Major problems with my 2018 JL. Multiple warning messages. auto start, shifter, ABS, etc. steering loses power, wipers go off. I pull over and put it in park and can’t get it to shift back out unless I disconnect the ESS battery. It has been to the shop multiple times. Replaced main battery. Replaced ESS battery. Replaced PCM which was showing up when coded (112 fault code). Still doing it. Driver side floor area is pulling hot air from somewhere also. Help!
