Isuzu MOT pass rates
Isuzu’s first-time fail rate across 4 models was 26.2%, worse than the national 22.6%. The spread between models below is the interesting part.
| Model | Tests | Pass rate | Fail rate | Median miles |
|---|---|---|---|---|
| D-Max | 34,620 | 76% | 24% | 75,928 |
| Rodeo | 4,064 | 62.8% | 37.2% | 126,981 |

Fail rates are first attempts at class 4 normal tests in 2025, from DVSA’s anonymised data (retrieved 2026-09-12). Age mix drives a lot of the spread: a model sold mostly since 2020 will beat one whose survivors average 15 years old. Each model page shows the rate by age band.
