Suzuki Grand Vitara 2015: MOT failure rate for its age
13.3% of 256 MOT tests of the Suzuki Grand Vitara first registered in 2015 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 78.6 (95% CI 52.2–105.1; 100 = normal for this model at that age): the 2015 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 | 13.3 | % | all ages tested | 2019–2024 | 256 |
| Index against this model at the same age (95% CI 52.2–105.1) | 78.6 | index | 100 = normal for this model at that age | 2019–2024 | 256 |
| Rank among this model's 18 build years | 2 | of 18 | 1 = fails least for its age | 2019–2024 | 256 |

How does the 2015 Suzuki Grand Vitara fail at each age?
Cars built in 2015 were tested at ages 4 to 9 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.

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.
