Why it's a good car
This is the fifth-generation Outback, and the 2.5i is the mainstream version: a 2.5-liter FB25 boxer four (about 175 hp), the Lineartronic CVT, and Subaru's symmetrical all-wheel drive. The FB25 runs a maintenance-free timing chain, so the classic Subaru timing-belt anxiety does not apply here. It is a genuinely durable, well-understood all-weather wagon that runs to high mileage when maintained, and Subaru extended the CVT warranty to 10 years / 100,000 miles on 2010–2015 Legacy and Outback models — but on a 2015 car that ten-year clock has now run out, so you're the warranty now.
Does it have a timing belt or a timing chain?
A timing chain. The FB25 uses a maintenance-free chain, so there is no belt interval to budget for — a real advantage over older Subarus.
The things to check before you buy
- Oil consumption Earlier FB-series engines — especially 2013–2014 — drew a class-action settlement over piston rings that wore early and burned oil. The 2015 Outback is a later, revised-production car and falls outside that settlement, but some owners still report consumption, so check it: pull the dipstick cold and ask the seller flat out how often it needs topping up. A quart every 1,000 km or so is a heavy burner and a reason to walk on this engine.
- CVT Drive it from cold and again warm — it should pull away smoothly with no shudder, hesitation, or droning surge. Look for a fluid-service record (the "lifetime" fill is a myth) and know the 10-year / 100,000-mile CVT extension has now run out on 2015 cars — so there's no safety net, and any shudder, hesitation, or low-speed jerk is a reason to walk, not a quirk. A smooth, served CVT is a non-issue.
- Front wheel bearings The single most-reported item on this platform. At higher mileage expect one or more to be near replacement — listen for a cyclic hum or growl that changes with steering load. Cheap, but price it into your offer.
- Seal seepage The FB25 weeps a little oil from the cam-carrier and valve-cover seals with age — a light film is normal, an active drip onto the exhaust is worth pricing.
- Rust On a salt or winter car, check the rear subframe, rear control-arm areas, and brake lines for corrosion.
Open recalls — check the VIN, it’s free
Recalls are VIN-specific — you cannot assume the status from the model year. Look up any 2015 Subaru Outback 2.5i’s open recalls free by VIN at the U.S. National Highway Traffic Safety Administration (NHTSA); a Subaru dealer completes any open recall at no charge. Confirm the brake-light-switch recall of this era is completed; the FB25 engine’s oil-consumption history also makes on-time oil records worth looking for.
What a history report tells you — and what it doesn’t
On a car like this, the individual car’s history is most of the decision. A history report is a record of what got reported — title brands, reported accidents and damage, odometer readings over time, and service records where they exist. That is what separates a clean, maintained example from a salvage-title or flood car wearing the same badge.
What a history report is not is a forecast, and an absence of records is not proof of a clean past — plenty happens to a car that never gets reported. That is why the honest answer is always the pair: the documented history and an in-person inspection by a mechanic you trust, on the specific car.
What would make you walk
- Heavy oil consumption A confirmed quart every ~1,000 km points to a short block on this engine family — a walk-away, not a negotiation.
- A failing CVT Shudder, flare, or stored transmission codes.
- Structural rust Corrosion through the subframe, control-arm mounts, or brake lines.
