DS 3 2015: MOT failure rate for its age
35.1% of 92,144 MOT tests of the DS 3 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 102.6 (95% CI 101.5–103.7; 100 = normal for this model at that age): close to other build years of the same model at the same age (within 5 points of normal).
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 35.1 | % | all ages tested | 2019–2024 | 92144 |
| Index against this model at the same age (95% CI 101.5–103.7) | 102.6 | index | 100 = normal for this model at that age | 2019–2024 | 92144 |
| Rank among this model's 11 build years | 7 | of 11 | 1 = fails least for its age | 2019–2024 | 92144 |

How does the 2015 DS 3 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 | 15,749 | 25.4 | 24.8–26.1 | 23.6 | 107.7 |
| 5 | 15,246 | 31 | 30.3–31.7 | 28.1 | 110.3 |
| 6 | 15,462 | 33.4 | 32.6–34.1 | 32.4 | 103 |

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.
