It finally happened to me today. Charging port refused to open. I had purposefully set it not to lock thinking that that would ward this issue off. Didn't help. Reset idrive, nothing. Restarted the app, unlock, lock, nothing. What did work was shutting off the permanent lock/unlock. I know it doesn't work for everyone. The other thing I noticed this evening, the car wouldn't unlock when I tried to get in it after a short drive with the key fob in my pocket. I had to press the fob. Not sure if it is related. But it has been acting flaky lately. I did a reset when I got back home.
