I live in Northern Ontario. I have had Many issues regarding the DEF freezing in cold temperatures. My "check engine light" comes on, take the truck to dealership, they tell me that they update the computer with new program, few days later, same issue. It's been doing this now for 3 times.
The temperature is now closer to 0 degree C, and still doing the same.
Anyone out there with DEF system's issues?
