The picture

Db11: a strong MOT record by UK norms

Across 2,372 MOT tests, the Db11 returns 94.4% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Windscreen damage and windscreen washers not working round out the top three. Average tested mileage sits at 16,143, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis

Best year to buy. Worst to avoid.

Best band to buy

98.3%

2021+ registration

Failures here are mostly wear items: damaged but not adversely affecting driver's view, has a cut in excess of the… — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.

Band to be cautious about

96.2%

Pre-2018 registration

On the older band (pre-2018), the data shows a 96.2% pass rate against a fleet average of 98.3% on the newer band. The main culprits logged at test: has a cut in excess of the…, damaged but not adversely affecting driver's view, and not working. Average mileage on test for this band is 24,026 miles — high-mileage wear items are a recurring theme.

Buying or keeping a Db11?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a Db11 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
