Not yet on my e32 but re-glued 3 out of 4 on 528e (archive)

A bit of a pain to repair & align properly so the window doesn't bind going up & down in the channels. I peened the rivets on the metal clevis which grips the glass to hold more snugly & got a strip of butyl rubber from a glass shop to slip in between & J.B. Weld (great stuff!) to keep it all together. For extra strength, I ran a bead of RTV along the entire bottom edge where the glass rests on the metal rail. It's worked well for another 3 years so far. Just have to convince the wife & kids the doors don't need to be slammed shut, just slightly more firm than the refrigerator is sufficient.

Just about to go to bed last night around 11:00 pm when my significant other casually mentions that the driver's window will not roll up and down. Out with the extension cord and portable light. Removed the door panel and found that the left-hand bottom edge of the window was no longer attached to the metal support bracket. The glue holding the glass in the bracket had failed allowing the glass to move out of the bracket and just flop around. Judiciously manhandled the glass back into the bracket, slowly raised the window until it fully closed, then disconnected the electric motor to prevent "accidental" (that's the term my children use) use of the window. I left the door panel off and let a local windshield company re-glue the glass.

I haven't seen or heard of this problem before. About a year ago I had to replace the metal plate on which the window mechanism pivots. However, I did notice that this was not the original glass (no BMW symbol and small glass pieces on the inside of the door) so I assume that the glass was replaced prior to my ownership. I would have thought that a new window would have come with the metal brackets pre-glued.
