just bought 05 QC and I love it. Two issues, first is it me or does it almost sound like a diesel from the back when running. You would think they would put some more growl in this thing stock. Also last night while closing the sun roof, I had two rubber channels fall out. Both about a foot long and one has felt on it. I looked up there with the roof open but couldnt figure out where they go. Both came off the drivers side, and ideas or does anyone have a diagram of sunroof design?
