Well I stopped by Courtesy Nissan in Richardson to see if they could shed any light on my ratrtle problem, and they did. One of techs rode around the lot with me and I pointed out the problem. We then opened the hatch and drove around and the rattle was gone. So he suggested I adjust the position of the hatch release. Easy to do, just pull off the plastic piece on the inside of the trunk by the license plate, loosen the two bolts and slide it over just a bit, and then tighten it all up. I tried it Fri. night it improved the rattle alittle, but I did not want to go back in loosen it, adjust it, tighten it, drive around the block any more so I will probably try messing with more later. Just glad it's nothing major! The guys at Courtesy were very helpful! Hope this can help some of you out who had the same problem.
