Of the years with at least 100 tests, the 2020 model has the highest pass rate at 86% from 4,081 tests. The 2012 model has the lowest at 75%. The 11 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Reliability Trend

Newer Isuzu D-Maxs pass their MOT more often than older ones, by 6 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (2012) averages 112,031 miles, while the newest (2021) averages 43,288 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
