Yes it is body flex but with also a noise when accelerating or stopping same as reported in above posts.

I just got my car back from the body shop and the squeaking is no longer happening in my 2018 LC. Here's the summary:

• I could hear a squeak from the rear of the vehicle, specifically on the passenger side.
• The body shop removed the back seats, removed the bolts from the cross-bar, applied squeak tape, then re-attached the bolts and tightened them according to the specs and order that was outlined here: https://www.lexusownersclub.co.uk/fo...lunking-noise/ (note they did not apply the grease and used squeak tape instead).
• They indicated this was the 3rd LC they fixed with this issue, and so far none have returned.
• The cost was over $900 for them to fix, which to me is quite excessive since it didn't seem like much work at all. I did shop around and very few places were willing to take on this work given most are inexperienced with this specific vehicle, so I was okay paying for their expertise instead of their time. I also had a very specific warranty on this vehicle when I purchased it (not CPO) which [thankfully] covered the cost of repairs.

If this squeak does return, I'll likely attempt the repair myself since I'm now much more educated on this than I was going into it.
