Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.32%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Windscreen washer fluid insufficient 0.62%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre tread below 1.6mm 0.62%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 0.53%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Headlamp aim set too low 0.35%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre bulge from structural failure 0.18%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Common advisories
Tyre worn close to legal limit (5.03%) · Brake pads wearing thin (3.09%) · Track rod ball joint slight play (0.88%) · Tyre worn close to legal limit (0.79%) · Nail in tyre, monitor (0.71%) · Child seat limits belt inspection (0.62%)
