2022 Aston Martin Dbx V8 — MOT failures & pass rate
Across 398 MOT tests, the 2022 Aston Martin Dbx V8 recorded a 95.5% pass rate. All cars of a similar age fail 8.1% of the time, so this is 3.6pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and other defects.
What the MOT record shows
No single area dominates — tyres (4.3%) and lighting & signalling (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, tread depth and registration plates — headlamp aim alone was recorded 8 times.
Tyres is the most common advisory, noted on 15.3% of tests — work that passed today but is likely due soon.

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 | 347 | 4.0% |
| 30-60k | 51 | 7.8% |
What to check before buying a 2022 Dbx V8
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.3% of tests. Start there.
- Tyres (4.3% 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.
- Lighting & signalling (1.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Other defects (1.0% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
