What the MOT record shows

No single area dominates — suspension (5.6%) and lighting & signalling (3.9%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are pins and bushes, wipers and headlamp aim — pins and bushes alone was recorded 344 times.

Condition tracks the odometer closely. Failures run at 9.0% in the 0-30k band and 20.0% in the 90-120k band, a 11.0-point spread — more than double.

Split by fuel, diesel examples fail 2.7pp more often than petrol ones (14.2% vs 11.5%) — worth weighing if you have a choice.

Advisories point at the next bill rather than this one: tyres was flagged on 26.2% of tests without failing them.

The trend is worsening — 7.2% of tests failed in 2021 against 14.3% in 2025, the usual pattern as a fleet ages.
