2017 Lexus CT MOT pass rate: 91.9% (8,779 tests)
Is the 2017 CT getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 93.1% +7.4 vs same-age |
|
| 2024 | 91.6% +7.7 vs same-age |
|
| 2025 | 91.0% +8.6 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2017 CT?
