My 2007 Sebring has a real bad rattle when driven on rough snowy roads and I mean real bad. Had it in twice for diagnosis at a Chrysler shop but they don't seem to be able find the problem. To me it sounds like a bad strut. The dealership refuses to change it saying it's not the strut. I know of another situation where they had the same rattle from there car and a new strut fixed it. Anyone else had a problem this? Note this is my 9th. Chrysler vehicle and may damn well be my last.
