Should I check the MOT history before buying a 2021 Isuzu D Max Dl40 Auto?

Do I need an HPI check when buying a 2021 Isuzu D Max Dl40 Auto?

Moderate sample. 438 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Isuzu D-Max DL40 Auto is a reliable pickup with an 89.2% first-time pass rate, significantly ahead of the UK average of 80%, and dangerous defects are rare at just 6.2% of vehicles. This is a straightforward performer that buyers can approach with confidence.

At nearly 48,000 miles on average, these vehicles are running typical mileage for their age, and the low failure rate of 0.29 per vehicle suggests the mechanicals are holding up well. With 1.7 advisories per vehicle on record, expect minor wear items like suspension bushes or brake pad warnings rather than serious issues—but given the model's work-truck reputation, get a pre-purchase inspection focused on chassis and undercarriage condition.

The 2021 Isuzu D Max Dl40 Auto passes its MOT first time more often than most UK vehicles (90.5% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 90.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 438 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
