Should I check the MOT history before buying a 2020 Mitsubishi Asx?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2020 Mitsubishi Asx?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2020 Mitsubishi Asx?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2020 Mitsubishi Asx reliable?

Based on MOT data from 139 vehicles, the 2020 Mitsubishi Asx has a first-time MOT pass rate of 93.9%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

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.
