I was evacuating the Colorado Marshall Fires and my 2020 Grand Jeep Cherokee with 20,000 miles just quit while driving down the road. It was slow moving traffic out of the area with 100 MPH winds, heavy smoke and debris flying through the air. As I tried to restart it, there was a message about some sensor, but unclear as to what exactly the message was. The engine would not turn over. The car was partially blocking traffic and caught on fire approximately 10 minutes after it stopped. Those evacuating were down to one lane and navigating around a burning car. No investigation is possible as it is completed burned up. I have followed all of the manufacturer's recommended maintenance schedules and have had zero incidents with this Jeep prior to this. I would like some sort of investigation as to the cause (an assessment of the situation as there is no car left to inspect). I do not want this happening to another person/family as they are trying to get out of a dangerous situation. I was lucky in that there were others evacuating, however, had I been in an isolated area, my dogs and I could have been dead.
