I think, generally, automotive computers don't respond the same way to removing power as other consumer devices. The system detected an error and will keep telling you about it regardless of whether it lost power in between. If the problem that caused the error message does not re-occur, it will go away after 4 or 5 ON(Ready)/OFF cycles. I suggested this earlier as a way to determine how persistent the error is in a particular vehicle. However, others pointed out that you may not want to do that so the dealer will have more opportunities to see the error and the fact that you should not just clear the error and keep driving like nothing happened. You should take it in for repair at the earliest opportunity. My cynical side says that if the problem is not persistent, the dealer will just clear the error for you, update the firmware (that fixes unrelated issues) and give the car back to you anyway. Obviously I don't feel that's a sufficient "repair", if you can even call it that, but that's what people have reported.
