26,426MOT tests in 2025

In 2025, 26,426 Mitsubishi Asx cars had a regular MOT in Great Britain. 73% passed first time, compared with 71% for all cars of the same ages, which makes the Asx about average. Adjusted for age, it ranks 113 of the 217 most-tested car models.

That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.

Pass rate by age

At 6 years old, 88% of Asxs passed first time (all cars that age: 84%). By 15 years, that figure is 61% (all cars: 59%). It beats the average car at every age with enough data, from 6 to 13 years.

What to check when buying a used Asx

Based on where the Asx fails more often than other cars, these are the checks worth making before you buy:

  • Steering: Feel for play or knocking through the wheel, and check power-steering fluid isn’t leaking. More
  • Brakes: Look through the wheels for lipped or scored discs, check the handbrake holds on a slope, and feel for pulling or vibration under firm braking. Repair guide
  • Suspension: Listen for knocks over speed bumps, look for leaking shock absorbers, and check the car sits level. Ask whether springs, bushes or drop links have been replaced. Repair guide

Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
