I have a 2011 2500HD, Duramax LML 33K miles and I am afraid to leave town in it.
The def errors keep happening over and over and will leave me stranded. A "poor def fluid" and others will only give you 200 miles to get it repaired or shut you down to 4mph.
I retired after working 41 years with plans to take this truck and my little Airstream trailer and fly fish every fishing stream in the USA but now I stuck with a truck that is for sure going to break at any given moment, 4 times now.
The last time I only made it 189 miles between repairs, just got it out of the dealership yesterday (1/6/2015) after 8 days.
It has also left me stranded in Mountain Home Arkansas with low def error when the def was full. That took two days to repair (great dealership there) but I paid too much for this vehicle to have to put up with this.
It doesn't take very long on google to see that these def problems are running rampant and have been for a very long time. Had I only know this before I bought this truck I wouldn't be here now.
What is GM doing to fix this problem and I don't mean a piece-by-piece change out until my warranty is out then say SORRY??
