Best Model Years
Later first-generation models (2008-2009) saw some refinements and generally had fewer widespread reports of the most severe issues.
Years to Avoid

Top Risk Areas
The systems that tend to fail first on the 2005 Chevrolet Equinox, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The Aisin AF33 5-speed automatic transmission is prone to solenoid failures, leading to harsh shifts, delayed engagement, and eventual complete failure. Torque converter issues are also common.
The 3.4L LA1 V6 engine frequently develops leaks at the lower intake manifold gaskets. This can lead to coolant loss, external leaks, or internal mixing of coolant and oil, which can cause severe engine damage.
Owners report issues with the Body Control Module (BCM) causing various erratic electrical behaviors. Power window regulators/motors, door lock actuators, and HVAC blend door actuators are also common failure points.

At this point, the lower intake manifold gasket is a prime suspect for leaks, and transmission issues (solenoids, hard shifts) become increasingly likely. Suspension components will likely need attention. Budget for repairs.
High Risk Zone
Beyond 120,000 miles, the risk of major component failure, particularly the transmission, significantly increases. Extensive suspension and steering overhauls are probable. Thorough pre-purchase inspection or a substantial repair budget…
