Ford Fiesta: MOT pass rate and reliability data

The Ford Fiesta fails its first MOT more often than the average UK car, by 5 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 1,352,968 individual Ford Fiesta tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate71.7%
UK national average76.7%

Average mileage at test70,404 miles
Average year of manufacture2013
Reliability rank1,713 of 2,005 models

What this means if you are buying one

A 71.7% first-time pass rate means roughly 28 in every 100 Ford Fiestas presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average Ford Fiesta tested had covered 70,404 miles and was built around 2013.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Ford Fiesta sits 5 points below the national average, ranked 1,713 of 2,005 models. On one bought as repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

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. See how it stacks up against the Ford Focus.

Looking at a specific Ford Fiesta 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 the median recorded closing bid for a damaged Ford Fiesta: £400 at UK salvage auction, from 204 ended listings, not independently confirmed sales.
