2017 Subaru Forester 2.0L Diesel · AE17 OKN

The Subaru Forester presents a stable and improving maintenance trend, culminating in a clean pass on 10 March 2026 at 46,863 miles with zero defects recorded. That is a strong result for a nine-year-old vehicle. The record shows a clear trajectory from minor structural advisories and tyre defects in earlier years toward full compliance in the most recent test, suggesting the previous owner addressed outstanding issues rather than ignoring them. Mileage accumulation is low, averaging roughly 5,207 miles per year over nine years. The 2026 test recorded 46,863 miles, just one mile above the 46,863 figure on file, indicating the vehicle has effectively stood still since March. The jump from 42,582 miles in March 2025 to 46,863 miles in March 2026 accounts for 4,281 miles in the final year, which is modest but not negligible. The earlier intervals show steady annual use of around 2,000 to 2,300 miles, consistent with short commutes or intermittent use rather than high-mileage touring. The 2023 failure flagged cracked and perished lower suspension arm attachment brackets on both front corners. Although the tester judged structural strength was not seriously reduced at that time, perished mounting points on a nine-year-old vehicle warrant close inspection now, particularly if the car has spent long periods stationary. Rubber bushes and attachment points deteriorate with age as well as mileage, and a static vehicle can develop dry rot in suspension components that regular use might have kept supple. Have a garage put the car on a lift and check both front lower arms, subframe mounting points, and the condition of all suspension bushes for cracking or movement. Tyre condition has been a recurring theme. The 2024 advisory noted a perishing nearside rear tyre, and the March 2025 failure recorded a structural tear on the same tyre alongside cracking on the offside rear. Both were rectified before the subsequent pass, but the pattern suggests the vehicle may have sat on aged rubber. Inspect all four tyres for sidewall cracking, date codes, and uneven wear, paying attention to whether the current set is recent. Subaru's symmetrical all-wheel-drive system is sensitive to tyre diameter mismatches, so any replacement should be done as a full set or with closely matched rolling diameters to avoid drivetrain stress.
