2020 Lexus RX MOT pass rate: 96.6% (5,056 tests)
Is the 2020 RX getting worse?
Pass rate of 2020-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 97.3% +6.4 vs same-age |
|
| 2024 | 96.4% +6.4 vs same-age |
|
| 2025 | 96.2% +7.3 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 2020 RX?
The median tested example shows 28,332 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
