Unadjusted, not ranked
Other Isuzu models with MOT data
These models have at least 500 recorded tests, but their tested examples do not span enough ages and mileages to rank fairly. Their failure and advisory patterns are still drawn from real tests.

| Isuzu Rodeo | 55.1% | 4,178 |
| Isuzu Trooper | 62.4% | 1,897 |

Common questions
- What is the MOT pass rate for Isuzu?
- Across 44,207 recorded MOT tests, 68.5% of Isuzu tests ended in a pass, against a national average of 72.3%. Adjusted for the age and mileage of the cars tested, the figure is 72.3%. A make-level figure blends very different cars, so the individual model pages are the more useful comparison.
- Which Isuzu is the most reliable on MOT evidence?
- Of the Isuzu models with enough data to compare fairly, the D-Max has the highest age-and-mileage-adjusted pass rate at 72.3%, ranking 142 of 262 models nationally. This reflects how often cars meet the MOT standard, not how often they break down.
- What do Isuzu cars most often fail their MOT on?
- The most commonly recorded failure item across Isuzu tests is "A shock absorber bush excessively worn", appearing in 19.1% of failed tests. One failed test can list several items, so these shares do not add up to 100%.
- Why do some Isuzu models not have a pass rate ranking?
- A model is only ranked when its tested examples cover a wide enough spread of ages and mileages for a fair comparison. 1 of the 4 Isuzu models here qualify. For the rest we publish the unadjusted rate and the failure patterns, but not a rank, because comparing unadjusted rates mostly sorts cars by how new they are.
How to read these figures
Why the adjusted rate is the fair one
An unadjusted pass rate is strongly driven by the age and mileage of the cars being tested, not by how well they were built. A model bought mainly as a lightly used second car will look better than an identical car sold to high-mileage drivers. Adjusting for age and mileage compares each model against cars that have lived a similar life.
