So I'm having a hard time figuring this one out. At what seems like to be random times, I'll park my MS, get out, and come back several minutes later and find that the car is still "on" -- the radio is still playing, the dashboard is still up and running, the HVAC is running, etc. When this happens (the car stays "on") I can open and close the drivers' side door and it will immediately go "off". I had almost convinced myself that there was some algorithm that used a combination of putting the car in park, taking your foot off the brake, and opening the door that told the car to stay "on"... but I can't come up with any reliable way to gather enough data to figure out what's actually going on. Does anyone know what the inputs are that cause the car to stay "running" instead of turning itself "off"?
