Mitsubishi Asx (2020)
2020 Mitsubishi Asx
CarHunch analysed 139 real MOT records for the 2020 Mitsubishi Asx. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Mitsubishi ASX is a strong performer, with a 93.9% first-time pass rate that sits well ahead of the UK average of 80%—a 14-point margin that signals good build quality and owner maintenance. Dangerous defects are rare at just 2.9%, so safety concerns are minimal for potential buyers.
At 28,449 miles median mileage, these vehicles are lightly used for their age, which explains the low failure rate of 0.24 per car and modest advisory count of 2.1—this is a cohort that's been looked after. Before purchase, check the service history carefully and have an independent inspection focus on whether routine maintenance has been done, as these cars clearly respond well to proper care.
What to check before buying a 2020 Mitsubishi Asx
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
