NHTSA Complaint #11709096 — 2020 GMC YUKON XL

I was traveling along i80 and suddenly the vehicle shutdown. I put the transmission in Neutral and coasted to a stop. Once stopped, I check It would not start or even turnover at that point. I still had all electrical services and such. The vehicle. I was stranded on i80. Then had to be towed to the nearest GM Dealer in Evanston Wyoming. Heritage Chevrolet GMC. It was left there for diagnosis where their technician, several days later diagnosed it with a bad engine. There was no warning or check engine light that appeared. I even have a picture from a little while earlier while driving earlier that morning. It took it because I was surprised it was getting 28mpg in v8 mode. but I am glad I had that photo to show no diagnostic lights were on.
