I have several dtc codes u029d u029e p0420 p220b on three occasions. These code are triggering a limited speed and possible power reduction. The dealer ship states that GMC protocol is to replace one sensor at a time and let the customer go so they can breakdown again. The part that is failing I am told is the diesel particulate filter, but GMC can not supply the dealerships with the high demand. This seems like a faulty design that may work during the warranty period, but shorty fails after. I did report exhaust smell in the truck while driving . I was given a report and a large repair bill only to breakdown in 126 miles.
I bought my 2014 chevy k2500 durmax diesel 4x4 I bought it under the impression I was told it would get really good gas mileage and its horrible the salesman said the new requirements that gm done to the exhaust and fuel the gov. Required was to help on pollution and fuel mileage. This should be looked into the fuel economy is horrible.
