Had same issue last week on a 240 mile roundtrip. It went away after a sleep cycle(an hour or so) and then it came back again while coming back. I also saw the error "Transmission malfunction, do not change transmission position". I have an appointment with the service center later this week. Looks like it's the 12V battery fault. It happened twice after driving for couple of hours.
