The UK’s top ten least reliable cars that will rack up your repair bills

The UK’s top ten least reliable cars have been revealed – with some surprising results.

The list is not dominated by cheap old bangers, but instead by luxury vehicles .

Warrantywise, an extended car warranty provider, has revealed Land Rovers, BMWs, and Porsches make up seven out of ten of the least reliable models.

The Reliability Index research found not only can luxury cars be more likely to break down, they also cost a fortune to repair when they do.

To come up with the list, Warrantywise looked at cars that are less than ten years old and outside of manufacturer’s warranty.

Jaguar Land Rover’s Range Rover tops the list as the UK’s most unreliable used car.

One saving grace for the Range Rover was that the average repair cost (cost recorded in 2021) for the model is £1,607 – an amount that is actually quite low compared to many of the other bottom ten models.

Warrantywise chief executive Lawrence Whittaker said: “The Reliability Index is extremely revealing of how luxury cars, which may seem like they would be reliable because of the costly price tags, aren’t always so.

“The opinion that they should be very reliable, for the price that customers pay for them, is quite a popular one, and this evaluation of our data is helpful for us to guide customers the right way when wanting to make a large purchase on a luxury car, like a Porsche.”

The list of the top ten least reliable cars according to Warrantywise, is below.

Self-driving vehicles could be running on motorways in the next year , the Government has revealed.

Drivers will still need to have a licence so they can take over on other roads.

But by 2025 the aim is for autonomous buses and delivery vehicles to run without the need for a driver.

Transport Secretary Grant Shapps said the vehicles would make roads safer, create up to 38,000 jobs and be worth £42 billion. The Government is spending £100million to promote the scheme.

Mr Shapps added: “The benefits have huge potential – improved access to education and other services and the creation of tens of thousands of jobs.”
