Top failures
Coil spring fractured or broken 2.16%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre cut reaching ply or cords 1.37%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Side repeater not working 1.18%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Tyre bulge from structural failure 1.08%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Tyre ply or cords exposed 0.98%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Direction indicator wrong colour 0.88%
An indicator showing the wrong colour may confuse other drivers, so the lens or bulb should be replaced.
Common advisories
Tyre worn close to legal limit (7.75%) · Tyre slightly damaged or cracking (5.29%) · Brake pipes corroded and greasy (4.51%) · Brake disc pitted or scored (3.92%) · Brake pads wearing thin (2.25%) · Indicator lens slightly discoloured (2.25%)
