This is my 1st post but I am not new to Crossfires having mine almost 2 years. I have a 2004 White Limited Automatic. My problem and I have done many forum searches here but still have not found my problem. When I am accelerating from a stop but not hard I have a rattle or buzz sound coming from what sounds like the rear of the car. I found out about the TSB for the hatch latch and it was done yesterday but did not help, I tried adjusting the rubber stops, pulled them all the way down and the hatch closes fine and everything seems tight at the hatch but still has the same buzz. It only last a few seconds and mainly at about 1,500-2,500 rpm and only from low speed to about say 50 mph. Once at hwy speed I don't hear it. I placed some tape/rubber behind the rear license plate, did not help, rubber under the heat shields on each side of the tail pipes DNH, removed all the spare/flat kit stuff DNH, place some rubber under the cover where the upper tail light hits the glass DNH. I seen how the bumpers are to be adjusted but maybe I did it wrong but I can hit on various areas at the rear and under the car but nothing replicates this sound with the wind up or down. It almost sound like a glass loose/vibration type of buzz but the windows in the rear seem tight. It has been doing this for sometime but with my 3 year 36k running out soon I want done with it. I hate taking it to a dealer anyway. Can anyone shed some light on this buzz, give me another route of ideas. Thanks Mike
