My cabin rattles shift around from the radio stack to the glovebox to the B-pillar (making them all "non-reproducible" at the dealer, unforch)... but I have started to hear a consistent ticking/buzzing noise from both of the little red reflector discs on the door interiors. Only on some road surfaces and at some temperatures.

Am I crazy or has anyone else observed this? If so, is there a simple fix?

 

I thought mine were buzzing too. Turned out to be the door panel itself. Both doors have done this as well as A-pillar covers etc. Press or pull on door panel while motoring and see if it stops buzzing. I have stopped all buzzing and rattles in my car, '03 w/16k, by wedging small pieces of flat rubber under or near annoying panel. Works great so far.

Anyone have the drivers seat squeaking like crazy at the recline adjustment area?

 

I get the buzz as part of the H/K stereo vibration. The reflectors didn't join in the fun at first, but now they're part of the vibration party. I'll be getting my first checkup in about a month, but up until then I don't know of a fix.
