Subaru Legacy maintenance: the schedule, the costs, the traps
A midsize sedan with a gas powertrain. Below: the service intervals with real cost ranges, the repairs Legacy owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.
Service schedule
What it needs, and what that runs

Known repair windows
What Legacy owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
11.6-inch infotainment freezes/reboots (Starlink)
medium severity10,000-80,000 mi · $0-1,400
2020+ portrait touchscreen is a top complaint; laggy, reboots, HVAC controls locked; software updates or head-unit replacement
CVT service/repair
high severity70,000-140,000 mi · $4,000-7,500
Lineartronic CVT judder/whine; TR580/turbo variant costlier
Parasitic battery drain
medium severity20,000-80,000 mi · $300-900
DCM/telematics keeps 12V awake; repeat dead batteries

Operator notes
DISCONTINUED after 2025 (final Legacy built Sept 2025). 2.5L FB25 or 2.4L FA24 turbo (XT), CVT, timing CHAIN. Full-synthetic oil 6,000 mi/6 mo; severe 3,000-3,750 mi. Spark plugs 60k; long-life coolant ~137,500 mi. XT models recommend premium fuel.
When the smart money sells
On fleet math, a gas Legacy retires around 95,000 miles - but the exit window opens earlier here: CVT service/repair risk window ($4,000-7,500) opens ~70,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
