What stands out

Suspension fails show up on 2.6 of every 100 MOTs of a DS DS7 at 4 years old (n=3,638), against 0.9 for all cars of that age (n=8,699,937).

The fail item testers record most often at 4 years: tyre tread below 1.6 mm, on 3.4 per 100 MOTs (all cars 1.4).
The most common advisory or minor defect: tread depth: worn close to legal limit/worn on edge, on 15.9 per 100 MOTs.

Problems by part at 4 years

Early warnings: advisories and minor defects at 4 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.

How problems change with age

Fails per 100 MOTs in the three most common areas at 4 years. Ages with fewer than 1,000 tests are not shown.
Age	Tests (n)	Tyres	Lights and electrics	Brakes
3 years	3,349	4.6	3.0	2.2
4 years	3,638	5.2	3.4	2.7
5 years	3,033	5.4	4.8	3.7
6 years	2,433	5.6	4.2	4.5

Mileage

At 4 years, DS DS7 cars showing under 30,000 miles failed 12.4% of MOTs (n=1,509); the band that failed most, 30,000 to 60,000 miles, failed 15.7% (n=1,876). For pass and fail rates by age, see MOT fail rates by model.

What to check on a viewing

On the DS DS7, testers most often record tyre tread below 1.6 mm; brake pads under 1.5 mm; suspension arm bush worn. Look at these first, then the areas below.

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.

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.

Brakes

On the test drive the car should stop in a straight line without pulling, juddering or grinding.
Look at the discs through the wheels for a deep lip, heavy rust or scoring.
Check that the handbrake or electronic parking brake holds the car on a slope.
Ask when the pads, discs and brake fluid were last changed, and for the receipts.

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.
