2019 Aston Martin Db11 — MOT failures & pass rate
The 2019 Aston Martin Db11 passed 95.0% of its 2,145 recorded MOT tests. Against coupes & convertibles of a similar age (8.6% fail rate), the 2019 Db11 comes out 3.6pp better. Failures cluster in lighting & signalling, tyres and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (2.1%) and tyres (2.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are switch, headlamp aim and washers — switch alone was recorded 31 times.
Advisories point at the next bill rather than this one: tyres was flagged on 15.3% of tests without failing them.
The trend is worsening — 4.1% of tests failed in 2022 against 6.2% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Db11
On a 2019 Db11, lighting & signalling is what the MOT record says goes wrong most — it appeared in 2.1% of tests. Check these areas before you commit.
- Lighting & signalling (2.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (2.0% 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 (0.8% 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.
