NHTSA Complaint #10670446 — 2011 VOLKSWAGEN JETTA

I HAD DRIVEN THE CAR EARLIER THAT DAY (ABOUT 40 MILES) WITH NO PROBLEMS. I GOT HOME AT ABOUT 7:30PM AND PARKED THE CAR OUTSIDE OUR HOUSE. AT ABOUT 2AM, I HEARD A BEEPING CAR HORN. I LOOKED OUTSIDE AND SAW FLAMES COMING OUT OF THE FRONT DRIVERS SIDE OF OUR BEAUTIFUL 2011 JETTA SPORTWAGEN. I DIALED 911, THE CAR CONTINUED TO BURN UNTIL THE FIRE DEPT ARRIVED AND PUT IT OUT. THE CAR IS A TOTAL LOSS. I'M ONLY HAPPY IT WASN'T PARKED INSIDE A GARAGE WHERE THE FIRE WOULD HAVE DESTROYED OUR HOUSE AS WELL. NO WORK HAD BEEN DONE ON THE CAR RECENTLY AND NO AFTERMARKET OPTIONS WERE INSTALLED. I HAVE ONLY ONE QUESTION - WHAT COULD CAUSE A COMPLETELY COLD CAR (NOT DRIVEN IN OVER 6 HOURS) TO SUDDENLY BURST INTO FLAME?? THANK YOU.
