2012 Chevrolet Aveo 1.2L Diesel · CK12 FKA

The most recent MOT on 2026-05-21 recorded a pass with a note of rear sub-frame corrosion, described as "not seriously weakened" under 5.3.3 (b) (i). This aligns with a long-standing pattern of sub-frame corrosion observed since 2023, though the 2025-05-21 MOT included a failure due to a fractured offside front coil spring, pitted front brake discs, and excessive exhaust emissions. The 2025-06-02 MOT noted similar corrosion in both front and rear sub-frames, with a "strong advise" for the rear sub-frame. The recurring issue of sub-frame corrosion suggests a persistent vulnerability to rust, likely exacerbated by environmental factors or lack of use. While the 2026 MOT passed, the history shows that corrosion has not been resolved, and the 2025 failure included additional critical faults like a fractured coil spring and emissions超标. These indicate potential structural or mechanical degradation that may require closer scrutiny. The vehicle’s mileage of 52,412 miles over 14 years equates to roughly 3,744 miles annually, which is low for its age. This could imply periods of inactivity, increasing the risk of rust and component stiffness, or lighter use with less wear on moving parts. However, the presence of multiple corrosion issues and a fractured coil spring suggests that low mileage alone does not guarantee mechanical integrity. The trend shows some improvement since the 2025 failure, with subsequent MOTs passing, but the persistence of sub-frame corrosion and brake disc wear indicates unresolved underlying issues.
