2007 Aston Martin Db9 — MOT failures & pass rate
Across 3,514 MOT tests, the 2007 Aston Martin Db9 recorded a 91.0% pass rate. Coupes & convertibles of a similar age fail 21.6% of the time, so this is 12.6pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (4.4%) and brakes (2.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are position lamp, headlamp aim and coil spring — position lamp alone was recorded 74 times.
A 90-120k example is materially riskier than a 0-30k one: 17.3% versus 5.5%.
Advisories point at the next bill rather than this one: tyres was flagged on 13.9% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 13.9% | 490 |
| 2 | Brakes | 11.4% | 402 |
| 3 | Suspension | 4.0% | 140 |

| 5 | Lighting & signalling | 2.3% | 79 |
| 6 | Visibility | 2.0% | 69 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 1,116 | 5.5% |
| 30-60k | 1,770 | 9.1% |
| 60-90k | 518 | 14.3% |
| 90-120k | 81 | 17.3% |
Failure rate by age
Trend over time

What to check before buying a 2007 Db9
On a 2007 Db9, lighting & signalling is what the MOT record says goes wrong most — it appeared in 4.4% of tests. Check these areas before you commit.
- Lighting & signalling (4.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (2.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
