2021 Isuzu D-MAX DL20 Auto 1.9L Diesel · CT21 GUE

The Isuzu D-Max presents as roadworthy with a stable maintenance trend. The most recent test on 24 March 2026 at 118,568 miles returned a pass with no defects recorded, and the three preceding annual tests also passed cleanly. The lone failure on 3 April 2024 at 78,846 miles was anomalous, with the DVSA record showing no defects listed against the vehicle, suggesting an administrative or unrecorded-cause rejection rather than a mechanical fault. The mileage pattern reflects heavy use for a five-year-old pickup. From the 3 April 2024 failure at 78,846 miles, the vehicle covered 18,912 miles to the 3 April 2025 pass at 97,764 miles, then 20,804 miles to the March 2026 pass at 118,568 miles. That averages near 20,000 miles per year across the recorded period, well above typical private use and consistent with commercial or high-demand duty cycles. The MOT history is sparse, with only four entries, so no wear trends on consumables or mechanical assemblies can be inferred from advisories. A buyer should still commission a physical inspection of suspension bushes, coil springs, and brake discs given the high annual mileage and likely load-bearing work. The 2024 failure with no logged defects warrants confirmation that no outstanding structural or emissions issue was suppressed at retest. Check underneath for chassis corrosion and inspect the drivetrain for play, as the D-Max's age and mileage make these areas the most probable points of latent wear.
