Kia Rio 2017: MOT failure rate for its age
13.8% of 42,255 MOT tests of the Kia Rio 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 82.9 (95% CI 80.7–85.0; 100 = normal for this model at that age): the 2017 Kia Rio fails less often than other build years of the same model at the same age.

MOT Risk Index (2026). Kia Rio 2017 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/kia-rio/2017/
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.
