This 'vehicle sleep' happened to me multiple times yesterday, not in the morning but in the afternoon. Hadn't happened before. Car functioned absolutely perfectly this morning. Hoping that continues. Also, started to get the persistent (every 10 secs) 'key not detected,' which had only happened intermittently before. I have not had the SC visit yet for fob update although I am scheduled for next week. I texted one of the techs at the service center to ask if there was a way to turn off these alerts and got a mind-boggling answer. There is a slot in the console (toward the front of the tray, thought was for sunglasses) to put the fob, fits perfectly. No more issues on fey fob detection. Did I miss a post on the forum about this? This would have been excellent information to receive during vehicle orientation but SAs probably didn't know this either.
