Citroen C3 Aircross — MOT statistics 2024

The Citroen C3 Aircross failed 15.05% of 29,668 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 98.6 (100 = expected for its age profile). This car is too close to call — statistically indistinguishable from normal for its age.

Age-adjusted peer: Ford Mondeo (index 98.8) — the two published results are 0.2 index points apart.

Citroen C3 Aircross common problems: what actually fails the MOT

Visibility is well below the reference at 1.9 per 100 tests, against 5.0 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.

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

Citroen C3 Aircross MOT advisories: what gets flagged

Tyres are highest at 45.8 per 100 tests; Emissions & leaks are lowest at 0.8 per 100 tests — the gap is 45.0 per 100 tests.

Tyres, brakes and suspension: Citroen C3 Aircross 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.

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.

A failed test raises next year's chance of failing again by 4.9 percentage points. The failure most likely to come back is body, chassis, structure — 22.1% 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 87,928 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.

Mileage matters here: matching on how much these are driven moves the figure by 12.5 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 Citroen C3 Aircross 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 Citroen C3 Aircross perform as it gets older?

higher = larger sharecompare shares in percentage points

Chart scale: 10%–33%.

bars: Citroen C3 Aircross · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 2.2 percentage points — booking month barely matters for this family. 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.

Citroen C3 Aircross average mileage by age

At age 5, the middle half of C3 Aircross models runs from 22,145 miles to 41,870 miles, against 31,544 miles as the median.

Does high mileage mean more Citroen C3 Aircross MOT failures at the same age?

Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 3–5, 11.1% of those with under 40,000 miles failed first time versus 24.3% of those with 70,000–100,000 miles.Inside this age group, higher mileage goes with more failures.

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

A typical 5-year-old C3 Aircross has ~31,544 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

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 frost days this model fails 2.8 pp more often than in the lowest fifth (r=0.51, n=46 areas with ≥800 tests).

In areas with the highest road-salt proxy this model fails 3.1 pp more often than in the lowest fifth (r=0.49, n=46 areas with ≥800 tests).

In areas with the highest mot centre density this model fails 1.9 pp more often than in the lowest fifth (r=0.32, n=46 areas with ≥800 tests).

Values shown in the quintile chart

Frost days	10.7%	13.5%	+2.8 pp	r=0.51
Road-salt proxy	10.6%	13.7%	+3.1 pp	r=0.49
MOT centre density	9.8%	11.7%	+1.9 pp	r=0.32

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 area indicators, each tested against a defect rate we measure

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

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.

Citroen C3 Aircross survival: which cars are still on the road

By age 7 is well below the reference at 5.0%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

Chart axes: car age, years · survival vs ages 4–6 · scale 0–105%.

By age 7, only about 5% as many cars of this family present for MOT as at ages 4–6 (reference n≈18,579); survivors still fail at 21.1% vs 11.4% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many years is a Citroen C3 Aircross likely to last?

Bought at age 5 stands out at 1.1 years.

bigger number = longer remaining lifeyears on the observed survival curve

estimateObserved only until age 7. The curve does not run five years past the stated age with the share still tested under 50%, so no 'years left' number is given.

Citroen C3 Aircross faults that come together

Body & structure + Steering stand out at 14.46×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Body, chassis, structure» and «Steering» appear together 14.46× more often than chance (20 co-occurrences in the same test; 66 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).

Is low mileage better for a Citroen C3 Aircross?

Cars driven under 5,000 miles a year is well below the reference at 11.0%, against 22.1% for cars driven 8,000–12,000 miles a year.

higher = larger sharecompare shares in percentage points

At matched ages 5–14, cars averaging under 5k miles/year fail at 11.0% vs 22.1% for 8–12k miles/year — 11.1 pp lower (n_low=10,513, n_normal=6,842). 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.

Which Citroen C3 Aircross engine is best?

diesel 1.5–1.8 is highest at 118.1; petrol 1.0–1.2 is lowest at 98.4 — the gap is 19.7 points.

below 100 is betterabove 100 is worse100 = normal for this model at that age

Splitting this model by fuel alone hides the thing that actually differs. Within the same badge, the diesel 1.5–1.8 runs at 118.1 against this model's own age norm while the petrol 1.0–1.2 runs at 98.4 — a spread of 19.7 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 100 tests are not shown; bands under 5,000 tests are rough estimates.

Best year for a Citroen C3 Aircross, and the years to avoid

Build year 2020 is highest at 107.0; Build year 2017 is lowest at 96.8 — the gap is 10.2 points.

below 100 is betterabove 100 is worse100 = normal for this model at that age

build year vs the same model at the same age · 100 = as expected

The best build year here is 2018 and the weakest is 2020. 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 — 2 of 4 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.

Citroen C3 Aircross MOT repair costs

The MOT-failure repair budget per test runs from £17.52 to £33.29, against £54.85 for the test itself.

bigger number = costs morepounds per test, MOT-failing faults only

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 £18 to £33, 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.

Citroen C3 Aircross running costs for a fleet

Vehicles failing at age 7 stand out at 21.0%, against 14.0% at age 5, tested in the same year.

higher = larger sharecompare shares in percentage points

The number a fleet manager needs is not the failure rate, it is the year the car starts costing more. Between cars aged 5 and cars aged 6, both tested in 2024, the failure rate of this model is 5.19 percentage points higher — the steepest one-year step in this cross-section of different cars, and a 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.

Citroen C3 Aircross rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at 0.15×, against 1.00× for the national age-standardised rate.

above 1.0× = rusts more than averagebelow 1.0× = rusts less

This Citroen C3 Aircross fails on corrosion much less often than average once age is held constant, and its owners live in areas that are saltier than most for the models we publish. Both point the same way and reinforce each other: it resists corrosion even though its owners live in saltier areas than most.

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 Citroen C3 Aircross advisory become a failure?

Body, chassis, structure are highest at 14.5%; Non-component advisories are lowest at 0.0% — the gap is 14.5 percentage points.

higher = more likelypercentage is the observed transition probability

chance the same component fails at the next MOT, given an advisory now

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 15 in 100 cars, and the median gap is 12 months and roughly 7,032 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 Citroen C3 Aircross?

Body, chassis, structure after a failure at age 6-8 are highest at 13.7%; Body, chassis, structure after a passed at age <3 are lowest at 1.1% — the gap is 12.6 percentage points.

higher = more likelypercentage is the observed transition probability

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.

Citroen C3 Aircross ownership: what six years of MOTs show

The same-day re-test pass rate is highest at 55.4%; The later re-test pass rate is lowest at 1.4% — the gap is 54.0 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 8,465 failures followed through to their re-test, 55.44% were repaired and passed the same day and 43.14% within ten days; the median gap is 0 days. 14,487 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 0.227 failures per 10,000 miles, on a median of 5,688 miles a year across 24,688 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. 27.52% of these cars strung together three or more tests with nothing recorded at all, while 10.95% 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: 0.611% of 24,710 chains show a reading lower than the previous test, with a median drop of 8,426 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.

Citroen C3 Aircross safety recalls and how to check yours

DVSA recall campaigns stand out at 17.

bigger number = more recorded casescompare like-for-like scope, not sample size alone

recall campaigns launched per year

DVSA lists 17 safety recall campaigns for the Citroen C3 Aircross, covering roughly 60,158 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.

Citroen C3 Aircross inspection results in other countries

Netherlands APK is well below the reference at 30.8%, against 50.8% nationally.

higher = larger sharecompare shares in percentage points

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.

Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 0.721 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 Citroen C3 Aircross 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.

Citroen C3 Aircross MOT: quick answers

Citroen C3 Aircross MOT Risk Index is close to the reference at 98.6, 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 Citroen C3 Aircross first-time MOT pass rate?

84.95% of first attempts passed in 2024 (29,668 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 15.05% figure is the first-time initial failure rate, using 29,668 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 98.6 is shown separately because raw rates compare fleet age as well as cars.
