Is the Ct getting worse?
The fail rate rose 3.1 points to 12.2% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.3 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 29,275 | 8 | 9.1% | 22.5% | |
| 2023 | 30,468 | 8 | 9.8% | 22.8% | |
| 2024 | 26,489 | 10 | 11.4% | 23.2% | |
| 2025 | 28,395 | 10 | 12.2% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Ct 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 Ct in 2025, counted by how many tests each one appeared on.
- 1Brake pads: less than 1.5 mm thick414 tests
- 2Headlamp: not working on dipped beam406 tests
- 3Condition: has a cut in excess of the requirements deep enough to reach the ply or cords352 tests
- 4Tread depth: tread depth below requirements of 1.6mm345 tests
- 5Wipers: does not clear the windscreen effectively325 tests
- 6Condition: has ply or cords exposed269 tests
- 7Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt247 tests
- 8Rbt (sp): efficiency below requirements218 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Ct collects 2.29 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 1.6mm3,660 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure2,662 tests
- 3Brake pads: less than 1.5 mm thick2,408 tests
- 4Brake discs: in such a condition that it is seriously weakened1,881 tests

Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 5.7%; at 14+ years it was 16.7%. The median Lexus Ct tested in 2025 was 10 years old with 75,337 miles.
Is the Lexus Ct getting less reliable?
The fail rate rose 3.1 points to 12.2% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.3 points, so it is holding up better than the fleet average for its age.
