So my 2015 2LT crew cab is back in the shop today for the 4th time. So far they have replaced factory SRA tires with Continentals, replaced an out of balance drive shaft, replaced the ring and pinion, and today they stated they were going to adjust the angle of the ring and pinion as suggested by GM engineer. They state the next step would be for the GM Engineer to actually come in and look at/work on it himself......I am very fustrated. They put me in a 2016 model 1LT model 4x4 and it rides terrific.
How do I start a buyback process? Who at GM do I need to talk too? Do I have to go through the BBB process?
