2005 H2, purchased 10/2004 there is a noise that cannot be located and repaired. Sewell Cadillac, dallas, Texas replaced the front differential (it had metal shavings in it), replaced rear springs observing they were over extended, bubbled and warped. The car in two separate repair tickets has been in the shop 7 days each time for a total of 14 days. Is doesn't appear this problem can be found or fixed. There is a "dragging" noise upon acceleration between 20 - 40 mph. It is very uncomfortable hearing this noise. My neighbor had her wheel come off of her 2003 H2. I was required to fill a blank so I chose power train only because it seems closest to what it might be, I'm not sure. Sewell keeps trying to fix the problem, just unsuccessfully.
