New research has revealed the most reliable and unreliable vehicles on the road across the country, with an impressive four cars all scoring a perfect 100 per cent rating.
New rankings from What Car? have revealed that the Hyundai i10, Hyundai Santa Fe, Kia EV3 and Toyota GR Yaris all achieved a perfect reliability ranking.
The ratings were handed out based on the experiences of 32,493 owners over the last two years, with respondents detailing the number and nature of any faults, how much they cost to fix and how long the cars were off the road for.
The data found that 95 per cent of cars which needed to be repaired were fixed for free, up from 82 per cent last year. Despite this, 1.4 per cent of owners were left with cars of more than £1,500 per fault.
The What Car? Reliability Index found that the four vehicles tied for first did not have any common faults, had no repair costs and did not spend any time off the road.
The Toyota Aygo X, which achieved a very respectable score of 99.7 per cent, only had a few faults, with three per cent of owners noting bodywork repairs. However, these were free and only took a few hours to repair.
Honda was ranked as the most reliable car brand, scoring an impressive 96.6 per cent, with drivers highlighting the Jazz, HR-V and Civic models for low fault rates and repair costs.
Rebecca Adamson, head of automobile at Honda Motor Europe (UK), said it was “an incredible achievement”. She added: “Reliability is a cornerstone of our brand, and this recognition reflects the trust our customers place in us. In 2025 and beyond, we remain committed to delivering vehicles that not only inspire but also stand the test of time.”
