Subaru Legacy GT
Turbo boxer with 2.5L β 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 β the underrated turbo wagon/sedan
EJ255 turbo in a midsize: fast, unassuming, all-wheel drive. The Legacy GT is the sleeper nobody sees coming. Same engine as the WRX, more space, less attention.
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 clichΓ© 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
Rear subframe with poor factory paint corrodes through in salt regions. Can destroy control arm mounting points. Safety critical; recall issued for certain model years.
Recall WQK-47 also covers 2010β2014 Subaru: steel brake lines rust through from road salt splash. Safety critical defect.
First-generation Lineartronic CVT (TR580/TR690): valve body wear or infrequent fluid changes lead to chain slip. Costly repair; warranty extended to 10 years/100,000 miles.
Typical Subaru wear item. Wheel bearings fail earlier from corrosion in salt regions, rear axle most commonly affected. Replacement straightforward.
