In 2025, 27,250 Isuzu D-Max cars had a regular MOT in Great Britain. 69% passed first time, compared with 77% for all cars of the same ages, which makes the D-Max worse than average. Most are commercial vans or pick-ups, which usually cover far higher mileages and harder work than private cars, so we leave them out of the car rankings.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 4 years old, 82% of D-Maxs passed first time (all cars that age: 87%). By 12 years, that figure is 59% (all cars: 66%). It trails the average car at most ages, most noticeably at 5 years (9 points behind).

What to check when buying a used D-Max
Based on where the D-Max fails more often than other cars, these are the checks worth making before you buy:
- Brakes: Look through the wheels for lipped or scored discs, check the handbrake holds on a slope, and feel for pulling or vibration under firm braking. Repair guide
- Body and structure: Get underneath with a torch: sills, jacking points, subframe mounts and floor pans. Structural rust is the failure that can make a car uneconomic to fix. Repair guide
- Suspension: Listen for knocks over speed bumps, look for leaking shock absorbers, and check the car sits level. Ask whether springs, bushes or drop links have been replaced. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
