2011 Subaru Forester 2.0L Diesel · CV11 DDX

Persistent structural corrosion and recurring suspension component deterioration define the mechanical profile of this Subaru Forester, with the most recent test on 23 June 2026 showing a passed result despite ongoing advisories. The vehicle exhibits a documented history of rear sub-frame corrosion that has been flagged in every recorded test since at least 2023. While the sub-frame has been noted as not seriously weakened, the presence of this advisory across multiple years indicates a progressive issue. Furthermore, the suspension system shows signs of cumulative wear, moving from worn bushes and pins in 2023 to more significant deterioration of ball joint dust covers and corroded rear coil springs and shock absorbers in the 2025 and 2026 inspections. The recorded mileage of 86,348 miles against a 2011 registration represents an average annual accumulation of approximately 5,757 miles. This low annual mileage suggests the vehicle has been used sparingly over its fifteen-year lifespan. From a mechanical standpoint, such low usage can often correlate with the types of issues observed in the MOT history, where components like suspension bushes, shock absorbers, and brake discs may suffer from environmental degradation and corrosion due to infrequent movement and exposure, rather than high-frequency mechanical wear. A prospective buyer should pay close attention to the underside of the vehicle, specifically the rear sub-frame and the rear coil springs. Given the repeated advisories regarding sub-frame corrosion and the 2025 report of corroded rear coil springs, it is essential to inspect these areas for any signs of structural scaling or significant rust that could compromise integrity beyond the current advisory status. On a test drive, listen for any metallic clunking or knocking sounds from the rear of the car when travelling over uneven surfaces, which could indicate that the corroded coil springs or worn shock absorber bushes are affecting ride quality or stability. The suspension and braking systems also require scrutiny based on the recent history of deteriorating ball joint dust covers and previous reports of binding brakes and worn discs. During the test drive, pay attention to the steering response and any pulling to one side, which may be linked to the nearside front suspension component issues. Additionally, monitor the brake pedal feel for any pulsation or judder, and listen for any scraping or grinding noises that might stem from the previously noted pitted or scored rear brake discs. The deterioration of the ball joint dust covers is a specific point of concern, as failure of these covers can lead to premature joint failure and more significant steering or suspension instability.
