Actually, Cummins would be the BEST place to take it.
You have a 5 year, 50,000 miles warranty on DEF and Emissions related Cummins items.
The only issue we ever had was at about 25,000 miles when the 'engine outline' yellow alert came on, which is for EMISSIONS related problems. After FL and Cummins diagnosed it over the phone as a probably NoX sensor issue, they said to just keep driving until I could find time to schedule a visit, but not to worry about miles or speed since it would not derate the engine.
Cummins, in Fort Wayne, IN, did the service. I stayed overnight at their 50amp hookup, in their gated lot, and they drove it in first thing, and had the Nox sensor changed by mid-day.... never any issue since. Good people.

That's not accurate, the def tank heating element is heated off engine coolant and there are 3 sensors in the tank a temp sensor ,level sensor and a def quality sensor, when the tank temp sensor detects temp low enough to freeze it opens the electric valve on the top of tank and heats the def and pump and turns on the def line heaters,if ignored it will go into a mild derate at 25% power reduction for awhile and will then progress to whats called a scr driver induced derate with red and yellow check engine light and will limit speed to 5 mph.
So do not ignore this as you will end up paying a tow bill and freightliners 100+ dollar an hour repair as it can not be repaired on the road
