While I was driving on the NJ Turnpike near Newark, NJ, I saw black smoke coming in the front windows that I had open about 3 inches each. I immediately pulled into the shoulder of the highway and turned the cars ignition off. By the time I got the car in Park and turned it off the entire front cabin of the car was so thick with smoke that I couldnât see or breathe. I was able to get out and away from the vehicle just as it completely went up in flames. Two truck drivers stopped and emptied their fire extinguishers on the fire but it did not help at all.

Prior to seeing the smoke, I had no warning lights on my dashboard, the temperature of the car never rose, and there were no emergency messages whatsoever. There also had not been any work performed on the car for at least 3 weeks prior to fire. Had I not been in a location where there was an accessible shoulder I donât know that I would have been able to get out in time to escape being overcome by the thick smoke. I have no idea what caused the smoke and ensuing fire and I also have no idea if anyone has inspected the vehicle since the fire.

They also knew that I had a courier service and us
