Tesla Model S 2014: MOT failure rate for its age
20.5% of 3,684 MOT tests of the Tesla Model S first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 100.0 (95% CI 92.9–107.1; 100 = normal for this model at that age): the 2014 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 | 20.5 | % | all ages tested | 2019–2024 | 3684 |
| Index against this model at the same age (95% CI 92.9–107.1) | 100.0 | index | 100 = normal for this model at that age | 2019–2024 | 3684 |
| Rank among this model's 7 build years | 4 | of 7 | 1 = fails least for its age | 2019–2024 | 3684 |
| Tested in 2024 | 605 | tests | median 102,481 miles | 2024 | 605 |

How does the 2014 Tesla Model S fail at each age?
Cars built in 2014 were tested at ages 5 to 10 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) |
|---|---|---|---|---|---|
| 5 | 658 | 13.5 | 11.1–16.4 | 15.9 | 85.1 |
| 6 | 589 | 17 | 14.2–20.2 | 16.3 | 104 |
| 7 | 605 | 15.7 | 13–18.8 | 18.6 | 84.5 |
| 8 | 615 | 22.8 | 19.6–26.2 | 20.8 | 109.4 |
| 9 | 612 | 26 | 22.7–29.6 | 24.1 | 107.8 |
| 10 | 605 | 28.4 | 25–32.2 | 27.5 | 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.
