Subaru Legacy 2001: MOT failure rate for its age

46.5% of 1,004 MOT tests of the Subaru Legacy first registered in 2001 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 108.3 (95% CI 98.5–118.2; 100 = normal for this model at that age): the 2001 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 does the 2001 Subaru Legacy fail at each age?

Cars built in 2001 were tested at ages 18 to 22 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 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.
