44,000 MOT tests on the Lexus NX in 2024, counted. 8.7% failed at the first attempt.
The short answer
8.7% of Lexus NX tests failed at the first attempt. Cars of the same ages averaged 16.3%, so the NX does better than most cars its age.
It fails most often on tyres (2.2% of tests), wipers, washers and windscreen (2% of tests) and lights and electrics (1.1% of tests).
By year of registration
Older cars fail more, whatever the model. So each year is shown beside the figure for all cars first used that year.

|---|---|---|---|---|
| 2021 | 7,011 | 5.2% | 10.9% | 22,000 15,800 to 29,400 |

What these figures can't tell you
An MOT is a safety and emissions test. These figures show how often the model fails that test. They say nothing about engines, gearboxes or electronics that break between tests, and how a car has been looked after matters more than its badge. The car you are looking at has its own MOT record, and that is the one to read.
Ask before you travel
- “How much tread is left on each tyre, and how old are they?”
- “Do the wipers and washers work properly, and is the windscreen chipped or cracked?”
- “Do all the lights work, including the number plate lights and brake lights?”
- “When were the brake pads and discs last changed?”
