Toyota GT86 2018: MOT failure rate for its age
9.4% of 1,859 MOT tests of the Toyota GT86 first registered in 2018 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 83.0–112.0; 100 = normal for this model at that age): the 2018 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 | 9.4 | % | all ages tested | 2019–2024 | 1859 |
| Index against this model at the same age (95% CI 83.0–112.0) | 97.5 | index | 100 = normal for this model at that age | 2019–2024 | 1859 |
| Rank among this model's 9 build years | 5 | of 9 | 1 = fails least for its age | 2019–2024 | 1859 |
| Tested in 2024 | 450 | tests | median 33,677 miles | 2024 | 450 |

How does the 2018 Toyota GT86 fail at each age?
Cars built in 2018 were tested at ages 3 to 6 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 | 473 (rough estimate) | 7.2 | 5.2–9.9 | 6.1 | 117.7 |
| 4 | 473 (rough estimate) | 8.2 | 6.1–11.1 | 8.9 | 93 |
| 5 | 463 (rough estimate) | 12.1 | 9.4–15.4 | 11.9 | 102 |
| 6 | 450 (rough estimate) | 10 | 7.6–13.1 | 11.7 | 85.3 |

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.
