So found thread to fix dashboard rattles but figured I'd call Lexus to see what they say about it. Was quoted $1100 to address issue by removing dashboard. After I said I'll do it myself, service advisor suggested putting some insulation between exterior plastic cowl that touches windshield. If you run your fingers along cowl edge against windshield, there's a gap in some spots. Stick insulation or double side tape in there. So here's what fixed my dashboard rattles and creaks.

1) Fill in exterior plastic cowl gaps between windshield with double sided tape.
2) Stuffed 3.5 ft x 6 inch black felt between dashboard and windshield. Carefully use tiny flat head screwdriver to tuck felt in. Stuff with more felt until full
3) Stuffed small pieces of felt where bottom of center console touches ashtray. Stuffed on each side of ashtray container, also see other spots circled red. Side leather where shifter is( very bottom red circles) have gaps underneath. If you push on it, it will also creak. Stuff with felt.

It works!!!

I'm going to try #2 with a towel first.

I can replicate my rattles simply by putting pressure on the dashboard. Sounds terrible in the morning. Sounds like the bed when you're having sex.

hopefully this holds up for everyone. This was so annoying to me when I had my GS.

Now it has been about 2 years.... so I can tell how the fix works on the long run... Stuffed the felt between windshield and dashboard - still works. Total amount of time spent? - 15-20 min. One thing though - you have to apply quite a pressure and yet be careful to really push it in until space is full AND not visible from outside.

I did this last night and what a difference. Today driving to work was the quietest my car has ever been. I had already pulled the nav and shifter console and put .25 inch foam on all possible rattle spots. This helped a bunch. But i still had noise from the dash. Thanks for the tip.

I poured a can of WD40 down all the seams in my dash, fixed it but my car smells horrible.



Lol, total joke...I need to do this to mine bad!!! I love my 430 but the dash squeaks are so annoying.
