4: 2011 BMW X3
The BMW X5 was a groundbreaking success for the company as the first SUV model. When it came time to introduce a smaller offering, the result was not as pleasant. The X3 is by far one of the most unreliable BMW models ever made. The proportions of the SUV were a lot smaller than the X5, but the price was right up there next to it (via Auto Week).
Consumers who were in the market for a luxury SUV had a lot of competition to choose from. The X3 didn’t exactly cut the mustard when it comes to a suitable SUV model. With all the electrical shortcomings and reliability issues, it fell short. When it comes to a confusing SUV model, the X3 was right up there with the worst.
