I made appointment online at Hadadd Dodge to repair this. They said they could only order 1 set if parts per week and they have to repair the trucks on the lot first then will get to us. They canceled the appointment and put us on a waiting list. I made them aware we tow a 5th wheel trailer frequently with this truck.

Trucks DEF Gauge malfunctioning goes from full, to half, to full, to empty, and then warns about going into limp mode. Filled with DEF and still doing it. Took in for repairs, company said they fixed it, but within 3 miles gauge was doing the same thing. This is a hazard as it will put the truck in limp mode. Known issue with many complaints, needs fixed
