I was out of state when I had a transmission issue on my 2015 Sierra. It was a few thousand miles out of warranty, and the out-of-state dealer wasn’t able or willing to help me with cost sharing. When I got back to Minnesota, I contacted Randy at Valley GMC, which is the dealership that sold me the car. Randy went to bat for me and got a substantial cost sharing from GM on my behalf. This is in spite of them not even doing the repair - it was only to help a customer. I’m extremely impressed.
