You might be able to make a case (although VERY VERY difficult) under the "lemon" law.... my grandpa (who has nothing but time on his hands) got a brand new car due to the lemon law....
in a nut shell... if the factory cannot fix a re-occuring problem, they MUST BY LAW, give you a new vehicle.... now again, VERY hard to do and will consume a great deal of your time, but a new vehicle would be a worthwhile payoff.
Parting Shot - my grandpa got a new car due to an air leak in the rear window! NO SHIT! the rear window whistled like an SOB and he took it in multiple times. the did everything, including replace the entire door... nothing fixed it... so he got his glasses out and, via the lemon law, got himself a new car...
So, if you have the time, patience, and a viable case (I have never read the law), you could get a new vehicle out of the deal.
oh wait, another parting shot - my and my wife are long time Tahoe/Yukon owners. She has had one since the OBS! she bought an 07 denali, traded it in after only 8 months of ownership and said that is the last one she will ever buy! She hated everything about it, and it was nothing but problems. She now has an 04 tahoe... NBS FTW
