Finally picked the car up from the dealer today. It took an extra day because they needed to order one of the screw clips for the door. It definitely was not a low battery. The replacement door lock actuator is working as expected.
I can understand why this would happen at the temps mentioned in your thread, but it has not been below freezing here (rarely does it get that cold here) and it seems to happen below about 55F.
On the first cold (less than 50F) day here in Florida, my driver window would not do auto-down when I opened the door. My first thought was a door open sensor as the courtesy lighting would stay on after I locked the door. Took it to the dealership where I bought it. It was still doing it...
