I had an issue with mine when it came up at highway speeds, the down force made it rattle. When it was down it was quiet until I hit a dirt road, then it rattled like crazy. Squeek or rattle, I don't know if it is the same as yours but the dealer tightened down the hatch lid and it completely stopped. You can check to see if you have the same problem buy pushing down on the hatch and letting go quickly. If it squeeks or rattles, that's the problem. Good luck!
