Common Problems & Known Issues

The 2014 Legacy is a solid midsize sedan, but the 2.5L H4 engine suffers from a well-documented oil consumption problem that can destroy the engine if ignored. The CVT transmission is generally reliable in this generation but has specific cooler line and mount issues that need attention.

Excessive Oil Consumption / Piston Ring Failure (2.5L H4)

Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Burning more than 1 quart per 1,000-1,500 miles, Blue smoke from exhaust on startup or acceleration, Low oil warning light between oil changes, Carbon buildup on intake valves causing rough idle and hesitation
Fix: Subaru issued extended warranty coverage (8 years/100k miles) for this defect, but many 2014s are now out of coverage. Proper fix requires short block replacement (piston rings alone rarely solve it long-term). 18-24 labor hours for short block swap including break-in procedure. Some owners attempt cleaning intake valves and living with frequent top-offs as a Band-Aid.
Estimated cost: $5,500-7,500

CVT Transmission Oil Cooler Line Failure

Occasional · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Transmission fluid leaking from front of vehicle near radiator, Pink or red fluid puddles under car, Transmission overheating warning on dash, Slipping or erratic shifting after leak begins
Fix: The rubber cooler lines from CVT to external cooler deteriorate and crack. Must replace both lines (never just one) and top off CVT fluid with correct Subaru High Torque fluid. 2-3 labor hours. Critical repair—running CVT low on fluid will destroy it ($7k+ replacement).
Estimated cost: $400-700

Rear Transmission Mount Failure

Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Vibration at idle that disappears when shifted to Neutral, Visible tearing or separation of rubber mount when inspected from below
Fix: The rear trans mount takes heavy load and tears. Replacement requires supporting transmission and swapping mount. 1.5-2 labor hours. Use OEM Subaru part—aftermarket mounts fail quickly.
Estimated cost: $250-400

Head Gasket Weeping (Early Detection)

Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Slight coolant seepage visible at engine block seam below heads, Faint coolant smell after driving, Slow coolant loss with no visible external leaks, No overheating or milky oil (yet)
Fix: The 2014 uses multi-layer steel head gaskets which are far better than older Legacy gaskets, but external weeping still occurs. Catch it early before it becomes internal failure. Full head gasket job requires engine removal on H4, 16-20 labor hours. Always resurface heads, replace timing components, water pump, and coolant hoses while in there.
Estimated cost: $2,800-4,200

Takata Airbag Inflator Recall Issues

Common · high severity
Symptoms: Recall notice from Subaru (check VIN at NHTSA site), Passenger airbag may not deploy properly or deploy with excessive force, No symptoms visible to driver—purely precautionary recall
Fix: Six separate recalls for passenger-side airbag inflators. Subaru dealers perform replacement at no cost. Takes 1-2 hours. CRITICAL: verify this was completed before buying used. Some dealers still have part shortages—confirm availability before purchase.
Estimated cost: $0 (recall repair)

Windshield Wiper Motor Linkage Failure

Occasional · low severity
Typical onset: 90,000-130,000 mi
Symptoms: Wipers move slowly or only partially across windshield, Clicking or grinding noise from wiper area, Wipers stop in middle of windshield, One wiper moves while other hesitates
Fix: Linkage bushings wear and the motor struggles. Usually requires motor assembly and linkage replacement together. 2-3 labor hours. Covered by recall if failure meets specific criteria—check recall status first.
Estimated cost: $350-600
Owner tips
  • Check oil level every other fill-up on 2.5L engines—oil consumption kills these motors if ignored
  • Change CVT fluid every 30,000-40,000 miles with Subaru High Torque fluid only, regardless of 'lifetime fill' claim
  • Inspect CVT cooler lines annually after 80k miles—catching a leak early prevents transmission destruction
  • Run compression and leak-down test on 2.5L engines before purchase if over 70k miles
  • Verify Takata airbag recall completion—dealership records should show it
Buy the 3.6L H6 without hesitation; avoid 2.5L H4 models unless oil consumption history is documented clean or short block was already replaced under warranty.
