Failure areas compared with all 2017 vehicles

Compared with all vehicles first used in 2017, failures are more common in lights and electrics (1.1×) and suspension (1.0×), and less common in tyres (0.7×) and brakes (0.7×). Other differences are within the margin of error.

Failed tests with a fault in each area, per 100 tests. The right-hand column shows how many times as often as all vehicles first used in 2017.

All vehicles first used in 2017: the 240 models in our data, 2,515,956 tests (97.6% of all 2,578,403 tests on vehicles first used in 2017). Areas with fewer than 50 failures in a model aren't published, so an area is only compared when that leaves the all-vehicles figure at most 10% short; otherwise it shows –.

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.
