2021 DS Ds 3 Crossback Ultra Prstge Ev — MOT failures & pass rate
Across 671 MOT tests, the 2021 DS Ds 3 Crossback Ultra Prstge Ev recorded an 88.2% pass rate. All cars of a similar age fail 8.6% of the time, so this is 3.1pp worse than the group it competes with. Failures cluster in visibility, suspension and tyres.
What the MOT record shows
No single area dominates — visibility (6.6%) and suspension (4.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and ball joint — wipers alone was recorded 55 times.
Tyres is the most common advisory, noted on 22.9% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 Ds 3 Crossback Ultra Prstge Ev
The failure pattern for this year is specific enough to inspect against: visibility accounted for 6.6% of tests. Start there.
- Visibility (6.6% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Suspension (4.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Tyres (3.4% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
