Mine's been doing the same thing. The most annoying part is that the pinching on my window is causing some bubbling on my tint.

Squished seal
 

My BRZ is doing this now on the drivers side.
I also now have the window scratches (according to some posts, thre are felt guides in the door and if they come off, it can scratch the window.) I wonder if it's enough of a movement when those fall of to be causing this seal issue.
Anyone able to check that?

Corporate got back to me and said that since I've documented the issue with them they will "work together" if I need support after my warranty is up. I guess that's good-ish news.

Mine only does it after it rains or a wash along with the squeal. I just pull it back and it returns to normal.

Anyone with a 2013 build date have this problem?

I still haven't replaced mine and now when I wash the car I get some water inside the window, I guess it will get worse and worse with time.

Had my drivers side fixed Tuesday at the dealer under warranty. Next is the passenger side.

Are you talking about moisture within the first 1/4" or so of the windows? I see it too and that seems normal to me, unless moisture is actually getting inside the cabin past the seals I don't think there's a problem.

This is starting to look like it may be part of regular maintenance once every 3-4 years or something. Of course they could be holding up better than people expect and they just look funny (barring the folding over misalignment issue).

actually is water dripping in the inside the galss down to the door panel, I'm going to take a picture as soon as i wash it again

My driver window smashes and pinches the upper part of the rubber seal. Looks like shit I can see it in corner of my eye. Hate it

I noticed this happening to mine today... looks like a trip to the dealer will be happening soon enough.

This is now happening to me. 2013 BRZ, 10,000 KM.

Only driver side is doing this. Passenger side is fine. Usage is not the cause as I always roll both windows down, and even if so, this is a defect from the engineering department.

Been raining the past few weeks and temperatures have dropped, but I park in a heated garage...

Give the window and the seal a good cleaning with warm soapy water. This fixed my issue permanently. Worth a try.

My passenger side has been doing this for a long time. The other side has recently started. No leaks yet on either one.
