2008 Subaru Forester Problems
The Check Engine Light may illuminate because of a failed knock sensor. Although the sensor often tests okay, it can fail intermittently, while the vehicle is being driven.
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
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.
There is a technical service bulletin on the ABS control module. It is replaceable without having to replace the entire anti-lock brake hydraulic unit. Previously, the ABS control module was only available as a complete assembly that included the hydraulic unit.

RepairPal Expert Overview:
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.
