Isuzu D Max (2021)
2021 Isuzu D Max
CarHunch analysed 373 real MOT records for the 2021 Isuzu D Max. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Isuzu D-Max is beating the UK average with an 86.5% first-time pass rate versus 80%, which suggests solid build quality and owner care on these trucks. Only 6.7% have ever recorded a dangerous defect, so safety issues are well below concerning levels.
These D-Maxes average 47,698 miles at test time—reasonable for three-year-old work vehicles—and rack up just 0.38 failures per MOT, indicating mechanically sound trucks overall. Before buying, check the service history carefully, as the 1.8 average advisories per vehicle suggest routine wear on suspension and brakes is fairly common on this model; a pre-purchase inspection by a mechanic familiar with Isuzu pickups will catch any early signs of costly repairs.
What to check before buying a 2021 Isuzu D Max
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
