Family SUVs

Most reliable: Kia Sportage - 97.8%

What went wrong? Brakes 2%; Exhaust 2%; Sat-nav 2%

A mere 9% of Kia Sportages had a problem, and all were fairly minor. This meant that most cars could still be driven and were fixed in less than a week. Some incurred repair bills of up to £300, though.

Petrol versions of the Audi Q3 had fewer faults than their diesel counterparts, at 16% against 28%. Most (8%) were minor niggles with the bodywork, while other affected areas included the brakes, engine and non-engine electrics. Two-thirds of cars remained driveable, but a small percentage of owners faced repair bills of up to £1500.

The latest Peugeot 3008 is proving impressively robust so far, with only 14% of cars presenting a problem and the areas concerned being split evenly between the engine and exterior lights. A third of cars were off the road for more than a week, but all were fixed for free under warranty.

2018 What Car Reliability Survey

Least reliable: Nissan Qashqai diesel - 79.9%

What went wrong? Battery 21%; Interior trim 11%; Steering 9%; Engine 8%; Engine electrics 8%; Bodywork 7%; Gearbox/clutch 7%; Non-engine electrics 6%; Air-con 4%; Brakes 3%; Sat-nav 3%; Wheels/ tyres 3%; Exhaust 1%; Exterior lights 1%; Fuel system 1%; Suspension 1%

A shocking 47% of diesel Nissan Qashqais went wrong, with faults in every one of our categories. Most remained driveable and were fixed under warranty, but a few owners had to pay up to £300.

Almost as many (46%) petrol Qashqais had a problem. Although the faults weren’t as widespread as on the diesels, a large proportion were on the battery (19%) and engine (12%). Engine electrics accounted for 8% and non-engine electrics 6%. More than half of cars could still be driven, but some owners faced bills of up to £500.

A more modest 28% of diesel Audi Q3s had faults, with non-engine electrics the most common (9%). Next up were the bodywork, brakes and gearbox/clutch. Virtually all cars were still driveable and no fix took more than a week, but a few owners had to pay up to £1500.
