2008 Pontiac G8 Engine Problems

TL* THE CONTACT OWNS A 2008 PONTIAC G8. WHILE DRIVING 40 MPH, THE CHECK ENGINE INDICATOR ILLUMINATED. THE DEALER DIAGNOSED THAT THE TIMING CHAIN WAS STRETCHED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 94,000.

I AM INVESTIGATING A FIRE , THE CAUSE OF THE FIRE WAS A 2008 PONTIAC G4. AFTER THE OWNER DROVE THE CAR HE PARKED IT IN HIS GARAGE. WITHIN 20 MIN. OF PARKING THE CAR IT WAS ON FIRE IN HIS GARAGE. THE FIRE LOOKS TO HAVE STARTED IN THE ENGINE COMPARTMENT OF THE CAR. THIS FIRE BURNED HIS HOUSE DOWN AND INJURED HIM. I AM LOOKING FOR ANY INFORMATION THAT I COULD USE IN MY INVESTIGATION INVOLVING FIRES RELATED TO PONTIAC G4 2008 MODELS.. THIS INFORMATION WILL BE USED FOR FIRE DEPT USE IN CONFIRMING THE CAUSE AND BACKGROUND OF THE FIRE. ANY HELP WILL BE APPRECIATED. PLEASE EMAIL ME ANYTHING YOU MAY HAVE RELATED TO THIS MODEL CAR INVOLVED IN FIRES TO : [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

UPPER RADIATOR NECK SNAPPED OFF OF RADIATOR, ALLOWING UPPER RADIATOR HOSE TO SEPARATE FROM RADIATOR. ALL COOLANT ESCAPED CAUSING ENGINE TO IMMEDIATELY OVERHEAT. "ENGINE EXTREME OVERHEAT" LIGHT ON DASH CAME ON. GM SAYS NOT COVERED UNDER WARRANTY. THIS IS EVIDENTLY A COMMON PROBLEM WITH THESE CARS, AND THE SIMILAR 2004-2006 GTO AS EVIDENCED BY ALL THE THREADS ON THE SUBJECT ON GRRRR8.NET AND G8BOARD.NET. THIS SHOULD BE A RECALL. JUST GLAD THIS DID NOT HAPPEN ON THE HIGHWAY AS COOLANT BETWEEN THE TIRES AND THE ROAD WOULD HAVE CAUSED A MESSY WRECK. *TR

TL* THE CONTACT OWNS A 2008 PONTIAC G8. THE CONTACT STATED THAT WHILE DRIVING 50 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE FAILURE RECURRED TWICE. THE VEHICLE WAS TOWED TO THE DEALER FOR DIAGNOSIS, BUT THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 60,000. *TR

I WAS DRIVING DOWN 95 SOUTH NEAR BALTIMORE AT ABOUT 70MPH AT 7AM THIS MORNING WHEN MY 2008 PONTIAC G8 GT (WITH THE L76 6.0LV8 ENGINE) ALERTED ME THAT THE ENGINE WAS HOT. I IMMEDIATELY PULLED OVER AND WHEN I POPPED THE HOOD I SAW THE UPPER RADIATOR HOSE WAS NOT ATTACHED TO THE RADIATOR ANYMORE AND A LOT OF COOLANT HAD LEAKED EVERYWHERE. UPON CLOSER INSPECTION, I SAW THAT THE PASTIC RADIATOR FLANGE THAT THE HOSE ATTACHES TOO HAD BROKEN OFF OF THE RADIATOR AND WAS IN THE HOSE. SINCE THE ENGINE COOLING SYSTEM, WHICH I BELIEVE IS PART OF THE POWERTRAIN (GM WILL TRY AND TELL YOU OTHERWISE) WAS NO LONGER FUNCTIONING, I CLEARLY COULDN'T DRIVE ANYMORE, SO I WAS STRANDED ON THE SIDE OF A VERY BUSY 95. BEING STRANDED IS A SAFETY ISSUE, RIGHT? BESIDES THE IMMEDIATE WARNING LIGHT/ALARM, I HAD ABSOLUTELY NO PRIOR WARNING THAT THIS WAS GOING TO HAPPEN. IT WAS A SUDDEN AND UNEXPECTED INCIDENT. I DID NOT HEAR ANYTHING BEFORE HAND. I SAW NO STEAM FROM THE HOOD OR ANYTHING LIKE THAT. NOTHING. JUST THE IMMEDIATE WARNING LIGHT/ALARM. BESIDES AN OIL CHANGE AT ABOUT 62,000 MILES, I HAVE NOT HAD ANY OTHER SERVICES SINCE 50,000 MILES THAT WOULD HAVE TOUCHED THAT HOSE. I HAVE PICTURES OF THE HOSE AND THE BROKEN FLANGE AND I HAVE THE BROKEN PIECE OF FLANGE IN MY POSSESSION AND THE RADIATOR ASSEMBLY IS STILL IN MY CAR IF YOU'D LIKE TO SEE OR HAVE ANY OF THOSE PIECES. A QUICK SEARCH ON THE INTERNET SHOWS I'M NOT THE FIRST G8 OWNER TO HAVE THIS PROBLEM. THANK YOU FOR YOUR TIME AND I HOPE TO HEAR FROM YOU GUYS SOON! *TR
