2009 Maserati Quattroporte — MOT failures & pass rate
Across 558 MOT tests, the 2009 Maserati Quattroporte recorded an 82.8% pass rate. That is 4.5 percentage points better than executive cars of a similar age, which fail at 21.7%. Failures cluster in suspension, tyres and visibility.
What the MOT record shows
No single area dominates — suspension (7.7%) and tyres (5.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, washers and headlamp aim — coil spring alone was recorded 27 times.
Mileage matters less than usual here: the 2009 Quattroporte fails 14.3% of the time in the 0-30k band and 12.2% at 90-120k, a spread of only 2.1 points.
Advisories point at the next bill rather than this one: suspension was flagged on 25.3% of tests without failing them.
The trend is worsening — 16.9% of tests failed in 2021 against 20.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2009 Quattroporte
On a 2009 Quattroporte, suspension is what the MOT record says goes wrong most — it appeared in 7.7% of tests. Check these areas before you commit.
- Suspension (7.7% 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.
- Tyres (5.6% 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 (5.4% 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.
