A total of 38 manufacturers and 50,000 cars, all of which were between three and eight years old, were accounted for in the survey.
Honda, which once again topped the rankings for the eighth consecutive year, was one of several Far Eastern brands in the top ten.
Those at the bottom of the table included Alfa Romeo, Porsche and Land Rover. Bentley came in last place, with 86 per cent of the Bentleys included in the survey expected to suffer a problem each year.
