I don’t know how his turned out, but the exact same thing happened to my 2015 this week. Mine has 60,000 miles on it, but was still under the GMPP “Major Guard” plan for another year. Ask me what THAT was worth.? Had the truck towed to dealer($155.00), they said it was a “fluke”, reprogrammed it, and charged me $282.89!!!! Warranty didn’t cover it because no parts had to be changed?! When I asked how they know it won’t happen again...”it shouldn’t “....well, it “shouldn’t” have happened the first time!!!!!
