You Better Hope Your SUV Isn’t on This List

If you are thinking about buying a used SUV, you’ll probably want to review the ones on this list. According to CarWow, the following SUVs make up the list of the least reliable SUVs of the last decade. For the past 10 years, these SUVs have been giving owners a lot of trouble. They range from budget models like the Mazda CX-5 to luxury SUV options like the Range Rover or Porsche Cayenne.

In order to create this list, the folks at CarWow got together with Warranty Wise to compile this list of the least reliable SUVs. The data comes from multiplying an SUV’s probability to have issues with its average cost to repair. This simple math gives us a nice list of SUVs we probably want to steer clear of.

The least reliable SUVs of the last decade

The first on the list of least reliable SUVs is the Mercedes GL. CarWow host explains that the newest model of the Mercedes-Benz GLS is still too new to qualify. However, if you are buying a used SUV, the Mercedes-Benz GL isn’t exactly what we’d call reliable. It costs an average of £1,180 to repair the common issues with electrical problems. The highest repair claim reported was for £4,526 due to infotainment issues.

You also might want to avoid the BMW X5. Like the Mercedes-Benz GLS, the current BMW X5 isn’t included because it’s so new. But the BMW X5 takes its place on this list of least reliable SUVs with an average cost to repair of £1,593. These repairs are typically for suspension issues. However, X5 engine problems cost up to £9,937.

When buying a used SUV, it’s smart to check out the best and the worst. The Land Rover Range Rover is one of the least reliable SUVs of the last decade with an average cost to repair coming in at £1,388. That’s for problems with the air suspension. If you end up having Range Rover engine problems, your SUV could cost up to £11,932. That’s easily over $12 grand USD.
