MINI Hatch 2018: MOT failure rate for its age

11.7% of 170,904 MOT tests of the MINI Hatch first registered in 2018 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 93.9 (95% CI 92.6–95.2; 100 = normal for this model at that age): the 2018 MINI Hatch fails less often than other build years of the same model at the same age.

How does the 2018 MINI Hatch fail at each age?

Cars built in 2018 were tested at ages 3 to 6 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 to cite this page

MOT Risk Index (2026). MINI Hatch 2018 MOT statistics (data release dvsa-2024-v2; full dataset motriskindex-families-2024-v5, DOI 10.5281/zenodo.22975051), updated 30 September 2026. motriskindex.co.uk/cars/mini-hatch/2018/

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.
