Lexus RC 2017: MOT failure rate for its age
11.5% of 2,293 MOT tests of the Lexus RC first registered in 2017 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 106.5 (95% CI 93.6–119.3; 100 = normal for this model at that age): the 2017 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 | 11.5 | % | all ages tested | 2019–2024 | 2293 |
| Index against this model at the same age (95% CI 93.6–119.3) | 106.5 | index | 100 = normal for this model at that age | 2019–2024 | 2293 |
| Rank among this model's 6 build years | 5 | of 6 | 1 = fails least for its age | 2019–2024 | 2293 |
| Tested in 2024 | 430 | tests | median 44,681 miles | 2024 | 430 |

How does the 2017 Lexus RC fail at each age?
Cars built in 2017 were tested at ages 3 to 7 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 | 551 | 7.6 | 5.7–10.1 | 8.2 | 93.5 |
| 4 | 436 (rough estimate) | 14 | 11–17.6 | 12.1 | 115.9 |
| 5 | 439 (rough estimate) | 12.5 | 9.8–16 | 10.6 | 118.7 |
| 6 | 437 (rough estimate) | 10.8 | 8.2–14 | 10.9 | 98.7 |
| 7 | 430 (rough estimate) | 13.5 | 10.6–17 | 12.9 | 104.5 |

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.
