I have only had my rear glass out once since new and I have discovered that the hard plastic trim that is molded around the glass has shrunk and cracked on 2 places. Any one else had this happen? The local dealer has never heard of this happening and he said there was no service bulletins about this. 2011 Avalanche wit 70,000 Kms.

Your dealer is either clueless or lying.  It happens all the time.
 
It happened on my 2008 and I used clear RTV sealer to fill in crack and let it flex and expand and contract. So far so good and it's been several years since my "fix".
 
New rear windows are available on eBay. I was told to get the one made in Mexico, rather than the one made in China.
 
Is there ANY Avalanche rear windows that don't have cracked frames out there? That dealer is lying.

I pull my window out for weeks at a time in the summer. It's cracked in both corners. But it doesn't leak unless I aim the garden hose right at the seal at high pressure. Or maybe if I go thru a car wash. So I don't do either, and don't have issues with it.
 
Our new to us Black Diamond is even cracked in 2 places  :beating: our ?03 has an ?02 back window that is luckily still intact but the original 03 was cracked
