Most and least reliable car brands 2018
To find out who builds the most – and least – dependable cars, What Car? asked drivers if they had experienced any faults in the past 12 months.
More than 18,000 people responded, allowing us to compile ratings for 159 models from 31 different brands, with the best performers having no faults at all and the worst suffering a 50% failure rate.
We then filtered these results to focus on cars aged one to four years old, before giving each brand a reliability rating which factored in cost of repair and time off the road.
So, whose cars are most likely to let you enjoy trouble-free motoring and whose could well leave you stranded by the side of the road or facing a hefty repair bill?
Subaru owners are another group that tend to rate their car's dependability as one of the main reasons for choosing it – which is handy, because the brand's models very rarely cause trouble.
8. Alfa Romeo
The strong performance of Renault's Dacia budget brand shows that it's not how much you spend, but where you spend it, that matters when it comes to reliability.
Some Fiat models are also among the cheapest cars on the road, yet the Italian brand's score was still well above the average of 91.7%.
The previous generation Polo hatchback initially paints a bleak picture for Volkswagen, although the problem wasn't so much the number of issues reported, but that more than half of said issues rendered the car undriveable. In the MPV, class, however, the Golf SV claws things back with a far better score.
Despite its position towards the bottom end of our table, there is a silver lining for Renault; thanks to poor ratings for Peugeot and Citroën, it takes the accolade of being the most reliable French brand.
Tied with Audi for 20th position is Volvo. Its 2012-18 V60 was the most reliable executive car you, but elsewhere the Swedish brand doesn't perform so well.
Mini is some way behind its BMW parent when it comes to reliability, although at least none of its cars are in the bottom three of any class. That said, there are no Minis present in any of the top threes, either.
Porsche puts in the worst performance of any Volkswagen Group brand to be included in our survey. It's a tale of two cars, though, because while the 2012-2016 Cayman is among the worst performers when it comes to coupés, convertibles and sports cars, the current 911 is among the strongest.
The Peugeot 208 and 308 hatchbacks are both the least reliable cars in their class, with the old 3008 MPV also among the bottom three in its market. There are a couple of saving graces, however: the current 2008 and 3008 SUVs are among the top three performers in their respective classes.
While two Mercedes models, the B-Class MPV and the old E-Class saloon, come out at the top of their respective classes, plenty more cars with the three-pronged star fall towards the bottom: the C-Class saloon, Coupé and Cabriolet, the current E-Class saloon and the old A-Class diesel hatchback.
