Summary Verdict
The 2007 Mitsubishi Endeavor presents a mixed reliability profile. While its exterior and general cabin components are relatively robust, owners should be aware of potential issues with the powertrain, particularly the transmission, which can experience slipping or hesitation. Engine concerns like intake manifold gasket leaks and timing belt issues are also noted, with the latter being a critical failure point if not addressed proactively. Suspension components, such as control arm bushings and strut mounts, can wear over time, leading to noise and handling degradation. Electrical issues like failing power window motors and alternators are also within the realm of common repairs for this model year. Regular maintenance, especially for the transmission and timing belt, is crucial for maximizing the longevity and reliability of the Endeavor.
