Tesla Model X 2019: MOT failure rate for its age

16.7% of 3,402 MOT tests of the Tesla Model X first registered in 2019 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 111.4 (95% CI 102.3–120.6; 100 = normal for this model at that age): the 2019 Tesla Model X fails more often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.

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.
