The 2009 Outback XT pairs Subaru's capable EJ255 turbocharged boxer with a 5-speed automatic that's proven fragile under boost. Head gaskets, ringland failures, and transmission oil cooler lines define the ownership experience—budget for major work if buying high-mileage.
Ringland Failure (Piston #4 Cracked Ringlands)
Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Sudden misfire on cylinder #4, flashing CEL, Loss of compression confirmed by leak-down test, White smoke from exhaust under load, Metallic rattle at cold start if debris circulates
Fix: EJ255 is notorious for cracked ringlands on piston #4 due to detonation and overboosting. Requires short block replacement or full engine rebuild—pulling motor, machining deck if needed, new pistons/rings/bearings, reassembly. 18-24 labor hours depending on shop efficiency and parts availability.
Estimated cost: $4,500-7,500
Head Gasket Failure (External Oil/Coolant Leaks)
Common · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Oil seepage visible at head/block mating surface, Coolant weeping from cylinder head perimeter, Slight overheating or coolant loss over time, No internal combustion gases in coolant (yet)
Fix: Classic Subaru external head gasket weep. Requires engine-out or in-chassis top-end teardown, resurface heads if warped, new multilayer steel gaskets, timing components, water pump while apart. 14-18 hours labor. Not as catastrophic as ringland failure but neglect leads to overheating.
Estimated cost: $2,800-4,200
Transmission Oil Cooler Line Failure
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Sudden transmission fluid puddle under vehicle, Transmission slipping or refusing to engage after fluid loss, Burnt ATF smell, Fluid sprayed onto exhaust components
Fix: The steel braided cooler lines corrode at crimped fittings or wear through on subframe. Failure dumps 9+ quarts of ATF in seconds—catastrophic if driven dry. Replace both cooler lines preventively, flush system, refill. 2-3 hours labor if caught early; if transmission starved, add rebuild cost.
Estimated cost: $400-800 (lines only); $3,500-5,000 if transmission damaged
Symptoms: Vibration/shudder at 40-50 mph under light throttle, Delayed or harsh 2-3 upshift, Slipping between gears under boost, Burnt ATF smell, metal shavings in fluid
Fix: The 5EAT wasn't built for sustained turbo torque. Torque converter lockup clutch wears, valve body solenoids stick. Early intervention: fluid/filter service with Subaru HP ATF may buy time. Once slipping: transmission rebuild or replacement. 8-12 hours R&R plus rebuild labor.
Estimated cost: $2,800-4,500
Turbocharger Wastegate Rattle & Boost Control Issues
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Metallic rattle at idle or light throttle (wastegate actuator rod loose), Overboost or underboost codes (P0243, P0245), Sluggish acceleration or surging, Smoke from exhaust if seals failing
Fix: IHI VF40 turbo wastegate actuator arm wears, causing rattle and inconsistent boost. Also prone to oil seal leakage. Often solvable with actuator rebuild kit or used turbo swap. Turbo R&R is 4-6 hours; if replacing with reman unit, add core charge.
Estimated cost: $800-1,800
Rear Transmission Mount Collapse
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunk when shifting from Park to Drive/Reverse, Vibration transmitted through chassis under acceleration, Visible drooping of transmission tailhousing
Fix: Rubber mount deteriorates, allowing excessive drivetrain movement. Inspect from underneath; replace with OEM or polyurethane upgraded mount. 1-1.5 hours labor on a lift.
Estimated cost: $200-350
Crank/Cam Position Sensor Failures Leading to No-Start
Occasional · medium severity
Symptoms: Intermittent no-start, cranks but won't fire, Stalling at operating temperature, CEL with P0335 (crank sensor) or P0340 (cam sensor), Starts fine when cold, fails when hot
Fix: Heat-related sensor failures common on EJ engines. Crank sensor behind crank pulley (2 hours), cam sensors on valve covers (1 hour each). Diagnose with scanner live data—RPM signal dropout confirms fault.
Estimated cost: $250-500
Owner tips
Change ATF every 30k with Subaru HP fluid—5EAT cannot tolerate universal ATF
Replace transmission cooler lines preventively at 80k-100k; failure is not 'if' but 'when'
Use 91+ octane fuel religiously; detonation kills ringlands on these EJ255 engines
Compression test and leak-down test before purchase—$150 inspection saves $6k engine bill
Budget $1,000/year for 'Subaru tax' beyond 100k miles; these are not Honda-reliable
Only buy if under 80k miles with full service records and a $3k repair fund—ringland failures and transmission issues make high-mileage examples a gamble.
