MG GS 2019: MOT failure rate for its age
18.9% of 1,148 MOT tests of the MG GS first registered in 2019 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 134.3 (95% CI 116.4–152.2; 100 = normal for this model at that age): the 2019 MG GS fails more often than other build 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 | 18.9 | % | all ages tested | 2019–2024 | 1148 |
| Index against this model at the same age (95% CI 116.4–152.2) | 134.3 | index | 100 = normal for this model at that age | 2019–2024 | 1148 |
| Rank among this model's 4 build years | 4 | of 4 | 1 = fails least for its age | 2019–2024 | 1148 |
| Tested in 2024 | 384 | tests | median 35,799 miles | 2024 | 384 |

How does the 2019 MG GS fail at each age?
Cars built in 2019 were tested at ages 3 to 5 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 | 388 (rough estimate) | 12.6 | 9.7–16.3 | 10.4 | 121.9 |
| 4 | 376 (rough estimate) | 17.8 | 14.3–22 | 12.9 | 138.1 |
| 5 | 384 (rough estimate) | 26.3 | 22.1–30.9 | 19 | 138.6 |

What fails most on the 2019 MG GS?
The most common failure group on cars built in 2019 is brakes: 10.2 items per 100 first tests, against 7.6 across all build years of the MG GS. These counts are not age-adjusted: cars built in 2019 were tested at ages 3 to 5.

|---|---|---|---|
| Brakes | 10.2 | 7.6 | 119 |

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.
