- Today I will offer my rant about how unhappy I am with the LOW DEF notification on my 2021 GMC Denali with a 3.0 Diesel.
Without any earlier warning a screen popped up saying "DEF Empty Refill Now" and a screen sating "500 miles left to 65 MPH Max"
I am ok with a warning once in a while but GM has disabled any option to acknowledge and hide the warning screens. It takes over the main screen and does not allow you to see or adjust any other options until you fill it with DEF.
I believe it's an EPA thing that they can't let you dismiss the message if the DEF level is 0%. But I could be wrong about that.
If you actually never got the DEF low warning, which I think is either at a half gallon remaining or when it drops below 1k mile DEF range, I would be suspicious. Last time I was towing with mine (2020 LM2), I got the warning popup with ~850mi range. Put my back seat spare jug in at a rest stop and went on my way. If I was in your situation at the moment, I'd dump a 2.5g jug in it and take it into the dealer. There's a TSB (#22-NA-150) for all 2020+ 3.0's and 6.6's which is for a reductant control module recalibration. In this case, I would make sure to not completely fill the DEF tank since it seems like the TSB is hinting at the tech needing to add a gallon for and/or to verify the calibration. From what I've been reading and hearing, it sounds like the calibration issue could be giving false or no data at low tank levels. I haven't seen anything like this with mine, but honestly I've never let my DEF tank get to a gallon or less.
I bet if you put DEF in it that will go right away
It doesn’t go away after refilling. Already tried it
