2004 Subaru Forester Problems

Engine Misfire Due to Failed Spark Plug Wires

Sometimes the Check Engine Light illuminates because the computer detects misfires. Subaru released an improved spark plug wire set to solve the problem. The ignition coil should also be inspected for carbon tracks or short circuits between the contacts

Check Engine Light Due to Failed Catalytic Converter

The Check Engine Light may illuminate because of low catalytic converter efficiency. This same issue may cause the car to fail the State Smog Test if one is required.

Check Engine Light Due to Failed Front O2 Sensor

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.

2004 Subaru Forester Recalls

Front 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.

Engine Oil Leak From Oil Control Valve Cover

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.

At 5 years old and 30k miles no problems yet. Gets door dings easily, and some bits in the interior have been easily damaged, but overall been extremely reliable.
