Known Issues
|
Engine Oil Consumption:
|
Some Ecotec engines, particularly early 2.2L models, can exhibit higher oil consumption. Proper monitoring is advised.
|
Suspension Components:
|
Wear on front struts, sway bar links, and bushings can occur, leading to noise or handling issues.
|
Power Steering Pump:
|
Leaks or failure of the power steering pump can occur, affecting steering assist.
|
Catalytic Converter:
|
Some models may experience premature failure of the catalytic converter, often indicated by reduced engine power or check engine light.
