Fuel System, Gasoline › Delivery › Fuel Pump16V777000
Filed Oct 26, 2016329,265 vehiclesFord Motor Company

Defect. Ford Motor Company (Ford) is recalling certain model year 2010-2012 Ford Escape vehicles manufactured February 26, 2009, to April 29, 2012, and 2010-2011 Mercury Mariner vehicles manufactured February 25, 2009, to December 12, 2010. On vehicles with a 3.0L engine, the Fuel Delivery Module (FDM) may crack, causing a fuel leak.

Risk. A fuel leak in the presence of an ignition source increases the risk of a fire.

Remedy. Ford will notify owners, and dealers will replace the FDM flange with one that has a redesigned fuel supply port, free of charge. Remedy parts are currently unavailable. Interim notices were mailed to owners on December 13, 2016. Owners will receive a second notice when remedy parts become available. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S41.

Suspension › Front › Wheel Bearing15E045000
Filed Jun 3, 2015576 vehiclesTimken Company

Defect. The Timken Company (Timken) is recalling certain aftermarket front wheel bearings, part number 510072, sold from January 22, 2015, to May 21, 2015, to be used as service parts on 2001-2012 Ford Escape, 2001-2011 Mazda Tribute, and 2005-2011 Mercury Mariner vehicles. The affected wheel bearings have incorrect dimensions of a 42mm bore, 76mm outer dimension, and 39mm width, instead of a 42mm bore, 78mm outer dimension and a 45mm width.

Risk. Use of an incorrectly sized wheel bearing can adversely affect the braking and steering of the vehicle, increasing the risk of a crash.

Remedy. Timken has begun notifying distributors who will offer purchasers replacement wheel bearings, free of charge. The recall began on May 21, 2015. Owners may contact Timken customer service at 1-866-984-6536.

Steering › Electric Power Assist System14V284000
Filed May 29, 2014740,878 vehiclesFord Motor Company

Defect. 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.

While my wife was driving the vehicle, the power assisted steering failed and produced a "power assist fault code" on the display. The car became too hard for a 74 year old woman to be able to steer. I took the car to the Ford dealer near me who confirmed it was the steering torque sensor had failed and needed to order in one and would cost $600 to replace. I did a VIN search on your data base, but it didn't show any recalls for this problem. However a google search showed a recall for my vehicle make, model and date of manufacturer and part of the Ford 14SO5 recall. The information on your web site shows that Mercury Mariners manufactured prior to Sept.11, 2010 were affected. Mine was manufactured in August of 2010. According to the Ford notices as published on your web site my car should be part of that recall and should receive a software update that would prevent the steering assist from being turned off. The Ford dealer is refusing to do the update and sensor replacement for free since that recall doesn't show up under my VIN. Its funny, because my car is doing the exact thing the recall was for and fits the vehicle description and date of manufacture to qualify.

This car has excessive under body rust under all the wheels wells. I was just told that my car would not pass a State Inspection because the on the front drivers side there is a bracket that holds up the engine is almost totally gone. I have read and over that this vehicle has a known rust and corrosion issue and Mercury/Ford has not been made responsible. I bought this car from a Ford Dealer in Aberdeen, MD used in 2018 and made them aware that I noticed rust on the rear wheel panels. They told me there is no recall however now I am not in a position to purchase or fix the entire under carriage of this vehicle. And I do not feel safe that an important bracket supporting the engine is totally rusted out.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
