DS DS5 2015: MOT failure rate for its age
24.4% of 2,486 MOT tests of the DS DS5 first registered in 2015 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 102.3 (95% CI 94.2–110.5; 100 = normal for this model at that age): the 2015 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 | 24.4 | % | all ages tested | 2019–2024 | 2486 |
| Index against this model at the same age (95% CI 94.2–110.5) | 102.3 | index | 100 = normal for this model at that age | 2019–2024 | 2486 |
| Rank among this model's 4 build years | 4 | of 4 | 1 = fails least for its age | 2019–2024 | 2486 |

How does the 2015 DS DS5 fail at each age?
Cars built in 2015 were tested at ages 4 to 9 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) |
|---|---|---|---|---|---|
| 4 | 428 (rough estimate) | 19.9 | 16.4–23.9 | 21.4 | 92.6 |
| 5 | 400 (rough estimate) | 20.8 | 17.1–25 | 20.6 | 100.7 |
| 6 | 421 (rough estimate) | 24.2 | 20.4–28.5 | 22.4 | 108 |
| 7 | 415 (rough estimate) | 24.1 | 20.2–28.4 | 23.3 | 103.5 |
| 8 | 419 (rough estimate) | 27 | 22.9–31.4 | 25.8 | 104.5 |
| 9 | 403 (rough estimate) | 30.5 | 26.2–35.2 | 29.5 | 103.5 |

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.
