2007 Maserati Quattroporte — MOT failures & pass rate
996 MOT tests on the 2007 Maserati Quattroporte are in this dataset, and 79.0% of them passed. Executive cars of a similar age fail 23.2% of the time, so this is 2.2pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (8.6%) and brakes (8.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), coil spring and headlamp aim — rbt (sp) alone was recorded 60 times.
A 90-120k example is materially riskier than a 0-30k one: 29.9% versus 9.7%.
Advisories point at the next bill rather than this one: tyres was flagged on 22.2% of tests without failing them.
The trend is improving — the fail rate fell from 21.1% in 2021 to 18.9% in 2025, as the worst-kept examples leave the fleet.

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 | 22.2% | 221 |
| 2 | Brakes | 20.0% | 199 |
| 3 | Suspension | 18.5% | 184 |
| 4 | Other defects | 4.1% | 41 |
| 5 | Lighting & signalling | 3.3% | 33 |
| 6 | Visibility | 3.0% | 30 |
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 | 62 | 9.7% |
| 30-60k | 310 | 18.4% |
| 60-90k | 429 | 21.4% |
| 90-120k | 157 | 29.9% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2007 Quattroporte
On a 2007 Quattroporte, lighting & signalling is what the MOT record says goes wrong most — it appeared in 8.6% of tests. Check these areas before you commit.
- Lighting & signalling (8.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.1% 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.
- Suspension (6.8% 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.
