Did a search, couldn't find much... 2004 E53 4.4. My wife opened the sunroof yesterday, now the small back section will not close. Because of this the main sunroof will not open. I've got to find a fix before we get rain again or I'm gonna go out there and hammer it shut... Im not sure if I got a lemon or what, but something breaks about every three weeks on this vehicle. It is an absolutely beautiful SUV, and we've only had it a few months, but I'm beginning to hate it.
