2020 Mercedes-Benz GLE 350 engine problems

When my wife got into vehicle first thing in the morning after it sitting all night in the garage, she smelled a foul smell. As she was driving, she opened all the windows to dissipate the smell and turned in the heater because wit was cold that morning. After about ten to twelve minutes of driving, she noticed the check engine light came on and the car started shaking. She pulled over and exited vehicle. As soon as she got out the vehicle started smoking and caught fire. The vehicle is a total loss.
