Forester — Generation guide
SH (2009–2013)
Bigger, more SUV-like. 2011+ got the new FB25 (much improved over EJ25 head-gasket-wise). Naturally-aspirated only after the XT was killed in 2013.
Documented problems (2009–2013)
All problems →FB25 Excessive Oil Consumption
2011-2015 Foresters burn 1 quart per 1,000 miles — class-action settlement covers ring replacement.
Repair: $0–$3,500
Rear Differential Whine
Owners of 2010-2018 Subaru Foresters may experience a noticeable whining noise coming from the rear of the vehicle, often indicating an issue with the rear differential.
Repair: $1,200–$2,500
Forester XT Turbo Failure — Banjo Bolt Filter Clog to Full Turbo Destruction (2004-2013)
The clogged turbo-oil-feed banjo bolt filter starves the turbocharger of oil. Caught early it's a $120 bolt service; ignored, it takes out the turbo and often the engine.
Repair: $120–$6,000
