ONE DAY MY SUNROOF WORKED AND THE NEXT DAY IT WOULD NOT. IT WAS STUCK IN THE IN THE OPEN POSITION (NOT FULLY OPEN, BUT WHEN THE FRONT END RAISES AN INCH OR SO). I TOOK IT TO A GM CERTIFIED MECHANIC AND THEY SAID I WOULD NEED A WHOLE NEW ASSEMBLY AND QUOTED ME $2,100. THE DEALERSHIP AND GM NOTIFIED ME THAT THEY WOULD NOT HELP ME WITH THIS DEFECT AT ALL. MY CAR IS IN EXCELLENT CONDITION WITH ONLY 85,000 MILES ON IT, BUT IT IS ONLY WORTH $5,000 AND I PAID OVER $14,000 FOR IT IN 2009 WHEN I BOUGHT IT FROM A GM DEALERSHIP. I CANNOT AFFORD TO LOSE $2,100 ON THIS VEHICLE. AND THIS IS NOT THE FIRST ISSUE THAT I HAVE HAD. WHEN I DROVE IT HOME FROM THE DEALERSHIP THE WHOLE INSTRUMENT PANEL FAILED. THEY FIXED THAT. THEN A YEAR LATER, WHEN I WAS DRIVING HOME WITH MY NEW BORN, THE ENTIRE CAR SHUT DOWN WHILE IN MOTION GOING 45 MILES PER HOUR. THE DEALERSHIP SAID THAT IT WAS A PROBLEM WITH THE COMPUTER AND THE WARRANTY WOULD NOT COVER IT, BUT IT WOULD COVER A RESTORATION OF THE COMPUTER. THEN WHEN I WENT TO GET MY VEHICLE THE REFUSED TO LET ME TAKE IT UNTIL I PAID $200. MY VEHICLE HAS SHUT DOWN WHILE DRIVING SINCE THAT AND CAN BARELY MAINTAIN IDLING AT TRAFFIC LIGHTS AT TIMES. NOW BACK TO THE SUNROOF, AFTER NOT BEING ABLE TO AFFORD TO FIX IT THE MECHANIC TOOK OUT THE SUNROOF AND JUST SET IT IN THE FRAME SO AT LEAST WATER WOULD NOT GET IN WHEN IT RAINED. HOWEVER, IT IS JUST SITTING IN THERE AND CAN EASILY BE LIFTED OUT AND MAY EVEN GET BLOWN OUT ON THE FREEWAY. WHEN EXACTLY WILL THIS BECOME A SAFETY HAZARD? WHEN MY SUNROOF BLOWS OFF ON THE FREEWAY AND CAUSES A FATAL CAR ACCIDENT? OR WHEN MY CAR COMPLETELY SHUTS DOWN ON THE MIDDLE OF THE FREEWAY AND MY CHILDREN AND I GET KILLED IN A PILE UP? GM HAS BEEN CONVICTED OF NEGLECTING TO RECALL VEHICLES WITH SAFETY ISSUES RECENTLY. CLEARLY, GM REFUSES TO PROTECT ITS CUSTOMERS. PLEASE HELP PROTECT CONSUMERS AND DO SOMETHING ABOUT THIS.

ENGINE

I PURCHASED THE VEHICLE MARCH OF 2014 FROM SUNSET MOTORS IN COEUR D ALENE, ID. THE FOLLOWING DAY THE CAR DIED AND I TOOK IT BACK TO THE DEALER WHERE THEY TOLD ME THE FUEL PUMP NEEDED REPLACED; WHICH THEY REPLACED. I LEFT THE DEALERSHIP AFTER THE REPAIR WAS COMPLETED AND FILLED MY GAS TANK WHEN I BEGAN TO SMELL A STRONG ODOR OF GAS. I PULLED AWAY FROM THE PUMP AND LOOKED UNDER THE VEHICLE TO SEE GAS LEAKING FROM WHAT APPEARED TO BE THE FUEL TANK. I TOOK IT BACK TO THE DEALERSHIP AND THEY SAID THAT THE NECK OF THE GAS TANK WAS CRACKED AND THEY WOULD REPAIR IT. I LEFT WITH THE VEHICLE AFTER SUNSET MOTORS STATED THE REPAIR WAS DONE ON THE GAS TANK. THE CHECK ENGINE LIGHT CAME ON THE FOLLOWING DAY. THE CODE WAS READING P0455 LARGE EVAP LEAK. I HAVE TRIED REPLACING THE GAS CAP AS RECOMMENDED BY AUTOZONE WHERE I TOOK THE VEHICLE TO HAVE THE CODE READ. THE LIGHT CONTINUED TO COME ON OVER THE COURSE OF MONTHS. I RECENTLY TOOK IT TO AAMCO AFTER MY VEHICLE STARTED VIBRATING WHILE IN IDLE WHERE THEY INFORMED ME THAT THE CRACK IN THE NECK OF THE FUEL TANK WAS STILL APPARENT AND FUEL TANK NEEDED REPLACED. AFTER DOING RESEARCH I HAVE FOUND THIS IS A COMMON PROBLEM FOR THIS VEHICLE AND GM HAD OFFERED TO EXTEND THE WARRANTY WHEN RESEARCH INTO SAFETY WAS DONE PREVIOUSLY WHICH WAS ACCEPTED AND NO RECALL WAS DONE. GM HAS STATED THE WARRANTY HAS EXPIRED. I FEEL THAT THE LEAK IN THE NECK OF THE FUEL TANK IS A MANUFACTURES DEFECT AS THERE IS NO KNOWN REASON FOR A CRACK TO HAPPEN IN THE FUEL TANK. LIKE I SAID PREVIOUSLY I HAVE FOUND NUMEROUS REPORTS OF THIS HAPPENING TO OTHERS WITH THE SAME VEHICLE. I FEEL THAT IT IS A SAFETY CONCERN AND FEAR THE POSSIBILITIES OF WHAT COULD HAPPEN TO MY VEHICLE WITH MYSELF AND YOUNG CHILDREN IN THE VEHICLE UNTIL I AM ABLE TO AFFORD TO REPLACE THE FUEL TANK. I WOULD APPRECIATE THIS BEING LOOKED IN TO AND THE SAFETY AROUND THE DEFECT.

I PURCHASED A USED 2004 GMC ENVOY SLT, WITH AN EXTENDED WARRANTY FROM GRAND PRIX AUTO GROUP, HICKSVILLE, NY IN AUGUST 2008. SOON AFTER PURCHASING THE CAR IT STALLED WHILE WE WERE AT A RED LIGHT. IMMEDIATELY BROUGHT THE TRUCK BACK TO THE DEALER AND THEY SAID THEY FIXED IT, MAY I MENTION IT NEVER STOPPED STALLING. THEN THE SPEEDOMETER BROKE AGAIN. IT CONSTANTLY SAYS I'M TRAVELING 120 MILES AN HOUR. ONCE AGAIN, BROUGHT IT BACK TO THE DEALER, THEY TELL ME I NEED TO GO TO A GMC DEALER, I DO, THEY REPLACE THE INFORMATION CLUSTER AND SPEEDOMETER, HAD TO PAY A $ 300.00 DEDUCTIBLE. THIS WAS IN MARCH 2009. DRIVING THE OTHER DAY OCTOBER 2009 AND THE SPEEDOMETER ONCE AGAIN SAYS 120. GET PULLED OVER, GET A TICKET FOR A BROKEN SPEEDOMETER. THE OFFICER WAS AWARE I WAS NOT TRAVELING AT THAT SPEED, AND EVEN WHEN I TRIED TO EXPLAIN, WANTED TO HEAR NONE OF IT. SO NOW HERE I AM AGAIN, BROKEN SPEEDOMETER, ENGINE THAT STALLS OFTEN AND A SUMMONS TO BOOT. I NEED HELP AND I DON'T KNOW WHERE ELSE TO TURN THE DEALERSHIPS ARE OF NO HELP. JACQUELINE KING

ENGINE AND ENGINE COOLING

I WAS DRIVING IN TOWN AND MY SPEEDOMETER STOPPED WORKING AT 0. THE OIL GAUGE IS NOT WORKING, PEGGED OUT AT THE MAX AND MY ENGINE LIGHT IS NOW CONSTANTLY ON. THESE EVENTS, PARTICULARLY THE SPEEDOMETER NOT WORKING, IS A MAJOR SAFETY HAZARD. NOT DRIVING AT CONTROLLABLE SPEEDS CAN LEAD TO AN ACCIDENT AND DEATH. THE PARTS AND LABOR TO FIX THIS PROBLEM IS $550. WHILE RESEARCHING THIS PROBLEM ON THE INTERNET, I'VE FOUND OUT THAT THIS IS A COMMON PROBLEM WITH GMC'S IN THIS YEAR. THERE SHOULD BE A RECALL WITH THE CLUSTER UNIT ON 2004 GMC ENVOYS. GMC SHOULD TRY TO PREVENT DEATHS THAT THEIR PRODUCTS MAY CREATE.

ENGINE AND ENGINE COOLING:ENGINE

GMC ENVOY SUV (4.2) INLINE 6-CYLINDER. VEHICLE HAS STALLED FIVE TIMES INTERMITTENTLY OVER THE PAST SIX MONTHS. IT STALLS OUT WHEN YOU BEGIN TO STOP OR START TO ACCELERATE FROM A STOP OR JUST WHILE IDLING. LUCKILY IT HASN'T BEEN WHEN I WAS TRYING TO PASS OR MERGE IN TRAFFIC. THE FIRST TIME WAS AROUND 23,000 AND THE SECOND TIME 23,500. THE NEXT OCCURRENCE HAPPENED WHILE IT WAS SITTING IN A PARKING LOT IDLING AND IT DIED AFTER RUNNING FOR 5-8 MINUTES. I TOOK IT TO THE DEALER AND THEY SAID IT WAS THE THROTTLE BODY THAT NEEDED CLEANING - DONE. SIX WEEKS LATER AND 1500 MILES IT STALLED WHEN I WAS TRYING TO MAKE A U-TURN IN ST. PETERSBURG AND I NEARLY GOT REAR ENDED. DEALER KEPT IT TWO DAYS AND DID NOTHING SINCE THEY COULDN'T DUPLICATE PROBLEM AND COULDN'T GET ANYTHING FROM THE COMPUTER. I TOOK IT BACK TO THE DEALER ON 7/21 FOR REGULAR MAINTENANCE (OIL CHANGE, FUEL FILTER CHANGE, AND A/C REPAIR-BAD CLUTCH). THE DEALER SAID THEY HAD TWO COMPUTER MODULE UPDATES, ONE TO FIX STALLS. THREE DAYS LATER IT STALLED IN JACKSONVILLE TRAFFIC AT A STOP LIGHT. I HAVE TAKEN IT BACK FOR A FOURTH TIME TO THE DEALER AND LEFT FOR A WEEK. DEALER SAID VEHICLE IDLING ROUGH BUT COMPUTER NOT REGISTERING PROBLEM SO NOTHING WAS DONE, AGAIN. I E-MAILED GM AND I HAVE HAD NO REPLY IN TWO WEEKS. I SEE WHERE A PERSON WITH A V8 VERSION IS HAVING THE SAME PROBLEM. THIS IS AN ACCIDENT WAITING TO HAPPEN.

ENGINE AND ENGINE COOLING:ENGINE

I BOUGHT MY GMC ENVOY IN JANUARY 2004 FOR APPROX. $42,000. THIS CAR HAS EVERYTHING. AFTER ABOUT 2 MONTHS OF THE PURCHASE, MY GPS WENT OUT AND HAD BEEN FIXED TWICE. MY BRAKES DO NOT ALWAYS WORK --SOMETIMES THEY SLIP ESPECIALLY WHEN I NEED THEM MOST -WHICH IS SCARY. GMC SAID THAT THEY HAVE HEARD ABOUT THIS PROBLEM BEFORE, BUT DID NOTHING TO RESOLVE THE PROBLEM. THE ENGINE STALLS PERIODICALLY. GMC SAID THEY DO NOT KNOW WHY. THE GAS GAUGE AND ODOMETER DO NOT WORK PROPERLY. WHEN I BROUGHT MY VEHICLE INTO NORTH COUNTY GMC DEALERSHIP IN SAN DIEGO FOR REPAIRS I MENTIONED MY GAS GAUGE DID NOT WORK ALONG WITH MANY OF THE OTHER ISSUES. AFTER THEY REPAIRED THE ODOMETER BY REPLACING THE CLUSTER, THE GAS GAUGE STILL DID NOT WORK. EVERY SINGLE TIME THESE PROBLEMS HAPPEN I AM FORCED TO PAY A $100 SERVICE CHARGE JUST SO THEY CAN LOOK AT IT AND BECAUSE I AM IN SALES, I AM ALSO FORCED TO GET A RENTAL CAR. AFTER ALL THIS, I AM STILL QUITE DISPLEASED WITH GMC. I HATE TO SAY IT BUT THEY ARE SUPPOSED TO BE THE BEST AMERICAN CAR ??PROFESSIONAL GRADE?? AND IF THIS IS TRUE I WILL NEVER BUY AN AMERICAN VEHICLE AGAIN. GMC SAID THEY WOULD BE CHECKING ON ALL THESE PROBLEMS AND EVERY SINGLE TIME I PICKED MY ENVOY UP AFTER THEY SUPPOSEDLY FIXED THE PROBLEMS, I FOUND SEVERAL ISSUES STILL UNRESOLVED. THEY SUGGEST I NEED TO SET ANOTHER MEETING TO BRING MY ENVOY IN AND OF COURSE WILL COST ANOTHER $100.

FIRST OF ALL MY ODOMETER GAUGE STOPPED OPERATING. IT REMAINED ON ZERO MILES WHILE I WAS DRIVING THE VEHICLE SINCE NOVEMBER 2005. THE WHOLE DASHBOARD CLUSTER HAD TO BE REINSTALLED. SECONDLY; THE SERVICE ENGINE SOON LIGHT BEGAN POPPING ON AND THE ENVOY WAS DRIVING ROUGH. I FOUND OUT FROM A GM DEALER THAT THE CLUTCH FAN FROZE WHICH CAUSED THE WATER PUMP TO BREAK AND THE RADIATOR TO OVER HEAT BURST THE RADIATOR HOSE AND SPEW OUT AND LEAK ALL OF THE WATER AND RADIATOR FLUID FROM THE RADIATOR. THE ENVOY IS NOW NOT DRIVABLE. I HAVE ONLY HAD THIS 2004 ENVOY SINCE NOVEMBER OF 2003.
