2006 Maserati Quattroporte — MOT failures & pass rate
The 2006 Maserati Quattroporte passed 80.9% of its 602 recorded MOT tests. That is 4.7 percentage points better than executive cars of a similar age, which fail at 23.8%. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (7.8%) and lighting & signalling (6.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rbt (sp) and coil spring — headlamp aim alone was recorded 27 times.
A 90-120k example is materially riskier than a 0-30k one: 25.5% versus 5.7%.
Tyres is the most common advisory, noted on 18.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 16.7% of tests failed in 2021 against 27.1% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 18.9% | 114 |
| 2 | Suspension | 16.3% | 98 |
| 3 | Brakes | 15.4% | 93 |
| 4 | Lighting & signalling | 5.1% | 31 |
| 5 | Emissions & environmental | 4.7% | 28 |
| 6 | Body, structure & corrosion | 2.8% | 17 |
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 | 35 | 5.7% |
| 30-60k | 198 | 17.2% |
| 60-90k | 267 | 20.2% |
| 90-120k | 94 | 25.5% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2006 Quattroporte
The failure pattern for this year is specific enough to inspect against: brakes accounted for 7.8% of tests. Start there.
- Brakes (7.8% 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.
- Lighting & signalling (6.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (6.0% 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.
