I was told that it was a problem with the XCM module. But then again this was told to me by Dodge who just did 2 recalls on my durango and messed up my steering so it went back in to get fixed and they replaced the whole steering column as well as the broken part and now the recall that was done by them is no longer there so now I have to go get the recall for the shift lever block DONE again. But I do have that same issue with my service 4wd light being on with no code. It came on after I installed a new battery. ???
