Summary Verdict
The 2009 Mitsubishi Endeavor generally presents a mixed reliability profile. The 3.8L V6 engine, while robust, can experience issues with intake manifold gaskets and requires timely timing belt replacement. The automatic transmission is prone to slipping or hesitation, often requiring fluid services or more extensive repairs. Suspension components like control arm bushings and strut mounts are common wear items that may need attention. Electrical issues, such as failing power window motors and alternators, have also been reported. Exterior and interior components, like rear hatch struts and HVAC resistors, can also present minor annoyances. Overall, while not plagued by widespread critical failures, owners should be aware of these potential repair areas and maintain a proactive maintenance schedule.
