Dang I hope you can find the issue. My squeak was so loud when I first got it so I was like omg that’s not right. But I was so busy at the time I was going to wait for my 1500 mile first oil change and ask them to look at it then. But I slowly went away and I no longer hear it. Does it make the sound all the way up and down or just near the top or bottom?Well, guess I spoke a bit too soon. I went out this morning and went to roll down the window and was greeted with the loud squeak once more. I'm booked for another service appointment for Wednesday - hopefully they'll do a little more than just roll down the windows and shoot some grease into the rails.
