They just did the clamp/zip tie on mine and I'm doubting it will work, I have 750 miles on my 2014, yes you read that right 750, got so disgusted I parked it in my garage and left it sit. Going back this morning to have the B pillar trim panel replaced because it got scratched taking the seat out of the truck. Seriously tired of all the recalls over the years and I used to work at Delphi in Engineering so I had to answer the quality issues then from manufacturing but that is apparently a dead art. GM is turning a deaf ear to this stuff, I'm ready to buy a Honda Ridgeline. I have purchased 6 new trucks off of GM and I think this will be my last. No excuse for this problem to be all the way into the 2016 trucks and the fix I watched happen on my truck is a joke.If GM is reading this how about you offer to take this truck back?
The mechanic I have is excellent, dealership incredible, they all are trying very hard, GM is not and the only surveys I get are about the dealership which has nothing to do with design flaws. You have 6 sigma and Shanin red X experts on your staff perform a root cause analysis, look at your DFMEA and PFMEA and fix things!
