It was definitely stuck in awd, soon as I enabled tcsm or similar name and put it in gear it immediately went back in 2 wheel. It also screwed my Paddle shifters up, they would hang in gear and drop back to drive and only goto gear 5 if I got it that far. Scanning back through settings Paddle shifters was no longer set to anything so I turned them back on but haven't tested them. My performance pages are working fine now without vehicle set to srt. Out of town but I'll play more when I get back.
I have a 2014 JV with AWD, updated the pages using a cheap scan tool and the app, but never had the AWD get stuck in the on position. Are you sure it is stuck? I've had the AWD come on at times when it didn't seem necessary at all, but it eventually shuts off.
FWIW, if you inevitably have to visit the dealer to fix this and still have a warranty, don't sweat having the pages enabled. My radio went tits up and when they replaced it under warranty, the SRT pages were still there. So they not only saw that I had them activated, they went ahead and re-activated them on my new head unit. Definitely not a problem, warranty wise.
One thing I have never been able to do is to get the dash panel display to show SRT as in the photos. Tried all kinds of combos with the app, to no avail.
