I did a quick search and didn't see this topic. If it has already been addressed, please point me in the right direction. I have a 2023 Limited 1500 and was driving in wet conditions at highway speed. I tried shifting from 2WD to 4WD Auto by pressing the button, and the 4WD auto button would flash and the 2WD button stayed lit. After a period of time, a message lit up stating " Serv 4WD". When I arrived at my destination, I did a quick youtube search to do a little research, since this was the first time I had tried changing from 2WD. The video stated that sometimes, you need to let off the fuel pedal so that it can perform the switch.
The next day, I was again in wet conditions so I thought I would try again. I pressed the 4WD auto button and let off the fuel pedal. The light continued to blink, then same error message. I tried it several times...releasing fuel pedal, putting it in neutral, putting it in park at a red light...it would never engage 4WD auto and the warning light would illuminate (it would go off after a period of time, though). Oh...initially a green message light saying 4WD would pop up, then disappear only to be replaced by warning light.
Any thoughts??
