Summary Verdict

The 2007 Pontiac Matiz, while economical to purchase and operate, presents several potential reliability concerns typical of its age and segment. Engine issues like oil leaks and cooling system problems are common, especially with the smaller 0.8L engine. The 1.0L engine can be susceptible to timing belt failure if not maintained. Transmission issues, particularly with the automatic, can lead to costly repairs. Suspension components like ball joints and tie rods are prone to wear, and electrical issues such as alternator failure are not uncommon. Exterior rust can be a significant concern depending on climate. Interior wear is also expected. Regular maintenance, especially for the timing belt and cooling system, is crucial for mitigating major issues.
