Mercury Mountaineer Problems

Vacuum leak from intake manifold O-ring gaskets

The intake manifold O-ring gaskets commonly leak, causing stalling and poor idle quality; the Check Engine Light will illuminate.

Worn Timing Chain Cassettes May Cause Rattling Noise From Engine

A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.

Rough idle when cold due to upper intake manifold gasket leak

The Check Engine Light will illuminate and the engine will idle roughly when cold. There are updated upper intake manifold gaskets to resolve the problem.

Mercury Mountaineer Recalls

Ford 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.
