Rolled down rear window on my BMW 325i and hear a loud pop like breaking glass. Opened the door up and sure enough it was the window regulator that was broken on my car with 46K miles. BMW should be forced to repair this under a recall.

Just put window down today passenger side window will not go up. Bmw should recall the junk materials they used in such a pricey vehicle. Hardly ever put my windows down so cannot blame it on overuse.
Rear window regulator broke in the down position. You can hear the motor trying to move the window when you hit the button, but nothing happens. Part had to be replaced at the expense of $240

Window regulators went out on THREE out of four windows when the vehicle was only a year and a half old. Cause was defective regulators covered under warranty. I also had problems with the front passenger window as well.

Just had this happen to me today. Put rear window down and heard a loud cracking sound. Won't go back up. Nothing was done to the car, just simply used the window and if stopped working. I'm hoping BMW will cover this under some sort of warranty or have a recall.
