A compact SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs Forester owners actually report, and the mileage windows worth buying ahead of - whether you are keeping it for yourself or putting it to work.
Service schedule
What it needs, and what that runs
| Interval | Service | Cost |
|---|---|---|

Known repair windows
What Forester 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.
Engine oil consumption (FB25)
medium severity40,000-100,000 mi · $150-2,500
FB25 historically the poster-child for Subaru oil burning (piston-ring TSB/class action on 2014-2018); improved on later/redesigned engines but watch levels
CVT service/failure
high severity70,000-140,000 mi · $4,000-7,500
Lineartronic CVT judder/whine at higher mileage
Windshield cracking (EyeSight)
medium severity10,000-70,000 mi · $1,000-1,700
Forester is especially notorious for cracked windshields; ADAS recalibration required
Wheel bearings
medium severity60,000-120,000 mi · $350-650 per corner
Common Subaru wear item, growl at speed
AC condenser damage
medium severity40,000-100,000 mi · $650-1,250
Debris punctures of exposed condenser
Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Forester at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $170 | $14 |
| 3 years | 36,000 mi | $785 | $22 |
| 5 years | 60,000 mi | $1,760 | $29 |
| 7 years | 84,000 mi | $2,100 | $25 |
| 10 years | 120,000 mi | $3,820 | $32 |
| 15 years | 180,000 mi | $5,580 | $31 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this Forester is known for is CVT service/failure from about 70,000 miles ($4,000-7,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
2.5L FB25 BOXER (redesigned 6th gen from 2025), CVT, timing CHAIN. A separate 2.5L series-parallel Hybrid trim also exists. Full-synthetic oil 6,000 mi/6 mo; severe 3,000-3,750 mi. Spark plugs 60k; long-life coolant ~137,500 mi. Redesigned gen has limited long-term field data.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a gas Forester retires around 95,000 miles - but the exit window opens earlier here: CVT service/failure 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.
