4 known faults
On the 2.0D diesel, the particulate filter is cited as a weak point, especially in urban use and on short journeys that prevent regeneration (Kit Ethanol Auto, Carverif). Part of the diagnosis comes from specialist sites rather than manufacturer statistics.
Recalls in Hong Kong (Forester 2013-2016) and Japan (Forester 2013-2015) concern corrosion of the rear coil spring, which can lead to its breakage. No European recall has been found: have it checked at a dealership with the serial number.
Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

User reports cite gearbox leaks, slow gear changes or jerking at low speed, sometimes improved by a software update at a dealership (Canberra Times, Au7o).

FB20/FB25 family boxer petrol engines are known for oil consumption that varies greatly from one example to another, attributed to the piston rings; some engines have been replaced in other markets (Cherish Your Car, Au7o). Check the oil level and the oil change history.

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
