The 10 Most Reliable Cars

| In Buying Guides

Motoring magazine What Car? has released their annual Reliability Survey. The survey asks approximately 22,000 owners of cars up to five years old if their vehicles encountered any issues within the last 24 months, and if so, what type of fault it was, how long the car was off the road and how much the repair bill was. This gives each vehicle a scoring percentage; the closer to 100%, the better the reliability.

We have compiled a rundown of the top 10.

How Is The Data Calculated? 

The What Car? Reliability Survey gathers insights from UK car owners. It focuses on vehicle faults experienced over the past 24 months, covering aspects such as the nature of the fault, repair costs, and time spent in the workshop. This approach allows for the creation of a unique reliability rating for each model and brand, emphasising the impact of these faults in terms of inconvenience and expense rather than just their frequency.

This year's survey includes data from 178 models up to five years old across 32 brands. In its detailed analysis of car reliability, the survey differentiates between petrol, diesel, and hybrid versions of each model, provided there is enough data. This distinction helps in offering a more comprehensive understanding of each vehicle's reliability.

The 2016-2022 Hyundai Ioniq Hybrid stands out in the family car category with a low fault rate of 3%. The main issues were with bodywork and sat-nav/infotainment, but most cars were back on the road in a day or less, with costs covered by Hyundai. The Hyundai Ioniq Hybrid scored 99.2% in the survey 

9. BMW iX3
