Lexus GS 2011: MOT failure rate for its age
15.7% of 420 MOT tests of the Lexus GS 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 93.4 (95% CI 70.9–115.9; 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. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 15.7 | % | all ages tested | 2019–2024 | 420 |
| Index against this model at the same age (95% CI 70.9–115.9) | 93.4 | index | 100 = normal for this model at that age | 2019–2024 | 420 |
| Rank among this model's 18 build years | 6 | of 18 | 1 = fails least for its age | 2019–2024 | 420 |

How does the 2011 Lexus GS fail at each age?
Cars built in 2011 were tested at ages 8 to 13 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) |
|---|---|---|---|---|---|
| 8 | 76 (rough estimate) | 11.8 | 6.4–21 | 13.2 | 89.7 |
| 9 | 72 (rough estimate) | 15.3 | 8.8–25.3 | 12.1 | 125.8 |

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.
