Mercury Mountaineer RecallsFord and Mercury Recall 2010 Models for Improper Seat Back Retention Requirements
Ford has recalled certain 2010 model year Ford Explorer, Explorer Sport Trac, Fusion, and Fusion Hybrid vehicles along with Mercury Mountaineer, Milan, and Milan Hybrid vehicles for an issue with the front seat backs equipped with manual recliner mechanisms. In the event of a crash, the seat back and head restraint may move rearward, increasing the risk of injury. This is due to incorrect specification in the design of the gear plate teeth on the seat back recliner. Dealers will replace the manual recliners free of charge.
A bolt securing the transmission oil cooler lines to the transmission may not have been sufficiently torqued during assembly. If the oil cooler lines separate from the transmission and transmission fluid contacts the catalytic converter, a fire could start. Dealers will inspect and tighten the transmission cooler line attachment. The recall began August 30, 2007. The Ford recall number is 07S56.
