LTI TX4 2016: MOT failure rate for its age
32.1% of 9,370 MOT tests of the LTI TX4 first registered in 2016 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 91.7 (95% CI 88.4–94.9; 100 = normal for this model at that age): the 2016 LTI TX4 fails less often than other build years of the same model at the same age.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 32.1 | % | all ages tested | 2019–2024 | 9370 |
| Index against this model at the same age (95% CI 88.4–94.9) | 91.7 | index | 100 = normal for this model at that age | 2019–2024 | 9370 |
| Rank among this model's 12 build years | 1 | of 12 | 1 = fails least for its age | 2019–2024 | 9370 |
| Tested in 2024 | 1583 | tests | median 162,066 miles | 2024 | 1583 |

How does the 2016 LTI TX4 fail at each age?
Cars built in 2016 were tested at ages 3 to 8 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) |
|---|---|---|---|---|---|
| 3 | 1,716 | 32.2 | 30–34.4 | 33.6 | 95.8 |
| 4 | 1,235 | 29.8 | 27.3–32.4 | 32 | 93 |
| 5 | 1,559 | 33.1 | 30.8–35.5 | 35.7 | 92.7 |
| 6 | 1,622 | 33.8 | 31.6–36.2 | 35.1 | 96.6 |
| 7 | 1,655 | 30.1 | 27.9–32.3 | 35.6 | 84.4 |
| 8 | 1,583 | 33.4 | 31.1–35.8 | 37.9 | 88.3 |

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.
