So I noticed today while I was getting gas that the drivers side window has a considerable amount of lateral movement. I tested with the window fully up, halfway down, and about two inches from being fully down and in all cases, I could “slide” the window up, down, and side-to-side about 1/4 to 1/2 inch. Moreover, I also encountered some in-and-out play; it’s almost like the run channels are too wide and too far apart. I compared against all other windows and none had near the play the drivers side had. Also, I could replicate the sound I get when I hit bumps by pulling the window back toward the rear and just letting go. I tested a theory by going down a bumpy road, putting the window halfway down, and pulling from the front toward the rear, and guess what? No sound. I think the window is moving within the run channels over even the tiniest bumps and making the scrunching sound against the material. Looks like another trip to the dealer.
