Expert verdict
Tyres: 2.9× the national share
Tyres make up 57.7% of everything recorded on the 2016 Aston Martin Db9, against 19.8% nationally — 37.9 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 84.0% and this one manages 97.6% — 13.6 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 24% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2016 DB9
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2016 DB9
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 0.4% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the tyre tread 0.4% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
-
Check tyre pressures and valves 0.4% of tests
“tyre pressure monitoring system malfunctioning or obviously inoperative”
Set the pressures to the figures on the door pillar, not the tyre wall, and check the valves do not hiss. A leaking valve is a two-minute fix that fails a test.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What testers noted without failing the car

| Tread depth below requirements of 1.6mm Tyres | Advisory | 4.6% | £45–95 |
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 2.8% | £45–95 |
