Early warnings: advisories and minor defects at 7 years

Advisories and minor defects are recorded, but the car still passes. Across all cars, a part with an advisory or minor defect failed at the next MOT 5.5 times in 100 (n=88,666,940 pairs of consecutive MOTs), against 0.3 times in 100 when the same part had none (n=12,936,860,350).

Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing

On the Fiat 500X, testers most often record side/position light not working; tyre tread below 1.6 mm; track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt. Look at these first, then the areas below.

Lights and electrics

With someone outside, try every light: dipped and main beam, indicators, brake lights, fog lights and number plate lamps.
Check that the warning lights come on with the ignition and go out once the engine runs.
Look for misted, cracked or yellowed headlamp lenses.

Tyres

Check the tread across the full width of all four tyres, and the spare if there is one.
Look for cuts, bulges and cracking in the sidewalls.
Wear on one edge only can point to worn suspension or the tracking being out.

Steering

The steering should feel tight with no clunks when you turn from lock to lock.
On a straight road the car should hold its line without constant correction.
Look for split rubber gaiters on the steering rack and track rod ends.

Ask for the car's MOT history and service record: advisories that repeat from one year to the next show what has been left. GOV.UK MOT history.

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
