This problem started on May 15, 2019 and I have the video on file on this problem. I called the car dealer and I showed them the problem. First they lubricated the window that day. But the noise came back the next day. I called the car service again and insisted to replaced the window. Finally the manager listening to my complaint. They fixed it and replaced the window. Few days after I have noticed that every time I rolled down the window it looks like loose. So I took it again to the car dealer on the 18th. I spoke to the mechanic and the manager and I was told to that they are going to call Acura if they can send the parts to fix the problem. Right now my husband is on the way to bring the vehicle to the shop. I will find out tomorrow if they have finally fixed this issue.
