I too have this sway bar problem! Had my 2005 Crossfire since new. Drive it very gently on our Australian roads which are not ideal (read rough!) suburban roads & certainly no "Dukes of Hazzard" driving from me! I've had 2 independent opinions, a mechanic & a panelbeater who both state that it is likely to be metal fatigue as it is not the bracket welds that have come adrift, but rather the bracket itself on the NSR that has fractured. The car has never been in an accident other than parking speed bumps!Both suggested I visit the dealer to remedy as it is in their opinion an original fault in manufacture. Took it to the dealer today & they rejected my claim that it be repaired under warranty . where to now I wonder?
