Re: Electrical issues!!!
I've heard of a similar issure regarding a 2012 Jeep Grand Cherokee Overland Trim 5.7L V8 4x4. It started with wipers turning on and off intermittently, along with all dashborad lights, and front lights. Main recurring problem came up being that it was no communication between the CAN-C BUS, with open and shorted circuits between both the BCM, and PCM, voltages remained the same on certain nodes of communication, with the scan tool plugged in, it detected that all the modules in communication with the PCM were in fact in communication with the CAN-B BUS, and CAN-C BUS, same with BCM. But you would have to reset the scan tool to re-intialize communications with the CAN BUS. I haven't heard much more past that. Oh and the TIPM is not the brain, it is basically were all the fuses and relays are located. Lastly, a system reset is the absolute last thing the technicians at your dealership and the engineers at jeep in michigan would do, so don't worry, this would be the first issue they heard of.
