Top failures
Wiper blade not clearing windscreen 0.86%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp aim set too high 0.68%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre cut reaching ply or cords 0.49%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Seat belt retractor defective 0.43%
A defective retractor may not lock or spool properly, so the belt may not restrain you in a crash.
Tyre tread below 1.6mm 0.31%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 0.25%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (6.22%) · Tyre slightly damaged or cracking (3.02%) · Nail in tyre, monitor (1.23%) · Tyre worn close to legal limit (1.17%) · Child seat limits belt inspection (1.17%) · Tyre has a shallow cut (0.92%)
