Summary Verdict
The 2000 Mercury Mountaineer is a generally dependable SUV, but potential buyers and current owners should be aware of common issues. The 4.0L V6 engine can experience camshaft synchronizer and intake manifold gasket problems, while the 5.0L V8 is typically more robust. Transmission issues, particularly with the 5-speed automatic, such as torque converter and solenoid pack failures, are notable. Suspension components like ball joints and control arm bushings are also areas that may require attention over time. Electrical gremlins, including window regulators and instrument clusters, and interior issues like HVAC blower motors are also reported. Despite these points, with proper maintenance and addressing these specific potential failures, the Mountaineer can remain a functional and comfortable vehicle.
