Buzzing sound at certain speeds
I have had my 04 xfire for 4 years and have about 35k on it. It has made this buzzing sound coming from the rear since I have owned it. It only occurs when you are accelerating slowly and only at a certain rpm and it goes away but it happens all the time. I had the rear latch replaced with the new type discussed here, adjusted the stops, checked my license plate frame thinking it was that. Any ideas? I read somewhere it could be the heat shield material above the tail pipe area, messed around did not see anything loose. I stopped bugging the dealer years ago but figured maybe post here and somebody may know or have had this noise. thanks for any help.
