Most and least reliable car brands 2018
We asked you about the reliability of your cars, and more than 18,000 people responded. Here we reveal the most – and least – dependable brands, based on data for cars aged one to four years old...
To find out who builds the most – and least – dependable cars, What Car? asked drivers if they had experienced any faults in the past 12 months.
More than 18,000 people responded, allowing us to compile ratings for 159 models from 31 different brands, with the best performers having no faults at all and the worst suffering a 50% failure rate.
We then filtered these results to focus on cars aged one to four years old, before giving each brand a reliability rating which factored in cost of repair and time off the road.
So, whose cars are most likely to let you enjoy trouble-free motoring and whose could well leave you stranded by the side of the road or facing a hefty repair bill?
