Head Gaskets:
While less prevalent in the EJ253 than earlier generations, head gasket leaks can still occur, especially with overheating. The EZ30D is generally more robust in this regard.
Oil Leaks:
Rear main crankshaft seal and valve cover gaskets can develop leaks over time.
Suspension Wear:
Sway bar end links and bushings can wear out, leading to clunking noises. Struts may also require replacement at higher mileage.
Catalytic Converter:
Can become clogged over time, affecting performance and emissions.
Automatic Transmission:
The 4EAT is generally reliable but requires regular fluid changes to maintain longevity.
Subaru Heritage:
Founded in 1953, Subaru (a division of Fuji Heavy Industries, now Subaru Corporation) is known for its horizontally-opposed Boxer engines and standard Symmetrical All-Wheel Drive systems, originating from their aviation roots.
Legacy Outback Origin:
The Outback originated as a trim level of the Subaru Legacy sedan and wagon, introduced in 1995 as the 'Legacy Outback Sport'. It gained increased ride height and rugged body cladding, effectively creating the 'crossover' segment before the term was widely adopted.
Gen 4 Context:
The 4th generation (BP/BL) Legacy Outback, launched for the 2005 model year, continued this formula with a more refined chassis, updated styling, and the introduction of the larger 3.0L H6 engine option. The 2008-2009 models represent the facelifted versions of this generation, featuring revised styling and updated features.
Manufacturing Location:
Gunma Plant, Japan
