Is the Db7 getting worse?
The fail rate fell 0.3 points to 12.7% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (-2.4 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,008 | 22 | 13% | 22.5% | |
| 2023 | 1,970 | 23 | 13.3% | 22.8% | |
| 2024 | 1,588 | 24 | 12.4% | 23.2% | |
| 2025 | 1,689 | 25 | 12.7% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Db7 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 Db7 in 2025, counted by how many tests each one appeared on.
- 1Rbt (sp): efficiency below requirements22 tests
- 2Wipers: does not clear the windscreen effectively21 tests
- 3SRS malfunction indicator lamp: warning lamp indicates a fault19 tests
- 4Rbt (sp): efficiency less than 50% of the required value17 tests
- 5Anti-lock braking system: warning lamp indicates an ABS fault16 tests
- 6Parking brake performance: inoperative on one side16 tests
- 7Headlamp aim: too high15 tests
- 8Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits15 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Db7 collects 3.05 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.
- 1Coil spring: corroded so that its cross sectional area is reduced and seriously weakened122 tests
- 2Engine oil leaks: leaking excessively from engine113 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure99 tests
- 4Pins and bushes: pin or bush excessively worn91 tests
- 5Wheel bearings: has excessive play76 tests
- 6Rigid brake pipes: excessively corroded55 tests
- 7Tread depth: tread depth below requirements of 1.6mm54 tests
- 8Brake discs: in such a condition that it is seriously weakened49 tests
Questions
What is the Aston Martin Db7 MOT pass rate?
87.3% of the 1,689 Aston Martin Db7 first-attempt MOTs in 2025 passed. The fail rate of 12.7% compares with 22.6% across all cars. A further 1.2% passed after a defect was fixed during the test visit.
What does a Aston Martin Db7 usually fail on?
The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 22 failed tests, followed by "Wipers: does not clear the windscreen effectively" and "SRS malfunction indicator lamp: warning lamp indicates a fault". By section, brakes appears in 36.3% of failures, suspension appears in 26% of failures, lamps, reflectors and electrical equipment appears in 20% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 0%; at 14+ years it was 12.7%. The median Aston Martin Db7 tested in 2025 was 25 years old with 50,366 miles.
Is the Aston Martin Db7 getting less reliable?
The fail rate fell 0.3 points to 12.7% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (-2.4 points). Read it as the fleet getting older rather than the model changing.
