Last night I had a disturbing episode with my 2-month-old Model S. I had driven to a local restaurant for dinner, and had entered a free parking space uneventfully, but the moment that I pressed the "Park" button on the end of the shifter knob, an announcement appeared on the monitor that the car was in "Jack Mode," and that suspension leveling was disabled. Within "Settings," I tried to reset the suspension to "Standard" without luck (failure in doing this may have been my fault, due to not better understanding how the interface was intended to work). I went in to dinner, came back to the car, tried again unsuccessfully to get it out of Jack Mode. I decided to drive home, and started to back out of the parking spot when there was a dreadful scraping noise. Apparently the car had lowered itself, such that the bottom of the front now dragged over the low cement parking curb that the tire had been resting against. I called Tesla Roadside Assistance and reported the event. They confirmed that the car had entered Jack Mode at the time I reported, but stated that they had never seen a Tesla enter the mode on its own previously. By pressing on the brake and selecting "Standard" in the Suspension settings, I was now able to return the car to standard suspension. Roadside Assistance assured me that it was OK to drive home, which i did. They said they would be passing news of this event along to my local Service Center for further evaluation. I'm distressed that this may have left my vehicle with body damage (which I have to check for today in better light), another topic for discussion with Tesla. At the very least, this suggests that there should be a further warning if the car enters Jack Mode: "WARNING: the vehicle has lowered itself when entering this mode, so if it is parked at or near raised objects in the pavement, it may contact such objects if it is moved." Has anyone else has a similar experience with the car spontaneously entering Jack Mode?
