Common Wear Items:
As with many vehicles of this era, common issues can include suspension component wear (bushings, ball joints), minor electrical gremlins, exhaust system corrosion, and potential for head gasket issues on higher mileage engines if maintenance is neglected.
Engine Specific Concerns:
The Ecotec engines, while generally reliable, can sometimes experience issues with intake manifold gaskets or minor oil leaks if not properly maintained. The manual will detail diagnostic procedures for these.
