DJVAN is correct. A service tech will definitely drive the car to see what's going on. There's no reason you can't go with him.
One thing that hasn't been mentioned yet in this thread is the "learning" software. The transmission software actually gets programed based on your first thirty or so days of driving habits. I don't see how this can work correctly, since a lot of families have two or three drivers. Does the software know which driver is using the car today? But I digress.
If the service people can't find anything wrong, ask them to reset the transmission software to factory specs. Make sure the ECON mode is off, and then drive the car around for another few weeks to see if the issue corrects itself. If it's fine for a week or so but returns, then climb over the service manager's desk, grab him by the throat, and demand a refund or different car 😀.
I have yet to hear a decent explanation as to how this learning software can work for all drivers. Perhaps it measures each drivers' habits, and then averages the numbers. To me, that would be stupid and meaningless. Nevertheless, give it a shot and let us know how it goes.
Edit
After your ride along with the service tech, if he says the car is behaving correctly, ask to take out another new Ody on the lot (if there is one). It doesn't have to be the exact trim level. It just needs to have the same engine and transmission, which I'm sure they all do now. From what you're saying, I can almost guarantee the second Ody will not act like yours. At that point, you have them where you want them. They'd need to explain why yours doesn't work right and the new one does.
