I've had the same issue from day one. I pointed the noise out to the salesman when I test drove and he said, "its the just the differential", I was so eager to get a vehicle I didn't ask enough questions about it and should not have got the truck. Im sure it would be a problem if I tried to sell it. Mine is a 2013 1500sle, 4wd, purchased in august of 2013 now has 9,000 miles. I never believe a word a service tech or especially a salesman says, will I ever wise up? Should have got a Ford or Tundra. I don't think I have the stomach to take it to a dealership, and I wish I could believe it was the muffler system but that's a tough one to swallow, but glad it relsoved the gentlemans issue in the #52 post. Has anyone else had the muffler system replaced for the "clucking" noise. Mine is as many have described. Almost seems more noticeable when the vehicle is cold, but not certain of that. GM ...lets see will I feel better if I cuss on this post? $41,500 MSRP for this? Gov't Motors, ugh.
