Windshield cracked up middle, we've seen many GMC products with the same crack.
The entire rear end had to be replaced, the dealer said they see this quite a bit.
Worst problem is in differential - it makes a sound like airplane ready to take off - can't believe that a 4 yr. Old car can have this happen - have spent well over $5,000 since I bought it - really upset !.
