I have reported fobs not profile switching... Here's the pertinent back and forth with NA Service about this issue a few months back. The issue is still unresolved for me.
NA Service:
When you are approaching the car, are both Key Fobs going into the car or just the one Key Fob? As a work around, when approaching the car, pressing the lock or unlock from the Key Fob helps the vehicle to determine which KeyFob will be the driver and would change to the correct profile linked with it.
Me:
>> When approaching the car, only one Key Fob is in range most of the time. Almost always, the other is well away, in the middle of the house, far from the garage. I specifically tested them both separately this evening around 7:45pm PT. I do hear a motor actuate and the car does recognize both Key Fobs but no profile change is made. Only one Key Fob (#1) actuates a profile change (from "Wife's" to "Mine" when #1 approaches and the car is set to "Wife's'"). When #2 approaches and the car is set to "Mine", it does not enact a profile change, even with a Key Fob press. I did try removing and re-adding the Key Fob #2 to the profile but that's all I've tried so far.
