I have a 2012 Sonata Hybrid with 66,000 miles. My wife told me the car was making a clunking noise! After inspection I fond the attachment point for the rear sway bar on the drivers side was broken off the frame. It appears the top bolt broke and then the bottom rocked back and forth until the tab on the frame broke off. Anyone have this issue? Not cool, can't wait to hear how this is going to get fixed.
