Reliability, common problems and owner reviews for the Subaru XV 1.6i / 2.0i Boxer (FB16 / FB20). Check this before you buy used.
The naturally-aspirated FB Boxer petrols (1.6 and 2.0, shared with the Impreza and Forester, often with the e-Boxer mild-hybrid) give the XV Subaru's signature symmetrical all-wheel-drive grip. They're chain-driven and fundamentally durable, but carry the boxer-engine traits: they can use a little oil (monitor the level), the horizontally-opposed layout makes some jobs (spark plugs, head gaskets on older designs) labour-heavy, and the Lineartronic CVT needs correct fluid and gentle treatment. Performance is modest — the naturally-aspirated boxer works hard in the crossover — but with oil monitoring and CVT care it's a dependable, genuinely capable AWD car. Buy on oil and CVT history.
