Suzuki Alto 2011: MOT failure rate for its age
31.6% of 28,739 MOT tests of the Suzuki Alto 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 99.2 (95% CI 97.2–101.3; 100 = normal for this model at that age): the 2011 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 | 31.6 | % | all ages tested | 2019–2024 | 28739 |
| Index against this model at the same age (95% CI 97.2–101.3) | 99.2 | index | 100 = normal for this model at that age | 2019–2024 | 28739 |
| Rank among this model's 13 build years | 5 | of 13 | 1 = fails least for its age | 2019–2024 | 28739 |
| Tested in 2024 | 4497 | tests | median 64,449 miles | 2024 | 4497 |

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.
