2010 Subaru Forester 2.0L Diesel · BT60 DWF

The vehicle maintains a roadworthy status, though the maintenance trend shows the first sign of emerging structural concern. The most recent test conducted in August 2025 at 83,291 miles identified a corroded rear sub-frame. While the tester determined the component was not yet seriously weakened to fail, this marks the first recorded defect in a period of four consecutive years of clean test results between 2021 and 2024. The mileage profile is characteristically low for a sixteen-year-old vehicle, averaging approximately 5,200 miles per year. Between August 2021 and August 2025, the car covered 18,361 miles, indicating consistent but light-duty usage rather than long-distance commuting. This low accumulation suggests less mechanical wear and tear on the drivetrain and engine, but low-mileage vehicles of this age often suffer from accelerated degradation of rubber components and the accumulation of surface oxidation, which likely explains the recent corrosion found on the sub-frame. A buyer must prioritise a thorough underbody inspection of the rear sub-frame to determine if the corrosion rate has accelerated since the 2025 advisory. Because the vehicle is a Subaru, structural integrity of the chassis and suspension mounting points requires critical attention, as rust in these areas can become progressive. Given the low mileage, the inspector should also check for hairline cracks in suspension bushes and perished seals, as these materials age out over time regardless of how many miles the vehicle has travelled.
