2004 Subaru Forester ProblemsCheck Engine Light Due to Failed Catalytic Converter
The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.
An oil leak can develop from the spark plug tube seals. Excess oil in the spark plug tubes can result in engine misfires and illumination of the Check Engine Light. Our technicians tell us that removing the valve cover and replacing the tube seals and cover gasket is necessary to correct this concern. Oil damaged spark plugs, ignition wires, and ignition coils will also require replacement.

2004 Subaru Forester RecallsFront Lower Control Arms May Break
The front lower control arms may break at the hanger brackets due to corrosion. This corrosion is commonly a result of the hanger bracket being exposed to salty conditions, such as roads where salt is used as a snow melting agent. A broken control arm can result in loss of vehicle control, increasing the risk of a crash. Dealers will inspect the affected control arms and rustproof or replace them as necessary. The Subaru recall number is WVX-34.
On 26 vehicles, the engine oil control valve cover may not have been tightened properly, which could allow oil to leak. If leaking oil contacts hot engine components, a fire could result in the engine compartment. Dealers will inspect and retighten the oil-flow control valve cover bolts. The recall began October 8, 2004. The Subaru recall number is WWU-05.
