Lexus is the UK’s most reliable car brand according to owners, with the Japanese luxury brand being named as the best car brand for reliability in the 2025 Honest John Satisfaction Index with a reader rating of 97.01%.
Each year HonestJohn.co.uk asks its readers to rate their car across a variety of important areas including efficiency, reliability, practicality and safety, as well as the its performance and comfort credentials. The result is the Honest John Satisfaction Index, based on the feedback from more than 6000 respondents.
Second place in the reliability rankings went the way of Tesla with an impressive score of 95.29% while Toyota – owners of the Lexus brand – cemented third place with a rating of 94.65%. With a score from our readers of 94.65% is Honda, with Skoda completing the best five with 93.08%.
Lexus’s NX model was also the most reliable car overall, ahead of the Skoda Karoq and Toyota Corolla.
At the other end of the 2025 Honest John Satisfaction Index, we see Alfa Romeo at the foot of the table (76.67%) ahead of Jeep (82.31%) and Vauxhall (84.53%), whose Corsa model was named the UK’s least reliable car.
One big surprise was that Mercedes was voted as the fifth worst brand for reliability on 86.03% – a huge disappointment given the price premium its models carry over rivals.
Meanwhile, it’s Tesla owners that were the most satisfied with the overall ownership of their cars at the time of the survey, with an 89.41% approval score.
Tesla’s popularity nudged Lexus into second place overall with an 86.32% overall satisfaction rating.
Securing third position for overall satisfaction with a score of 84.79% was Porsche, a result which narrowly edged Honda into fourth with 84.70%. Rounding-out the top five for overall brand satisfaction was Skoda on 84.51%.
Meanwhile, it was Alfa Romeo that picked up the wooden spoon with its 72.12% rating as the least satisfying brand to own overall.
That’s only slightly inferior to Fiat, a brand with which many mechanical and electronic parts are shared – Fiat scored 73.58%. At 76.11% is Vauxhall, but the British brand was only a solitary step above Fiat in this table.
Just above that threesome on 77.29% is MG, something the brand will be hoping improves as more people experience its newer, higher quality models.
But the Honest John Satisfaction Index 2025 covers more than just cars, with breakdown providers and insurers also evaluated. One of the lesser-known brands – GEM Motoring Assist – scored the top ranking for breakdown cover providers.
So impressed were Honest John readers with GEM Motoring Assist’s services that 87% indicated that they would renew their breakdown cover with the company, scoring an impressive overall satisfaction rating of 89.57%.
NFU Mutual was named the best car insurance company for the sixth year running.
With so much insurance choice available and customers shopping around as finances are stretched by inflated grocery and utilities costs, NFU Mutual is evidently delivering in terms its overall satisfaction index score of 87.48%.
