going in for 20k (250AWD) in a coupl of weeks, probably just going to get an oil change but have a series of other problems to get looked at. anyone have any experience with the below (I would love to have some hints for the dealer before he just starts trying to fix. I had the dash TSB done about a year ago)

1. Sunroof wind noise - excessive. last time they said they greased the gasket, but it didnt help. the IS250 AWD loaner they gave me was silent in the sunroof.
2. rattle, passenger side, cant really figure out where. sounds like right side of glovebox.
3. "crinkle" noise aorund nav - sounds like the outher bezel - not as bad when car cools off, awful when its warm (When i push on the center sonsole the whole thing makes the same noise - very odd, and disappointing)
4. Clicking noise from B pillar, sounds like right at seatbelt attachment point. Right at my left ear so this is especially annoying.

Any help to point them in the right direction would be great, i fear they are going to come back and say he can find nothing wrong...

 

Never had item 1, but have had 2-4 for 2 years now, and 2 attempts by the dealer to repair the rattles/squeaks/etc. have resulted in poor interior fit and finish in addition to the rattles. I finally gave up, and I just live with it now.

The only car I've had that makes as much interior noise as this one was a 1991 Pontiac, and that car was a complete POS. Draw your own conclusions about what the bean counters are doing to the quality of Lexus vehicles. Now, undoubtedly, this post will be followed by several people saying their cars are quiet as a vault, etc. However, there have been enough rattle, fitment, and other issues brought up in this forum to call it a problem, IMO. Hang out in the last generation forums for any Lexus model discussion on this site...you'll hardly read about rattles.

 

so its not just the IS, but all new Lexus vehicles rattle more than they used to?

 

All recent redesigns seem to, anyway, with the possible exclusion of the LS for obvious reasons. Read the ES forum for awhile if you really want to see some frustration.

 

#2 I wonder if it is due to the seat. I had an issue that is covered in a TSIB somewhere that a tab on the seat will rub. This rubbing was noticeable on my car when I made quick turns.
