Top Risk Areas
The systems that tend to fail first on the 2009 Subaru Legacy, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
External coolant and/or oil leaks from the cylinder head gaskets are widespread on the 2.5L SOHC EJ253 engine, often leading to slow coolant loss or oil seepage. If left unaddressed, coolant loss can cause overheating and serious engine…
Leaks from the power steering pump, hoses, and steering rack are common as seals and lines degrade over time. This leads to low fluid levels, groaning noises, and potential loss of power assist.
Premature failure of front and especially rear wheel bearings is a known issue, causing a distinct humming or grinding noise that worsens with speed. This is a common wear item that requires replacement for safe operation.
