4 Engine And Engine Cooling problem

Failure Date: 05/11/2022

This was in a rental from national car rental from the las vegas airport. I was driving down the road at about 65-70 mph when the vehicle's brakes just slammed on, and everything about the car just died. There was a huge groaning sound as it happened - kind of like when you are in 'park' and push the gas pedal and it revs really high. I tried shifting into neutral, nothing changed, and all the lights and functions of the car went out. I did my best to "direct" (couldn't steer) the car to the edge of the road. It was a busy remote highway, I was in the 'fast' lane. So could move over as far as I could to the other side of the white line while basically groaning to a halt. When I stopped all of the power shut down, the car would not restart and at first the battery and "service engine now" lights came off, then everything stopped. After a bit the battery came back on so I could at least charge my phone to use it to call for assistance. I have an email from national saying it appeared to be an engine malfunction. When this happened I was on highway 93 between las vegas and kingman arizona (right around mile marker 30). It is a split highway with a dirt median. I was on the inside of the median. Fortunately when it happened there was no one directly behind me or they would have hit me. This is the main thoroughfare between nv and northern az here, so it is basically semi trucks going >70 mph the whole stretch. I had to sit in the car for 2 hours waiting for the tow truck to arrive. I did not get out of the car because I was more scared of distracting a driver and veering into me, whereas sitting in the car I was just as scared, but I thought at least I had an airbag if I was crashed into. I was honestly terrified the whole time. I sent numerous emails and made numerous calls that document all of this. I have pictures and video of the situation. The car was picked up by jone's towing from kingman az.
