NHTSA Complaint #11714452 — 2025 RAM 2500

I have had my DEF system in my 2025 Ram 2500 Freeze twice now, I live in an area that drops below 12 degrees in the winter. I took it to the dealership the first time and they said the whole thing was frozen solid. I had to pay $365 since it is not covered under warranty for them to completely thaw it out and put new DEF in the tank. 7 days later it froze up again. The Service DEF System message seems to come on every time I have already been driving for awhile. I'm not trying to pay $365 every single time it freezes up.
