i have a very annoying rattle in the driver door panel that i can't figure out where it's coming from. it is very loud at speeds less than 40mph. so i hear it alot - driving home on our very smooth asphalt roads, driving my kids from school, anywhere low speed is required (which is about 50% of my driving). very irritating.
i just tried lowering the window and i don't think that changed it much. wondering if yours sounds similar? BTW, are rattles something the mobile service techs able to deal with, or is that strictly a bring-to-service-center issue?
