Subaru Legacy 3.6R

EZ36 3.6L H6 256 hp Automatic All-wheel drive Sedan 2015–2019
✔ Good Choice
Engine EZ36 ✔ Good Choice 7,250–14,500 €

Six-cylinder boxer: 3.6L naturally aspirated, smooth and torquey. Significantly more reliable than the EJ four-cylinders. Oil leaks at valve covers and timing chain cover at higher mileage are the main concerns. No head gasket issues. 200k+ mile lifespan realistic.

Fun Factor? Decent

Six-cylinder Legacy — refinement meets midsize

H6 boxer: effortless, quiet, reliable. The most relaxed Legacy. Higher consumption, but unique character.

Engine Weaknesses 3

!! Timing Chain Tensioner Worn

Plastic timing chain tensioner wears after 90,000+ miles and can no longer maintain adequate chain tension. Starts with cold-start rattle, can progress to timing chain jump. Expensive repair due to many bolts on the chain cover.

Symptoms: Rattling on cold start, loud chain noise, misfires at high mileage

1,500–3,200 € from 150,000 km
! Oil Leaks at High Mileage

Valve cover gaskets and timing chain cover become leaky at higher mileage. Typical for boxer engines with many sealing surfaces. Not a critical weakness, but noticeable cosmetically and by smell.

Symptoms: Oil spots under engine, oil smell when engine is hot

800–2,000 € from 120,000 km
! Serpentine Belt Tensioner Worn

Belt tensioner spring fatigues after approximately 75,000-95,000 miles. Loss of tension causes slipping, squealing, and in severe cases, failure of the alternator and A/C compressor.

Symptoms: Squealing from engine bay, A/C failure, battery warning light, overheating

250–400 € from 130,000 km

Vehicle Weaknesses 4

!! Brakes Brake Line Corrosion

Steel brake lines can corrode in salt regions. Less systematic than older generations but inspect on any BN from salt-belt states before purchase.

400–900 € from 120,000 km
!! Gearbox CVT Judder (Lineartronic)

Revised Lineartronic CVT — significantly more reliable than BM, but neglected fluid maintenance leads to judder. Warranty extended to 10 years/100,000 miles.

4,000–7,000 € from 100,000 km
! Suspension Wheel Bearing Fails Early

Multiple reports of wheel bearing failure below 50,000 miles. Subaru internal warranty extension to 5 years/60,000 miles. Repeated failure on the same vehicle possible.

300–500 € from 50,000 km
! Electronics EyeSight System Failure

EyeSight shuts down in cold, fog, or after windshield cleaning. BLS failure can permanently disable EyeSight. Software update usually helpful.

0–500 € from 50,000 km
