I assume this would apply to the Sierras and Yukons also?

I deal with this issue all the time on class 7&8 trucks. Glad to know it’s not just those trucks having this issue. One thought of what actually causes the failure is when DEF dries up it turn hard and is jamming up the sensor. I have yet to try cleaning one and see what happens.
