Ever since this update my car is dead when I go to start it. I open the door and I get the "shutting down to save power" message. This is after I've been gone for hours. I've made an appointment to take the car to a dealer, the first available was in November. I've tried shutting down everything before I turn car off but this does not help. Everytime I see that message I know I'm going to have to jump start the car. Seems there might of been a bug in the update. Had the battery checked it is fine. Am I the only one having this problem??
