2014 Maserati Quattroporte — MOT failures & pass rate
Across 738 MOT tests, the 2014 Maserati Quattroporte recorded an 86.2% pass rate. Executive cars of a similar age fail 15.4% of the time, so this is 1.6pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
Tyres dominates the failure mix at 10.0% of all tests — 5.3 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are tread depth, headlamp aim and wipers — tread depth alone was recorded 22 times.
Mileage is the strongest signal on the record: 10.7% of 0-30k cars fail, rising to 16.3% once past 90-120k.
Advisories point at the next bill rather than this one: tyres was flagged on 20.2% of tests without failing them.
The trend is improving — the fail rate fell from 13.5% in 2021 to 10.8% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2014 Quattroporte
On a 2014 Quattroporte, tyres is what the MOT record says goes wrong most — it appeared in 10.0% of tests. Check these areas before you commit.
- Tyres (10.0% 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 (4.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.0% 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.
