VERDICT · SAME HEAD GASKET CONCERN AS THE OUTBACK

Subaru Forester (EJ25) 2.5L
is it a safe used buy?

A genuinely practical compact SUV sharing the same EJ25 engine, and that engine's well-documented head gasket history, with the related Outback.

How the engine fits this car

The Forester's compact SUV body is a reasonable, unstressed load for this engine mechanically — the risk, as with the related Outback, comes from the documented head gasket design concern detailed on the engine page.

Turbocharged XT versions were also offered on this generation — worth confirming which engine a specific car has, since the turbo version carries additional considerations beyond the naturally aspirated engine covered here.

Subaru Forester (EJ25)-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

  • Genuinely capable, practical compact SUV with real everyday versatility and all-wheel-drive security
  • A confirmed, repaired example (with the revised head gasket) is a meaningfully safer, well-understood buy
  • Strong independent specialist knowledge given how thoroughly this issue has been documented
  • Low purchase price reflects the issue's notoriety, which can work in a well-informed buyer's favour

WHAT TO WATCH

  • External head gasket coolant leak, detailed in full on the engine page, is a genuine and significant concern
  • Verifying repair completion requires real diligence, not just a general assurance from the seller
  • Resale demand has softened somewhat, reflecting broader buyer awareness of this issue
  • Age-related wear on suspension, electrics and interior trim is now a bigger practical factor than on newer cars

Pre-purchase checklist for this generation

This is non-negotiable: ask whether the head gasket has been proactively replaced with the revised design, and get documentation if so.

Check for a sweet coolant smell or visible seep near the lower edge of the cylinder head, the hallmark symptom.

Confirm which engine the specific car has if shopping for a turbocharged XT trim, since it carries additional considerations.
