What the MOT record shows

No single area dominates — lighting & signalling (9.3%) and suspension (8.7%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are coil spring, headlamp aim and service brake performance — coil spring alone was recorded 66 times.

Mileage is the strongest signal on the record: 19.4% of 0-30k cars fail, rising to 27.3% once past 90-120k.

Tyres is the most common advisory, noted on 24.1% of tests — work that passed today but is likely due soon.

The trend is worsening — 16.5% of tests failed in 2021 against 22.2% in 2025, the usual pattern as a fleet ages.
