This is a feature, forgot what is called, and it can be disabled in the settings menu. I was surprised by it also, as I have never seen it on any vehicle.I haven't figured this out yet, but maybe it's in the owners manual. There has been times when the car is sitting and locked and I walk by it with the key fob in my pocket and the outside lights come on (like when you lock it). Kind of weird and I haven't figured out the exact scenario when this happens.
If anyone has noticed these or has some additional things they have noticed, please respond. That way we have additional information if we take it to the dealer for service.
Something I have noticed with wireless apple car play. It was problematic until I disabled wifi hotspot in the car. Now car play has been much more reliable with connecting every time I start the car. I had an issue yesterday though where the volume wouldn't adjust up or down on any source. FM, NAV, car play etc, until i disconnected my phone an reconnected it. Seems like they still have some bugs to work out.
