Hello everyone need some input here. My 2011 328i passenger side window squeals like crazy during the day when its hot. The window squeals when lowering or raising.

When the weather is cold or winter comes back the noise vanishes.

Have any of you had similar issues ? Do I need a new rubber seal ?

Already tried silicon spray and etc.

Same problem here on driver side window.
I am interested in this issue too.
Anyone who solved this problem?

Silicon spray makes the squeaking worse. Try DuPont Krylon. It come in a tube. It should eliminate the squeaking.

I had this on driver side last year. First cleaned the dried dirt along the edges of the window. Then applied some Honda ShinEtsu white grease at the same edges, moved window up and down so grease made its way in the tracks. Applied some more, then it is still quiet.
