2009 Subaru Forester 2.0L Diesel · PN59 XFD

The vehicle remains roadworthy but the maintenance history shows a clear worsening trend regarding structural and component degradation. While it passed the most recent test in November 2025 at 59,339 miles, the tester identified new advisories for nearside and offside front suspension arm bushes. This represents a progression from the 2024 test, which only flagged the rear sub-frame corrosion, indicating that the vehicle's underbody and suspension components are beginning to fail despite the low overall mileage. At 17 years old, the recorded mileage of 59,339 miles reflects an average of approximately 3,500 miles per year. This low usage pattern suggests limited mechanical wear on the engine and drivetrain but often accelerates the deterioration of rubber components and metalwork. The data shows consistent annual testing with mileage intervals of between 1,100 and 1,500 miles between 2021 and 2025. This slow accumulation means the vehicle likely sat stationary, which invites environmental-related corrosion rather than mileage-based fatigue. A buyer must conduct a thorough physical inspection of the rear sub-frame and underbody to assess the depth of the corrosion noted in 2024 and 2025. The tester specifically flagged corroded fuel pipes and the filler breather in the latest report, which poses a leak risk if the oxidation is allowed to perfor. Furthermore, the front suspension arm bushes require immediate attention for play, as they will soon affect handling stability. Given the history of corroded exhaust joints from 2023, the entire exhaust system should be checked for structural thinning to ensure no imminent failure.
