10 most unreliable 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 least reliable, according to owners...

Most unreliable SUVs

SUVs are popular with families, and the last thing anyone wants is to be left stranded by the roadside with a carload of children. So, reliability is important, and that's why we asked more than 18,000 people to tell us what went wrong with their car in the previous 12 months. 

The results can be found in the What Car Reliability Survey, with us considering 14 different areas: air-con, battery, bodywork, brakes, engine, engine electrics, exhaust, fuel system, gearbox, interior trim, non-engine electrics, sat-nav, steering and suspension. For each fault, we asked owners to tell us how long the car took to be fixed and how much it cost. And from this information, we created a unique reliability rating for each model; 218 in total across 31 brands.

Here we've used our data to compile a countdown of the most unreliable SUVs. These are the models that spent the most time in the garage having faults put right and which cost owners the most in repair bills.

The least reliable SUVs

10. Land Rover Discovery (2004-2017)

Land Rover Discovery (2004-2017) front three quarters

Reliability rating: 82.5%

Don’t assume that the old Land Rover Discovery sits in the bottom 10 for reliability because it’s old; the latest version scored just 1% better, and 41% of both models suffered faults. Around half took more than a week to fix, and while most were fixed under warranty, some cost as much as £750.

9. Nissan Qashqai petrol (2014-present)

Nissan Qashqai

Reliability rating: 82.1%

Petrol Nissan Qashqais performed slightly worse than diesels: 48% had a fault compared with 42% of their diesel sisters. Battery trouble afflicted 24% of cars and 6% had brake issues and problems with their engine. The only upside is that half were fixed the same day and three-quarters of work was free.
