2009 Mercury Mariner Owner Complaints

My vehicle was returned to me following a torque sensor replacement on 4/9/2026 in poor condition (locked steering and a catastrophic gash in the driver-side tire) rendering it undrivable and unsafe. Crossroads Ford of Prince George shop's inspection report claims the tire damage was pre-existing, I have conclusive evidence to the contrary: Virginia State Inspection: My vehicle passed a Virginia state safety inspection on 2/27/2026. Per state law, any tire with a gash or sidewall crack is an automatic failure. This legally certifies the tire was intact immediately prior to their service. Recent Tire Service: I replaced my rear tires at OK Tire and Auto on 3/30/2026. At that time, a full tread and sidewall inspection of my front tires confirmed they were in good condition. The timing of the dealership's communication confirms the damage occurred while in their care: I arrived for my 9:30a appointment around 9:25a. No damage was noted during the initial intake. I was in their facility when I watched a mechanic drive to the other side of the service parking lot without being informed of a "catastrophic" safety issue. I was only notified of the gash at the end of the day when the vehicle was scheduled for return. Their staff now deems the vehicle "unsafe to drive" for their own employees. If this gash were present at 9:30am, it would have been told to me before I left the dealership. The locked steering is a direct result of an improper torque sensor installation (which is the reason why I was dropping my car off to be serviced). My car was in driving condition as I drove it to the dealership for my appointment with no issues. I received a call from advisor Sade Gregory at 11:03 informing me that I would need a steering column now that is on backorder. At 11:13am I received a confirmation for car delivery to me then at 1:06pm confirmation that my car will arrive at my house at 1:15. At 1:20 Sade Gregory says my car can't be delivered now because its unsafe for them.

Drivers rear shock rusted off the wheel well causing wheel to snap and metal frame to hit the ground while I was traveling 40 mph. At this time the other wheels locked up and started squealing causing loss of control of vehicle shooting me across lanes and hitting curbs on both sides. This was heard all the way inside a church and they came running out. If I had not been able to gain control it would have flipped. The vehicle is available for inspection. It has not been reproduced or confirmed by a dealer or independent service other than the tow truck attendant telling me that the car need to be junk because it could not be repaired. The component has not been inspected by the manufacturer, or insurance company as it only has liability insurance. A police officer did show up on seen to direct traffic around vehicle and did see the issue but no report was taken. There was absolutely no indication that this was an issue until a few seconds before it snapped and that was the wheel started to wobble.

Power steering stopped working completely.... was taking a turn and the steering became stiff and shook a little and went back to normal. Parked the car. started the car 2 hours later and steering completely stiff... no power steering. 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.

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.

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..

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.
