Mercury Mountaineer ProblemsHeater Stuck on Hottest Setting Due to Broken Heater Blend Door
A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.
A coolant leak may develop from the radiator. Ford has released and updated radiator and powertrain control module (PCM) software update to address this issue. The software update includes revised cooling fan operating parameters. Failure to complete both service procedures may result in repeated radiator failures.
4wd vehicles may develop a squealing noise coming from the front wheels when driving below 30 mph. This is generally caused by dry excluder seals, lubricating the seals will commonly correct this concern.

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.
