Kia Cerato — MOT statistics 2024
The Kia Cerato failed 50.81% of 744 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 117.7 (100 = expected for its age profile). This car fails its MOT about 18% more often than expected for its age. Small sample — treat with care.
Age-adjusted peer: Fiat Multipla (index 117.6) — the two published results are 0.1 index points apart.
Kia Cerato common problems: what actually fails the MOT
Brakes stand out at 55.9 per 100 tests, against 22.1 per 100 tests across UK vehicles of the same ages.

family vs national — matched to UK 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.
Component-group comparison table
Each ratio carries a 95% interval. With 6 groups compared here, roughly one apparent difference in twenty is chance alone, and 1 of these is already inside an interval that includes 1.00×.

If a car like this fails, does it fail again?
A failure rate does not say whether a failure is a one-off or the start of something. This follows the same vehicles into their next ordinary MOT a year later — retests after a repair are excluded, because they follow a failure by definition. 2019-2024.
| After this year's test | Fails next year | Vehicles followed |
|---|---|---|
| It failed | 45.7% | 783 |
| It passed | 42.4% | 3,279 |
A failed test does not clearly change next year's odds here (45.7% against 42.4%): the difference is within the margin of error. The failure most likely to come back is noise, emissions and leaks — 43.9% of those vehicles fail again next year. Some of this is the vehicle and some is the owner: a car that was let go once tends to be let go again. One caveat: a car that fails may be sold or scrapped rather than tested again, so these figures describe the vehicles that came back.
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 9,691 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.
| Standardised for | Index | Reading |
|---|---|---|
| Age only | 116.0 | fails more often than expected |
| Age and annual mileage | 120.6 | fails more often than vehicles driven as much |
| Share doing under 3,000 miles a year | 11.1% | a normal spread of use |
Mileage matters here: matching on how much these are driven moves the figure by 4.6 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 Kia Cerato 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.
| Age | Kia Cerato | Same class, same age | Difference | Tests |

| 19 years | 50.92% | 47.74% | +3.18 pp | 436 |
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.

Is a Kia Cerato ULEZ compliant?
The share of classifiable 2024 Kia Cerato MOT tests likely ULEZ compliant by first-registration date is 36.9%.
Based on 743 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 | 46.69% | 29.33% | +17.4 pp |
Takeaway: the spread between best and worst month is 7.7 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 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.
Kia Cerato average mileage by age
At age 19, the middle half of Ceratos runs from 58,018 miles to 106,639 miles, against 80,463 miles as the median.

Does high mileage mean more Kia Cerato MOT failures at the same age?
Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 15+, 45.5% of those with 40,000–70,000 miles failed first time versus 54.4% of those with over 140,000 miles.No clear mileage gap inside this age group, among cars still being tested.

No engine band clearly fails less or more for its age: the bands are within 5 index points of each other, or their 95% intervals overlap, so this page does not name a best or worst engine.
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 100 tests are not shown; bands under 5,000 tests are rough estimates.
Kia Cerato MOT repair costs
The MOT-failure repair budget per test runs from £228.07 to £433.33, 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 |
|---|---|---|---|---|
| Brakes | 55.9 (nat. 11.25) | Front brake pads (parts + labour, typical hatchback) | £150 | £83.85 |
| Suspension | 43.3 (nat. 15.36) | Suspension coil spring (single corner) | £180 | £77.94 |
| Lamps, reflectors and electrical equipment | 40.4 (nat. 18.09) | Battery replacement (standard 12V lead-acid) | £140 | £56.56 |
| Tyres | 10.8 (nat. 8.7) | Tyre (single mid-range 16" fitted) | £90 | £9.72 |
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 £228 to £433, 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.
Kia Cerato running costs for a fleet
Vehicles failing at age 19 are close to the reference at 51.0%, against 50.0% at age 18, tested in the same year.
higher = larger sharecompare shares in percentage points
Failure rate and typical odometer by age
| Age | Fails | Median odometer | Tests | Gap vs age 5 |
|---|---|---|---|---|
| 18 | 50% | 81,276 | 298 | — |
| 19 | 50.63% | 80,463 | 318 | — |
No single year stands out as the point where this model starts costing more: the year-to-year steps in its failure rate are too small or rest on too few tests to name one (D1 rule: a step is named only with at least 2,000 tests on both sides and a jump above 3 percentage points).
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.
Kia Cerato rust problems: where they corrode
Age-standardised corrosion susceptibility stands out at 6.16×, against 1.00× for the national age-standardised rate.
above 1.0× = rusts more than averagebelow 1.0× = rusts less
This Kia Cerato 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 Kia Cerato advisory become a failure?
Suspension is highest at 33.4%; Identification of the vehicle is lowest at 5.6% — the gap is 27.7 percentage points.
higher = more likelypercentage is the observed transition probability
chance the same component fails at the next MOT, given an advisory now
| Component | Fails next time | Typical lead time | Miles of warning | Advisories tracked |
|---|---|---|---|---|
| Suspension | 33.4% | 12.1 months | 4,124 | 1,567 |
| Brakes | 29.6% | 12.1 months | 4,050 | 2,918 |
| Body, chassis, structure | 17.2% | 12.1 months | 4,448 | 552 |
| Tyres | 11.7% | 12.2 months | 4,119 | 1,797 |
| Identification of the vehicle | 5.6% | 12 months | 4,818 | 550 |
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 33 in 100 cars, and the median gap is 12.1 months and roughly 4,124 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 Kia Cerato?
Lamps, reflectors and electrical equipment after a failure at age 15-19 are highest at 34.7%; Brakes after a passed at age 15-19 are lowest at 14.1% — the gap is 20.7 percentage points.
higher = more likelypercentage is the observed transition probability
| Age | Last test | Most likely next failures | Cars tracked |
|---|---|---|---|
| 12-14 | passed | Brakes 18.0% · Suspension 17.8% · Lamps, reflectors and electrical equipment 15.6% | 774 |
| 12-14 | advisory | Suspension 25.7% · Brakes 23.5% · Lamps, reflectors and electrical equipment 22.0% | 1,109 |
| 12-14 | failure | Brakes 31.5% · Lamps, reflectors and electrical equipment 29.3% · Suspension 28.5% | 1,688 |
| 15-19 | passed | Suspension 17.3% · Lamps, reflectors and electrical equipment 15.3% · Brakes 14.1% | 632 |
| 15-19 | advisory | Lamps, reflectors and electrical equipment 27.0% · Suspension 24.4% · Brakes 23.5% | 1,028 |
| 15-19 | failure | Lamps, reflectors and electrical equipment 34.7% · Brakes 29.7% · Suspension 29.0% | 1,555 |
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.
Kia Cerato ownership: what six years of MOTs show
The ten-day re-test pass rate is highest at 69.4%; The later re-test pass rate is lowest at 4.6% — the gap is 64.8 percentage points.
higher = larger sharecompare shares in percentage points
Failing is usually a same-week event, not a disaster. Of 3,420 failures followed through to their re-test, 26.08% were repaired and passed the same day and 69.36% within ten days; the median gap is 2 days. 11,768 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 1.089 failures per 10,000 miles, on a median of 3,543 miles a year across 2,203 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. 14.73% of these cars strung together three or more tests with nothing recorded at all, while 51.29% 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: 0.726% of 2,204 chains show a reading lower than the previous test, with a median drop of 10,104 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.
Kia Cerato inspection results in other countries
United Kingdom MOT stands out at 50.8%, 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) | 50.81% | 26.01% | +24.8 pp | 744 |
| Finland | Katsastus | 42.5% | 26.3% | +16.2 pp | 4,201 |
| Netherlands | APK | 61.6% | 50.8% | +10.8 pp | 1,080 |
The verdict is consistent across every regime where the difference is clear, which is the strongest form this comparison takes: independent inspectorates, different rulebooks, same direction of travel.
| Fault area | Share |
|---|---|
| Brake systems | 40.1% |
| Chassis and body | 19.2% |
| Axles, wheels and suspension | 18.4% |
| Environmental hazards | 14.3% |
| Steering equipment | 4% |
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 | 227 | failure |
205 | Tyre with insufficient tread | 141 | failure |
497 | Number-plate light not working or missing | 114 | failure |
516 | Dipped headlight incorrectly aimed | 89 | failure |
AC1 | Tyre down to 1.6–2.5 mm of tread | 81 | advisory |
584 | Sidelight not working properly | 78 | failure |
289 | Schijf-, trommelrem loopt niet vrij | 72 | failure |
203 | Tyre damaged | 60 | failure |
Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 1.66 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 Kia Cerato 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.

Kia Cerato MOT: quick answers
Kia Cerato MOT Risk Index stands out at 117.7, 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 Kia Cerato first-time MOT pass rate?
- 49.19% of first attempts passed in 2024 (744 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 50.81% figure is the first-time initial failure rate, using 744 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 117.7 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.
