I have a 2012 V6, 30,000 miles, bought used a year ago. Thought there was something loose in trunk, but now, after taking into dealer, it was the sway bar bushings/ end links. Fixed under warranty. Another thing I asked was why the drive shaft linkage makes a thunking noise, just as I come to a stop and transmission downshifts to first (auto trans
). They said they didn't notice anything abnormal. Anyone have an opinion on that?
