Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

Excessive oil use on the FB25 2.5 (piston rings)

Confirmed pattern

On the 2.5-litre FB25 engine used in the fifth-generation Outback (roughly 2009-2014), owners report the car burning a litre or more of oil between services, sometimes triggering the low-oil warning light. Subaru's own response in the US was to run an extended-warranty style oil-consumption test: if the engine used more than a set amount in a controlled test, it qualified for a short-block or piston-ring rebuild under goodwill cover. Typical mileage when it shows up is 30,000-60,000, and an out-of-warranty rebuild runs well into four figures.

Lineartronic CVT judder, hesitation and failure

Emerging

The Lineartronic CVT fitted from 2010 onward gets repeated complaints of a pause or clunk shifting from reverse to drive, shuddering under light throttle, and occasional total failure needing a full transmission replacement. In the US, Subaru extended CVT warranty cover for affected model years after a class-action settlement, which is a strong signal the problem is real even though it hasn't been formally acknowledged in the UK. A full transmission rebuild or replacement is one of the most expensive repairs an Outback owner can face.

EJ25 head gasket leaks

Pre-2009 (EJ25 engine) only

On the older 2.5-litre EJ25 engine, fitted up to around 2009, external head gasket leaks are a long-standing owner complaint, usually oil or coolant weeping from the gasket edge rather than internal mixing. It tends to show up from around 80,000-120,000 miles and a proper repair (removing the heads to fit updated gaskets) typically runs to four figures given the labour involved. It doesn't apply to the later FB-engined cars, which use a different gasket design.

Front suspension knocks and clunks

Partly in the MOT data

Owners report clunks and popping noises from the front end over bumps and on full-lock turns, usually traced to strut top mounts or suspension bushes wearing out earlier than expected, sometimes from 60,000 miles. This lines up with the measured MOT data, where suspension is the standout fault category for the Outback against other saloons and estates. The forums and the numbers agree on the area; they just don't always agree on which exact part is to blame.

Flat batteries and electrical gremlins

Disputed

A cluster of complaints, concentrated around the 2017 model year, describe batteries going flat or dying well before the usual 4-5 year mark, sometimes linked to parasitic drain from keyless entry or infotainment modules staying awake. Owners disagree on the cause, some blame poor short-trip charging habits rather than a car fault, but it's common enough to be worth checking. Replacement is cheap, £100-150, but repeated failures point at a wiring or module fault that costs more to chase down.

EyeSight camera recalibration after glass work

EyeSight-equipped cars only

Cars fitted with Subaru's EyeSight driver-assist system use a stereo camera pair mounted on the windscreen. Any windscreen replacement or even a knock to the mirror mount needs a dealer or specialist recalibration or the lane-keep and auto-braking features stop working properly, adding £150-300 on top of the glass itself. It's not a fault as such, just an easy-to-miss cost that catches buyers out on cars with a chipped or previously replaced windscreen.

Viewing one? Ask this

Built from the two sections above.

Check the oil level on the dipstick and ask for any oil top-up history between services. Regular top-ups or a warning light history points at FB25 piston-ring wear.
From cold, select reverse then drive and pull away gently, listening for a clunk or pause. A noticeable delay or shudder is the classic Lineartronic CVT complaint.
On pre-2009 EJ25 cars, check under the bonnet around the cylinder head edges for oil or coolant staining. Weeping stains mean a head gasket job is coming.
Drive over a speed bump or rough road and turn the wheel to full lock in a car park. Knocks or clunks from the front end suggest worn strut mounts or bushes, the area behind the model's MOT suspension pattern.
Check the battery's date sticker and ask if it's been replaced recently. A battery under 2 years old on an older car suggests a drain problem, not just age.
Ask if the windscreen has ever been replaced on an EyeSight-equipped car, and check the lane-keep warning light comes on and clears at startup. A replaced screen with no recalibration invoice means the safety systems may be out of alignment.
Pull the full MOT and service history rather than trusting a clean current test. Repeated same advisories or gaps around 60-100k miles line up with when these faults typically start.
