Safety recalls — NHTSA campaigns

16V777000 2016-10-26
Fuel system, gasoline:delivery:fuel pump

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.

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

15E045000 2015-06-03
Suspension:front:wheel bearing

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.

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

14V284000 2014-05-29
Steering:electric power assist system

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.

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.
