2015 Mitsubishi ASX 2.3L Diesel · Y1 BNG

The vehicle is currently roadworthy but the maintenance trend shows a clear worsening of structural surface corrosion. While it passed the most recent test in April 2026 at 39,103 miles, the tester flagged a significant volume of advisories that were not present in previous years. The transition from a clean record in 2024 to a comprehensive list of corrosion issues in 2026 indicates that environmental degradation is accelerating despite the low annual mileage accumulation. The mileage profile is exceptionally low for an eleven-year-old vehicle, averaging approximately 3,550 miles per year. There is a consistent pattern of usage, moving from 29,357 miles in April 2023 to 39,103 miles by April 2026. While this low mileage suggests less mechanical wear on the engine and drivetrain, the long periods of standing or light use associated with such figures often contribute to the rapid oxidation of exposed metal undercarriage components, as seen with the sub-frames and brake lines. A buyer must conduct a thorough underbody inspection to assess the depth of the reported rust. The 2026 record identifies corrosion on the front sub-frame, rear sub-frame, lower suspension arms, and all four coil springs. Although the tester noted these were not yet weakened, the presence of corrosion on all four brake hose ferrules and the rear fuel tank suggests the vehicle is prone to moisture retention. The grease-covered corroded brake pipes are particularly concerning as they may mask more significant metal loss from the visual inspector. Specific attention should also be paid to the braking system and tyres following the 2024 failure for worn front brake discs and the 2025 advisory for tyres reaching the legal limit. Given the recurring nature of structural advisories on the rear floor area and sub-frames, the buyer should verify that the integrity of the chassis remains intact and that the corrosion does not lead to failure in future MOT tests if the current trend continues.
