I have had what I thought was the typical hatch rattle that plagues most crossfire drivers. After proper searching, I have applied every known fix. I'm talking about 4-5 sessions of adjusting bumpers, electrical tape wrapping, velcro padding. I have been fooled several times that the demon rattle was fixed. I would run the car around the block and everything would seem fine. Then it would pop back up the next day.

I don't know if I can fit, but I'm about to have my wife put me in the trunk and drive around with me back there. From the driver seat it seems to be in the hatch lid area. It doesn't seem to be exhaust related. In all my adjusting, I have perceived a difference I think. Sometimes, I can get it to rattle by putting the car in gear and power braking slightly.(a certain resonance rpm just off idle).

Looking for any input.
