Most (and least) reliable SUVs

There are plenty of SUVs to choose from, but they're not all as dependable as their rugged looks would imply. Here, we reveal the 10 most reliable, and the ones to avoid...

Most and least reliable SUVs

SUVs are popular with families, and that means reliability is important. After all, who wants their car to get stuck at the roadside with small children onboard?

That's where the results of the annual What Car Reliability Survey can be useful. We asked nearly 13,000 car owners to tell us what if their vehicles had suffered any faults in the previous 12 months. 

To quantify the responses, we categorised the faults into 15 different areas: air-con, battery, bodywork, brakes, engine, engine electrics, exhaust, fuel system, gearbox, interior trim, non-engine electrics, sat-nav, steering, suspension and other. And for each fault, we asked owners to tell us how long the car took to be fixed and how much it cost.

This information was used to create a unique reliability rating for each model – 175 in total across 31 brands. Here, we've used our data to compile a countdown of the most – and least – reliable SUVs aged up to five years old.
