Is the Quattroporte getting worse?
The fail rate fell 0.7 points to 18.3% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.7 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 1,444 | 12 | 19% | 22.5% | |
| 2023 | 1,370 | 13 | 17.2% | 22.8% | |
| 2024 | 1,110 | 13 | 18.4% | 23.2% | |
| 2025 | 1,141 | 14 | 18.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Quattroporte at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Quattroporte in 2025, counted by how many tests each one appeared on.
- 1Rbt (sp): efficiency below requirements27 tests
- 2Wipers: does not clear the windscreen effectively21 tests
- 3Coil spring: fractured or broken20 tests
- 4Tread depth: tread depth below requirements of 1.6mm20 tests
- 5Condition: has ply or cords exposed20 tests
- 6Rbt (sp): efficiency less than 50% of the required value18 tests
- 7Malfunction indicator lamp: inoperative or indicates a malfunction15 tests
- 8SRS malfunction indicator lamp: warning lamp indicates a fault13 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Quattroporte collects 2.42 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Tread depth: tread depth below requirements of 1.6mm153 tests
- 2Brake discs: in such a condition that it is seriously weakened110 tests
- 3Brake pads: less than 1.5 mm thick81 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure56 tests
- 5Coil spring: corroded so that its cross sectional area is reduced and seriously weakened38 tests
- 6Brake discs: significantly and obviously worn38 tests
- 7Engine oil leaks: leaking excessively from engine32 tests
- 8Condition: has a cut in excess of the requirements deep enough to reach the ply or cords22 tests
Questions

What does a Maserati Quattroporte usually fail on?
The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 27 failed tests, followed by "Wipers: does not clear the windscreen effectively" and "Coil spring: fractured or broken". By section, brakes appears in 35.8% of failures, tyres appears in 34% of failures, lamps, reflectors and electrical equipment appears in 28.4% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 14.7%; at 14+ years it was 22.6%. The median Maserati Quattroporte tested in 2025 was 14 years old with 60,607 miles.
Is the Maserati Quattroporte getting less reliable?
The fail rate fell 0.7 points to 18.3% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.7 points, so it is holding up better than the fleet average for its age.
