Is the Taycan getting worse?
The fail rate fell 1.9 points to 8.1% from 2023 to 2025, against a falling rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2023 | 1,843 | — | 10% | 22.8% | |
| 2024 | 3,570 | — | 8.3% | 23.2% | |
| 2025 | 5,435 | — | 8.1% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Taycan 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 Taycan in 2025, counted by how many tests each one appeared on.
- 1Condition: has ply or cords exposed261 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords196 tests
- 3Condition: has a bulge, caused by separation or partial failure of its structure120 tests
- 4Tread depth: tread depth below requirements of 1.6mm109 tests
- 5Registration plates: does not conform to the specified requirements52 tests
- 6Condition: has a tear, caused by separation or partial failure of its structure31 tests
- 7Condition: has a lump, caused by separation or partial failure of its structure26 tests
- 8Headlamp aim: too high23 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Taycan collects 1.87 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.
