Top failures
Wiper blade not clearing windscreen 2.16%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Parking brake efficiency below minimum 1.42%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre ply or cords exposed 1.4%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.22%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Parking brake inoperative on one side 1.06%
The parking brake does not work on one side, so the car may not hold on a slope and needs repair.
Parking brake efficiency under half required 0.8%
The parking brake is well below required strength and is unlikely to hold the car on a slope.
Common advisories
Tyre worn close to legal limit (8.89%) · Tyre slightly damaged or cracking (4.14%) · Brake disc pitted or scored (2.88%) · Brake pads wearing thin (2.42%) · Tyre worn close to legal limit (1.35%) · Nail in tyre, monitor (1.34%)
