2004 Subaru Baja — Known Trouble Spots
The systems that tend to fail first on the 2004 Subaru Baja, 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.
The 2.5L SOHC (EJ253) engine is infamous for external oil and coolant leaks from the head gaskets, typically occurring at the cylinder heads where they meet the block. This is often due to the original gasket material failing over time,…
The timing belt on the 2.5L SOHC engine is a critical maintenance item. Neglecting its replacement, along with the associated water pump and idlers, can lead to catastrophic engine damage (bent valves, piston damage) if it breaks.
Older Subarus, including the Baja, are prone to rust and corrosion, especially in areas exposed to road salt. Key areas include the rear subframe, rocker panels, rear wheel arches, and exhaust components, which can compromise structural…

Elevated Risk Zone
Beyond 120,000 miles, the Baja will require continuous attention to age-related wear and tear. If the head gaskets and timing belt haven't been done, they are almost certainly due. Rust on the undercarriage becomes a serious consideratio…
