This little white push switch that fits over the 10 A Electrics fuse comes to the dealer in the off position, they then push it in on delivery. It prevents battery drain during storage as the name would suggest by disabling certain systems.

I started getting symptoms where the Homelink would stop working and the exterior chime also stopped, also my OBD II port stopped supplying power. Everything else functioned fine.

I checked the fuses and none were blown, however after more poking around I noticed that what I now know is the extended storage switch was wiggly, I gave it a good push in and it clicked, and all my problems went away. A week of intermittent problems solved, I was about to head to the dealer.
