Isuzu TF 2011: MOT failure rate for its age
41.7% of 6,097 MOT tests of the Isuzu TF first registered in 2011 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 99.6 (95% CI 95.8–103.5; 100 = normal for this model at that age): the 2011 build year is no different from other years of the same model at the same age.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 41.7 | % | all ages tested | 2019–2024 | 6097 |
| Index against this model at the same age (95% CI 95.8–103.5) | 99.6 | index | 100 = normal for this model at that age | 2019–2024 | 6097 |
| Rank among this model's 4 build years | 2 | of 4 | 1 = fails least for its age | 2019–2024 | 6097 |

How does the 2011 Isuzu TF fail at each age?
Cars built in 2011 were tested at ages 8 to 13 between 2019 and 2024. Each row compares their first-time failure share with what this model normally shows at that age, after allowing for the overall failure level of each test year.
| Age | Tests | Failed, % | 95% interval | Normal for this model at that age, % | Index (100 = normal) |
|---|---|---|---|---|---|
| 8 | 1,135 | 38.1 | 35.4–41 | 41.5 | 92 |
| 9 | 1,056 | 40.2 | 37.2–43.1 | 41.6 | 96.5 |

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
