Dealer found source of what sounded like a fast tinny rattle in dash of my RDX.
The problem was a brace under the cowl cover between drivers fender and cowl. A bolt was mis-threaded and about 70 degrees it went away! A hard one to find, credit to Acura of Boardman, OH.

 

shm - I wonder if your noise is similar to mine? I have a tapping/snapping sound near the top centre dash that can really get fast/persistent. The dealer has had the centre grill off and added padding a couple of times, but it's still there. Could you describe your rattle in more detail?

 

Hello DJ75


The rattle sounded like loose metal vibrating, which it was! I believe there was

another tread posted about a loose fitting sun sensor which is in the center of

the dash, you may want to check that for tightness.

I know it's been awhile. Do you have a picture of where the bolt is?

 

Have you found the bolt that got loosen?

 

A while? We're talking 11 years! I think this is the oldest thread revival I've ever seen. I highly doubt either of these guys are still active on the forms with the 7 total posts between them. Hopefully someone else will see this and chime in though.
