You said 6k until next change but how many since the last oil change? Seems when te DEF light happens around 6k past an oil change it means either they did not too off both tanks properly or the transfer pump is not working.

About 6K or 7K miles since the last oil change. Guessing that they didn't fill it properly last time. If it happens again, then it's something else.

6000 miles to go before oil service was due, but DEF warning came on. That was concurrent with the car needing a standard brake fluid service.

-- Re-filled DEF tank. Don't know why the timing was so far off from the oil service. They checked the system and everything was fine. Pulled in with 160 miles left.

Has to be one of 2 things. Either there is a problem with the DEF metering system injecting too much DEF, or it was not completely filled the last time (most likely).

I find it rather annoying no provisions are given to us to see roughly how much DEF is in the car. Annoys me since it is a required fluid for the car to run. To me it is like having no fuel level gauge but only a low on fuel warning.

Emissions recall probably addresses this.

Only if it is in fact the dealer not being bone heads and simply never filled things up completely during the prior oil change. It seems more times than not it is the dealer being bone heads and I doubt any recall is going to fix that. The secondary issue that seems to be a cause sometimes is the crystalizing of the fluid within the transfer pump, wonder if any recall could fully fix that or if it is a flaw to the very design of a two tank system.
