Range Rover named the most unreliable used motor in Britain


The Range Rover has been named the most unreliable motor in Britain, according to research from one of the nation’s leading used-car warranty providers.

The previous-generation luxury SUV took the unwanted top spot in Warrantywise’s annual Reliability Index, which has been exclusively revealed to This is Money.

It scored a lowly 20.2 out of 100 points. The highest repair cost recorded in 2021 to 2022 was £23,890 – more than the price of a new Ford Focus. 

Premium-car problems: Land Rover’s Range Rover might be a luxury SUV but its not without its issues, having been named the least reliable used motor in Britain

Warrantywise’s reliability league table makes for difficult reading for some premium car brands. 

It has Land Rovers, BMWs, and Porsches taking up seven out of ten spots for the worst performers, proving that spending big on cars doesn’t guarantee issue-free motoring.

The data only covers used cars that are outside of the manufacturer’s warranty but are also less than ten years old.

The Range Rover Sport didn't fair much better than its bigger sibling. The sportier 4X4 - which has been on sale since 2013 - took third spot a score of 23.1 out of 100

The Porsche Panamera isn't a cheap car, and nor are some of the repair bills for examples outside of the manufacturer's warranty. One in the last year came to almost £11k

For specific models to be included, there needs to be records for at least 100 examples to be included in the index, which Warrantywise says is ‘based on precise and quantifiable data’.

Land Rover’s Range Rover took the unwanted number one spot for most unreliable mostly due to the frequency and cost of repairs with the opulent SUV. 

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 out of a score of 100.

Warrantywise says the average repair cost for an owner of the previous Range Rover model is £1,607, which it says is comparatively low against some of the other expensive vehicles that made to bottom ten.

Compounding the misery for the British car brand is the luxury SUV’s sister model, the Range Rover Sport.

The first two generations of the sportier 4X4 – which has been on sale since 2013 – took third spot in the list of unreliable used motors to own with a score of 23.1 per cent.

Like its bigger sibling, the highest repair cost seen in 2021-2022 was enough to buy a family-size hatchback, ringing in at £22,358.

BMW makes three appearances in the list of ten not-so-dependable models.

The M3 performance car took second spot, which covers both the previous-generation six-cylinder model (2014 to 2019) and the last of the V8-powered saloons, which were produced from 2007 to 2013, receiving a reliability score of 21.4 per cent and recording a highest repair bill of £12,115.

The German brand’s previous-gen X6 took fifth spot with a score of 23.6 per cent, while the M5 – based on the previous two derivatives of the potent executive model – rated tenth with a 30.8 per cent score.

Other flash motors making up the order were the Porsche Panamera and Cayenne, Audi’s Q7 SUV and the Bentley Continental GT.

The only ‘mainstream’ car making the bottom ten list was Mazda’s CX-5.

Both the current and previous generation of the family SUV placed in ninth with a lowly score of 29.6 out of 100, with the biggest repair receipt in 2021-2022 coming in at £5,777.

Lawrence Whittaker, boss 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.’
