This is the 2nd day i've owned the X5 (I promise to get to the pics, i've just been busy driving

)and I got the "Trans Fail Safe Mode".
First I would like to say that my driveway has a slight incline. The nose of the X5 would be pointed higher than the back. As I pulled out of my driveway I noticed that the DSC icon (4x4!) in the middle of the instrument cluster wouldn't disappear. Pressed the DSC button and nothing happened. But I figured it was nothing and driving with DSC I guess wouldn't be a bad thing. I was stuck in some rush hour traffic and then when the road started to open up, the X5 seemed to have been stuck in gear (1st or 2nd), but it was revving really high. But I made it Costco (that's where we were heading), pulled into the parking lot and when I put the X5 in reverse, it kind of buckled. When I turned off the engine, the "Trans Fail Safe Mode" came on. While doing our shopping in Costco, i'll admit it had me worried that I might be stuck in Costco and I wouldn't hear the end of it from my wife. After we finished our errands, got into the X5 started her up, and everything went fine. The DSC icon was gone and so was the Trans Fail Safe Mode. The X5 drove home with no problems....
Reading that his seems to happen often, I hope it's just a minor bug. Please someone tell me something comforting...
