Mine has done it about 5 times, always in reverse, when shifting quickly (never happened in any other car before to me). I took it to the dealer after the first few and they did something with the throttle body, I had a more serious transmission scare a couple of months later (I could only drive in 1st or 2nd gear and the check engine light came on )- I took it in and they did a computer update and fixed it, now it is stalling again in reverse.
All of this with only 4000 miles.
