Scan showed c0398 code- transfer case control module- tsb outlines that if you have a c0398 code you've probably also had/have c0392 and c0396 codes, i believe. That might not always be the case. They checked for updates and cleared the code. They did cover it under warranty and it's currently in 2wd and working normally, however, I haven't tried switching between 2wd/4wd and I've left it in 2wd instead of awd. (Other post say to leave it in 2wd unless 4wd is needed then be sure to switch back to 2wd before turning truck off-so im trying that logic). This fixes it today, but isn't signed off as a permanent fix by dealer.

So, yesterday afternoon, I jump in my tuck after running errands. service notice flashes says "service 4wd" I dis miss this, check my 4wd knob and its in AWD, where it stays unless I need 4wd. I go to back up and turn and its clear Im in 4wd. Cannot get it out of 4wd. Tried running through 2wd/4hi/4lo etc. nothing no shifting at all. I drive a lot so my truck is at about 54K (its a 2015, bought in 2015) and I have had no issue with it so far. great truck. no complaints. So, I drive into town today, call the dealership (who at first said they couldn't look at it till Tues- wed) they eventually say they can squeeze me in today around 2. Great! I think this is great. Still under warranty, if it has to be messed up better now then in 6k more miles right!- but wait. looking up their warranty the most likely culprits (wiring, tccm etc) aren't covered under warranty. Really. with so many others having this problem?... I can accelerate and drive it, turns are irritating. Seeing that there aren't any real "fixes" for this since 2014 not a good start to this week. Anyone find anything that seems to have stopped this action from reoccurring?
