I would go back and raise ****. If it is an engineering defect that is corrected in 2012... GM should be eating the fix. There is no way a consumer should have to buy an AC condenser from a rock on a brand new, unmodified car. As the AC system is part of the emissions control system ( dont ask why it is ), that is a warrantied part until the useful life of the vehicle. Improper engineering design is not a justifiable reason to not warrant the repair based on California Air Resource Boards findings...
I would call GM directly.
