If you have already paid to have the front brakes serviced, contact Chrysler Customer Service and open a case number. Then submit (fax) a copy of your service repair order and the manner in which you paid (credit card receipt/check/cash receipt) and they will reimburse you.
I had our "old" '09 front pads replaced in July of 2009 (we bought in March 2008) at 22K miles. I recently learned Chrysler would reimburse you if the repairs had to be done under 36K miles. I submitted my claim in January 2011 and within a week received a check for the full amount of the repair.
