Cars not tested again in that window are not included: 13.3% of those with a tyre advisory and 10.6% of the others.

Not enough 2021 Toyota Yaris cars with a brake or suspension advisory to show figures for this year alone.

Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.
