2017 Maserati Quattroporte — MOT failures & pass rate
Across 419 MOT tests, the 2017 Maserati Quattroporte recorded an 89.0% pass rate. That is effectively the same as executive cars of a similar age (11.5% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
One area stands out: tyres, recorded in 7.9% of tests against 2.6% for the next-worst category.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 26 times.
Mileage matters less than usual here: the 2017 Quattroporte fails 9.0% of the time in the 0-30k band and 10.9% at 60-90k, a spread of only 1.9 points.
Tyres is the most common advisory, noted on 23.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 11.4% in 2021 to 9.0% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2017 Quattroporte
The failure pattern for this year is specific enough to inspect against: tyres accounted for 7.9% of tests. Start there.
- Tyres (7.9% 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 (2.6% 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.
- Lighting & signalling (1.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
