"DEF low, but you know it's not" problem
We added DEF to our 2012 Chevy D/A before our last trip and off we went...Over 500 miles later we got notice that we had 300 miles until we added more...Didn't think that sounded right, but added anot...

at least on chevy, if your below 30% , you want to add enough to get it over 50% full, preferably completely full. Not sure what the issue is but that seems to be the best way to avoid problems.
But it's not just chevy with DEF issues. neighbor with a 2012 F250 was getting ready for a long trip, had DEF filled at the dealer, and just before he left, 9pm on a saturday up came the 'poor def quality" or some such message along with a restricted speed in 50 miles message. sound like something similar to BB_TX. Luckily the dealership was open, they ended up needing to do some kind of reset on the system to get him on the road.
