UK average, all cars

The RX runs 2.9 points behind the Lexus average. It is 6th of the 10 Lexus models in the data. The average RX arrived at its test 12.2 years old with 93,268 miles recorded.

A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.

RX MOT pass rate by age

The same 2025 tests split by the car's age at test.

Lexus RX cars aged 3 to 5 years passed 94.8% of MOT tests. For cars aged 11 years and over that fell to 72.7%, a drop of 22.2 percentage points.

3 to 5 years 5,195 94.8% 22.5 pts above
6 to 10 years 8,483 90.6% 18.3 pts above
11 years and over 21,212 72.7% In line

That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
