Average for cars of the same age and mileage
Top failures
Brake pads worn below 1.5mm 1.67%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Wiper blade not clearing windscreen 1.51%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre cut reaching ply or cords 1.3%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp aim set too high 0.63%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre tread below 1.6mm 0.63%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too low 0.57%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Common advisories
Brake pads wearing thin (6.36%) · Tyre worn close to legal limit (5.73%) · Brake disc pitted or scored (4.53%) · Tyre slightly damaged or cracking (3.34%) · Child seat limits belt inspection (1.88%) · Nail in tyre, monitor (1.56%)
