This is the best I've been able to do, and this seems to be a workable solution:

I entered the most common numbers that we dial into the car's memory, (about a dozen) and assigned names to them. I then initiate the call via the car itself, i.e. "Call House." It works flawlessly.

Still bizarre that it won't work when the call is initiated from the phone. This is a luxury automobile. Same exact phone works flawlessly with my Prius, and did the same with my Camry which I had previously.
