I took this from a previous thread regarding the recalls:
THE TRAILER TOW LIGHTING CONTROL MODULE MAY MALFUNCTION DUE TO A SOFTWARE ERROR. THIS COULD RESULT IN INOPERATIVE TRAILER BRAKE LIGHTS. TOWING A TRAILER WITH INOPERATIVE BRAKE LIGHTS COULD CAUSE A CRASH.
THE CAN-C BUS COMMUNICATION CONNECTOR MAY DEVELOP INTERNAL CONNECTOR PIN CORROSION DUE TO MOISTURE. CORRODED CAN-C BUS COMMUNICATION CONNECTOR PIN(S) COULD LEAD TO A LOSS OF ELECTRICAL CONTACT AND/OR A LOSS OF COMMUNICATION TO THE TRANSMISSION CONTROL MODULE (TCM). A LOSS OF COMMUNICATION TO THE TCM COULD CAUSE THE TRANSMISSION TO PERFORM AN UNREQUESTED SHIFT INTO NEUTRAL. THE VEHICLE OPERATOR WOULD BE UNABLE TO REENGAGE THE TRANSMISSION. THIS COULD CAUSE A CRASH WITHOUT WARNING.
According to my service department, the replacement connector is in short supply, so FCA is currently allotting them out to areas. Directions to them is if the part is in good condition and doesn't need to be replaced, then to just proceed with the relocation of the connector.
I had the recalls done on my 2015 PMC...did not need to replace the CAN-C BUS Connector as it was still in good condition, service dept. just simply relocated it.
didn't need the other recall, as I do not have a tow hitch, and then they did some required flashes to the vehicle software. Other than the fact that 1) the tech working on my PMC didn't close my hood all the way and, 2) he didn't tighten down the positive battery terminal, leading to me dying out in the middle of traffic....

I grow more and more disenchanted with my service department after every visit...
Other than that, my PMC is awesome!!!
