I agree that trying to identify a noise is very difficult. I tried looking at the clips, but I think you are referring to the actual clips on the cover--I removed mine. I've never found that cover useful in the 2 RX's I've owned. One of the annoying things on the 2010 is that there is no storage under the cargo area for it--so it's in my basement until resale time. Looks like I'll have to bring this up with the dealer. In my experience, talking to a dealer about rattles usually doesn't get you anywhere... could you elaborate on what 'clip by the rear door' you are referring to? I'm not aware of any clips other than the ones that hold the cargo tonneau cover? Thanks... I think I got it. when referring to the rear door, you are referring to the rear hatch, not the rear passenger doors, correct? Thanks for the pics. I gave completely removed my cover from the car as it just gets in the way for us....

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!

What psi are your tires at? I was just able to check the front tire and its was 40 or 41 and the side said that it supposed to be 32 so it does seem to be over inflated. I will be checking all tires today and making all 32, that should make it better!!! The manufacturer's suggested psi is 30 all-around (on my 09RX350AWD). It was the same on the old RX300 I had. I ran/run both at 32 psi, and am happy. The Michelins on the 09RX show max of 35 on the sidewall. I tried running them at 34 and they were too hard, the suspension 'crashed' a little. So, after a little experimentation - for me and I do not dispute others may differ - I found that the 'best' psi on the new RX was the same as for the old, i.e. 32. Let us know how it feels! Good luck! So I changed all the tires to 32-33 and the ride did get a bit better, but I think eather the suspension here just not as it was on the 2004 RX330 or the bridgestone tires are rough. Not too happy :( A comment on the tires. I was prepared to receive the Bridgestones based on posts suggesting Lexus went with these. As a matter of fact I made a comment of disappointment to my dealer--to my pleasant surprise, my RX came equipped with Michelins. I'm wondering if Lexus changed their approach to which tires to equip. I picked my vehicle up on Oct. 30th. Are others who have recently received delivery getting B's or M's? BTW, very happy with the ride of my RX--I find it better than my 05 RX....

I understand now! It sounds like your RX has the same HVAC buttons as a non-navigation RX. That's a bummer. The automatic recirculation feature is nice although I don't know if I would miss if I didn't have it. I do have the sensitivity on mine bumped up a knotch for those rare days when I'm caught in stop-and-go traffic. It is probably more a source of entertainment to watch it switch back and forth between inside and outside air. Now what we really need is a sensor for interior exhaust fumes ... you know ... the fumes that are sometimes emitted from the southern end of passengers after the consumption of Boston baked beans. ;) LOL--you're right, not a really big deal. I'm more frustrated that it was *supposed* to be part of NAV. Since I live in Boston (baked beans ;) ), we have a lot of tunnels and I park in a public garage, so I end up switching modes quite frequently--oh well...still love the vehicle. Now if I can just find a phone that will download my contacts :(

Do you have the "Air intake control button" labeled "9" on page 279 of the 2010 RX350 navigation manual? If you have this button, pressing it repeatedly cycles the system through three modes -- exactly the same as a similar button works in my 2000 LS400. The three modes are described on page 284 of the 2010 RX350 navigation manual. I will include page 303 from the 2010 RX350 navigation manual simply because it points to page 410 which (poorly) shows where the sensitivity is customized by selecting "Vehicle Customization" and then "Climate Settings". Have you gone into the Climate Settings screen to see if has the sensitivity customization feature? If your RX350 isn't like what is shown on the attached 2010 RX350 navigation manual pages, could you take a photo of the buttons you have and attach it to this thread? If your A/C system is like what is shown on the attached pages, then you have a system that automatically adjusts between outside air and recirculation depending on outside air quality. Your experience with Lexus dealership staff not knowing much about the cars they sell certainly matches what I have experience over the past 20 years. My "favorite" experience was trying to convince two service writers that my 00 LS400 has DRL. They argued forcefully that DRL didn't start until the 2001 model year. They didn't even apologize when I showed them information about DRL in my owners manual. Thanks for the photos--I will take a photo of mine, but in my manual they show an 'A' version and a 'B' version. One version looks like the photos you've attached, however the other is what I have in my car--where the word 'Auto' appears on the button in your photos, I have a second car icon with a circulation arrow in it--just like most cars with internal/external air circulation. When I look on the Lexus website, it appears that at some point (recently), they moved the auto feature into the luxury package. Earlier documentation shows this was part of the Nav. I tried to get the luxury package, but they don't seem to exist in New England....Thanks for your help with this!

Thanks Jim. This is different than what I am referring to. If your RX has this feature, one of the little 'car' icons will be replaced witht the word 'Auto'. Apparently several users on the Edmunds site with Premium/Nav do have this feature. I now have to figure out why mine does not. My dealer is of little use as they did not know that (or the auto high beams) even exist--this is after going to 'Lexus school'...I was explaining the features of the car to him!! Anybody have suggestions of who I can go to to find out why this feature isn't on my vehicle when it is supposed to be?

I am using it since it is free for first year. Very convenient and it works as advertised. I don't plan on signing up after the one year trial period, so I am wondering if I wll lose my input destinations at the end of the trial period. The only flaw I have found with it is that the voice system does not seem to recognize edestinations. To use it, all you have to do is register on the web site....

Thanks for your reply. I do have what you describe. However with 2010 the auto recirc. mode I am referring to is supposed to have a setting where it automaically detects smog etc (like when in a tunnel or garage) and set itself to interior air circulation. Not a big deal, but I just curious as to why mine didn't come with this feature. The way you can tell is that there is a second 'auto' button next to the circulation button.

I just picked up my 2010 350 and it is supposed to have an auto recirculation mode with the Nav package. It appears I don't have this mode. Does anyone else have this option? Thanks in advance...

Is anyone finding that the front seats of the '10 RX350 are very uncomfortable? There have been several posts on other forums regarding this and I'm not sure if I'm being overly sensitive. I don't recall my '05 330 being this stiff. Thanks in advance for any feedback...
