Top failures
Coil spring fractured or broken 5.38%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Dipped beam headlamp not working 4.1%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Main beam headlamp not working 2.48%
A failed main beam reduces night-time visibility on unlit roads, so the headlamp should be repaired promptly.
Tyre pressure monitoring system faulty 2.22%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Tyre tread below 1.6mm 1.97%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake discs significantly worn 1.54%
Heavily worn discs reduce braking performance and wear pads faster, so a replacement will soon be needed.
Common advisories
Brake disc pitted or scored (19.32%) · Tyre worn close to legal limit (14.19%) · Tyre slightly damaged or cracking (7.44%) · Brake pads wearing thin (5.56%) · Nail in tyre, monitor (2.31%) · Service brake slightly binding (2.14%)
