Is the Panamera getting worse?
The fail rate fell 0.1 points to 10.4% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.2 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 6,406 | 7 | 10.5% | 22.5% | |
| 2023 | 6,464 | 8 | 11.2% | 22.8% | |
| 2024 | 5,654 | 9 | 11.2% | 23.2% | |
| 2025 | 6,171 | 9 | 10.4% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Panamera 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 Panamera in 2025, counted by how many tests each one appeared on.
- 1Condition: has ply or cords exposed131 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords111 tests
- 3Tread depth: tread depth below requirements of 1.6mm104 tests
- 4Coil spring: fractured or broken74 tests
- 5Malfunction indicator lamp: inoperative or indicates a malfunction49 tests
- 6Condition: has a bulge, caused by separation or partial failure of its structure42 tests
- 7Tyre pressure monitoring system: malfunctioning or obviously inoperative37 tests
- 8Wipers: does not clear the windscreen effectively29 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Panamera collects 2.09 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 1.6mm1,001 tests
- 2Brake pads: less than 1.5 mm thick369 tests
- 3Brake discs: in such a condition that it is seriously weakened279 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure179 tests
- 5Condition: has a cut in excess of the requirements deep enough to reach the ply or cords175 tests
- 6Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm159 tests
- 7Non-component advisories: Nail in tyre156 tests
- 8Engine oil leaks: leaking excessively from engine113 tests
Questions
What is the Porsche Panamera MOT pass rate?

What does a Porsche Panamera usually fail on?
The single most common failure is "Condition: has ply or cords exposed", recorded on 131 failed tests, followed by "Condition: has a cut in excess of the requirements deep enough to reach the ply or cords" and "Tread depth: tread depth below requirements of 1.6mm". By section, tyres appears in 57.1% of failures, lamps, reflectors and electrical equipment appears in 15.5% of failures, suspension appears in 14.7% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 8.9%; at 14+ years it was 11.8%. The median Porsche Panamera tested in 2025 was 9 years old with 63,056 miles.
Is the Porsche Panamera getting less reliable?
The fail rate fell 0.1 points to 10.4% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.2 points, so it is holding up better than the fleet average for its age.
