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
The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.
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.
