9: Land Rover Range Rover
There was a time when Land Rover was the be-all and end-all of off-road capability. But in recent years, the brand has become more of a status symbol. That doesn’t change the fact that the Range Rover is still one of the most problematic SUVs on the road (via Motor 1).
The reliability of the model is questionable at best, and if you get a used model, it will be even worse. The head gasket failures are rampant on these vehicles, and the price to perform that repair will set you back thousands of dollars.
