Summary Verdict

The 2006 Mercury Monterey is a capable minivan with a generally solid mechanical foundation. The most common reported issues tend to be related to the engine’s intake manifold gaskets and timing chain wear, as well as potential transmission problems like torque converter shudder or slipping gears. Suspension components such as ball joints and tie rod ends can wear over time, leading to steering and noise issues. Electrical gremlins, particularly with power windows and instrument clusters, are also noted. Exterior and interior components, like the rear hatch latch and HVAC blower motor, can also require attention. While not immune to problems, addressing these potential issues proactively can help maintain the Monterey’s overall reliability and comfort.
