Mitsubishi Asx: MOT pass rate and reliability data

The Mitsubishi Asx passes its MOT first time more often than the average UK car, by 2 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 27,287 individual Mitsubishi Asx tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 78.7% first-time pass rate means roughly 21 in every 100 Mitsubishi Asx presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Mitsubishi Asx tested had covered 73,941 miles and was built around 2015.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a Mitsubishi Asx bought as a repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Mitsubishi Asx rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see what damaged Mitsubishi Asx actually sold for at UK salvage auction.
