We got our Model S exactly four weeks ago to the day. Today we got a warning signal that read "12V battery needs servicing" and below that "Replace 12V battery soon". Has anyone else gotten this warning? Can I drive the car with this warning on? I'm not sure what even runs on the 12V battery. I called service but they couldn't help me until tomorrow morning.:frown: It sounded like they are going to want me to make the drive down to the Fremont or San Mateo service centers to get it replaced, which I'm none to happy about. That can be over an hour each way plus the time for the repair and that is a huge chunk of my day. I really hope they send a ranger, or I'm not going to be too happy.
