Suzuki Alto 2012: MOT failure rate for its age
29.9% of 29,025 MOT tests of the Suzuki Alto first registered in 2012 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 101.0 (95% CI 98.9–103.1; 100 = normal for this model at that age): the 2012 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 | 29.9 | % | all ages tested | 2019–2024 | 29025 |
| Index against this model at the same age (95% CI 98.9–103.1) | 101.0 | index | 100 = normal for this model at that age | 2019–2024 | 29025 |
| Rank among this model's 13 build years | 8 | of 13 | 1 = fails least for its age | 2019–2024 | 29025 |
| Tested in 2024 | 4588 | tests | median 59,276 miles | 2024 | 4588 |

How does the 2012 Suzuki Alto fail at each age?
Cars built in 2012 were tested at ages 7 to 12 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) |
|---|---|---|---|---|---|
| 7 | 5,105 | 25.3 | 24.2–26.6 | 26.6 | 95.4 |
| 8 | 4,851 | 27.6 | 26.3–28.9 | 26.7 | 103.5 |
| 9 | 4,870 | 28.7 | 27.4–30 | 28.8 | 99.8 |

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.
