2021 Isuzu D-MAX DL20 1.9L Diesel · ST21 EFD

Significant suspension failures define the mid-life record of this vehicle, specifically a fractured nearside rear leaf spring and worn shock absorber bushes across both the front and rear axles. These defects led to two failed tests in April and May 2024, though the vehicle subsequently passed its most recent inspections on 31 January 2025 and 13 February 2026 without any recorded defects. This indicates a period of structural suspension wear that was addressed prior to the more recent clean test outcomes. The recorded mileage of 46,861 miles over approximately five years represents an average annual accumulation of roughly 9,372 miles. This usage pattern is typical for a vehicle of this age and type, suggesting a standard rate of wear on the drivetrain, brake discs, and other consumable components. There are no significant gaps in the testing history that would suggest prolonged periods of inactivity. Given the history of fractured leaf springs and worn shock absorber bushes, a physical inspection should focus on the rear suspension assembly and the front lower shock mounts. During a test drive, listen for any knocks or clunks when traversing uneven surfaces or speed bumps, as these can indicate that replacement bushes are wearing prematurely or that the suspension is not settling correctly. Attention should also be paid to the windscreen wiper mechanism, which caused a failure in May 2024 due to ineffective clearing. Ensure the blades are currently sweeping the glass cleanly without streaking or juddering. Finally, verify the stability of the vehicle during cornering to ensure the previous leaf spring failure has been fully rectified with components that meet manufacturer specifications.
