 I was very happy with the v6 limited version up until the sunroof shattered.  Driving along on the highway with no trucks or cars around, not near any underpasses, and then a great big crack and wooshing wind noise.  Dealer is running away from the issue, I read other people had this problem.  The car was four months old when it happened.  All glass is covered with no deductible so it won't cost me anything, but there is no question that this is product defect not a stone.
