The UK's most and least reliable used cars

A look at the most reliable motors on UK roads, plus those most likely to develop maintenance problems.
How dependable is your motor?
Are you constantly worrying that new warning lights will appear on your dashboard?
If so, you’re probably likely to become more concerned the older your motor gets.
To determine the brands most susceptible to problems, What Car? has collaborated with MotorEasy as part of its annual reliability study to identify the most reliable second-hand motors.
Car dashboard lights: what they mean and how much each repair will cost
How the test was conducted
Each car’s rating is determined by whether a driver would recommend the model to other users.
As well as brands, drivers gave feedback on specific makes and models.
Overall, 29,967 motorists were consulted, with data from 199 models across 31 brands.
While the researchers investigated performance over the past two years, eligible motors could be up to five years old.
Drivers gave information on faults and repair costs, with the researchers creating a “unique reliability rating for each car and brand'.
The most reliable brands
Mini racked up a near-perfect score of 98.3% across the five models covered in the research.
Looking at specific models, the brand had the most-praised SUV and electric vehicle, with its Countryman gathering 99.7% and the Mini Electric bagging 98.4%.
This was closely followed by Lexus at 97.9%.
Its ES model came top in the executive class, bagging 99.3%.
Likewise, its 2014 to 2021 NX was named the most reliable family SUV, with an exemplary 100%.
Taking third place, Suzuki has an overall rating of 97.7%, with its Swift and Vitara achieving 95.7% and 97.7%.
When it comes to particular models, the 2014 to 2021 Lexus NX and the 2021 Toyota Aygo X bagged perfect 100% scores.
New entrants
Interestingly, several new brands made their way into the top 10.
For instance, Dacia, Citroen and Renault took sixth, seventh and ninth place.
That said, Toyota fared less well, falling from second place in 2023.
As The Daily Mail points out, BMW was the sole German manufacturer to occuoy a place in the top 10.

The least reliable cars
At the other end of the spectrum, the more affordable MG attracted a score of 76.9%.
Next up, Alfa Romeo was the second least reliable.
In particular, Giulia and Stelvio drivers believed their motors had spent long periods awaiting repairs, with Gulia having high repair costs.
Vauxhall's Corsa Electric and Mokka Electric occupied the bottom three in their respective classes.
Note, German brands featured prominently in the bottom 10, with Audi as the eighth least reliable and Mercedes-Benz taking 10th place.

Bacchu5: Thanks for the personal attack. Two of us state warranty figures. Doesn't that tell you anything? Our comments were on an article where the figures came from a warranty company. Love money decide to reissue this report with a changed source of data, but kept the old comments. Perhaps if you read the reports here more regularly you would know that. Owning a German car or a small number will not increase an understanding of it's reliability. However, reading articles like this one, JD Power and Consumer.org etc, analyse far larger data sets and so the figures are more meaningful. Don't you understand how statistics work? For example, in a recent JD Power survey for the UK, BMW came bottom of the list for reliability. I know German cars are not worth their high cost thanks to reliability figures I find in these large surveys I mention. Oh, and I also check the monthly recall details that never never looks good for German cars. Do you? I once read a comment on the internet that stated 'German cars are a masterclass of image over quality'. I completely agree with the poster. Maybe if you were to check industry standard and respected organisations you would be better informed. I don't think your individual experience from ownership of reliability is relevant to the overall analyse. The organisations I have mentioned use huge datasets. I also read reports from other organisations/ magazines, etc, thereby covering data collected from large datasets. Maybe if you studied form better from the respected review companies, you would not make your ridiculous comments. Before anybody says it, JD Power and Consumer.org are American companies. But JD Power also release UK figures and the American market is huge so statistical data is more accurate, as many cars are now global.

I'm nor sure where the comments about the figures originating from a warrantee firm (nicknuts and photoping). The blurb states "The reliability survey from the experts at WhatCar? is a good place to start, as it is based on polling of car owners across the country, breaking down the most and least reliable motors in a host of categories, based on factors like how often they’d had to get their motor fixed in the previous 12 months, and the cost of putting things right should issues arise. Nicknut's comment about German cars is ridiculous if, as he says, he hasn't actually owned one. Mercedes may be a brand to avoid but plenty more were either 100% or getting close. Even the worst was at 75%. I bought 4 Japanese cars in a row and they were no more reliable or unreliable than any other car I've had, including 4 VWs.

I own a Toyota Arius. I've had it 3.5 years now. Its been faultless. However I wouldn't recommend it now to others. WHY? Because thieves have taken a real shine to the catalytic converters on these and similar hybrid models from Toyota. Have one stolen and its an insurance job to repair. Probably in excess of £1000 to repair. Current waiting time for a genuine replacement - about 8 weeks. Toyota say its not their fault and they offer a catlock and tilt sensor at a no profit rate. Cost £300. But do they warn new customers or existing owners of the potential threat to their vehicles or the consequences of the theft? what do you think? And customers are already out of pocket for a possible insurance excess and an increase in future premiums, all for buying a more environmentally friendly than other petrol or diesel cars. Toyota do little in reality to combat the thefts. The rate of theft has increased over time and they've done hardly anything practical to reduce the incidence of theft, to warn their customers or to press for increased police action and penalties for offender. Who regulates scrap metal merchants - its your local authority whose priorities of course lie elsewhere. Its entirely possible that the stolen cats are crushed and exported to a less well regulated country for recovery of the enclosed precious metals. But believe me its big business. And the thieves? they might get £150 for the cat and its precious metals inside. The task takes a skilled team 2 minutes and a slow team 3 minutes. Jack the car up at the side place a spare wheel under the front wheel in case the car slips from the jack, cut through exhaust pipe with battery powered saw, undo two bolt and they're done. remove cat, spare wheel, lower jack. Its so easy.
