The official notice
Defect
On certain vehicles, the positive crankcase ventilation (PCV) valve could fail. If you continue to operate the vehicle after this happens, pieces of the PCV valve may enter the engine and cause an engine failure.
Safety Risk
A sudden loss of engine power could increase the risk of a crash.
Remedy
Subaru will notify owners by mail and instruct you to take your vehicle to a dealer to replace the PCV valve. Additionally, the replaced PCV valve will be inspected. If the valve is found to have separated, the separator cover and oil pan will be removed. If the separated parts are not located, the engine short block assembly will be replaced.
