DS Ds3 (2021)
2021 DS Ds3
CarHunch analysed 682 real MOT records for the 2021 DS Ds3. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 DS DS3 is a strong performer with an 88.9% first-time pass rate that sits well above the UK average of 80%, suggesting above-average reliability for the model year. Dangerous defects are rare at 6.3%, so structural or safety concerns shouldn't trouble most buyers, and there's no meaningful difference between petrol (89.1%) and diesel (88.2%) variants.
These cars are running low mileage for their age—averaging 27,043 miles—which explains the healthy pass rate and suggests many are still lightly used. The average of 0.37 failures and 2.0 advisories per test indicates the typical issue is routine wear rather than serious mechanical trouble, so if you're shopping used, get a pre-purchase inspection focused on suspension and minor wear items rather than engine reliability.
What to check before buying a 2021 DS Ds3
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
