2008 GMC ENVOY Unknown Or Other Problems

FIRE UNDER THE HOOD STARTED, ENTIRE CAR BURNED IN DRIVEWAY, DAMAGING HOUSE AND A SECOND CAR

MY VEHICLE JUST SUDDENLY STOPPED DEAD, IN THE ROAD AFTER LEAVING MY RESIDENCE AND ALL CONTROL WAS LOST. UNABLE TO PUT TRANSMISSION IN NEUTRAL TO PUSH VEHICLE OFF ROAD. I HAD IT REPAIRED BY A TRAINED MECHANIC AND WAS TOLD IT WAS A FAULTY IGNITION. I HAD THE FAULTY IGNITION REPLACED AND THE VEHICLE WAS OPERATIONAL AGAIN ALONG WITH THE WORRY OF THIS HAPPENING AGAIN.

02.05.2018 -- WAS AT A SUPERBOWL PARTY AND MY CAR WAS PARKED FOR 5 HOURS OUTSIDE, IT WAS ABOUT 20 DEGREES. HAD A 10 MINUTE DRIVE HOME - PARKED CAR IN GARAGE AND SHUT THE GARAGE DOOR. WHILE DRIVING, I DID USE REAR DEFROSTER AND WIPER BLADE, AS THERE WAS SNOW ON BACK WINDOW AND IT WAS SNOWING. APPROXIMATELY 15 MINUTES AFTER PARKING THE VEHICLE,I HEARD A LOUD BLAST, LIKE SOMEONE DROVE THROUGH MY GARAGE DOOR. THE REAR WINDOW OF MY GMC ENVOY EXPLODED INTO MANY PIECES. GLASS WAS INSIDE AND OUTSIDE THE VEHICLE. MY GARAGE IS NOT HEATED. I HAVE NO IDEA HOW IT HAPPENED. I CALLED MY INSURANCE COMPANY IMMEDIATELY AND AM GOING TO DRIVE THE CAR TO A GMC DEALERSHIP TO HAVE IT FIXED.

I WAS DRIVING THE SUV ON THE FREEWAY WHEN A FIRE STARTED UNDER THE HOOD. I CAME OFF THE FREEWAY AND WATCHED ENVOY BECOME COMPLETELY ENGULFED IN FLAMES AS FIRE DEPARTMENT WORK TO PUT IT OUT. VEHICLE COMPLETELY DESTROYED. NO KNOWN ISSUES WITH VEHICLE PRIOR TO ITS INFERNO MOMENT.

I PUT THE CAR IN PARK AND SHUT THE VEHICLE OFF AND PULLED THE KEY OUT OF THE IGNITION. THE CAR REMAINED RUNNING WITH THE KEY OUT AND IN ORDER TO SHUT IT OFF WE HAD TO POP THE HOOD AND PULL OUT A RELAY. WE THEN TRIED RESTARTING THE CAR AND IT STARTED WITH THE KEY TURNED BACKWARDS. IT WASN'T DRIVEABLE AT THIS TIME BECAUSE IT WAS SPITTING AND SPUTTERING. WE REPLACED THE IGNITION SWITCH AND IT WAS WORKING FOR A FEW DAYS AND NOW ITS BACK TO DOING THE SAME THING.
