I have taken this vehicle back 5 times for the DEF problem. They have changed the tank and the sensor but the problem continues. The warning comes on saying I have 9XX miles left before required refill of the DEF tank. 10 miles down the road it says I have 11XX miles left. Next time I crank up it says I have 3XX miles left. 10 miles down the road it says I have 5XX miles left. 10 more miles and it says 4XX, 10 more miles it says 8XX miles, then it says My speed will be limited the next time I crank up. The next time I crank up it says I have 4XX miles left before refill. This goes on for a month or so and then without warning my truck is limited to 50MPH. I get constant engine light warnings and OnStar confirms DEF issues. I take it in, and within a month after, it starts over again.
