Should I check the MOT history before buying a 2018 DS Ds4?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2018 DS Ds4?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2018 DS Ds4?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Moderate sample. 374 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2018 DS DS4 passes its MOT slightly above the UK average at 83.2%, which is a solid result, but the 27% dangerous defect rate is a genuine concern—over a quarter of these cars have picked up a serious safety issue at some point. Both diesel and petrol versions perform similarly (83.9% and 82.3% respectively), so fuel type isn't a meaningful differentiator here.

At 37,500 miles average for a six-year-old car, these DS4s are running well below typical wear and tear, yet they still rack up 1.22 failures and 6.7 advisories per test on average—suggesting some underlying quality or maintenance issues beyond just age-related wear. Before buying, get a full pre-purchase inspection focusing on electrical and suspension components, as these tend to be repeat problem areas on French cars of this generation.

The 2018 DS Ds4 has a decent first-time pass rate (83.2%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 6.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 374 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
