FDCM recall was applied and no working 4wd Low after. Service 4wd system warning. Still not resolved by the dealer - they are claiming it wasn't the reflash that caused the fault

Mine also started after recall flash. Took to dealer and they reflashed with new update fix. 4low worked in their parking lot. A month later went to use my boat and service light is back on. Taking to dealer again and see what they say. Hey jeep get your software updates right before telling people of recall. This is a second time chrysler has issued recalls to me and did not resolve problems without several trips to dealerships. I have owned jeeps for 30 years maybe its time to look elsewhere.

I ran the diagnostic by turning on and off the vehicle 3 times. When I turned it on the Jeep was now in 4wd Low and I couldn't get it out until I pressed something to put the transfer into neutral then again to get it back to regular driving mode.

Service 4wd light comes on randomly when trying to put it in 4wd low. If I pull fuse 33 in the fuse box closest to the drivers side firewall it resets it for a while and works fine until next winter then when I go to use it again the light comes on again
