Summary Verdict

The 2006 Chevrolet Malibu is a generally competent sedan, but potential buyers should be aware of common issues. Engine oil and coolant leaks from intake manifold and valve cover gaskets are prevalent for both engine options. Automatic transmission problems, such as slipping and torque converter issues, can be costly to repair. Suspension components like struts and ball joints may require attention. Electrical gremlins, particularly related to the BCM and alternator, can also arise. Exterior rust, especially in harsh climates, and interior issues like failing blend door actuators and power window regulators are also noted. While not overwhelmingly problematic, these areas represent the most frequent technical concerns beyond standard wear and tear.
