I have a 2019 Ram Bighorn crew cab 4x4 hemi no electric backup or e torque whatever that is. Any way parked truck went to leave truck was dead. Fobs would not unlock doors tailgate would not open. Message in center said press brake push start nothing nothing. First thought dead battery. Put new battery in nothing. Maybe fobs are dead. New batteries nothing. Well read how to put in neutral pulled that lever nothing. Rear wheels locked will not roll. Had to call local dealer asked if he knew anything I could try and he had never heard of such a thing said truck needed to be there. Called a roll back they came tried everything they knew and nothing. Pulled lever to unlock tranny and nothing. Pulled my truck dragging tires onto roll back. Does anybody have any idea what the problem is? Also would manually lock doors and when I shut the door horn beeps 3 times and door unlocks.
