·2-min read

The most and least reliable cars on sale in Britain have been revealed following a survey of more than 16,000 drivers.

Looking at nearly new cars and those up to five years old, the Reliability Survey is run by consumer publication What Car?, and provides scores for 178 vehicles from 30 manufacturers.

An impressive six models achieved a full 100 per cent rating. These were the current-generation Audi TT, Mazda CX-3, Mini Convertible and Mitsubishi Eclipse Cross, and the previous-generation Dacia Sandero and Honda HR-V.

Overall, Lexus was deemed the most reliable manufacturer, with an overall rating of 98.7 and none of its vehicles scoring less than 98.4. This was followed by Romanian firm Dacia, which scored 97.3 and Japanese manufacturer Suzuki, which achieved 97.1.

At the other end of the scale, Land Rover and Fiat achieved the lowest scores of 82 and 82.5 per cent respectively.

Luxury SUVs achieved the lowest score as a group with an average of 88.8. The Porsche Macan bucked this trend with a 97.9 per cent rating, while the Land Rover Discovery had the lowest rating of 72.1.

Looking at individual sectors, the BMW 1 Series was the highest-rated family car with 97.7 per cent, the Nissan Leaf was the most reliable electric car with 98.6, and the Skoda Superb was the best executive model with 99.2.

What Car? editor Steve Huntingford said: “The UK’s used car market is currently booming, making it all the more important that people know which models will be reliable. With feedback from more than 16,000 owners, the latest What Car? Reliability Survey highlights the brands and models with the best and worst records.

“Our latest study also shows that a high price tag isn’t always a guarantee of reliability, because some of Britain’s cheapest cars are among the most reliable.”

The 16,328 car owners were asked whether their car had gone wrong in the past 12 months, how long repairs took and how much they cost, with the overall score expressed as a percentage. Twenty per cent had experienced a fault with 85 per cent repaired for free.
