The total brake failure and T-Case rebuild are totally un-acceptable.
Was the serpentine replaced and a precaution or did it break?

Your other problems seem relatively minor and fixable.

How have you been treated on the repairs?

My battery went dead too, my A pillar makes noise above 70mph and my check engine light has just come on. I hope it isn?t the cylinder head. If the Hummer turns out to be a bummer I will go back to Jeep or Toyota. This is my first GM product and so far the quality and fit and finish seems very good.
