Is the Subaru Forester Reliable? Engine History by Year
By Caropsy · June 30, 2026 · 5 min read
The Subaru Forester is searched almost as often as the Outback for the exact same reason — Subaru's reputation is excellent overall, but older models share the EJ-series engine with its well-documented head gasket problem. Knowing the engine generation matters more than almost anything else here.
B
Yes, on newer engines — caution on older onesSame EJ-engine head gasket history as the Outback. The dividing line is the same: 2011 and earlier carries real risk.
Best years to buy used
2014–2018 (4th gen, FB engine)Subaru's FB-series engine replaced the problematic EJ and largely eliminated the head gasket issue. This is the safer engine generation to target for a used Forester.
2019–2023 (5th gen)Continues the FB engine's stronger reliability record with a more refined chassis and added safety tech. A strong modern used buy.
Years to think twice about
2000–2011 (EJ engine)Same head gasket failure pattern documented on the Outback from this era applies here. Coolant leaks internally or externally, leading to overheating. Get a pressure test before buying, or confirm the head gaskets have already been replaced.
💡 Check the coolant condition and ask for a combustion leak test before buying any pre-2012 Forester — it's the single most important check on these years.
Common problems to know
Head gasket failure (2000–2011, EJ engine): The defining issue. Check coolant condition and ask for service history.
CVT (2015+): Subaru's CVT is generally solid but change the fluid on schedule to avoid issues at high mileage.
Windshield cracking: Commonly reported across multiple years — not mechanical, but a known annoyance.
Bottom line
A 2014 or newer Forester with the FB engine sidesteps the head gasket risk entirely. Anything 2011 or older needs the coolant and head gasket history confirmed before you buy.
