	2008 gmc sierra denali has intermittent fuel gauge operation. after filling up the vehicle while driving the fuel gauge needle will drop from full tank indication to empty tank indication even thought the tank is fuel of fuel. the dealer has removed the tank and replaced the fuel sending unit, but has not resulted in a fix just an educated guess. also in the mornings the vehicle experiences a very loud knocking noise which when confronted at the dealer was told that this was a normal noise. occurs everyday in the morning and when leaving work in the afternoon. *tr

	External left rear door handle pulled off when simply opening the door 11/15/2010. external left front door handle pulled off when simply opening the door 12/15/2012. two door handles pop off on a new vehicle not a defect? same flimsy plastic fastener attachment broken in both cases. google search indicates this is a common defect experienced by numerous owners that gmc and chevrolet will not admit to. the gmc dealer even acknowledged it's a defect! repair cost - $300/handle!
