Should I check the MOT history before buying a 2021 Isuzu D Max Dl20 Auto?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Isuzu D Max Dl20 Auto?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Isuzu D Max Dl20 Auto?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Based on MOT data from 152 vehicles, the 2021 Isuzu D Max Dl20 Auto has a first-time MOT pass rate of 83.4%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Isuzu D Max Dl20 Auto?

The 2021 Isuzu D-Max DL20 Auto passes its MOT on the first attempt 83.4% of the time, which is a solid 3.4 percentage points above the UK average—this pickup truck is proving more reliable than typical for its age. The 12.5% rate of dangerous defects is moderate and not a major red flag, though buyers should still factor in potential safety-critical repairs.

At 52,843 miles average, these vehicles are running a touch above typical mileage for their age, yet they're averaging just 0.51 failures per test, suggesting the extra miles haven't taken much of a toll. The real-world picture is one of minor niggles: advisories average 1.9 per vehicle, mostly low-cost wear items. When shopping, have a pre-purchase inspection focus on the suspension and braking components—the staples of pickup truck wear—to catch small issues before they compound.
