2010 Buick Lacrosse electrical system problems

I moved my car out of the driveway so my neighbor could plow our driveway. He said he smelled something. I parked the car across from our driveway put it in park, pushed the button to shut the car off, as my vehicle filled with smoke, I grabbed the door handle and jumped out. My neighbor ran to my vehicle telling me to disengage the hood, I complied. Flames jumped up and out from the passenger side of the car under the hood. He threw a lot of snow on the fire to extinguish the flame. We inhaled fumes.
