2012 Ram 2500 Fuel System Diesel Electrical System Problems

I HAVE RECEIVED A NOTICE OF RECALL 2 TIMES SINCE DECEMBER 1,2014 FOR DIESEL FUEL HEATER ELECTRICAL CONNECTOR AND HAVE BEEN TO THE DODGE DEALER SEVERAL TIMES TO GET THIS TAKEN CARE OF. THE DEALER STATES THAT THEY DO NOT HAVE THE PARTS. THIS HAS BEEN OVER 8 MONTHS NOW AND I AM NOW EXPERIENCING ELECTRICAL PROBLEMS WITH THIS VEHICLE AS WELL AS WHAT APPEARS TO BE A STICKING THROTTLE AS I DRIVE. THIS IS A SERIOUS SITUATION AS THE VEHICLE DOES NOT SLOW DOWN WHEN RELEASING THE THROTTLE. IT ALSO AT IDLE WILL INCREASE THE RPM ON IT'S OWN. UPDATE 9/15/15*CW THE FUEL HEATER WAS FIXED. THE ELECTRICAL PROBLEM STILL EXISTS WITH HIGH IDLE AND THE VEHICLE ONLY SLOWED DOWN WHEN THE BRAKE WAS APPLIED. THE HIGH IDLE AND CONSTANT INSTANCES OF FAILURE OF THE VEHICLE TO SLOW DOWN WAS A RECURRING PROBLEM AS WELL AS THE INABILITY TO OBTAIN INFORMATION FROM THE VEHICLES INFORMATION PORT STILL EXISTS.
