2017 Mitsubishi ASX 1.6L Petrol · AE67 VKW

The Mitsubishi ASX presents a worsening mechanical trend despite passing its most recent MOT on 2025-09-23 at 23,575 miles. For three consecutive years between 2021 and 2023, the vehicle passed without any defects recorded. However, the 2024 test at 21,794 miles introduced an advisory for an offside rear shock absorber with a light misting of oil, indicating the onset of a seal failure. This year's pass at 23,575 miles escalated the concern, with the tester flagging corrosion on both nearside and offside rear coil springs. Surface rust on coil springs can compromise structural integrity and lead to premature snapping, especially if the vehicle suffers from condensation cycling due to light use rather than regular heat cycling. The recorded mileage of 23,575 miles across nine years equates to a low annual average of roughly 2,619 miles. The MOT records show a steady, gradual accumulation, moving from 16,192 miles in September 2021 to 23,575 miles in September 2025. There are no sudden mileage spikes or significant gaps in the testing schedule, suggesting consistent, light usage rather than long periods of total inactivity. This low-mileage pattern typically preserves consumable wear items like brake discs and tyres, but it allows moisture to settle on underbody components, potentially contributing to the corrosion now appearing on the rear suspension. A physical inspection must focus heavily on the rear suspension and underbody condition. The tester flagged corrosion on both rear coil springs in the September 2025 test, a serious structural risk that requires close visual examination for pitting or scaling. The offside rear shock absorber noted as having a light oil misting in September 2024 at 21,794 miles demands scrutiny to determine if the leak has worsened into significant fluid loss, which would compromise damping. Buyers should also inspect the condition of the brake discs and calipers, as low-mileage vehicles often suffer from surface rust buildup on braking components that can lead to binding or uneven wear. Finally, check the exhaust system and underbody for accelerated corrosion, as the light use pattern may have allowed moisture to attack protective coatings.
