Summary Verdict
The 2000 Pontiac Grand Am, while offering a sporty aesthetic, exhibits common issues for its age and platform. The 2.4L and 3.4L engines are prone to intake manifold gasket leaks, with the V6 also susceptible to head gasket failures. Automatic transmissions (4T40-E) can develop shifting problems and torque converter issues. Suspension components like struts and ball joints are typical wear items. Electrical gremlins, particularly related to the BCM and alternator, can also arise. Exterior rust and interior wear, such as cracked dashboards and HVAC blend door failures, are also frequently reported. Regular maintenance and prompt attention to these known issues are crucial for maintaining the Grand Am’s reliability.
