According to Which? their latest car survey results prove that buying a quality car doesn’t mean ‘you get what you pay for’. The results of the 2020 car reliability survey show the two least reliable brands. 

Tens of thousands of car owners tell Which? about their ownership experiences over the past year, and for some luxury brands, the results are poor.

Out of 35 car brands, based on their survey (between December 2019 and February 2020) of 47,013 car owners and their 55,833 cars, Which? Reveal the two least reliable brands.

Reliability ratings are divided into two groups: cars up to three years (often covered by warranty), and cars three to eight years old in order to look at both early and later life reliability. These reliability ratings are given to brands as well as individual car models. 

Which? unreliable car brands pLand Rover was one of the two least reliable brands according to Which? and the only manufacturer out of the 35 in our survey to get one star out of five for both 0-3 and 3-8-year brand reliability. In this survey, 92 % of diesel Land Rover owners describe faults with the emissions/exhaust system. Owners also have issue with the car’s on-board computer software and Which? Consider this a common issue across most of Land Rover’s SUVs. The two Land Rover models in particular that seem adversely prone to this issue are the current Range Rover Sport (2013-) and the Range Rover Velar (2017-).

The other brand to be considered the least reliable in this survey was Tesla, which is the second-most commonly owned EV brand on their survey. The Tesla Model S saloon and Model X SUV both get the lowest score for 0-3-year reliability which boils down to high fault rates and long garage stays.
