Summary Verdict

The 2006 Chevrolet Equinox, particularly with its V6 engine options, can be a reliable vehicle if common issues are addressed proactively. The most frequently reported problems tend to be related to the engine’s intake manifold gaskets and potential oil leaks on the 3.4L V6, and timing chain concerns on the 3.6L V6. Transmission issues, such as slipping or torque converter problems with the 5-speed automatic, are also noted. Suspension components like struts and control arm bushings may require attention over time. Electrical gremlins, including window regulators and instrument clusters, and interior items like HVAC blower motors and door lock actuators, are also areas to monitor. While not overwhelmingly problematic, these specific components represent the most common areas for potential repair on this model year.
