One problem related to engine head gasket failure has been reported for the 2012 Subaru Forester. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Subaru Forester based on all problems reported for the 2012 Forester.
Engine using synthetic ow-20 oil per dealer recommendation uses oil faster than new car should. Oil changed 18,951mi. At around 22,000 oil was noted leaking around oil filter. Also dipstick showing low level. Owner had to add oil while on a trip. After 24,393mi oil filter leak reported, dealer replaced gasket 803916010 and topped off oil. At 26,312 mi, oil again changed by dealer. 3k mi later (29,000mi) oil again showed below low on dipstick requiring owner to add oil. 32,191 mi service appointment oil change by dealer states "close to full. " dealer told us that cars use a quart of oil every thousand miles normally. No leak found on inspection. I always park in the same place at parking garage and there are no oil leaks on the concrete. My family has had 2 other new Subaru vehicles since 2003 which also use synthetic oil and no other car has had this oil usage. I have owned 6 new cars in my lifetime. I know how to maintain an engine by frequent checks and maintenance. My concern is that owners may lose an engine due to seizure if they follow Subaru recommended oil change by mileage or months. Some owners who are not diligent in checking frequently may lose an engine. My other concern is that either Subaru engine design, gaskets, or other parts may be to blame in excessive oil usage. Please investigate this problem.
