Mercury Mountaineer Problems

Throughout the years Mercury Mountaineers have faced various different problems. While most of the problems have been solved throughout the different generations of manufacturing, it is still important to be aware of the different problems you should keep an eye on.

Problems with First Generation Mountaineers

One of the major problems that first generation Mountaineers (those manufactured between the years 1997 to 2001) experienced is the failure of a few different parts. These parts included the intake manifold gasket, front timing chain tensioner, the differential feedback EGR sensor and the mass airflow sensor. The failures of these different parts were covered under a recall for up to 72,000 miles. Additionally, the 1997 and 1998 models were faced with heating and air conditioning problems which were caused with the failing of the blend door and heater case.

Problems with Second Generation Mountaineers

A problem the second generation of Mountaineers (those manufactured between the years 2002 to 2005) faced was a problem with the engine noise. This problem could be resolved by replacing the transfer case drive chain. Additionally, some of the clutches in these models were faulty and the oil was prone to leak from the right side axle.

Problems with Third Generation Mountaineers

The third generations of Mountaineers tend to have problems with overheating brakes, dragging brakes, coolant leakage, and steering noise. Additionally, the transmission of these vehicles may become stuck in park. To fix this grease must be removed from the shift lockout switch.
