MG GS 2016: MOT failure rate for its age

18.8% of 3,402 MOT tests of the MG GS first registered in 2016 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 95.6 (95% CI 88.2–103.1; 100 = normal for this model at that age): the 2016 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.

How does the 2016 MG GS fail at each age?

Cars built in 2016 were tested at ages 3 to 8 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.

What fails most on the 2016 MG GS?

The most common failure group on cars built in 2016 is lamps, reflectors and electrical equipment: 8.6 items per 100 first tests, against 6.8 across all build years of the MG GS. These counts are not age-adjusted: cars built in 2016 were tested at ages 3 to 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.
