2018 Lexus RX MOT pass rate: 95.7% (5,151 tests)
Is the 2018 RX getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 96.7% +8.6 vs same-age |
|
| 2024 | 95.6% +9.4 vs same-age |
|
| 2025 | 94.6% +9.9 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 2018 RX?
