Common Problems & Known Issues

The 2009 Impreza with the 2.5L naturally-aspirated EJ253 engine is a solid daily driver, but shares the infamous EJ-series head gasket weakness and can develop CVT or 5-speed manual transmission issues depending on configuration. Budget for major engine work if buying high-mileage.

Head Gasket Failure (EJ253 Engine)

Common · high severity
Typical onset: 90,000-130,000 mi
Symptoms: External oil seepage at block/head joint, Coolant loss with no visible external leak, White exhaust smoke on cold start, Overheating under load, Milky oil cap residue in severe cases
Fix: Both head gaskets, head resurfacing, timing belt/water pump/pulleys while in there, all coolant hoses. 12-16 labor hours. Use MLS gaskets, not OEM composite. Many shops do timing components, valve cover gaskets, and cam/crank seals at same time since engine is apart.
Estimated cost: $2,200-3,500

CVT Transmission Judder and Failure (CVT models)

Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Shuddering on acceleration from stop, Transmission slipping or failing to engage, Whining or grinding noises, Harsh engagement when shifting to Drive, Check engine light with CVT-related codes
Fix: Early judder sometimes responds to fluid flush with Subaru High Torque CVT fluid, but internal clutch pack wear or valve body failures require transmission replacement or rebuild. Subaru extended warranty covered some units to 10yr/100k. 8-12 labor hours for R&R.
Estimated cost: $3,500-5,500

Piston Ringland Failure (less common on NA 2.5L, more on turbo variants)

Rare · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Sudden loss of compression in one cylinder, Loud rattling/knocking from engine, Blue smoke on startup, Misfires and rough idle, Metal shavings in oil
Fix: Requires engine teardown, piston replacement, likely bore honing or cylinder sleeve, new rings, bearings inspection. Often more cost-effective to install used short block. 18-24 labor hours for full rebuild; 10-14 for short block swap.
Estimated cost: $3,000-6,000

Wheel Bearing Noise and Failure

Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Growling or humming that increases with speed, Noise changes when cornering left vs right, Vibration through steering wheel or floorboard, ABS light in some cases
Fix: Replace hub/bearing assembly, one corner at a time typically. Rears tend to go first. 1.5-2.5 labor hours per corner. Use OEM or quality aftermarket (Timken, NSK); cheap bearings fail quickly.
Estimated cost: $250-450 per corner

Front Strut Mount / Bearing Clunk

Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps from front end, Steering feels notchy or catches when turning at low speed, Rattling on rough roads, Uneven tire wear in some cases
Fix: Replace strut mount and bearing plate, inspect strut for leaks while in there. Often done in pairs. 2-3 labor hours for both sides including alignment check.
Estimated cost: $400-700

Brake Light Switch Failure (Recall Campaign)

Occasional · medium severity
Symptoms: Brake lights stay on constantly, Brake lights won't illuminate, Cruise control won't engage, Shift interlock may prevent shifting out of Park, Battery drain if lights stuck on
Fix: Replace brake light switch at pedal assembly. Covered under recall WTF-73. 0.5 labor hours if not recall-eligible.
Estimated cost: $80-150

Exhaust Manifold / Y-Pipe Rust and Cracking

Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Ticking or exhaust leak noise from engine bay, worse on cold start, Smell of exhaust in cabin, Check engine light with lean codes or O2 sensor codes, Visible rust perforation on exhaust components
Fix: Replace cracked manifold or Y-pipe section. Studs often break during removal on high-mileage engines—factor extra time for extraction. 3-5 labor hours depending on which section fails. Aftermarket headers an option for performance builds.
Estimated cost: $600-1,200
Owner tips
  • Change CVT fluid every 30k-40k with OEM Subaru High Torque fluid—not lifetime fluid despite what manual says
  • Watch coolant level religiously; sudden drops are early head gasket warning
  • Use quality 5W-30 synthetic and change every 5k miles—helps prolong ringland life
  • Inspect for oil seepage around head gasket mating surface at every oil change after 80k miles
  • Replace timing belt, water pump, and all pulleys at 105k miles or 10 years—interference engine will self-destruct if belt breaks
Buy one under 90k miles with documented timing belt service and no head gasket history, or budget $2,500-3,500 for eventual engine work—solid otherwise, but the EJ253 will nickel-and-dime you past 100k.
