go99 said it's coming from "under the car," which is NOT the luggage cover. I've tried everything to secure the two luggage covers (the one clips to the rear door, and the one that retracts and runs across the whole back). When I go over a bump, it still rattles and drives me insane. I don't like the look of the rear without these pieces, so I have to choose between aesthetics or no rattling. Disappointing.... The suspension in this thing is also more "truck-like" than I expected, so that doesn't help with the noises. I'm curious to see what "well documented noise under the car" go99 is referring to????? Could you elaborate on the rattling noise? I have a rattle when I go over bumps, but it sounds like it's coming from the passenger side somewhere (almost like the rear passenger side). I removed the tonneau cover completely to no avail. It's driving me crazy! Thanks Try securing the clips that hold the luggage cover near the rear door. Lock them into place. It is a well known issue and the dealer even mentioned it when I bought my RX. Thanks....I'll give that a try before I take it in. Very annoying since what I love about the RX's is the quietness!

If you have a 2010 RX350 or RX450, you can't upgrade to v9.1 yet. We have HDD navigation systems and the partition is slightly too small for the latest software. Lexus is (apparently) revising the software and will be releasing it in a month or so.
