Summary Verdict

The 2010 Pontiac Matiz is a basic city car with a reliability profile that aligns with its budget-friendly nature. Common issues tend to be concentrated in areas like oil and coolant leaks from the engine, clutch wear on manual transmissions, and potential actuator problems with the automated manual. Suspension components, particularly bushings and ball joints, can wear out, leading to noises and handling issues. Electrical gremlins, such as alternator failures, and exterior rust are also points to consider. While not plagued by widespread catastrophic failures, owners should be aware of these potential maintenance and repair needs to keep the vehicle in good working order.
