NHTSA Complaint #11473745 — 2016 GMC CANYON

DEF Fluid/nox sensor. My truck has 37,000 miles on it. I have been limited to 65mph, 55mph, and then 5mph 3 separate times already because DEF fluid quality poor permanent code. It all comes down to a dirty nox sensor #2 in the exhaust. The DEF fluid is not actually poor quality. I frequently travel long distance. This permanent code should not be limiting my speed. I want a full recall and have this removed from the truck. I did not buy a truck for it to tell me I can't go a certain distance for so many miles because it may be polluting a little extra. This is a safety hazard and a costly hazard when you get stranded on the side of a highway or cannot keep up with traffic because the truck is limited to a certain speed. The message also blocks all digital functions from being accessed at all times.
