39,000 MOT tests on the Mitsubishi ASX in 2024, counted. 23.2% failed at the first attempt.
The short answer
23.2% of Mitsubishi ASX tests failed at the first attempt. Cars of the same ages averaged 24.4%, so the ASX is about average for its age.
It fails most often on brakes (6.1% of tests), suspension (4.8% of tests) and lights and electrics (3.7% of tests). It fails on brakes more often than most cars its age.

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
- “When were the brake pads and discs last changed?”
- “Have any suspension parts been replaced, such as springs, ball joints or bushes, and can I see the invoice?”
- “Do all the lights work, including the number plate lights and brake lights?”
- “Do the wipers and washers work properly, and is the windscreen chipped or cracked?”
