South Korea marque
Kia in the UK
Kia arrived in Britain in the early 1990s and its seven year warranty, introduced in 2010, did more than anything else to move it into the mainstream. The Sportage has been the second best selling new car in the country for three years, so it is becoming as common used as the Qashqai. The Picanto plays the same role at the other end of the market, and both share engineering with Hyundai.
There is no reliability figure for Kia 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 Kia 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 Kia record does and does not settle
There are 6 Kia model lines here and the oldest of them went on sale in Britain in 1995. Of those, 5 are still sold new and 1 has 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. The sales period is missing for 1 of them, and that page says as much rather than printing a range we cannot cite.
Between them those models have been sold here with 6 different fuel types: petrol, diesel, petrol mild hybrid, plug-in hybrid, petrol hybrid 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. The alternative fuel discount that used to shave a little off hybrids ended on the same date, so hybrid badging no longer changes the bill. 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 3 ways: hatchback, estate and SUV. 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 1995, 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 Kia 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.
