Is the Model X getting worse?
The fail rate rose 4.9 points to 19.7% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 3,917 | 5 | 14.8% | 22.5% | |
| 2023 | 5,244 | — | 16.6% | 22.8% | |

| 2025 | 5,173 | — | 19.7% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Model X 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 Model X in 2025, counted by how many tests each one appeared on.
- 1Condition: has ply or cords exposed344 tests
- 2Tread depth: tread depth below requirements of 1.6mm179 tests
- 3Wipers: does not clear the windscreen effectively143 tests
- 4Condition: has a cut in excess of the requirements deep enough to reach the ply or cords136 tests
- 5Ball joint: ball joint excessively worn92 tests
- 6Pins and bushes: pin or bush excessively worn66 tests
- 7Brake pads: less than 1.5 mm thick60 tests
- 8Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt41 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Model X collects 2.34 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.
