Thanks for the detailed explanation. I have to tell the family to WATCH the gas gage.
#154 of 202 RX400 slight noise problem
Mar 15, 2006 (5:51 pm)
Only 500 miles on my 400 so I have not gone back to the dealer yet. Before I do, I wanted to check if anyone else has experienced this.
At speeds over 30 MPH there is s noise coming from the back that sounds a little like a metallic fluttering. I thought it might be a tag or something loose underneath, but nothing found. With someone in the back seat to help listen, it seems to be narrowed down to coming from under the seat, which would mean possibly something in the battery area. Could it be something with the battery ventilation operation?
Anyone else have a similar experience?
At speeds above 60 the road noise takes over and most of the time I cannot hear it. So I know, the solution is to drive fast!

On our Highlander the license plate was fluttering. On the RX400 the latches for the self retracting cover were rattling. Took a while to find both. For the latches, just push them down into the latched position when the cover is not installed.

It took my more flexible son contorted in the luggage area of my 400h to find this same rattle. It's exactly what you found and repositioning the latches stopped a noise that drove me nuts for an entire 4 mo vacation trip!! Told my dealer, but they seemed amazed like no one else had ever complained about it.

The dealer installed some little adhesive sound insulators on my latches. It seems to be working. They heard the sound, too.

Just got my RX back from the dealer yesterday. I brought it in for (among other things) the same issue. Mine turned out to be an exhaust system heat shield under the vehicle, which I suspected originally. That's why you hear it from the battery vents: the soundproofing probably isn't as thick there. They "made an adjustment" and now the sound is gone!
