Is the X3 getting worse?
The fail rate fell 0.6 points to 16.1% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 92,811 | — | 16.7% | 22.5% | |
| 2023 | 97,388 | — | 16.7% | 22.8% | |
| 2024 | 88,824 | — | 16.9% | 23.2% | |
| 2025 | 94,929 | — | 16.1% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical X3 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 X3 in 2025, counted by how many tests each one appeared on.
- 1Coil spring: fractured or broken2,229 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords2,004 tests
- 3Tread depth: tread depth below requirements of 1.6mm1,601 tests
- 4Condition: has ply or cords exposed1,443 tests
- 5Side repeaters: not working1,354 tests
- 6Wipers: does not clear the windscreen effectively1,265 tests
- 7Brake pads: less than 1.5 mm thick985 tests
- 8Malfunction indicator lamp: inoperative or indicates a malfunction928 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical X3 collects 2.3 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.

- 2Brake pads: less than 1.5 mm thick6,638 tests
- 3Non-component advisories: Play in steering rack inner joint(s)6,137 tests
