Truck died. Lost dashboard functions, no engine crank, pcm failure. Had to have towed from side of expressway to dealership for diagnostic testing. Found out pcm was bad ,and had to replaced. Rarity, but coincidental when it happened just 217 miles over the 80,000 mile gm warranty time frame. It was almost a $800 bill that I had to fork out since there was no more warranty.
