DEF reservoir got low and light came on indicating about 300 miles until truck goes into limp mode 5 MPH. Added 1 gallon of DEF and the guage showed to be in the safe zone. The computer system never registered that fluid was added and truck went into limp mode on the way home. When in limp mode you are unable to move vehicle off the roadway in a safe manner or even drive on any roadway without major risk of getting hit. Truck has to be towed to a dealership to have the computer reset. EXTREMELY DANGEROUS. Ironic that first responder and government vehicles with this same engine ect are omitted from the limp mode function due to safety concerns but not the general public.
