2015 Subaru Outback 2.0L Diesel · CE15 AOS

The 2015 Subaru Outback presents a stable and improving maintenance trend, culminating in a fully clean pass at 100,171 miles on 12 June 2025 with zero defects. The most recent test confirms the vehicle was presented in solid mechanical health, with no outstanding advisories or failures. This is a positive signal, particularly given that the preceding test in June 2024 at 91,360 miles had failed on multiple suspension defects. The pattern suggests a previous owner addressed those issues promptly and thoroughly, returning the car for a retest on the same day and passing cleanly. Two consecutive clean passes since then indicate the repairs have held and no new faults have emerged. The mileage accumulation is consistent and typical for an 11-year-old vehicle, averaging roughly 9,100 miles per year. The record shows steady annual increments: 72,132 miles in June 2022, 80,742 in June 2023, 91,360 in June 2024, and 100,171 in June 2025. There are no alarming gaps or sudden jumps in the odometer that would suggest long periods of disuse or tampering. The annual MOT pattern itself is disciplined, with tests booked close to the same date each year, which reflects a conscientious approach to upkeep. A buyer should still inspect the front and rear suspension with care. The June 2024 failure flagged excessively worn anti-roll bar D bushes on both rear sides and a worn nearside front lower suspension arm ball joint. While these were rectified for the retest, suspension wear on Subarus of this age and mileage is common, particularly if the vehicle has seen rough roads or light off-road use. Check for uneven tyre wear, clunking over bumps, and any play in the steering linkage, especially given the advisory for slight play in the nearside front inner steering ball joint noted back in June 2022 at 72,132 miles. That advisory did not reappear in later tests, but it is worth verifying the condition of the inner rack ends and track rod ends in person. The cracked nearside rear light casing flagged in 2022 was minor and likely replaced, but inspect the light unit for water ingress or poor repair. With 100,171 miles on the clock, also examine the condition of the brake discs and pads, the exhaust system for corrosion, and the underside for any signs of structural rust, particularly around the rear subframe and sills, which are known weak points on this generation Outback. The clean recent MOT is encouraging, but a physical inspection of these areas remains essential before purchase.
