I’m betting it’s rather the front sway bar. There’s this handy-dandy TSB and RSU 22-210 that’s basically your go-to guide. It spills the beans on how to tighten that sway bar just right so you can fix the issue and get back on the road. Super straightforward!
I had similar issues with my 2023 WL S3 that were getting progressively worse. Look into TSB 09-010-23. They just took care of it, and it seems like everything’s back to normal now!
