2018 IS300 Rattles
Hey guys,
Have been trying to solve some rattles coming from the front passenger side of my new IS for a month or so now. I wanted to see if anyone else with one of the newer models had any rattles coming from the front passenger side dash/glovebox. I’m very surprised there are any rattles with just 2,000 miles.
It seems like one of the spots that is an issue is the passenger side dash air vent, although I am not sure just yet. Anyone else have anything coming from that area and has any tips!?
thanks!!

I have it.
When the cabin gets cool/cold it emerges. In the winter, before the cabin warms.....or in the summer when the A/C is on for a while.
The cold must cause something to contract and loosen? Same for you?
There were many threads mentioning a common B pillar rattle.

I have a noise coming from the passenger side when I'm on the highway. It sounds like something is flapping lightly in the wind against the car. Get worse the faster I drive. I haven't been able to get somebody to drive me while I sit in the passenger seat to pinpoint where it's coming from. I was waiting for my next service visit to have the dealer check it out.

Ok I drilled down a bit on this after work..it is 100% coming from the passenger air vent. Anyone know how to remove that piece. It can’t be hard but I don’t want to break any clips in the process. I will take to the dealer but the nearest is about an hour away...would have to wait until my oil change. Hoping to solve on my own in the mean time

Contrary to what I’ve read on these forums regarding rattles - I don’t believe that a car that develops rattles are “defective” here’s why: I brought my car to Lexus dealership last night for two rattles that I just don’t have the time to solve on my own. They put me in a brand new 2018 RX350 - 1,000 miles on it loaner vehicle. This thing has more rattles than you can imagine. Dash/Rear/Door..bottom line is - living in the northeast the roads are far from smooth as glass in most areas. Constant bumps just loosens these interiors up faster than say an IS out in LA..it’s a shame because it’s very annoying and makes the car sound cheap..hoping they can fix the few I have but definitely ready for the call saying “we can not replicate the issue” ..

Last thing I would want is the service people tearing the car apart. I need a patient person to sit in the passenger seat and try to isolate the source.
Unfortunately my GF doesn't have the patience or interest. I say...."do you hear that rattle?".....she says, "no, I think you are too obsessive regarding this car". :-)
The frustrating part is that it might be DIY fixable if I could isolate it. Anyway, I agree entirely that rattles are not defects. Terrible roads here as well.
I have all of the potholes/sunken manhole covers memorized for my DD. I also agree that it is the roads. Nice post!

That being said, if there's a constant or loud rattle, please do yourself a favor and get it fixed. I had a really bad one in the steering column. It started maybe 2-3 months into my time with my IS, which was brand new when I bought it. The dealership fixed that one, and it hasn't resurfaced since. All the other rattles I have are intermittent as mentioned above, and turning on the radio is enough to drown them out.

Mine is still pretty much brand new, 2018 IS300 bought a couple weeks back. It has this annoying little buzz/rattle on the driver side door when I play music with more bass... When I push my knee against the interior door handle area, the buzz goes away until I lift my foot off.

I fix all rattles myself using a roll of felt tape from ebay. Pop the suspected panels/trim pieces, and simply fold a piece of tape over the male end of the tab that holds the piece in. Then reinstall. I've silenced some pieces on my CT200h and it's rock solid. Not a peep. As years go on, things dont fit exactly as they did when new, so movement will cause things to make noise.
Can happen on new cars, too.

to be honest that sounds like an easy one. they can usually fix the ones that can be easily replicated. its the ones that are intermittent that are left behind 
and heres a tip you can show the dealer or for you if you fix on your own..there is an iPhone app called 'tone generator' - it will play specific bass tones, and keep it steady. you will find that in no time..

So I actually had a problem with the driver’s side having a vibration when playing music and I don’t even keep the bass that high. It sounded like it was coming from the between the door and dash. I took it to the dealership and it ended up being something about when they got the car ready for pickup for me some piece of tape or something had gotten stuck on the inside of the door or something like that and they just removed it and boom no more rattle.
