The last-generation Range Rover has topped a list of the least reliable cars, according to Warrantywise.

Land Rovers, BMWs, and Porsches take up seven out of ten of the least reliable models from the Reliability Index data range.

The data only includes cars that are less than 10 years old, outside of the manufacturer’s warranty, and discounts models with less than 100 plans, to ensure a fair sample size.

Scoring as the most unreliable, according to the reliability index, the Range Rover rated lowest due to the frequency and cost of repairs.

With the highest repair costs being £23,890, and the frequency of repairs impacting the general reliability, the marque’s previous generation Range Rover obtained an overall score of 20.2/100.

Though 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 10 models.

Land Rover takes up two of the bottom three positions, with its previous generation Range Rover, and the Range Rover Sport coming in at first and third least reliable, respectively.

Both these models have since been replaced with all new versions and will soon be available with electric powertrains.

Last year, the brand was also found to produce the least reliable models in a study by What Car?.

Lawrence Whittaker, CEO of Warrantywise, 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.

“Our sole purpose here at Warrantywise is to ensure that no matter what car you buy, it’s covered and taken care of. Since the rise in parts cost and labour since last year and continued pressures on the rising cost of living, it’s even more important to protect your investment and learn about which cars to buy used, too. Through the Reliability Index, we are able to steer customers the right way when it comes to investing in a car. However, no matter what car it is – and how reliable it is – we can support it.”
