LC500 spontaneous frame crack (or something else?)
can ya'll record this cracking sound and post a video up here?
i just wanna see if its the same as mine. Mine is basically a light clicking sound when the frame flexes, but with the top down I cant hear squat.
Seems like more of an issue with the coupe.

Has anyone attempted to tighten the bolts on the rear cross beam themselves? I know it requires removing some of the rear interior pieces to access the brace, but I'm thinking if I can do it myself, I can just re-tighten the bolts when they come loose instead of dealing with the body shop.
I've heard it's rather straightforward, so this could be a good option for me until a better fix is available...

Let us know how it goes. I may be following suit. Just noticed this in my 2024 Inspiration. I have a convertible though and it's more prevalent on the drivers side.
here is several verts which produce knocking noice on drivers side in top compartment area which is coming from close to the rear side window.
someone said that it was latching mechanism of the convertible top. I would agree because when I was trying to shake any moving parts I noticed that from driver side the locking mechanism was moving a little when I applied some little force and sound it was making almost exact same what I hear. On a passenger side nothing moves if I do same, so no sound.
coupes experiencing a different sound, more like a crack one.
could you describe a sound you hear. Is it more like dull knocking sound, and not like cracking one described above.

I finally figured out how to fix the rear squeaking noise myself and it took my just over an hour. It's also pretty easy to do, even for someone who's not very mechanically inclined - like me. Here's how I did it and the tools I used (it cost me about $30 with supplies left over):

If you do try it and figure out how to detach the wire from the rear seat belt, that would make this DIY even better and easier!

Given my research on this topic, it seems like this particular issue really only impacted 2018 and 2019 model years, which were all non-convertibles. You've got a newer convertible so I highly doubt you'll ever experience this particular issue!
