    Money

    Repair Costs

    Dealer, independent-specialist, and DIY pricing for every major Subaru repair — head gaskets, CVTs, clutches, timing belts, wheel bearings — with OEM part numbers so you can cross-shop without getting a knockoff.

    Reliability

    Reliability & Common Problems

    Model-by-model reliability data pulled from owner reports and NHTSA complaints: oil consumption, head gaskets, CVT shudder, differential whine, and what actually breaks past 100,000 miles.

    Powertrain

    Engines & Drivetrains

    EJ, FA, FB, EZ, Lineartronic CVT, VTD, DCCD — how every Subaru boxer engine and AWD system is built, how it fails, and what the permanent fix costs. Includes engine-family teardowns and drivetrain deep-dives.

    Performance

    WRX & STI

    Ringlands, rod bearings, RTV pickup-tube clogs, 6MT clutches, DCCD solenoids — the turbo Subaru knowledge every WRX and STI owner needs before the next boost pull or track day.

    SUV

    Forester

    FB25 oil consumption, windshield cracking, rear differential whine, CVT service intervals — Forester issues documented from the SG generation through the current SK and SL, with year-by-year fixes.

    Wagon

    Outback

    EJ25 head gaskets, Lineartronic CVT shudder, X-Mode transfer-clutch failure, and the real cost of keeping an Outback past 150,000 miles across every generation from the BE/BH to the current BT.

    Compact

    Crosstrek

    FB20 oil consumption, CVT shudder on early XV Crosstreks, and the lightweight ATS AWD system that makes the Crosstrek the most-cross-shopped Subaru — plus what to check before buying used.

    Classic

    Vintage & JDM

    GC and GD-chassis Impreza, first-gen Legacy GT, EJ257 rod bearings, BRZ FA20 valve springs, and the JDM-market oddities — knowledge for the classic and enthusiast Subaru world.
