2015 Maserati Quattroporte — MOT failures & pass rate
879 MOT tests on the 2015 Maserati Quattroporte are in this dataset, and 86.1% of them passed. That is effectively the same as executive cars of a similar age (13.9% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (7.0%) and lighting & signalling (4.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, headlamp and headlamp aim — tread depth alone was recorded 40 times.
Mileage matters less than usual here: the 2015 Quattroporte fails 11.1% of the time in the 0-30k band and 11.3% at 90-120k, a spread of only 0.2 points.
Tyres is the most common advisory, noted on 24.3% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 5 | Emissions & environmental | 2.1% | 18 |
| 6 | Steering | 1.7% | 15 |
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 | 144 | 11.1% |
| 30-60k | 406 | 14.3% |

| 90-120k | 53 | 11.3% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Diesel | 536 | 12.9% |
| Petrol | 343 | 15.4% |
Trend over time

What to check before buying a 2015 Quattroporte
The failure pattern for this year is specific enough to inspect against: tyres accounted for 7.0% of tests. Start there.
- Tyres (7.0% 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.
- Lighting & signalling (4.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
