80.3% of Toyota Yaris tests and 70.4% of Vauxhall Corsa tests passed, including defects fixed during the test. This is a different outcome from passing at the first attempt.
What explains the difference?
The clearest difference is suspension: against its own class and age, the Toyota Yaris runs −4.4 items per 100 tests and the Vauxhall Corsa +4.5, so the Toyota Yaris has 8.9 fewer per 100 tests (95% interval 8.8 to 8.9).
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?

Recalls, other countries and running costs, side by side
DVSA lists 99 recall campaigns matched to the Toyota Yaris and 58 to the Vauxhall Corsa; 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.
