For the radar det. I was able to find a switched fuse on the driver side and using add-a-circuit fuse was able to power the radar




The Yellow circle is where i attatched for the ground

Default Tsib?

does anyone have the TSIB for this issue (or any other potential rattles??) I had a console rubbing/creaking where the console divider/handle meets the dash. They insulated that and mostly fixed. But now that I don’t hear that noise, I’m hearing a constant creaking and at times rattle like something is loose in the back. Also is anyone else’s passenger seat move? Not just the back but the whole seat moves and dealer keeps saying it’s not an issue. For a 120k car this thing is so loud. Don’t think I’ll ever buy a first model again. I got the RCF first model and had same issues. Think it takes a couple years for Lexus to make a vehicle quiet. So aggravating!

Glad you finally got your LC fixed! I'm taking my LC in tomorrow. Can you tell me if the sound that you were getting is the same as in my attached recording? You may need to turn the sound up. Also, I find that my iPhone replay of the sound (high-pitched) is more accurate than my PC speakers (low-pitched). Thanks!

I am in Dallas and have taken my LC back to the dealer four times now. Service has done many of the same "repairs" as others here with no resolution. Sound from glass roof keeps coming back. Anyone local or otherwise reach out to me so we can create awareness. Definitely not what I expected from Lexus!

All, thanks for sharing your experience! I read through the thread and i am going to be taking the LC in to address the squeaking/rubbing sound from the rear cabin. Want to confirm if anyone have been able to fix the issues with Lexus dealership, please share if you are successful.

would be be helpful if anyone knows if there are TSIBs for these issues. I don’t know how to access but also hate the mutille returns trying to get all these rattles resolved.

Default Slight Creak and Rattle from Glass Rooftop

I have the same issue with my LC500 Sport Package with the glass rooftop. I love my car so very much, yet this is the only complaint and disappointment I have. Does anyone know if there is a fix for this?

All,

Great news! The dealership actually fixed my squeaky noise issue! After taking apart of the back seats, they were able to locate the sound and it was from the cross support that is located underneath the thigh (the metal bar on the left of the picture below). They found the sound when the frame flex so they added insulation and tighten up a couple of bolts. So far so good! No more annoying squeaky sound. I thought the sound was high up but they checked the lining and the brake light and found no issues. Anyways, I am a very happy owner once again! Good luck with your fixes.




Cheers,
Steven

can you tell me how to? I think I have to do something with this plastic switch. Also where did you fuse tap into and ground? Thank you
did you run wires in front of the airbag? i wouldn't do that. for obvious reasons. there's much better places to pull power from then by running wires up the a pillar. i assume LCs come with a sunroof switch/map light assembly? if so, look there first w/ a multimeter

It has been 1k miles since last update. NO rattle !!!!!!!

Remove the coat hanger on both side


then there are 3 clips that will detach easily when pulling the ehadliner downward. one is center and the other 2 are on each side as shown below


the headliner is fitted to the other liner to the side. The liners will separate apart and will fit right back easily





Here is the clip in green




As you can see....No crease despite my multiple repair trials...


So I’ve tried all of these potential fixes (and more) but the cracking noise is still there. Anyone successful trying another procedure?

Mine is back at my Lexus dealer for the second time for the noise coming from the third brake light assembly. First time they fixed it it lasted four days..total quiet and then it returned. Not as loud as before but still noisy even over interstate speeds in the car. Dealer had TSB in the attempt to fix it initially.
