2018 Maserati Granturismo — MOT failures & pass rate
The 2018 Maserati Granturismo passed 89.9% of its 546 recorded MOT tests. Coupes & convertibles of a similar age fail 9.0% of the time, so this is 1.0pp worse than the group it competes with. Failures cluster in tyres, visibility and suspension.
What the MOT record shows
One area stands out: tyres, recorded in 7.3% of tests against 1.8% for the next-worst category.
At component level the recurring items are tread depth, wipers and coil spring — tread depth alone was recorded 13 times.
Tyres is the most common advisory, noted on 16.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.5% of tests failed in 2021 against 11.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 Granturismo
The failure pattern for this year is specific enough to inspect against: tyres accounted for 7.3% of tests. Start there.
- Tyres (7.3% 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.
- Visibility (1.8% 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.
- Suspension (1.3% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
