BMW X4 2020: MOT failure rate for its age
11.9% of 3,848 MOT tests of the BMW X4 first registered in 2020 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 107.7 (95% CI 97.8–117.6; 100 = normal for this model at that age): the 2020 build year is no different from other years of the same model at the same age. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 11.9 | % | all ages tested | 2019–2024 | 3848 |
| Index against this model at the same age (95% CI 97.8–117.6) | 107.7 | index | 100 = normal for this model at that age | 2019–2024 | 3848 |
| Rank among this model's 7 build years | 6 | of 7 | 1 = fails least for its age | 2019–2024 | 3848 |
| Tested in 2024 | 1903 | tests | median 33,639 miles | 2024 | 1903 |

How does the 2020 BMW X4 fail at each age?
Cars built in 2020 were tested at ages 3 to 4 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 | 1,945 | 12.8 | 11.3–14.3 | 10.6 | 120.7 |
| 4 | 1,903 | 11 | 9.7–12.5 | 11.5 | 95.6 |

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.
