Yeah mine was stalling shifting into drive from reverse....hot or cold engine....and i don't throw it into drive like alot of people when you're still rollin 10mph in reverse....I STOP before I change gears. Started the stalling once, then like 2 days later it started it again and kept doing it. Couldn't feel or hear the RPM's dropping, but I could feel the steering lock up...which at first led me to believe the power steering pump had gone bad or something. I had an appointment the next day at the dealer anyways for a free oil change, so I mentioned to them. It was, and still is, under warranty, so any problems should be fixed with no issues. They kept it most of the morning, brought me home in their shuttle (I live 30-45 minutes away from my dealer), and came and picked me back up again, after calling me first to tell me what they found, and what their plans to "fix it" were. Afetr I gave them the go ahead, they sent the shuttle back out to get me again, and had it ready and waiting for me when I got there. All i had to do was go in and get my keys back and i was on my way. Very impressed with how the dealer treated me and the fact THEY ACTUALLY GOT IT FIXED RIGHT ON THE FIRST TRY!!!! I know its hard to believe for a DCX dealer, but they got it! This particular dealer has been around for about 80 years, so I think they know a thing or two by now...LOL.
You might run it by auto zone and see just for kicks if it is really throwing a code, and for some reason, not tripping the light to come on. Its all computerized, so it's very much possible. Autozone will scan it for free usually and if there is a problem, they'll tell you. Where as, the dealer, will more than likely chrage you a boatload to do the same thing.
Notice any funny noises as you notice the RPM's slowly dropping? Like squeeling or the alike?
