Aston Martin Db11 MOT pass rate & common failures
11,240 MOT tests on the Aston Martin Db11 (2016–2024) give it a 95.9% pass rate. Coupes & convertibles of a similar age fail 9.2% of the time, so this is 5.1pp better than the group it competes with. Its most common failure areas are lighting & signalling, tyres and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (1.6%) and tyres (1.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, washers and registration plates — headlamp aim alone was recorded 100 times.
Mileage matters less than usual here: the Db11 fails 4.0% of the time in the 0-30k band and 3.6% at 60-90k, a spread of only 0.4 points.
Advisories point at the next bill rather than this one: tyres was flagged on 14.9% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a Aston Martin Db11
- Lighting & signalling (1.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (1.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (0.7% 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.
