I recently noticed a weird rattling noise coming from the rear side (under the back side window). When the car is in neutral (not moving) and I rev the motor, there is no noise besides the muffler. The noise is only evident when I am driving. BTW, I don't have anything in the hatch except for the spare tire, cargo cover and jumper cables. Anyone have an idea what it might be?

 

could it be the license plate rattling? Does it change with the speed youre going at? Or does it depend more on how much throttle/rpm you are at while moving regardless of the speed?

It only rattles when I rev the motor (car moving). I eliminated the chances of being the muffler piping because I checked it and it is not touching anything underneath. HRRMMMMM..???
