Another 5 MPG Max Speed in 150Mi Service DEF System See Dealer

So I got this message today "5 MPG Max Speed in 150Mi Service DEF System See Dealer"

No check engine light or any codes. Cleared codes anyway with two different scanners. Message is still there. I have the "Blue Driver" code reader and looks like one of the NOX sensors might not be working. Its reading 0.

Is it possible to clear this??

It's a 2013 with 26,000 miles. I'm over the 5 year warranty, so parts will be coming off if this isn't an easy reset. Tried to be a team player but enough is enough.
