Fiat 500e — MOT statistics 2024

The Fiat 500e failed 14.85% of 2,572 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 122.1 (100 = expected for its age profile). This car fails its MOT about 22% more often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Renault Scenic (index 122.1) — the two published results are 0.0 index points apart.

Fiat 500e common problems: what actually fails the MOT

Suspension stands out at 11.3 per 100 tests, against 0.8 per 100 tests across UK electric vehicles of the same ages.

family vs national — matched to UK electric vehicles of the same ages — top component groups, per 100 tests. Legend: This family · National avg. Combined labels: family / national average. A gap here reflects how these vehicles are driven, used and maintained as well as how they were built — an MOT defect is a test outcome, not a breakdown.

Named defects ranked by how much more often they appear than the national average — not by raw rate.

Fiat 500e MOT advisories: what gets flagged

Tyres are highest at 26.0 per 100 tests; Non-component advisories are lowest at 3.0 per 100 tests — the gap is 23.0 per 100 tests.

higher bar = flagged more oftenadvisory items per 100 initial tests

Advisories are wear the tester noted but didn't fail — what will need money soon.

Tyres, brakes and suspension: Fiat 500e against cars of the same age

Failing items per 100 initial tests, 2019-2024. The comparison group is every petrol or diesel car tested at the same age, so weight and drivetrain show up rather than fleet age.

Adjusted for how much these are actually driven

The headline index adjusts for the fleet's age. Wear, though, follows mileage: a three-year-old taxi and a three-year-old garage queen sit in the same age band. These two rows compare every car with vehicles of the same age, and then with vehicles of the same age and the same annual mileage, 2019-2024, on 2,576 tests. Both stand on the six-year corpus so they are measured on identical data — compare them with each other, not with the headline index above, which is measured on 2024 alone.

Split by how much each car is driven. This is a split by annual mileage, not by body type — the MOT record does not say whether a car is a conversion. Within each band the index compares with vehicles of the same age driven as much.

Mileage matters here: matching on how much these are driven moves the figure by 42.5 points — this fleet is driven less than the vehicles it is measured against, so the age-only view flatters it — but it does not change which side of normal the car sits on. One limit to keep in mind: mileage is partly a result of how often a car breaks down — one that spends weeks in the workshop covers fewer miles — so the mileage-matched figure can understate a real weakness. Tests with no usable odometer reading are left out of it.

How the Fiat 500e compares with cars of its own age and size

Not against the whole fleet — against cars of the same size class tested at the same age, 2019-2024.

Raw first-time failure rates within each age, so fleet age cannot flatter either side. A positive difference means this model fails more often than its own class at that age.

How does the Fiat 500e perform as it gets older?

The 500e at age 3 stands out at 15.1%, against 12.4% for all vehicles of the same age.

Chart axes: car age, years · failure-rate scale 0–16%.

Takeaway: solid line: this family; dashed: all cars.

How dangerous are Fiat 500e MOT failures?

Major defects are well below the reference at 14.6 per 100 tests, against 52.8 per 100 tests nationally.

Does the month of a Fiat 500e MOT matter?

May is highest at 20.6%; Jan is lowest at 0.0% — the gap is 20.6 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: -1%–33%.

bars: Fiat 500e · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 20.6 percentage points — noticeable seasonality. Seasonality partly reflects registration-date clustering, not weather.

Before reading the shape: most of it is not about cars. Britain changes its registration plates twice a year, and 18.9% of these cars were first registered in March with another17.1% in September — 36% in two months against the 17% an even spread would give. An MOT falls due three years after first registration, so the buying calendar becomes the testing calendar. That shapes how many cars are tested each month — not how often they fail: the busiest months here are not the worst ones, so read the failure line on its own and the volume behind it separately.

Fiat 500e average mileage by age

At age 3, the middle half of 500es runs from 8,665 miles to 19,904 miles, against 13,255 miles as the median.

further right = more milesmedian is the typical car; band is p25–p75

line: median · band: middle half of the fleet (p25–p75)

A typical 3-year-old 500e has ~13,255 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the Fiat 500e fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 2,576 tests, 2019-2024.

Raw pass/fail rates, not age-adjusted: fleets differ by region. England is split north of Sheffield, between Sheffield and Oxford, and south of it.

Fiat 500e faults that come together

Suspension + Tyres stand out at 2.71×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Suspension» and «Tyres» appear together 2.71× more often than chance (23 co-occurrences in the same test; 36 pairs compared).

Lift = how many times more often both groups appear on the same test than if independent. A pair is listed from 5 tests with both faults; the lift is shown from 20, and called above chance only when its 95% interval excludes 1 (see rough estimates).

Fiat 500e rust problems: where they corrode

Salt-belt exposure is well below the reference at 6th percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This Fiat 500e has too few tests to judge for corrosion once age is held constant, and its owners live in areas that are gentler than most for the models we publish.

Corrosion is the one failure mode that is as much about geography as about the car. We keep the two apart on purpose: a model can look rusty simply because it is popular in Scotland, and a model can look clean simply because it is bought in Surrey. Blending them into a single score would hide which of the two is doing the work.

Exposure is this model's tests weighted by an area corrosion index built from frost days, salt load and distance to the coast — the composite validated at r = 0.42 against corrosion defects we actually record. It is published as a rank, not a raw score, because every mainstream model skews towards low-corrosion areas for the simple reason that most of Britain's cars are in the south. Susceptibility is standardised to the national age profile, so an old fleet does not get labelled a rusty model.

Fiat 500e MOT: quick answers

Fiat 500e MOT Risk Index stands out at 122.1, against 100 for a car with the same age profile.

What is the Fiat 500e first-time MOT pass rate?

85.15% of first attempts passed in 2024 (2,572 tests). This is the first-time figure: retests after repair are excluded. Basis: first-time, excluding retests.

Why does this number differ from other sites?

Other sites often report a pass rate that includes retests or counts all attempts. Our 14.85% figure is the first-time initial failure rate, using 2,572 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 122.1 is shown separately because raw rates compare fleet age as well as cars.
