WHILE THE TRUCK WAS UNATTENDED, SMOKE WAS OBSERVED BY A PASSER-BY WHO CALLED THE LOCAL FIRE DEPARTMENT. FIRE DEPT BROKE A WINDOW FOR ACCESS, EXTINGUISHED FIRE. HAULED VEHICLE AWAY FOR SAFEKEEPING. HAPPENED WHILE WE WERE AT A CONDO COMPLEX, VEHICLE PARKED FOR THE EVENING. HEAT INTENSITY AND MELTED PLASTIC INDICATED THAT FIRE OCCURRED IN CONSOLE AREA. VEHICLE WAS OFF, WE WERE ASLEEP, NOBODY HAD ACCESS TO INTERIOR OF VEHICLE. A PHONE CHARGER WAS PLUGGED IN, POSSIBLY ANOTHER CHARGER AS WELL.WE CONTACTED GM TO FILE A WARRANTY CLAIM. IT WAS DENIED, ACCORDING TO YVETTE YOUNG BECAUSE "GM COULD NOT DETERMINE THE CAUSE OF THE FIRE SO IT IS NOT OUR PROBLEM." GM DID THREE INVESTIGATIONS, ONE BY THE ADJUSTER, AND TWO MORE THAT INCLUDED A "DESTRUCTIVE INSPECTION." THIS WAS A TWO AND A HALF MONTH PROCESS. WE WERE NOTIFIED BY PHONE THAT THE CLAIM WAS DENIED AND THE LETTER THAT ARRIVED LAST WEEK IS ATTACHED. WE DON'T SMOKE, DID NOT HAVE ANYTHING COMBUSTIBLE IN OR NEAR THE AREA AND ARE CONCERNED THAT THE FIRE WAS RELATED TO THE CHARGERS. SOMETHING IN THAT VEHICLE ALLOWED THE CHARGERS TO OVERHEAT EVEN THOUGH THE TRUCK WAS OFF, IN OUR OPINION. OUR CONCERN IS THAT IF THIS HAD BEEN IN A GARAGE OR HAD PEOPLE BEEN IN THE VEHICLE, LIVES COULD HAVE BEEN LOST. VEHICLE HAD 12,000 MILES ON IT.PURCHASED NEW, NO OBVIOUS CAUSE FOR THIS EVENT. EVENT OCCURRED AT BAY POINT IN PANAMA CITY, FLORIDA.

MY HUSBAND WAS DRIVING OUR BRAND NEW DENALI WHICH HAS ONLY 3500 MILES ON IT. THE ENGINE COMPLETELY SHUT DOWN CROSSING A HIGHWAY WITH 55 MILES PER HOUR POSTING AND MY DAUGTHER OF 8 YEARS OLD WAS IN THE BACK SEAT. THE ENGINE AS I SAID COMPLETELY SHUT DOWN WITH NO INDICATOR LIGHTS OR WARNING AND MY HUSBAND WAS UNABLE TO STEER THE VEHICLE. IT STOPPED OFF THE SIDE OF THE ROAD BY MIRACLE AND ONSTAR WAS CALLED AND THE VEHICLE WAS TOWED TO THE CLOSEST GMAC DEALERSHIP. APPARENTLY THE FUEL INJECTOR PUMP WAS DEFECTIVE FROM THE FACTORY. THEN IT ALSO BLEW SHRAPNEL THROUGH THE WHOLE FUEL INJECTION SYSTEM AND DESTROYING AND ALL THE FUEL LINES AND PARTS TO IT. I AM VERY CONCERNED AS MY FAMILY WAS IN THE CAR AND THIS COULD HAVE CERTAINLY BEEN A HUGE TRAGEDY. I DON'T FEEL SAFE WITH THIS CAR AND I WANT A FULL REFUND FOR MY AUTOMOBILE.
