NHTSA Complaint #11647686 — 2019 GMC SIERRA 1500

I was driving down [XXX] near Harrisburg PA in an active construction zone when the truck shut off, the dash blinked a few things very rapidly then went black. I was barely able to coast to an area large enough to get my truck out of the highway traffic. I was stranded on the side of the highway for 4 hrs and due to the construction hardly able to get out of the truck safely as it was around a bend. I’ve had to have the truck towed to a few mechanics to learn that it has suffered a catastrophic engine failure as all cylinders have lost compression. It made no noise at all. There was no signs this was going to happen, just driving normally then a complete engine failure resulting in no compression in all 8 cylinders with no noise.
