will not successfully avoid a collision. The dealership is aware of the problem. They did a system check and insist that the steering column needs to be replaced, and that it has nothing to do with the previous recall, but it is exactly the same problem involved with the recall, therefore I do not believe they are differing issues. I believe the initial recall repair was unsuccessful, or the wrong fix. There were three or four options for fixing the issue. There are no warning lights that come on prior to the power steering going out, but a click can be heard however, at the exact moment when the mechanism for the power steering goes out. The same click can be heard when the vehicle is started and the power steering does come on. It usually comes on when it is cold outside. It will then go out once the car gets warm. I bought the car in January of 2000, and I did not experience the issue for a few months. When it did start happening, it was only once in a while - maybe every few months. The problem started happening more frequently with time, with the current status being that the power steering is predominantly not working.

VEHICLE SUDDENLY LOSES POWER STEERING ASSISTANCE WHILE DRIVING. IF THE IGNITION KEY IS CYCLED THE POWER STEERING ASSIST MAY FUNCTION AGAIN. THE AFFECTED COMPONENT WAS DETERMINED TO BE THE POWER STEERING CONTROL MODULE (PSCM) WITHIN THE STEERING COLUMN. A RECALL WAS ISSUED FOR THIS IN 2014, HOWEVER ONLY THE SOFTWARE WAS UPDATED WHEN THE VEHICLE WAS BROUGHT IN FOR REPAIR. THE MALFUNCTIONING COMPONENTS WERE NOT REPLACED AND THE ISSUE HAS RETURNED.

MY MERCURY MARINER 2009 HAS HAD ISSUES FOR THE PAST YEAR IN REGARDS TO THE VEHICLE UNEXPECTEDLY GOES INTO "LIMP HOME MODE" AT REDUCED POWER, LIKE WHILE SITTING AT TRAFFIC LIGHT OR STOP SIGN. ALSO, THE WRENCH LIGHT WILL GO ON WHILE DRIVING AND I LOSE ACCELERATION POWER. I CAN PUSH THE GAS PEDAL DOWN AND NOTHING HAPPENS, THE ENGINE IS STILL ON BUT NO ACCELERATION POWER. I WILL COAST UNTIL I CAN GET TO A SAFE SPOT TO HAVE TO POWER IT OFF AND THEN RESTART IT. THIS IS VERY DANGEROUS WHILE DRIVING IN RUSH HOUR BACK AND FORTH TO WORK EACH DAY. THE CAR LAGS WHEN ACCELERATING AND ALSO PUMPS WHILE WHEN COMING TO A STOP. I DO NOT FEEL SAFE IN THE CAR AND WISH I HAD NEVER BOUGHT IT. I CAN'T EVEN MAKE A TRIP TO THE STORE WITHOUT WORRYING ABOUT THE WRENCH COMING ON OR IT GOING INTO LIMP MODE. *TR
