Honestly if you have time on your warranty do not even bother fixing it until it either gives in or your warranty is a few months from expiration, my car was driven 20k miles before the problem kicked in...

But if you must i believe all the crossfires produced march 2004 - september 2005 are on the recall list... there is a link through the chrysler site I think where you can check it through your vin number... it is posted somewhere on this site too just gotta spend a little time searching about the recall...
