I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

I've been noticing a strange rattling sound from the adaptive suspension but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.
