Is the Citroen C4 Cactus reliable?

On MOT evidence the Citroen C4 Cactus is below average. It passes 69.0% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 62% of the national age and mileage range, which is enough to quote but not to rank. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What is the most common MOT failure on a Citroen C4 Cactus?

The item recorded most often is "Wiper blade missing or obviously not clearing the windscreen", which appears in 20.6% of failed Citroen C4 Cactus tests. Because one failed test can list several items, these shares do not add up to 100%.

What do testers most often warn about on a Citroen C4 Cactus?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 24.1% of all Citroen C4 Cactus tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Citroen C4 Cactus usually have at its MOT?

The average odometer reading recorded at test is 52,882 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Which Citroen C4 Cactus years are the most reliable?

Going by MOT pass rate, Citroen C4 Cactus cars first registered 2020–2022 do best at 81.9%, and those registered 2014–2016 do worst at 61.7%. But that ordering is mostly age, not build year: almost every model passes less often as it wears, so the newest cars top this list whatever they are. A specific year looking strong here means little on its own; the failure items above, and the individual car's own MOT history, tell you far more.

Does a Citroen C4 Cactus get harder to pass as it ages?

Yes. At 3 to 5 years old, 81.9% of Citroen C4 Cactus tests pass. By 9 to 11 years, that falls to 61.7%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Citroen C4 Cactus models petrol or diesel?

Of the Citroen C4 Cactus cars tested, 74% are petrol, 26% are diesel. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Citroen C4 Cactus common problems, by part and by year

The same failure record read the way a buyer asks the question: which parts wear out on a C4 Cactus, when they start, and how each registration year compares — including the steps that mark a generation change.

How wear changes the picture

C4 Cactus pass rate by age and registration year

How often the Citroen C4 Cactus passes at each age, with the years those cars were first registered. Tests are from 2025, so a car aged 3 to 5 was first used in 2020–2022.

3–5 yrsreg. 2020–202282%

6–8 yrsreg. 2017–201970%

9–11 yrsreg. 2014–201662%

Read this as an age curve rather than a verdict on particular model years. Nearly every car passes less often as it gets older, so a newer C4 Cactus outscoring an older one says more about wear than about how that year’s cars were built. Bands holding too few tests to be meaningful are omitted rather than shown as a rate.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
