Previously was about 200 miles per gallon now upwards of 1000 miles a gallon. With and without a load.

My problem seems to have been fixed? since I had the def tank replaced. They did it because I kept complaining about it and after a lot of screaming and several trips to the dealer after the gauges kept freaking out they said it was per customer request. Night and day difference all around. Def usage is where it is supposed to be and gas mileage has improved. Thinking they may have thrown in a update also but nothing was said to me.

When the sensor went it would go all over the place. Full, half full 160 miles down to none at all while in park. Took 2 trips to the dealership to get them to realize that it was reading full and there was one gallon of def in the tank.

Slightly different because I actually am on my second part being replaced in 10k miles. At 2k I noticed a burning smell and smoke under my hood. Took it in. They said it was a ceramic coating burning off. I accepted this. 5k miles later I take my trailer on a 3k mile trip. At the end of the trip engine light comes on. Its the PPF. Packed full of carbon. Dealership said it was the smell and smoke from the issues at 2k. Had it replaced. Blue def usage is tops at 300 miles a gallon. Its now in the shop because the blue def float sensor is bad and was false reading and putting the truck into limp mode. GM is repairing that without a code. From what I read people have been getting 1k miles a gallon out of this model. Mine is just one exhaust issue after another.
