Is a Ford Fiesta ULEZ compliant?
The share of classifiable 2024 Ford Fiesta MOT tests likely ULEZ compliant by first-registration date is 83.1%.
Based on 1,959,360 classifiable initial MOT tests. This describes the tested fleet, not a specific car. MOT data do not record Euro class, so likely compliance is inferred from fuel and first-registration date. For the only authoritative answer, check the registration with TfL's official ULEZ checker.

| Dec | 35.25% | 26.29% | +9.0 pp |
Takeaway: the spread between best and worst month is 3.7 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 19.5% of these cars were first registered in March with another17% in September — 37% 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. Peaks here mark when cars are tested, not when they are worse.

Why do areas differ?
For each external factor we correlate the area fail rate with the factor across postcode areas that have ≥800 tests of this family, then compare the bottom vs top fifth (quintile) of the factor. Correlation, not causation — factors travel together (the north is colder and often poorer; urban areas are denser and less salted). Road surface condition is joined now, for the 91 English areas the DfT publishes, and it explains nothing: the correlation with suspension failures is −0.01 and with body and structure failures 0.07. Potholes wreck wheels and tyres between tests, but by the time a car reaches the bay the road it drives on leaves no measurable trace.
In areas with the highest mot centre density this model fails 7.5 pp more often than in the lowest fifth (r=0.57, n=116 areas with ≥800 tests).
In areas with the highest urban share this model fails 6.7 pp less often than in the lowest fifth (r=-0.46, n=116 areas with ≥800 tests).
In areas with the highest terrain gradient this model fails 2.5 pp more often than in the lowest fifth (r=0.31, n=69 areas with ≥800 tests).
| Factor | Low Q | High Q | Gap | Correlation |
|---|---|---|---|---|
| MOT centre density | 29.4% | 37.0% | +7.6 pp | r=0.57 |
| Urban share | 36.6% | 29.9% | -6.7 pp | r=-0.46 |
| Terrain gradient | 34.5% | 37.0% | +2.5 pp | r=0.31 |
Factors that only mean something combined
Some conditions are useless on their own and informative multiplied together. Frost days alone say little — Britain barely freezes. Salt tonnage alone says little — it tracks frost. Distance to the sea alone says little. Multiply the first two and divide by the third and you get an index of how hard an area attacks a car's underside, and it lines up with the corrosion defects we actually record. We built five such combinations and tested each against our own data. Three survived; two did not, and the failures are listed here on purpose — a proxy that was never checked is decoration. One survivor only survived on the second attempt: built from a crude stand-in for street parking it failed outright, and rebuilt from the census — terraced streets carrying more cars than they have driveways — it works, and carries information the salt index does not.
| Composite | Built from | Tested against | r | Verdict |
|---|---|---|---|---|
| Underbody corrosion | frost days × salt load ÷ (distance to coast + 1) | share of tests with a corrosion defect | +0.42 | holds (116 areas) |
| Tyre wear | rain days × annual miles ÷ age at first tyre advisory | share of tests failing on tyres | +0.45 | holds (116 areas) |
| Overnight corrosion | terraced housing × cars per household × frost days | share with a corrosion defect | +0.41 | holds (102 areas) — and adds signal beyond the first index |
| Deferred maintenance | deprivation × advisory-to-failure conversion ÷ labour rate | cars repeating the same advisory | −0.26 | fails (118 areas) |
| Powertrain stress | engine capacity ÷ kerb weight | suspension, brake and emissions failures | −0.16 | fails (22 models) |
The deprivation result is the one worth dwelling on. The intuition that poorer areas defer repairs is strong enough that most people treat it as established. We tested it twice — once on raw failure rates (r = 0.04) and again, more fairly, on whether an advisory turns into a failure — and it did not hold any of the three times we tried it — on raw failure rates, on advisory-to-failure conversion, and again with deprivation measured properly inside each nation rather than England alone. We are closing it. What does predict local failure rates is the density of test centres, which is a statement about testing, not about cars.

Every dot is a postcode area — size = how many were tested there, colour = share failing. These figures are not age-adjusted: coastal and rural areas often run older fleets and salted roads, so higher raw fail rates do not automatically mean a worse local stock of this model.

At matched ages 5–14, cars averaging under 5k miles/year fail at 21.1% vs 38.2% for 8–12k miles/year — 17.1 pp lower (n_low=404,116, n_normal=373,400). In this family low annual use is associated with fewer MOT fails, not more — the ‘garage queen’ penalty is not visible in overall fail rates. Diesel alone: 28.4% low-use vs 43.4% normal (-15.0 pp).

Since 2021 every new car in Europe records its own fuel use, and the regulator publishes what those meters say next to the laboratory figure the car was sold on. For this manufacturer the worst gap is 19.83% — petrol cars of 2023 burning 6.72 litres per 100 km against an official 5.61, with CO₂ higher by the same proportion.
This is the manufacturer, not the model. The regulator aggregates by legal manufacturer (FORD WERKE GMBH), so these figures are context for the badge rather than a measurement of this particular car — a point we would rather state plainly than let a reader assume otherwise. The gap itself is not a scandal, it is the known distance between a standardised laboratory cycle and real roads, but it is the distance you actually pay for at the pump. The plug-in hybrid rows are not a data error and deserve a sentence of their own: an official figure of 1.85 litres assumes the car spends most of its life on the battery, and the meters say these ones burned 5.92. Owners are not plugging them in, and a plug-in hybrid that is never charged is simply a heavy petrol car.

Splitting this model by fuel alone hides the thing that actually differs. Within the same badge, the diesel 1.2–1.5 runs at 113.4 against this model's own age norm while the petrol 1.8–2.0 runs at 74.7 — a spread of 38.7 points between two cars that share a name.
Read this one with more care than the rest of the page. Age is held constant, but who buys which engine is not: the largest capacity in a range is often a performance or executive variant that is garaged, cherished and lightly driven, while the smallest is frequently a fleet or entry car worked hard from new. The gap below is real in the test records; how much of it is the engine and how much is the owner, this data cannot separate. Bands under 5,000 tests are not shown.

The best build year here is 2018 and the weakest is 2016. Comparing build years sounds simple and is not: within a single year of testing, a car's build year and its age are the same number, so a naive comparison of years is a comparison of ages wearing a disguise. Each year below is measured against the same model at the same age in other cohorts, across six years of testing — 19 of 23 years come out distinguishable from their own model's age norm.
Two limits worth knowing before you act on this. Age, test year and build year are locked together by arithmetic, so the test-year effect is taken from the observed national failure level of each year rather than estimated — it is an adjustment, not a solution. And for cars built before about 2005, a good score says more about which examples survived to be tested than about how that year was built: survivors are self-selected for care.
Ford Fiesta MOT repair costs
The MOT-failure repair budget per test runs from £124.48 to £236.51, against £54.85 for the test itself.
bigger number = costs morepounds per test, MOT-failing faults only
| Component | Fails per 100 tests | Typical repair | Its price | Contribution |
|---|---|---|---|---|
| Suspension | 28.6 (nat. 19.9) | Suspension coil spring (single corner) | £180 | £51.48 |
| Lamps, reflectors and electrical equipment | 29.9 (nat. 23.52) | Battery replacement (standard 12V lead-acid) | £140 | £41.86 |
| Brakes | 12.9 (nat. 14.34) | Front brake pads (parts + labour, typical hatchback) | £150 | £19.35 |
| Tyres | 13.1 (nat. 10.27) | Tyre (single mid-range 16" fitted) | £90 | £11.79 |
Multiply how often each component fails on this model by what that repair usually costs, and you get the amount an owner should expect to budget per test for MOT-failing faults only — roughly £124 to £237, on top of the test fee itself. It is a budgeting figure, not a quote: the spread between a set of pads and a set of discs is most of the range.
Prices are modal quotes from a hand-kept catalogue of published UK garage guides — we do not scrape the booking sites, their terms forbid it, so this list is short and updated by hand with a source and date against each line. Each line prices one typical repair in that group, not a full remedy, and only groups our catalogue actually covers are counted. The contrast worth noticing is the second card: the legal maximum for the test has been £54.85 since 2010, while the repairs it uncovers have followed inflation the whole time.
For scale from a different direction: Warrantywise, which sees used-car warranty claims rather than test failures, puts the average claim at £2,052 across the ten highest-claim models it ranks and £539 for Honda, the lowest-claim make in its index (Warrantywise index 2026, 1.6 million claims, cars aged 3–15). Those sit an order of magnitude above the figures in this table, and the gap is the point: a warranty claim is a gearbox or an engine, which almost never fails an MOT, while the faults that do fail one are corrosion, lamps and tyres, which no warranty pays for. The two numbers answer different questions and neither replaces the other.

The number a fleet manager needs is not the failure rate, it is the year the car starts costing more. Between age 6 and 7 the failure rate of this model jumps by 7.66 percentage points — the steepest single step in its life, and the natural planning point for replacement.
Repair spend uses the same modal prices as the section above, so it inherits the same limits: one typical repair per component group, not a full remedy. Downtime is the gap between the failed test and the passed re-test, which is the window a vehicle is legally off the road.
Ford Fiesta rust problems: where they corrode
Age-standardised corrosion susceptibility stands out at 1.69×, against 1× for the national age-standardised rate.
above 1.0× = rusts more than averagebelow 1.0× = rusts less
This Ford Fiesta fails on corrosion far more often than average once age is held constant, and its owners live in areas that are about typical 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.
Does a Ford Fiesta advisory become a failure?
Lamps, reflectors and electrical equipment are highest at 25.3%; Identification of the vehicle is lowest at 3.4% — the gap is 21.9 percentage points.

| Identification of the vehicle | 3.4% | 12 months | 5,430 | 193,569 |
This is the question an advisory note actually raises, and it needs six years of test history to answer. We followed the same vehicles from one MOT to the next across 2019–2024 and measured how often a component that was merely advised came back as a genuine failure at the next test.
Read it as a budgeting horizon, not a prophecy: the most likely component above turns into a failure for about 25 in 100 cars, and the median gap is 12 months and roughly 5,268 miles. The rest were repaired, sold, scrapped, or simply held. Rows with fewer than 500 tracked advisories are not shown.
What will fail next on a Ford Fiesta?

The same chains, cut differently: given a car's age and how its last test went, which component most often causes trouble at the following one.
The pattern that repeats across every family: a failure at one test roughly doubles the chance of a failure on the same component at the next one, and an advisory sits about half-way between a clean pass and a failure. Age bands in years; probabilities are per car, not per defect item.
Ford Fiesta ownership: what six years of MOTs show
The same-day re-test pass rate is highest at 49.8%; The later re-test pass rate is lowest at 2.2% — the gap is 47.5 percentage points.
higher = larger sharecompare shares in percentage points
Failing is usually a same-week event, not a disaster. Of 1,994,925 failures followed through to their re-test, 49.78% were repaired and passed the same day and 47.98% within ten days; the median gap is 1 day. 5,069,793 defect items were cleared in the process.
Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.603 failures per 10,000 miles, on a median of 4,692 miles a year across 1,575,740 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.
Two populations hide inside one model. 33.37% of these cars strung together three or more tests with nothing recorded at all, while 34.73% carried the same advisory three times or more — the same fault, noted, ignored, noted again. When you buy used you are buying one of those two histories, and the MOT record shows which.
Odometer anomalies: 0.847% of 1,576,465 chains show a reading lower than the previous test, with a median drop of 16,392 miles. We call this an anomaly and not fraud on purpose — instrument swaps, imports, unit mix-ups and keying errors all land in the same bucket. Obvious typos (drops under 100 miles or over 90% of the reading) are already excluded.
Do Ford Fiesta recalls reduce MOT failures?
R/2021/348 (Lamps, reflectors and electrical equipment) beyond the comparison fleet stands out at +1.1 pp, against 0 pp for no movement beyond the fleet.

A fair test needs a control. Failure rates climb as any fleet ages, so a simple before-and-after around a recall date makes every campaign look useless. Below, each campaign's component is age-standardised and compared against how every other model published here moved on that same component over the same months. The last column is what is left after subtracting the fleet-wide drift.
Negative in the last column means the recalled component improved faster than the rest of the fleet. Across all campaigns we could measure, roughly half clear that bar and half do not — recalls help, but the effect is small at fleet level and inconsistent between campaigns. not causal: no VIN-level link between a car and a campaign, and no evidence the remedy was carried out. Cells with fewer than 500 tests either side are not published. One limit decides how far this goes: the MOT inspects brakes, lights, suspension and structure, so a recall for an airbag inflator or a wiring fire risk leaves no trace here at all. Read this as evidence about recalls whose component the test actually examines — never as a verdict on whether recalls work.

DVSA lists 32 safety recall campaigns for the Ford Fiesta — 0.26 campaigns per 10,000 of these cars licensed in Great Britain, covering roughly 77,427 vehicles in total. A recall is the manufacturer fixing a fault for free, so an open recall on your car costs nothing to clear.
Counter-intuitive, and measured on our own data: across the 25 families published here, more recalls go with a lower MOT Risk Index (r = −0.52). Heavily recalled models are not worse cars in the test bay — an active manufacturer removes the fault before it becomes an MOT failure.

Ford Fiesta technical service bulletins: what dealers are told
NHTSA manufacturer communications are 172.
bigger number = more recorded dealer communicationsnot affected vehicles or confirmed faults
These are the issues the manufacturer fixes quietly: service communications sent to dealers without a public recall campaign. They show what the service network has been told even when the issue never became news.

Caveat worth stating plainly: this is NHTSA data about US-specification cars. British cars sold under the same name often use different gearboxes, engines and equipment, so a bulletin may describe a component that was never fitted here. The file counts dealer communications, not affected vehicles or confirmed failures, and it cannot tell you whether an individual UK car has the issue. A communication can carry more than one subject tag, so topic counts do not have to add up to the total.

Ford Fiesta owner complaints: what goes wrong
Transmission (not MOT-tested) is highest at 258; Body & structure are lowest at 23 — the gap is 235.
bigger number = more recorded casescompare like-for-like scope, not sample size alone
| Component | Complaints | Share | MOT fail items per 100 | MOT rank | Agreement |
|---|---|---|---|---|---|
| Transmission (not MOT-tested) | 258 | 40.6% | not in top 6 | — | complained about, rarely an MOT failure |
| Engine (not MOT-tested) | 147 | 23.1% | not in top 6 | — | complained about, rarely an MOT failure |
| Lamps & electrical | 70 | 11.0% | 29.9 | #1 | complained about and fails often |

| Brakes | 27 | 4.2% | 12.9 | #4 | complained about, fails occasionally |
| Body & structure | 23 | 3.6% | 7.3 | #6 | complained about, fails occasionally |
Two different populations answering two different questions: the MOT records what an inspector can measure once a year, the complaint file records what annoyed or frightened an owner on the road. A component high in one column and absent from the other is the interesting case — driver-assistance and electronics dominate complaints while almost never appearing as an MOT failure item.
What the reports actually say
The back up camera quit working. The back seats are taller and it has made it very difficult to see if there are children behind my vehicle. I reported it to the dealership and now I have to pay $200.00 to have them check it.
Purchased vehicle at the end of 2018 and this is the third time I have had to replace the horn. It's not a fuse, it's not wiring, it is the actual horn that either shorts or dies with no notice.
US owners have filed 636 complaints about the equivalent Ford Fiesta to the National Highway Traffic Safety Administration, including 50 that mention a crash, 3 a fire and 55 an injury. These are owner reports, not verified findings — but they are the only large public record of what drivers themselves notice, and they cover the years between MOT tests.
Caveat worth stating plainly: US-specification cars, self-selected reporters, no denominator — complaint counts scale with how many cars were sold there and how motivated owners are to file. The mechanical gap matters as much as the statistical one: American cars of the same name often carry different gearboxes, engines and equipment — automatics where Britain buys manuals — so a drivetrain complaint filed in Ohio may describe a part that was never fitted here. Read the ranking inside a model, not between models, and treat drivetrain entries with particular caution.

Ford Fiesta inspection results in other countries
United Kingdom MOT stands out at 34.3%, against 26.0% nationally.
higher = larger sharecompare shares in percentage points
| Country | Test | This model fails | National average | Position | Sample |
|---|---|---|---|---|---|
| United Kingdom | MOT (class 4) | 34.33% | 26.01% | +8.3 pp | 1,959,383 |
| Netherlands | APK | 51.6% | 50.9% | +0.7 pp | 119,462 |
| Finland | Katsastus | 27.1% | 26.3% | +0.8 pp | 22,437 |
| Norway | PKK | 38.1% | 33.5% | +4.6 pp | 3,779 |
The verdict is consistent across every regime we can measure, which is the strongest form this comparison takes: independent inspectorates, different rulebooks, same direction of travel.
| Fault area | Share |
|---|---|
| Axles, wheels and suspension | 48.2% |
| Steering equipment | 21.8% |
| Brake systems | 14.3% |
| Environmental hazards | 7.5% |
| Chassis and body | 3.8% |
Useful as a cross-check on the UK defect table above: the categories are named differently, but a component that dominates in both regimes is a genuine weak point of the model rather than an artefact of one country's testing style.
| Code | Fault | Recorded | Type |
|---|---|---|---|
210 | Tyre pressure not at the correct value | 21,530 | failure |
205 | Tyre with insufficient tread | 15,646 | failure |
516 | Dipped headlight incorrectly aimed | 10,116 | failure |
AC1 | Tyre down to 1.6–2.5 mm of tread | 8,124 | advisory |
203 | Tyre damaged | 7,143 | failure |
391 | Wipers leave insufficient visibility | 5,727 | failure |
576 | Indicator colour wrong or not permitted | 5,685 | failure |
497 | Number-plate light not working or missing | 5,391 | failure |
Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 1.234 defects per inspection against a much higher national failure rate than Britain's, and the reason is not that Dutch cars are worse — it is that the two regimes draw the line between "note it" and "fail it" in different places. Codes are the RDW's own; the English wording here is our translation of the Dutch original.
Britain is not the only country that inspects every car every year, and the Ford Fiesta is on the road in all of them. Each national regime writes its own rules, so the pass rates below are not comparable to each other — what does travel across a border is whether a model sits above or below its own country's average.

Ford Fiesta MOT: quick answers
Ford Fiesta MOT Risk Index stands out at 117.8, against 100 for a car with the same age profile.
below 100 is betterabove 100 is worse100 = normal for this model at that age
- What is the Ford Fiesta first-time MOT pass rate?
- 65.67% of first attempts passed in 2024 (1,959,383 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 34.33% figure is the first-time initial failure rate, using 1,959,383 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 117.8 is shown separately because raw rates compare fleet age as well as cars.

Data details & how to cite
Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap.
