Fiat 500 reliability: what 1m MOT tests show

Across 994,670 MOT tests on Fiat 500 cars first used between 2008 and 2022, 68.3% passed first time. The figure for all cars is 71.7%. Compared only with cars tested at the same age, the 500 is 3.7 points behind, so the model itself is below average, not just old. At its first MOT, at three years old, 88.9% of 500s pass; the national figure for three-year-old cars is 87.9%. The weakness shows with age rather than from new. The most common reason for a fail is a worn suspension bush.

The 500's weak points

Of every hundred 500s that fail, about 16 are marked down for a worn suspension bush and 7 for shock absorbers bush worn. Percentages can add to more than 100 because one failed test often records several defects.

1Suspension bush: excessively worn15.7%
2Shock absorbers: bush worn6.9%
3Shock absorbers: leaking5.6%
4Ball joint: excessively worn4.6%
5Tyre: tread below the 1.6mm legal minimum4.5%
6Wiper: not clearing the screen3.2%

Worn bushes and ball joints build up slowly. A vague or clunky front end before the test is worth a garage check, since suspension is where tests are lost.

Advisories to expect on a 500

An advisory is the tester telling you what fails next year. On the 500 the usual suspects are tyre tread below the legal minimum (17.2% of tests) and a damaged tyre sidewall (11.5%). Nationally, an advisory on lights becomes a failure 36.1% of the time.

Tyre: tread below the 1.6mm legal minimum17.2%
Tyre: sidewall tear or separation11.5%
Suspension bush: excessively worn8.7%
Coil spring: corroded and weakened6.8%
Brake discs: seriously weakened5.6%

Petrol, diesel or hybrid 500?

Among Fiat 500 cars, petrol versions pass 68.5% of the time and diesel versions 57.8%, a gap of 10.7 points. Diesels tend to be bought for high mileage, which shows up at the test as wear.

Pass rate by year of first use

The oldest 500s on the road, from 2008, pass 54.8% of the time; the 2022 cars pass 90.6%. Read the table as an age curve first and a quality ranking second.

How mileage changes the 500's odds

On the 2014 cars, a 500 under 40,000 miles passes 76.2% of the time; one over 100,000 passes 53.8%. When comparing two used 500s, the odometer tells you more than the year.

Fiat stablemates and rivals

Set against the rest of the Fiat range, which averages 67%, the 500 at 68.3% is above par. See the Fiat range at the MOT. Buyers weighing a 500 against other cars of similar popularity often compare it with the Mercedes-Benz A-Class (78.1%) and Nissan Juke (70%). The reliability index for all makes and models puts them side by side, and the UK pass rates by age and fuel give the baseline.

Questions people ask

Is the Fiat 500 reliable?

On MOT evidence the Fiat 500 is below average. It passes 68.3% of tests against 71.7% for all cars, and trails cars of the same age by 3.7 points. 88.9% pass their first MOT at three years old. Figures from 994,670 DVSA tests.

What are the most common Fiat 500 MOT failures?

A worn suspension bush (15.7% of failed tests), shock absorbers bush worn (6.9%) and a leaking shock absorbers (5.6%). Worn bushes and ball joints build up slowly. A vague or clunky front end before the test is worth a garage check, since suspension is where tests are lost.

Which Fiat 500 year is the most reliable?

Among years with a large sample, 2022 cars have the highest pass rate at 90.6% and 2008 cars the lowest at 54.8%. Newer years pass more because they are younger, so compare a specific car's year against the table above rather than against the overall figure.

What advisories does a Fiat 500 usually get?

Tyre tread below the legal minimum is the most frequent, noted on 17.2% of all 500 tests, then a damaged tyre sidewall (11.5%). An advisory passes the car today but marks the item most likely to fail next year.

How many miles a year does a Fiat 500 do?

About 5,551 miles a year on average, calculated from the odometer readings recorded at consecutive MOTs. That is below the UK average of roughly 7,400.

How do I check a particular Fiat 500?

The figures describe the whole fleet. For one car, enter its registration in the free MOT check to see its own test history, advisories and mileage, set against these averages for its year.

Looking at a specific Fiat 500?

Enter the registration to see its own MOT history, advisories and mileage set against these figures, including whether it has done more or fewer than the 5,551 miles a year typical of the model.

Source: DVSA anonymised MOT tests and results, 2023 to 2025. Class 4 cars, normal tests only; a pass after rectification counts as an initial failure. Age-adjusted figures compare the model's pass rate at each age with the national rate at the same age. Methodology.
