Subaru Legacy GT
Turbo boxer with 2.5L — the WRX engine of the GR/GV era. Same ringland vulnerability as the EJ257 (cast iron pistons with thin ringlands), but slightly less boost from the factory. Oil pickup tube crack, rod bearing failure, and timing belt are the three big concerns. Class action for 2012-2017 models extended warranty to 8 years/100k miles.
Legacy GT sedan — the sleeper nobody sees coming
EJ255 short block with STI heads from the factory. Same power as the WRX, more space, no sticker. Actually slightly faster than the 2.0 WRX stock-for-stock. The Spec B (STI six-speed, Bilstein suspension) is the bargain of the decade: ~1,400 US units, priced $10-20k. Steering is numb, the car won't rotate like a WRX — but anyone looking for a fast daily that doesn't attract attention: here.
Engine Weaknesses 5
Cast iron pistons with thin ringlands crack under detonation (knock). Causes: poor fuel quality, bad tuning, high exhaust gas temperatures. The EJ cliché alongside the head gasket.
Symptoms: Misfires at idle after high-load driving, increasing oil consumption, blue smoke
Class action for 2012-2017 WRX/STI: extended warranty to 8 years/100k miles. Oil starvation from boxer sloshing or neglected oil level as primary cause.
Symptoms: Knocking noise, oil pressure warning, metal particles in oil
Identical problem to EJ205: brazed joint cracks from vibration. No recall despite known issue since 1996.
Symptoms: Sudden oil pressure drop, engine noise, oil pressure warning light
Timing belt replacement every 105k miles mandatory. Same interference risk as all EJ engines.
Despite MLS gasket from the factory, the head gasket can fail under overheating or neglected maintenance. Less systematic than the EJ253 NA, but not immune.
Symptoms: Overheating under load, coolant loss, white smoke
Vehicle Weaknesses 4
Recall WQK-47 (2005–2014 Subaru): steel brake lines rust through from road salt. Brake fluid loss increases stopping distance — crash risk. Free repair at dealer.
Front control arm hanger brackets corrode from road salt. Along with brake lines, the most significant corrosion issue on this generation. Safety critical.
Known issue 2005–2009: dashboard becomes sticky-shiny from heat and humidity and creates glare in the windshield. Subaru extended warranty to 10 years.
Known BL/BP issue: rear wheel bearings fail prematurely. Subaru extended warranty to 100,000 miles. Repeated failure on the same vehicle documented.
