DS 3 2011: MOT failure rate for its age
49.0% of 60,013 MOT tests of the DS 3 first registered in 2011 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 103.8 (95% CI 102.6–104.9; 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 | 49.0 | % | all ages tested | 2019–2024 | 60013 |
| Index against this model at the same age (95% CI 102.6–104.9) | 103.8 | index | 100 = normal for this model at that age | 2019–2024 | 60013 |
| Rank among this model's 11 build years | 9 | of 11 | 1 = fails least for its age | 2019–2024 | 60013 |
| Tested in 2024 | 9053 | tests | median 90,191 miles | 2024 | 9053 |

How does the 2011 DS 3 fail at each age?
Cars built in 2011 were tested at ages 8 to 13 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) |
|---|---|---|---|---|---|
| 8 | 10,861 | 47.2 | 46.3–48.2 | 46.1 | 102.4 |
| 9 | 10,105 | 47.6 | 46.7–48.6 | 45.6 | 104.4 |
| 10 | 10,207 | 49.7 | 48.8–50.7 | 47.5 | 104.7 |
| 11 | 10,051 | 49.2 | 48.2–50.1 | 47.3 | 103.9 |

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.
