Last night my wife noticed that her phone app came up with the message to the effect: "Summon failed. Charging cable plugged in." We were inside the house and did not summon the car. Had it not been plugged in, we might have found it in the middle of the street. When the summon app first came out a few days ago, we were seeing if both of our phones would get the option to summon the car. But it seemed that only one phone at a time could get this privilege. Could it be that the request was cached? I think I'm going to disable summon until I know I'm going to use it. I don't use the feature to park my car because I don't park symmetrically in the garage, so I don't like how it parks the car evenly between the other car and the other wall.
