Expert verdict
Suspension: 1.4× the national share
Suspension accounts for 29.3% of everything recorded on the 2018 Isuzu D-Max, against 21.0% nationally — 8.3 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- Falls short of its own age and mileage. Like-for-like, cars this age and mileage expect about 87.9%; this one manages 82.6% — 5.3 points below. Age is a fair excuse; this is not age.

Where the Isuzu D-Max is most common
Across all D-Max model years on record (2012–2022): 43,205 Isuzu D-Max cars tested in a recordable postcode area, across 107,665 tests. Exeter (EX) has the most, with 1,241 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Isuzu D-Max cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2018 D-Max
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2018 D-Max
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the shock absorbers 3.8% of tests
“shock absorbers has an excessively worn bush”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
-
Check the lights 3.5% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the windscreen 3.3% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

Across the 10 items that are recorded most often on this model, the average repair comes to £25–£69 — and 49% of those repairs are parts that cost under £30.
