Anyone that lives in cold climates ever have their back window squeak or sound like a piece of ice is stuck somewhere back there? I have made sure the car is clear of any ice/water and on really cold days, it sounds like something is moving back there. It did it on my old Accord as well. Any ideas?

It's probably the rear deck rattle or I've heard that there is space between the 3rd brake light and the rear window and they will rattle. Heard a few people put tissue/TP/whatever in there to stop it

 

Yes I have this problem all the time in my 07 TL Base, its like the seal is not tight enough so water and ice builds up in the weather strip soon as I clean it out the noise is gone, very annoying as my 03 Accord coupe did not do this ever.

I am thinking I should try some Shin-Etsu Grease (Heatsink Silicone Compound) on the seals and see if it helps.

 

Don't have a TL, but FWIW, my TSX also gets a quick squeak from the rear window when I go over bumps. This definitely started when it got cold and ice formed on the car. So Im thinking its coming from the outside hopefully.
