DEF Service Required See Dealer

New here guys & Need help. Have 2016 2500 w/ 6.7 displaying DEF Service message for the 3rd time in 6months. I've had it to the dealership the past 2 times, and the last time they said Fluid was bad. Charged me for a flush, clean, and fill, and had to change injector / other parts. I have put only 1 jug of Mopar DEF in since, and after 4k miles, got the message again today what gives ?? I'm doing a project in the mountains, and do a lot of really short trips, but don't leave truck idling at all. Once a week do a good run down the hill and back up..... Why is this a continuous issue ?? Please Help & thanks in advance.

Sounds like the Def pump is bad, that bad def is a go to statement from the dealers to take your money. If you put Mopar brand def in it and getting the message again....show them the receipt you bought it at the dealership
