The previous-generation Mazda 6 isn’t a particularly robust choice among executive cars. Just over a third of cars suffered a fault, with the brake system, engine electrics and steering the biggest concerns. All cars were put right in less than a week and 42% of them in a day or less, but a third of owners were landed with bills of between £501 and £1500.

Nearly a third of cars couldn’t be driven and nearly half spent up to a week in the garage. Owners faced a wide range of repair costs, from less than £50 up to £1500.
