Isuzu D-Max MOT pass rates & common failures

Every completed first-attempt MOT on an Isuzu D-Max in Great Britain in 2025 — 37,263 tests. Figures cover every D-Max first-tested in 2025, all trims grouped. The D-Max is a van, tested in the car MOT class (class 4) to the same standard. How the D-Max ages, what it fails on, and what mileage is normal, computed directly from the official DVSA record of every test.

Better or worse than the average car?

The D-Max's pass rate minus the all-cars pass rate at each age, in percentage points. Bars above zero: the D-Max beats the average car of that age. Below zero: it trails.

What mileage is normal for a D-Max?

Mileage recorded at test by vehicle age, 2025. The line is the typical (median) D-Max; the shaded band holds the middle half. A car far outside the band, in either direction, is worth questions the recorded history can answer.

What fails at each age

The D-Max's failure mix by age band, 2025 — each band's top categories at their true share of that band's failure items; the pale remainder is everything else. How the mix shifts with age is the point of the chart.

How these figures are computed. Every number on this page is calculated by SortedCars from the DVSA anonymised MOT results dataset (every MOT test in Great Britain — 2025 for single-year figures; trend figures state their span, currently 2023–2025). Where a figure comes from a sample or uses banded values (mileage is banded to 2,500 miles), the page says so beside the figure. Test class 4 only, first tests only — retests are excluded. Class 4 is the car MOT class and also covers car-derived vans, pickups and motorhomes tested to the same standard; where this page says "cars" it means class 4. Pass rate = passes ÷ (passes + failures + pass-after-rectification): a vehicle that failed and was fixed during the visit counts as a fail. Pass rates describe fleets, not individual machines: they reflect how cars were driven, maintained and used as well as how they were built, and beyond recorded mileage none of that is in the data. A well-kept example of a model with a weak average can still pass; a neglected example of a strong one can still fail. No figure is shown for any group with fewer than 500 tests. Alias spellings of a make in the DVSA file are counted under one make name, and all trims and variants of a model are grouped under one model name, using SortedCars' grouping tables. “Dangerous” is DVSA's statutory defect category (in force since May 2018): a defect posing an immediate risk to road safety — driving the vehicle before repair is an offence. What these figures are for. These statistics are general information about groups of vehicles. They are not advice, a valuation or a recommendation to buy, avoid or price any particular vehicle, and no decision about one car should rest on them alone — check the car itself and its own records. We take care over the calculations, but we cannot guarantee they are complete, current or free of error, and we accept no liability for loss arising from reliance on them. This does not limit any liability that cannot lawfully be limited — see our Terms & Conditions. If you believe any figure on this page is inaccurate, contact us.
