2018 DS Ds5 — MOT failures & pass rate

665 MOT tests on the 2018 DS Ds5 are in this dataset, and 86.8% of them passed. That is effectively the same as large family cars of a similar age (12.3% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, visibility and brakes.

What the MOT record shows

No single area dominates — tyres (6.9%) and visibility (4.8%) 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 joints — wipers alone was recorded 36 times.

Condition tracks the odometer closely. Failures run at 11.0% in the 0-30k band and 16.0% in the 60-90k band, a 5.0-point spread.

Tyres is the most common advisory, noted on 23.9% of tests — work that passed today but is likely due soon.

The trend is worsening — 11.2% of tests failed in 2021 against 15.2% in 2025, the usual pattern as a fleet ages.
