Fiat 500L 2017: MOT failure rate for its age
23.7% of 4,597 MOT tests of the Fiat 500L first registered in 2017 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 101.4 (95% CI 95.4–107.4; 100 = normal for this model at that age): the 2017 build year is no different from other years of the same model at the same age.
| Measure | Value | Unit | Compared with | Years | Tests |

How does the 2017 Fiat 500L fail at each age?
Cars built in 2017 were tested at ages 3 to 7 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 | 1,033 | 15.4 | 13.3–17.7 | 18.4 | 83.5 |
| 4 | 890 | 20.7 | 18.1–23.5 | 21.2 | 97.5 |

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.
