MY 2013 GMC ARCARDIA SLT MODEL BURST INTO FLAMES ON ITS OWN ON THE MORNING OF FRIDAY, JULY 17TH. I CAME HOME AROUND 9:45PM AND PARKED MY SUV IN THE BACKYARD. THE NEXT THING I KNOW IS THAT THE FIRE DEPARTMENT WAS AT MY DOOR WAKING ME UP TO THE SUV ABLAZE. THE ONLY WORK THAT WAS DONE TO MY VEHICLE WAS TO HAVE MY OIL CHANGE THAT THURSDAY MORNING. AT WHICH TIME THE TECH SAID HE SAW SMOKE AND SMELLED GAS. HE DIDN'T INDICATE THAT IT WAS A PROBLEM AND ZI SHOULD GET IT CHECKED. I TOOK SUV AND RAN MY ERRANDS AND RETURNED HOME. THE SUV WAS PARKED FROM 9:45PM UNTIL SAID FIRE.
