2005 Mercury Monterey recalls

3 NHTSA recall campaigns list this model year.

  1. NHTSA 13V081000Mar 7, 2013Structure & Body196,667 vehicles

    Seats

    Ford is recalling certain model year 2004-2007 Freestar and Mercury Monterey vehicles manufactured from March 24, 2003, through November 7, 2006, equipped with a third row seat and originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. The third row stowable seat can experience corrosion and structural degradation at the seat anchor mechanism mounted to the rear wheel wells. As a result of the corrosion, the third row seat may not fully latch into its seating position.

    Risk: In the event that the vehicle is crashed into from the rear, an unlatched seat may increase the risk of personal injury.

    Remedy: Ford will notify owners, and dealers will install new third row seat latch striker mounting brackets, free of charge. The recall began on March 28, 2013. Owners may contact Ford Motor Company Customer Relationship Center at 1-866-436-7332.

  2. NHTSA 12V006000Jan 9, 2012Transmission & Powertrain206,452 vehicles

    Power train:automatic transmission:torque converter

    Ford is recalling certain model year 2004 and 2005 ford freestar and mercury monterey vehicles. The torque converter output shaft may fail.

    Risk: This condition results in a sudden loss of motive power with no warning, increasing the risk of a crash.

    Remedy: Ford will notify owners, and dealers will replace the torque converter free of charge. The safety recall began on august 9, 2012. Owners may contact the ford motor company customer relationship center at 1-866-436-7332.

    On certain vans equipped with the power liftgate option, the power liftgate motor automatically disengages after the liftgate is powered open.

    Risk: In the event of a liftgate strut malfunction, the liftgate can fall freely with no prior warning. Anyone standing beneath the liftgate may be injured if the liftgate falls.

    Remedy: Dealers will reprogram the power liftgate module to reduce the likelihood that the liftgate could fall free of charge. The recall began on march 15, 2006. Owners may contact ford at 1-800-392-3673.
