4. BMW X5
The BMW X5 first hit the scene in 2000. The luxury SUV was praised for it’s performance and high end interior. The suspension was given praise for offering a smooth, comfortable ride as well as reducing body roll. As a used vehicle, the X5 can be very pricey, mainly due to the BMW name. Owners on forums have a number of complaints about the X5 though. Reliability issues are a significant problem with many owners. The all-wheel drive system, electrical system, and drive shaft are all areas of concern for the X5, and the problems seem to affect all model years. For such an expensive used car, you are better off looking elsewhere. No reason to spend that much on a vehicle with so many user complaints.
