Top failures
Wiper blade not clearing windscreen 3.37%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Wheel bearing excessively rough 1.39%
A rough or noisy bearing is wearing out and may fail, so it should be inspected and replaced before it worsens.
Tyre tread below 1.6mm 0.97%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Windscreen washer fluid insufficient 0.88%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre cut reaching ply or cords 0.76%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Side repeater not working 0.74%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Common advisories
Tyre worn close to legal limit (11.06%) · Tyre slightly damaged or cracking (8.8%) · Brake disc pitted or scored (4.97%) · Brake pads wearing thin (2.39%) · Tyre worn close to legal limit (1.59%) · Suspension arm pin/bush showing wear (1.4%)
