Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 2.36%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Rear fog lamp not working 1.31%
A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.
Tyre cut reaching ply or cords 1.05%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Front fog lamp not working 0.79%
A non-working fog lamp is a MOT fail, so check the bulb, fuse and wiring before you buy.
Front fog lamp switch inoperative 0.7%
A dead front fog lamp switch stops you using the lamps in poor visibility, and it is a MOT fail.
Engine warning light inoperative or lit 0.7%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (7.01%) · Child seat limits belt inspection (2.45%) · Engine oil leak, not excessive (1.75%) · Brake pads wearing thin (1.58%) · Tyre has a shallow cut (1.23%) · Nail in tyre, monitor (1.14%)
