My '04 has it and in fact I just searched "shifter rattle" in this forum anout 2hrs ago. 2500-3000rpm, buzzing rattle from what seems to be the shifter linkage. It's intermittant but annoying. Actually you can't hear it if you hold on to the shifter hard. Anyway, I had the car at the dealer yesterday for them to look into it, and the answer was "no TSB, don't know what to do for you". In another thread, someone said that someone else got his fixed with a new shifter. I'm going to see if it goes away before going back to them.
I have to take it back in sometome because of my other problem - the well-known jammed door lock issue. They epoxy'd the lock rod to the clamp that moves it up and down yesterday, it jammed again this morning, and they epoxy'd it with a stronger glue this afternoon. They've ordered a part that is supposed to fix it, but it's coming from Australia (!), so they'll let me know when it gets here.
