These are issues documented for the Subaru Forester in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Head Gasket Failure (Internal or External Coolant/Oil Leak)

Engine · severity: not established · confidence: 58/100 · 2 cited sources
Applies to: EJ25 / 2.5 - not every engine this model has been sold with
ⓘ Not yet individually classified

Symptoms to watch for

  • Slow, otherwise-unexplained oil or coolant loss/consumption
  • Overheating, in more advanced cases
  • Coolant contaminated with oil, or oil contaminated with coolant (a milky appearance on the oil dipstick/filler cap), on inspection
  • White or blue smoke from the exhaust, per independently-documented related oil-consumption reports on this same engine

What To Check

Not reliably detectable on a normal test drive in its early stages - a slow oil/coolant leak or early contamination is usually found on inspection (dipstick/filler cap check, cooling-system pressure test), not by driving the car. Overheating is a later-stage, more advanced symptom.
