3. BMW X6 (2014-2019)

Score 88.2%

Just over 31% of X6s went wrong, with gearbox issues being the most common complaint, accounting for 19% of faults. Other problematic areas included the exhaust, infotainment, interior trim and non-engine electrics.

All of the troubled cars could still be driven, but one in five took more than a week to repair. Three-quarters of work was done for free, but owners who had to pay were faced with bills ranging from £50 to £750.

Owners told us that 34% of their X-Trails had suffered a fault, with the main areas of concern being engine and non-engine electrics. Other troublesome components included the brakes, engine and fuel system.

Two-thirds of those cars were drivable and the problem was rectified in a day or less, the others took more than a week to put right. While three-quarters of work was done under warranty, some owners were faced with bills that ranged from less than £50 to £1500.

Owner’s view “My car has had a new engine and suffered exhaust fumes inside; fixed under warranty, but disappointing for the cost of the car”
