Reliability, common problems and owner reviews for the Subaru Legacy / Outback 2.5i (FB25, 2012–2014). Check this before you buy used.
The FB25 replaced the EJ25 and dropped its head-gasket reputation — a more modern, chain-driven boxer that's the sensible 2.5 to buy. Its known trait is oil consumption from first-run low-tension piston rings (typically after higher mileage). Otherwise a smooth, durable engine for the heavy AWD wagon. Check oil level and consumption history; keep the CVT and AWD fluids fresh.
