Top failures
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.
Tyre cut reaching ply or cords 0.45%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Windscreen washer fluid insufficient 0.32%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Headlamp aim set too high 0.26%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Coil spring fractured or broken 0.26%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre bulge from structural failure 0.26%
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 (3.88%) · Tyre slightly damaged or cracking (3.35%) · Brake disc pitted or scored (1.78%) · Nail in tyre, monitor (1.4%) · Brake pipes corroded and greasy (1.2%) · Brake pads wearing thin (1.07%)
