My Fiesta has some sort of squeek/rattle that appears to be coming from the lower center dash area but I haven't yet narrowed it down. Of course the superior noise isolation of the Fiesta makes any noise sound like it's a base drum. I'm a little nervous about letting the dealer tear into the dash until I have a better idea where the noise is coming from. Has anyone else noticed any similar noises? Have you figured out what the cause is?
