Seriously, this is now getting really really obnoxious. Every now and then ill be driving and then the hatch starts rattling and doesnt stop for like 20 ****ing minutes! its so obnoxious i want to pull over and ditch the car. Anyone have any ideas on where its coming from? its hard to find considering im driving everytime it does it. Then it wont do it for the dealer... stupid car, but i do love the Z...

 

Why don't you just put on some sort of sound dampening on your hatch then, like Dynamat. It will reduce road noise and stop most of your rattles. I put it in my old vehicle and it was a night and day difference.
