Had vehicle in for service four times for same condition, dealer has updated software multiple flashes, replaced DCM (Drive Control Module), Check Engine light comes back on within 24-48 hours. When this happens the auto start functionality and the selectable drive mode of the vehicle are no working. Vehicle running temp, idle speeds, shift points, oil pressures all running within normal range. This appears to be a communications issue with the time requirements over the CANBUS network? Really becoming a problem - due to no 4x4 lock in winter driving conditions! Any tech support from FCA Engineering would be great as dealership service techs seem lost.
