Lexus CT: what fails at MOT
42,000 MOT tests on the Lexus CT in 2024, counted. 15.9% failed at the first attempt.
The short answer
15.9% of Lexus CT tests failed at the first attempt. Cars of the same ages averaged 25.2%, so the CT does better than most cars its age.
It fails most often on lights and electrics (4.6% of tests), tyres (3.7% of tests) and brakes (2.3% 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.
| First used | Tests | Failed first time | All cars that year | Typical mileage |
|---|---|---|---|---|
| 2021 | 437 | 6.2% | 10.9% | 30,900 19,200 to 40,900 |
| 2020 | 1,807 | 10.0% | 11.5% | 25,300 17,000 to 37,400 |
| 2019 | 2,756 | 9.7% | 13.4% | 34,900 24,600 to 50,900 |
| 2018 | 3,662 | 9.7% | 15.6% | 41,300 28,300 to 57,400 |
| 2017 | 3,773 | 11.8% | 18.2% | 47,200 34,200 to 64,700 |
| 2016 | 3,926 | 12.5% | 21.3% | 60,100 42,500 to 83,500 |

| 2014 | 4,890 | 14.3% | 27.7% | 76,700 55,500 to 104,300 |
| 2013 | 4,884 | 21.2% | 30.6% | 84,800 62,800 to 114,000 |
| 2012 | 6,012 | 20.9% | 33.4% | 96,900 71,800 to 126,000 |
| 2011 | 5,302 | 23.2% | 36.1% | 100,300 73,400 to 131,700 |
Green is at least three points better than other cars that year, red at least three points worse. Typical mileage is the middle reading at the test, with the range the middle half of cars fell in.

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
- “Do all the lights work, including the number plate lights and brake lights?”
- “How much tread is left on each tyre, and how old are they?”
- “When were the brake pads and discs last changed?”
- “Do the wipers and washers work properly, and is the windscreen chipped or cracked?”
