Top failures
Tyre cut reaching ply or cords 1.98%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Wiper blade not clearing windscreen 1.68%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 0.93%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 0.87%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Side repeater not working 0.42%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Headlamp aim set too high 0.39%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (9.47%) · Tyre slightly damaged or cracking (4.03%) · Brake pads wearing thin (3.19%) · Child seat limits belt inspection (2.69%) · Nail in tyre, monitor (1.81%) · Brake disc pitted or scored (1.72%)
