What the MOT record shows

No single area dominates — tyres (4.5%) and seat belts & restraints (3.0%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are tread depth, srs malfunction indicator lamp and brake pads — tread depth alone was recorded 194 times.

A 90-120k example is materially riskier than a 0-30k one: 13.1% versus 8.6%.

Fuel type barely separates them — diesel fails 10.4% of the time against 11.4% for petrol.

Advisories point at the next bill rather than this one: tyres was flagged on 23.8% of tests without failing them.

The trend is worsening — 9.9% of tests failed in 2022 against 12.1% in 2025, the usual pattern as a fleet ages.
