France marque
Citroën in the UK
Citroën built cars at Slough from 1926 until 1966 and has sold here continuously since. It now sits in Stellantis next to Peugeot and Vauxhall, sharing platforms and engines with both. Its used presence is concentrated in the C1, C3 and the C4 Picasso people carriers, and the C1 shares its whole structure with the Peugeot 108 and Toyota Aygo built alongside it in Kolín.
There is no reliability figure for Citroën as a marque that this site could cite. What circulates instead is survey data from panels that select themselves, warranty claim rates published by companies with a product to sell, and averages built by choosing which years and variants to count.
Each of those choices moves the answer by several percentage points, and none of them is a measurement a reader could go and check. A number printed beside the Citroën badge here would be our arithmetic wearing somebody else's name.
What is genuinely knowable is one car at a time: its own invoices, its own service record and what the common repairs on that model actually cost when they arrive.

Before you buy one
What the Citroën record does and does not settle
There are 6 Citroën model lines here and the oldest of them went on sale in Britain in 1996. Of those, 4 are still sold new and 2 have finished. A finished line is not automatically a worse buy, but it fixes the newest example you will ever find and it decides how long the parts supply has had to run.
Between them those models have been sold here with 3 different fuel types: petrol, diesel and electric. That spread is the practical reason one figure for the whole marque would be no use to anybody standing on a forecourt. Electric cars lost their road tax exemption on 1 April 2025, so an electric one now pays the same standard rate as a petrol one of the same age. Diesels carry a particulate filter, and a car used only for short cold journeys will keep blocking it until the driving pattern changes.
Those lines were bodied 4 ways: hatchback, SUV, MPV and van. The MPVs carry a second and sometimes third row of belts, and every belt, buckle and mounting is a wear item. Van bodied versions are taxed as light goods vehicles at a flat rate rather than by CO2, so the car and the van of one model do not cost the same to keep taxed. The four wheel drive versions carry more driveline than the two wheel drive ones, and driveshaft boots and propshaft joints are all inspected.
Because the oldest line here reaches back to 1996, examples across this marque fall under all three road tax regimes: engine size for anything first registered before 1 March 2001, CO2 bands from then until 31 March 2017, and the flat standard rate for anything registered on or after 1 April 2017. That is why the tax figure on each model page names the year and the engine it applies to, and why it is safer to read the V5C than to take a rate from a badge.
What goes wrong on a Citroën is decided by the individual car and the person who owned it last, not by the marque. Two examples of the same model and year, one serviced on time and one not, are in completely different condition, which is the honest reason a marque average would mislead you even if somebody published one. The invoices for the car in front of you name what was actually replaced, when, and at what mileage. Read those instead.
