Fiat 500: MOT pass rate and reliability data

The Fiat 500 fails its first MOT more often than the average UK car, by 5.1 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 306,338 individual Fiat 500 tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate71.6%
UK national average76.7%
Difference-5.1 points
Tests analysed306,338
Average mileage at test55,170 miles
Average year of manufacture2014
Reliability rank1,717 of 2,005 models

What this means if you are buying one

A 71.6% first-time pass rate means roughly 28 in every 100 Fiat 500s 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 Fiat 500 tested had covered 55,170 miles and was built around 2014.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Fiat 500 sits 5.1 points below the national average, ranked 1,717 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 Fiesta.

Looking at a specific Fiat 500 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 Fiat 500: £450 at UK salvage auction, from 62 ended listings, not independently confirmed sales.

Most common MOT advisories on a Fiat 500

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Fiat 500 before it actually fails on it.

From its 2008 to its 2020 model year, the Fiat 500's first-time pass rate has risen 30.6 points, from 60.8% to 91.4%, the usual pattern: a newer model year is a younger car today, so it fails less. First-time pass rate for each Fiat 500 year:

Fiat 500 by fuel type
