Land Rover makes most unreliable cars, claims Honest John

  • Honest John website surveyed 6,000 users to find the most unreliable cars
  • Website found best and worst performing car manufacturers and used car models
  • Land Rover said to have worst record for reliability while Mercedes GLC is least satisfying to own

Time 7:10 am, January 6, 2023

Motoring website Honest John has named Land Rover as the most unreliable car manufacturer.

The website polled 6,000 car owners and asked them to rate their cars under a variety of categories to give the cars a score out of 10.

The Honest John Satisfaction Survey then ranked cars for their reliability and how satisfied they were with the ownership experience.


Land Rover was named the maker of the most unreliable cars, followed by Peugeot and Fiat.

The Mercedes GLC was named as the least satisfying car to own, followed by the Toyota Rav4 and Ford Fiesta.

The Mercedes was singled out for its ‘high repair costs’ while owners also lambasted the ‘poor fuel economy’ of the 2015-2022 model.


And when it came to the most unreliable used car models, the Mercedes GLC was also branded the worst. In second place was the Peugeot 3008 and in third was the Ford Kuga.

Honest John senior editor Dan Powell said: ‘Six thousand people took part in the latest Honest John Satisfaction Index and the results will help car buyers make the most informed decision about their next vehicle purchase.

‘The Honest John Satisfaction Index uncovers what matters most to car buyers in the UK, with car brands and vehicles assessed on reliability, build quality, fuel economy, repair costs and performance. 

‘Ride comfort, handling, ease of use, practicality and technology are also considered, as well as safety.’

At the other end of the spectrum, Lexus was named the most reliable car manufacturer and the most satisfying to own overall.

Meanwhile, the Hyundai Tucson was named as the most satisfying individual used model to own.

The Honest John survey follows research by What Car? in September last year that found the Land Rover Discovery was the most unreliable used car.


That survey quizzed 25,000 owners and found those that had a Discovery experienced problems with electrics, bodywork and batteries.
