Top failures
Tyre bulge from structural failure 6.14%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Wiper blade not clearing windscreen 2.05%
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 1.16%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre lump from structural separation 0.89%
A tyre lump means its structure has partly failed and it could burst, so replace it immediately.
Headlamp aim set too high 0.71%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre ply or cords exposed 0.71%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Brake disc pitted or scored (4%) · Tyre slightly damaged or cracking (3.83%) · Road wheel slightly distorted (3.47%) · Tyre worn close to legal limit (3.2%) · Brake pads wearing thin (2.58%) · Tyre showing slight damage (1.69%)
