Wiring problems of the 2015 Jeep Grand Cherokee

Service shifter message appeared at 62,000 miles upon starting engine and shifting into any gear or turning on cruise control. Will go away after approx. 5 seconds but occurs every time the car operates. Is not showing any error codes and appears to be a recurring issue for many owners and related to wiring harness and shifter.

Factory wiring harness, and any other harness for towing doesn't operate unless dealer programs to computer. . The cost is $135???. Factory installed trai. Er took up harness should already be activated. . No other make of vehicle requires this. . Why Jeeps. . ?? or our dealerships not informing and using it for a way to make more money? please investigate problem. . Owners need to be informed of this before purchasing vehicles. . Thank you.

Msg appearing service shifter, took into shop and stated it could be an electrical wiring but will not know until they break down the shifter. Jeep has already had a recall but I've already taken care of that recall on this Jeep. Reading a lot of people are having the same issue with the service shifter and really should be a recall on this. At this time I have a short to the circuit in the shifter.

On November 1st, 2015 my Jeep was rear ended while stopped at a red light. The other driver who hit my car admitted fault and is so documented in the police report. As of this date 2/3/16 the car is still at the repair shop. All repairs have been made except. . . The installation of a rear wiring harness that Jeep/Chrysler cannot provide. The estimated delivery of the wiring harness from Jeep is the end of March 2016. Chrysler customer care has refused to provide a rental car/make my payments/ or terminate the lease. My case # at Chrysler customer care is 28515506. I need help11.
