After defects were fixed at the test centre
83.9% of Nissan Leaf tests and 85.4% of Tesla Model 3 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 tyres: against its own class and age, the Nissan Leaf runs −3.3 items per 100 tests and the Tesla Model 3 +11.4, so the Nissan Leaf has 14.7 fewer per 100 tests (95% interval 14.4 to 15.0).
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 Nissan Leaf fails less at 3 of 3 ages where both are tested, and the gap points the same way at every age where it is clear. Across the 2 yearly tests from age 4 to 7, the gaps add up to 5.7 extra failed tests per 100 for the Tesla Model 3 (a sum of yearly rates, not the chance of one car failing).

Recalls, other countries and running costs, side by side
DVSA lists 6 recall campaigns matched to the Nissan Leaf and 11 to the Tesla Model 3; 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.
