Known problems on the 2011 Subaru Forester

FB20 / FB25 oil consumption $1,200–$3,500 to fix

The FB 'boxer' engines of this era burn oil — often a quart every 1,000–1,200 mi — from a piston-ring design later revised. Subaru settled a class action and did ring replacements under an oil-consumption test.

Check for: Ask to see oil level now; ask the seller how often they add oil. A ring-replacement or an oil-consumption test on record means it was addressed.

Basis: Subaru oil-consumption class-action settlement; TSB 02-157-14

EJ25 head gaskets $1,400–$2,800 to fix

The naturally-aspirated EJ25 (especially SOHC) is known for external head-gasket seepage — coolant or oil weeping at the head-to-block seam, and overheating if ignored. A near-universal job on high-mile examples.

Check for: Look for crusty residue at the front corners of the engine where the heads meet the block, a low coolant reservoir, or a sweet smell. A documented head-gasket job (with timing belt) is a plus, not a minus.

Basis: Widespread NHTSA complaints; Subaru TSBs; well-documented generational issue

Known patterns for this year and model, not findings about one car. A well-kept example may already have had the fix. Costs are rough US shop prices.
