Problems:

Oil consumption
The LE5 engine in the 2006 Chevrolet Cobalt is known for higher than average oil consumption, which can lead to low oil levels and potential engine damage if not monitored regularly.
Timing chain wear
The timing chain and associated components in the LE5 engine can wear prematurely, resulting in noise and potential engine timing issues.
Fuel pump failure
The fuel pump in this model can be prone to failure, leading to stalling, rough idling, and difficulty starting the engine.
Coolant leaks
The engine may develop coolant leaks, particularly around the water pump and thermostat housing, which can lead to overheating if not addressed.
Ignition coil and spark plug issues
Misfires and rough running can be caused by faulty ignition coils and worn spark plugs, which are relatively common in this engine.
Intake manifold gasket failure
The intake manifold gasket can deteriorate over time, causing vacuum leaks, rough idling, and poor engine performance.
Throttle body problems
The electronic throttle body can malfunction, leading to issues with acceleration, idle, and overall engine response.
