open a claim with gm. you are not that far out of warranty. if you have all of the service records and work done available, that will help. they probably will not pay for the whole thing, but might help with some, or most of the cost. it is worth a shot, I have done this with a 99, a 2004 and a 2008. water pump, master cylinder/brake booster and a steering rack on two of them. only claim I have had denied complete was the large fuse box (I forget the name) under the hood on my 2008. 1 fuse bank (just 1 fuse slot) went out and it was for my third brake light.
