I would fire over a pic, but it's currently at Land Rover Portland getting the rear side window replaced because it was falling off the truck. (the common issue on early builds of the rear quarter window falling out / coming adrift! ). But it basically looks like a new one if you google one of those.

 

Is that being fixed under warranty? Mine is an early 2021MY build, but I haven't had this problem... at least not yet.

 

Yup, under the 4 yr/50K factory warranty still. Grab the trailing edge of each of your rear door windows. (the part of the window that doesn't move, where the painted portion is). See if they wiggle. Mine went from super tight to falling off the truck in a week when the weather turned cold this year. No idea how or why. Luckily before my warranty ran out next month.

 

Just had a good look at my windows before I dropped it off this morning at the dealer. They had it a week and a half ago to fix my heated steering wheel, and now my horn doesn't work. Also, they will be fixing my annoying rattle in my door bass speaker (which I tried too remedy myself with a thread you started from a few years ago, but only partially fixed the rattle). Anyways, my windows seem to be fine. No movement whatsoever.
