Lexus RC 2020: MOT failure rate for its age

9.5% of 515 MOT tests of the Lexus RC first registered in 2020 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 97.3 (95% CI 70.0–124.5; 100 = normal for this model at that age): the 2020 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 to cite this page

MOT Risk Index (2026). Lexus RC 2020 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/lexus-rc/2020/

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.
