Tesla Model S 2017: MOT failure rate for its age
14.3% of 12,499 MOT tests of the Tesla Model S 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 97.5 (95% CI 93.0–102.1; 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 |
|---|---|---|---|---|---|
| Failed first time | 14.3 | % | all ages tested | 2019–2024 | 12499 |
| Index against this model at the same age (95% CI 93.0–102.1) | 97.5 | index | 100 = normal for this model at that age | 2019–2024 | 12499 |
| Rank among this model's 7 build years | 2 | of 7 | 1 = fails least for its age | 2019–2024 | 12499 |
| Tested in 2024 | 2520 | tests | median 70,981 miles | 2024 | 2520 |

How does the 2017 Tesla Model S 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 | 2,600 | 10.5 | 9.4–11.8 | 12.4 | 84.7 |
| 4 | 2,433 | 12 | 10.8–13.4 | 13.3 | 90.1 |
| 5 | 2,463 | 13.7 | 12.4–15.1 | 14.1 | 97.1 |
| 6 | 2,483 | 16.4 | 15–17.9 | 15.7 | 104.1 |
| 7 | 2,520 | 19.2 | 17.7–20.7 | 18 | 106.6 |

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.
