2002 Subaru Forester 2.0L Petrol · BU52 PLX

A 24-year-old Subaru Forester with 176,196 miles presents a mechanical profile dominated by chronic corrosion and rear suspension wear, and the current MOT status confirms that structural deterioration is now an active concern. The most recent test on 5 February 2026 resulted in a failure with three major defects, including an inoperative engine management warning lamp (MIL), a windscreen crack encroaching on the driver's view, and a split offside front constant velocity joint boot allowing dirt contamination. These failures sit atop advisories from the same test noting corrosion on the nearside rear inner sill mounting area and general rear suspension component corrosion. Prior history reinforces this pattern: a 2021 test recorded an excessively corroded offside rear inner sill that significantly reduced structural strength, and 2023 brought a dangerous failure for inoperative rear stop lamps alongside deteriorated front lower ball joint dust covers. The cumulative picture points to a vehicle whose structural shell and rear suspension hardware are in measurable decline rather than early wear. Mileage accumulation across the recorded tests averages roughly 7,300 miles annually, which is broadly typical for a vehicle of this age, though the test cadence tells its own story. The earliest test on record dates to November 2020, meaning the Forester operated for approximately 18 years before appearing in this MOT dataset, and between November 2021 and November 2022 there is a near-continuous succession of tests suggesting the vehicle has been used fairly consistently in recent years. The risk profile this creates is straightforward: even at average annual mileage, a quarter-century-old vehicle carries elevated wear on all rotating and articulating components, and the gaps in the early life record mean there is no visibility into whether consumables such as the timing belt, clutch, or gearbox have been renewed at appropriate intervals. The 176,196-mile odometer reading should be treated as the starting point for a thorough service history audit, not as a reassurance of low wear. For a prospective buyer, the rear suspension and underbody corrosion issues warrant the closest physical inspection. The 2025 test recorded worn trailing arm and lateral rod pin or bush wear on both sides without excessive movement, and the 2026 test escalates this with corrosion at the inner sill mounting point for the nearside rear suspension component. On a test drive, listen for clonks or shuffling from the rear over speed humps and uneven tarmac, particularly during direction changes, and check whether the rear axle feels loose or whether there is any lateral shuffling under braking. With the vehicle raised or viewed from beneath, inspect the inner sills, rear subframe mounts, and trailing arm brackets for perforation rather than surface scale, paying particular attention to the offside rear sill which previously failed on excessive corrosion. Front lower ball joint dust covers were noted as deteriorated in 2022 and again in 2023, so check for any play in the front lower arms by rocking the wheels with the car lifted and examine the CV joint boots for fresh grease loss given the recent boot split failure. The drivetrain and braking items recorded also deserve targeted attention. The current engine MIL fault means the vehicle's on-board diagnostic system was either not illuminating the warning lamp or showing a stored malfunction, so before purchase the car should be scanned with an OBD-II reader to confirm whether there are active or historic fault codes relating to the engine, emissions, or lambda sensors, as unresolved MIL issues can mask catalytic converter or air-fuel ratio problems. The split offside front CV boot will require immediate replacement and the joint should be inspected for any clicking on full-lock turns at low speed. Brakes were flagged with both front pads wearing thin in late 2023, and given the mileage these will almost certainly need replacement; verify pedal feel is firm and that there is no pulling under braking, which could indicate a binding caliper. Finally, the windscreen damage recorded as a major failure must be repaired or replaced before the vehicle can be re-tested, and the rear stop lamp fault from 2023 should be checked by confirming all rear lighting functions correctly, as repeat electrical faults on a vehicle of this age can indicate broader wiring loom deterioration.
