I purchase a 2011 x5m and my breaks squeeked horribly while reversing only. After 2 trips to two different dealerships I was told that these were "performance brakes" and that it was normal and could not be fixed. I called bull shit and got the owner of the dealership on the phone and demanded them be fixed. Apparently to fix the problem you need a mechanic rep from BMW to fix the problem, this guy comes around to the dealership a few times every couple months to fix certain problems and it worked. Do not live with that god awful noise. It can be fixed. When you spend 100k for a truck there is no reason to be ashamed of the brakes!
