THINK TWICE

The Lineartronic CVT is the recurring powertrain risk across the models that share it: POWER TRAIN is 11% of Outback (644/5,895), 12% of Legacy (182/1,457), 7% of Impreza (91/1,388) and 15% of 2019 Ascent (86/555) federal complaints, and the narratives repeatedly describe the CVT shuddering, hesitating, jerking or whining and then losing drive power. It is largely a warranty/class-action matter, not a recall (the exception is the Ascent drive-chain recall).

Check — Test-drive deliberately: from a stop and at light throttle, and holding a steady 20-45 mph, feel for shudder, hesitation, jerk or whine, and any hard or delayed engagement. Check the CVT fluid (clean, not burnt), and ask for CVT service, reprogram, or replacement history and any remaining extended CVT coverage.

On the 2010-2018 Outback and Legacy the Lineartronic CVT is known for a low-speed shudder and hesitation, often traced to the torque converter or valve body: 146 POWER TRAIN complaints across the two describe shudder or hesitation, and owners widely cite valve-body service, an extended CVT warranty (commonly described as 10 years/100,000 miles), and a class-action settlement. These complaints cluster mid-to-late life (POWER TRAIN median ~93k miles Outback, ~100k Legacy), so a high-mileage car may already be at or past that coverage, and a CVT replacement is a $4,000-8,000 event.

Check — On a test drive, accelerate gently and hold a light cruise and feel for a shudder or vibration through the driveline; a software reprogram can mask it. Check CVT fluid condition, ask whether the valve body or CVT was ever serviced or replaced, and confirm whether any extended CVT coverage still applies to the VIN.

The SOHC EJ25's defining flaw is an external head-gasket leak: the gasket seeps oil and/or coolant at the head-to-block seam, classically once the car is well used (the corpus median on these complaints is ~86k miles, and it is a near-certainty by ~100k+ on an un-serviced example). It is the best-known Subaru issue of this era -- 237 federal complaints across the SOHC EJ25 models (Outback, Forester, Legacy, Impreza, MY2000-2011) name a failed head gasket, led by the Outback (120). It is usually a slow external seep rather than a sudden failure, but a correct repair -- heads off, resurfaced, timing components refreshed -- runs well into four figures, so it is a price-negotiation item more than a walk-away.

Check — Look for oily or crusty coolant residue where the heads meet the block, low or recently topped-off coolant, an oil sheen in the coolant or a milky film under the oil cap, and any overheating history. Ask for records of a prior head-gasket job and whether the timing belt, tensioner, and water pump were done with it.
