Apparently, Chevy 2500 HD is known to have flaws with the def and NOx sensors. I'm not happy. I also have a cousin that had this same situation happen to him time and time again. Both of our engines reduced to 55 mph while driving in busy traffic on the highway. This is a safety hazard, to say the least. I'm not happy about this at all since parts and labor isn't cheap.
