 I bought my x3 in 12/06. My first Bimmer! The third time I drove it, it quit on me. It was in the shop 9 days to re-program a computer problem. The hesitation problem others list is a perfect description of my x3. Sometimes, the hesitation has absolutely scared me. I have had a sidelight casing replaced due to moisture, have an obvious rattle from the sunroof cover and have had the lifters clacking since I bought the car. Today, I am headed to the dealer to attempt to negotiate my way out of this car into another. The only reason I'm going back to BMW is because of the known problems and my chances of recouping some of the losses on it. Do not recommend this car to anyone.
