After defects were fixed at the test centre
79.2% of Honda Jazz tests and 80.3% of Toyota Yaris tests passed, including defects fixed during the test. This is a different outcome from passing at the first attempt.
Raw pass rates point the other way because the fleets differ in age.
What explains the difference?
The clearest difference is lamps, reflectors and electrical equipment: against its own class and age, the Honda Jazz runs −3.8 items per 100 tests and the Toyota Yaris +1.1, so the Honda Jazz has 4.8 fewer per 100 tests (95% interval 4.7 to 4.9).
Each model is compared with its own class and age; the fleets can differ in mileage and use.

At what age does one of them fail more?
The Honda Jazz fails less at 17 of 17 ages where both are tested, and the gap points the same way at every age where it is clear. Across the 4 yearly tests from age 4 to 7, the gaps add up to 21.3 extra failed tests per 100 for the Toyota Yaris (a sum of yearly rates, not the chance of one car failing).

Where do their MOT failures diverge?
The clearest difference is lamps, reflectors and electrical equipment: against its own class and age, the Honda Jazz runs −3.8 items per 100 tests and the Toyota Yaris +1.1, so the Honda Jazz has 4.8 fewer per 100 tests (95% interval 4.7 to 4.9).

Recalls, other countries and running costs, side by side
DVSA lists 31 recall campaigns matched to the Honda Jazz and 99 to the Toyota Yaris; more campaigns do not by themselves mean a less reliable car. Abroad, compare each model with that country's own average, because pass rates do not carry across rulebooks. Repair bills are catalogue estimates, not quotes.
