What is the 2003-2006 Subaru Baja EJ25 Head Gasket Failure?
The Subaru Baja's 2.5L EJ25 naturally-aspirated engine suffers from the same chronic head gasket failure that affects all EJ25-equipped Subarus. The composite gaskets degrade over time, typically between 80,000-150,000 miles, causing external oil and coolant leaks. The Baja's eng… Repairs typically run $1,500-$2,800. Severity: high.
What is the 2004-2006 Subaru Baja Turbo Baja (EJ255) Turbocharger Failure and Banjo Bolt Screen Restriction?
The Baja Turbo uses the EJ255 turbocharged engine with a TD04 turbocharger. The oil supply banjo bolt that feeds the turbo contains a small mesh screen filter that can clog over time, restricting oil flow to the turbo bearings. Oil starvation causes the turbo to fail prematurely,… Repairs typically run $50-$2,500. Severity: high.
What is the 2003-2006 Subaru Baja Rear Strut Tower Rust and Structural Weakening?
The Baja's rear strut towers (located under the bed) are highly susceptible to rust, which can compromise the structural integrity of the suspension mounting point. Water and debris accumulate around the strut towers due to the bed design, and inadequate factory rustproofing allo… Repairs typically run $300-$2,000. Severity: high.
What is the 2003-2006 Subaru Baja Bed and Rear Quarter Panel Rust?
The Baja's composite bed and steel rear quarter panels are prone to significant rust, particularly in salt-belt states. The junction between the composite bed panels and steel body structure traps moisture and road salt, accelerating corrosion. The rear wheel arches, bed floor se… Repairs typically run $200-$3,000. Severity: medium.
