Is the Db11 getting worse?
The fail rate rose 0.5 points to 4.1% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 5.5 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,044 | 4 | 3.6% | 22.5% | |
| 2023 | 2,260 | 5 | 4.6% | 22.8% | |

| 2025 | 2,354 | 7 | 4.1% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Db11 at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Db11 in 2025, counted by how many tests each one appeared on.
- 1Condition: has a cut in excess of the requirements deep enough to reach the ply or cords17 tests
- 2Washers: not working14 tests
- 3Registration plates: does not conform to the specified requirements8 tests
- 4Tread depth: tread depth below requirements of 1.6mm8 tests
- 5Rear fog lamp: not working7 tests
- 6Malfunction indicator lamp: inoperative or indicates a malfunction6 tests
- 7Condition: has a bulge, caused by separation or partial failure of its structure5 tests
- 8Headlamp aim: too high4 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Db11 collects 2.21 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.

- 2Condition: has a tear, caused by separation or partial failure of its structure155 tests
- 3Non-component advisories: Nail in tyre47 tests
