Hello...
I too have the same window noise issue and it's driving me nearly insane!! I've been to the dealer 4-5 times now and I thought it was fixed by installing new weatherstripping on the doors and windows that had been ordered as new parts, etc., all fresh. Upon redriving it was fine - they washed the car and the noise was back but seemed much better after car dried. This was on Wednesday and it's now Sunday.
BUT, on the way home from a road trip, the noise is still there and although it's a bit better - it's not silent like it was for the 5 minute test drive after the new weatherstripping. UGH.
I am not sure what to do - this is a lease that I've had since mid-November and it's getting ridiculous. Fwiw, I do notice that when I push on the window, it seems to stop the luffing/rattling noise. For me, it sounds like plastic being scrunched very quietly - or - if you push on the window with the door closed, it replicates the noise in my vehicle. (In case you need to demonstrate the noise for the tech).
Please update with what you've all done and if it's stayed fine for a while.
Thanks for any feedback!

My 2009 Rx350 does the same thing. The noise is driving my crazy. I've been into the dealer three times. They have tried messing with the door adjustments, applying grease to the window, and adding foam padding over the side airbags. The squeaking seems to get worse when the weather is bad. If anyone else has a suggestion I'm all ears.
