Duramax Emissions issue?

Had to take my 2014 2500HD in today, engine light.. Onstar said emissions but not critical IE you can drive it. Dealer now says DEF tank issue and a sensor. $900 for the sensor, it is out of warranty, but DEF tank issue covered. Not a happy camper LOL 37,700 on the truck 2 months out of the 5 year 50K. Seems I have read about DEF Emissions issues before. Anyone else?
