The 2007 Legacy 2.5L is a solid daily driver undermined by Subaru's notorious EJ25 head gasket weakness and a fragile automatic transmission oil cooler. Most examples will need expensive engine work before 120k miles if not already done.
EJ25 Head Gasket Failure (External Oil Seepage)
Common · high severity
Typical onset: 80,000-120,000 mi
Symptoms: Oil seepage visible at block/head seam on both sides, Slight coolant loss over time without visible leaks elsewhere, Oil drips accumulating on exhaust causing burning smell, Eventual overheating if coolant leak progresses
Fix: Both head gaskets, resurface heads, timing belt/water pump/pulleys while apart, new coolant. 12-16 labor hours depending on shop efficiency. This is the big one—most owners see it once in the vehicle's life.
Estimated cost: $2,200-3,500
Transmission Oil Cooler Line Rupture (Auto only)
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Sudden trans fluid spray under vehicle while driving, Transmission overheating or slipping immediately after leak starts, Red ATF puddle under engine bay, Complete loss of drive if ignored for even a few miles
Fix: Replace both metal hard lines (they corrode from inside out). Flush cooler, inspect for debris, refill ATF. If driven after rupture, internal clutch damage likely—add $3k-5k for rebuild. 3-4 hours if caught early.
Estimated cost: $600-1,200
Transmission Mount Collapse
Common · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Vibration at idle in gear, Visible sag of transmission tailshaft—check from underneath, Driveline shudder on acceleration
Fix: Replace rear transmission mount (rubber deteriorates). Often done alongside exhaust work since access overlaps. 1.5-2 hours.
Estimated cost: $250-450
Takata Airbag Inflator Recall (Passenger Side)
Occasional · high severity
Symptoms: No symptoms—silent safety defect, Inflator can rupture violently in crash, sending metal shrapnel into cabin, Affects vehicles in high-humidity climates more severely
Fix: Free recall repair at any Subaru dealer—replacement inflator takes 1-2 hours. Check VIN at NHTSA.gov before purchase. Some owners still driving unrepaired examples.
Estimated cost: $0 (recall)
Brake Line Corrosion (Salt-Belt States)
Occasional · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Soft or spongy brake pedal, Visible rust perforation on steel hardlines near rear subframe, Brake fluid leak at line fittings or mid-section, Complete pedal loss if line ruptures while driving
Fix: Replace affected steel lines—often all four corners if one fails. Flush system, bleed thoroughly. 4-6 hours depending on corrosion severity and seized fittings.
Estimated cost: $800-1,500
Alternator Bearing Failure
Occasional · medium severity
Typical onset: 110,000-150,000 mi
Symptoms: Grinding or whining noise from front of engine, Battery warning light flickers or stays on, Dimming headlights at idle, Eventually no-start when battery drains
Fix: Replace alternator. Tight working space on H4—requires removing air box and sometimes AC lines repositioned. 2-3 hours.
Estimated cost: $500-800
Owner tips
If buying used, verify head gaskets already done or budget $3k immediately—it's when, not if
Inspect trans cooler lines at every oil change; surface rust is normal but flaking/pitting means replace proactively
Use Subaru Coolant Conditioner additive at every flush to extend next head gasket interval
Check recall status for Takata airbag and ignition switch—both are safety-critical freebies
Buy one only if head gaskets are documented as replaced with OEM multi-layer gaskets and timing components; otherwise you're inheriting a $3k job within a year.
