Lexus GS 2014: MOT failure rate for its age
11.1% of 3,095 MOT tests of the Lexus GS first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 100.3 (95% CI 89.7–110.9; 100 = normal for this model at that age): the 2014 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 | 11.1 | % | all ages tested | 2019–2024 | 3095 |
| Index against this model at the same age (95% CI 89.7–110.9) | 100.3 | index | 100 = normal for this model at that age | 2019–2024 | 3095 |
| Rank among this model's 18 build years | 9 | of 18 | 1 = fails least for its age | 2019–2024 | 3095 |
| Tested in 2024 | 509 | tests | median 76,413 miles | 2024 | 509 |

How does the 2014 Lexus GS fail at each age?
Cars built in 2014 were tested at ages 5 to 10 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.
