Kia Rio 2005: MOT failure rate for its age

50.6% of 6,028 MOT tests of the Kia Rio first registered in 2005 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 102.6 (95% CI 98.9–106.2; 100 = normal for this model at that age): the 2005 build year is no different from other years of the same model at the same age.

How to cite this page

MOT Risk Index (2026). Kia Rio 2005 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/2005/

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.
