Does the 2005 Mercury Mariner have recalls?

3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.

15V606000TransmissionSeptember 29, 2015 · 57 units

Defect

Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.

Consequence

If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.

Remedy

Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.

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.

Consequence

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.
