2020 Isuzu D-MAX 1.9L Diesel · VE20 VSO

The 2020 ISUZU D-MAX’s latest MOT test on 2026-06-11 resulted in a passing grade, but the vehicle’s maintenance history reveals a concerning pattern. While the preceding three MOTs from 2023 to 2026 were clean, the 2023 MOT on 2023-05-30 marked the first failure, with a major defect in the nearside rear shock absorber’s bush and an advisory for the offside rear shock absorber’s slightly worn bush. These defects are indicative of progressive wear in the suspension system, which, if left unaddressed, could lead to increased handling instability, premature component failure, and potential roadworthiness risks such as uneven tyre wear or suspension binding. The fact that these issues were not rectified before the 2024 MOT suggests either inadequate maintenance or a lack of urgency in addressing the problem, which is particularly alarming given the vehicle’s age and the wear already evident in the suspension bushes. The recorded mileage of 56,868 miles for a 2020 D-MAX represents a reasonable annual usage rate of approximately 9,478 miles per year, which aligns with typical driving patterns for this model. However, the mileage data alone does not fully explain the suspension defects, as lower mileage could theoretically imply less wear if the vehicle was driven more sparingly or stood for extended periods. Conversely, higher mileage might suggest more aggressive use, accelerating component fatigue—particularly in suspension, brakes, and drivetrain components. The absence of significant mileage spikes or long periods of inactivity does not mitigate the risk posed by the known bush wear, as wear progression in suspension bushes is often cumulative and influenced by both mileage and driving conditions, such as rough roads or excessive body roll. Given the suspension defects recorded in the MOT history, the prospective buyer should prioritise a thorough inspection of the rear suspension system. The nearside rear shock absorber’s bush failure is critical; this component is essential for damping vertical motion and maintaining vehicle stability. Symptoms to watch for during a test drive include excessive clunking or rattling from the rear axle area when driving over bumps, reduced ride comfort, or a noticeable sagging or uneven ride height on the nearside. The offside rear shock absorber’s slightly worn bush should also be examined closely, as it may develop similar issues if left unattended. Listen for any unusual noises from the rear suspension when accelerating, braking, or cornering, and check for uneven tyre wear patterns, which could indicate misalignment or suspension misalignment caused by worn bushes. Immediate replacement of the failed nearside bush and the offside bush is strongly advised to prevent further deterioration, potential handling issues, and the risk of a future MOT failure due to suspension defects. Beyond the suspension, the buyer should conduct a comprehensive physical inspection of the vehicle to address potential age-related wear and potential hidden issues. Given the vehicle’s age and the moderate mileage, focus on the rear suspension components, including the struts, coil springs, and control arms, for signs of corrosion or excessive play. Inspect the rear wheel bearings for excessive play or grinding noises, which could indicate bearing failure. Check the brake system for signs of corrosion on the discs or binding calipers, particularly if the vehicle has been stationary for prolonged periods. The brake fluid should be checked for contamination or degradation, as standing brake fluid can absorb moisture and lead to brake system failure. Additionally, verify the condition of the tyres, ensuring there is adequate tread depth and checking for sidewall cracking or perishing, which can compromise tyre integrity. Lastly, assess the 12V battery and associated electrical systems, as older vehicles may experience reduced battery life or starter motor issues due to age-related wear. A full service history check should also be requested to confirm that scheduled maintenance, such as oil changes, timing belt replacement, and fluid servicing, has been conducted according to the manufacturer’s recommendations.
