GM has, to their credit, offered to pay 1/2 of the ~$750 replacement cost. I get the impression that they would have sprung for all of it if the service manager at the local GM dealer had been willing to tell them that he was sure it was a case of solder separation and that there was nothing that the owner could have done to prevent it and nothing that the owner could have done to exacerbate it. The guy was unwilling to say anything other than that the tab was off. He looked at the window about 5 seconds - I am NOT exaggerating. The dealership would not have to contribute to the repair in any case.
I must say that I am impressed with GM making some attempt to stand behind their product, even in the tough financial situation they are in. I have had a series of things break on my Yukon XL that should not have broken and that makes it tough for me to want to buy GM again, but the attitude of GM customer assistance does go some distance to balance the bad experiences. God, I hope GM manages to turn themselves around financially and improve their reliability up to near-Toyota levels.
