Not enough 2018 Vauxhall Astra cars with a suspension advisory to show a figure 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.
