Excellent!!

After driving mine yesterday, my noise was gone, but we'll see after more time.

Sucks about the regulator, but at least it was pinpointed!

There must be 2 separate issues.

I took the panel off yesterday and noticed all the little silver screws could use some tightening which I did (didn't help) but I didn't have anything to stick between the plastic which I noticed was loose as well. I have a feeling mine is the regulator as well though because it doesn't seem like the noise would be coming from that plastic box especially because as soon as I touch the window down a millimeter the noise stops so I'm guessing it's something inside the regulator...I'm dreading dealing with the dealer on this cause I know they're gonna give me bullsh*t. I'm doing my oil change this saturday so I'll find something to secure the white plastic box just in case and keep everyone updated.

my noise came back :( must be the reg.

I have the same problem. Had to take my Z in for a recall fix today. Steering wheel lock. N/C of course (would have cost $750) but while there I had them check out the buzz in drivers side window. They said it was the window regulator.They would have to order the part and will cost $425 including labor to fix. I found the regulator on E-Bay for $65. Will try doing it myself first.

Ditto... getting one ordered under warranty! My tech spent over 3 hours trying to figure out how to silence it. Pulling the regulator motor didn't fix it either.

I had the window rattling problem shortly after getting the car. Dealer was able to adjust regulator and didn't have to replace it.

Just as an update, I got the new regulator assembly installed. Those who pointed out the loose rivets are correct. My tech compared the two and noticed there are plastic insulators on the rivets keeping them still this time around.
