Hello everyone! I'm new to this forum and hope you all are doing good. I am having problem's with my 2011 1500 Ram Bighorn. Every once in awhile, I get the Service 4WD alert. It won't let me shift out of park. I can turn the truck off and it goes away after I restart it. It has also happens, while I was driving. Doesn't effect the driving though. Has anybody had these issues before?
