1% of complaints about the 2009 Mercury Mariner came in the first year, which is unremarkable for a 2009 vehicle — around the middle of the 212 model-years on record. The median complaint arrives at 7.4 yr in service. The most-reported system is steering (166 complaints), typically at 9.9 yr or about 119,588 miles.
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.
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.
