While driving on the interstate in Nevada (speed limit of 80MPH) I had my 2016 Suburban throw a rod through the engine block as I was in the left lane passing a Uhual on an incline. The vehicle made a loud bang, lost all engine power and protruded smoke so thick I could not see cars behind me. I was thankfully able to coast to side of the road without being hit. I then exited vehicle and there was a fire in the engine bay which I put out with a gallon of water in the trunk. My mechanic confirmed the thrown rod and hole in the block and that the car needs a new engine now. I had a CEL a few minutes prior to throwing the rod for an engine knock.
