Reliability, common problems and owner reviews for the Subaru Impreza / Forester 2.0D Boxer diesel (EE20). Check this before you buy used.
The world's first boxer diesel — torquey and economical, but the early EE20 (2008–2011) is known for crankshaft failures (a serious, expensive fault), plus dual-mass-flywheel/clutch wear and DPF clogging on short trips. Later cars improved. A high-risk buy unless it's a later unit with strong history.
