Yes I had twice. Not error messages, but it would not boot any screen. Last time I had cabin preheat on via the app, still running. Unlocking the car and leaving something in it, but then not in time to remove the chargecable, as that was locked in again (short time for its release). Pressed the unlock button again on keyfob, and took out chargecable. Then it would not boot any screens. Needed to lock the car and unlock it again, then it was just as normal. Don't really think it was because of the preheat alone, but probably double-unlock with cable in, as I preheat all the time and doesn't get this error when unlocking only once.
