2003 GMC Envoy Engine Problems

WHILE DRIVING THE VEHICLE A STRONG ODOR OF GAS ENTERING THE CABIN. FILL VEHICLE UP AND LARGE AMOUNT OF GAS POURS ON THE GROUND FROM UNDER THE VEHICLE. CLOSER INSPECTION REVEALS THE PART THAT ATTACHES TO THE GAS TANK IS BROKEN OFF CAUSING VAPORS TO ESCAPE AND NOT PROVIDING A SEAL TO CONTAIN THE SMELL. WHILE DRIVING ON THE INTERSTATE AT NORMAL OPERATING SPEED VEHICLE LOSES OIL PRESSURE CAUSING IT TO DROP TO 0 AND MESSAGE APPEARS TO STOP ENGINE. BOTH INCIDENTS ARE SAFETY HAZARDS AND CAN CAUSE SERIOUS LIFE AN DEATH INCIDENTS IF ISSUES ARE NOT ADDRESSED BY THE CORPORATION. THIS OCCUR ON INTERSTATE 66 IN WASHINGTON, DC. IMMEDIATE RECALL OF ALL VEHICLES FROM GMC NEEEDS TO BE INITIATED.

GRADUAL COOLANT LOSS OVER TIME AND NO EVIDENCE OF LEAK. THIS WAS DUE TO A CRACK IN THE CYLINDER HEAD THAT GM ADMITTED TO KNOWING ABOUT IN TSB 06-06-01-019B ON JUNE 12, 2007). COOLANT WAS SLOWLY LEAKING INTO THE OIL, BUT WAS UNNOTICEABLE UNTIL IT STARTED TO AFFECT OIL PRESSURE FROM THE OIL BECOMING SLUSHY AND RUINING THE ENGINE. THIS ENDED UP RESULTING IN RESULTED IN THE LOW ENGINE OIL LIGHT SUDDENLY COMING ON AND THE CAR TO STOP RUNNING ON A HIGHWAY. THE ENGINE STARTED STEAMING AND THE CAR WAS OVERHEATING. MECHANIC IS NOW SAYING THE ENGINE IS IN AN UNOPERABLE SHAPE DUE TO DRIVING WITH CONTINUED LOW OIL PRESSURE (NO LIGHT HAD APPEARED UNTIL DAY OF INCIDENT). GM HAD SENT OUT A BULLETIN ADMITTING TO THE ISSUE BUT DID NOTHING TO NOTIFY THEIR CUSTOMERS. THEY SHOULD IMMEDIATELY RECALL THE AFFECTED VEHICLES AND/OR PAY FOR A REPLACEMENT. I HAD JUST PUT IN A NEW TRANSMISSION TO MY GMC ENVOY, EXPECTING IT TO LAST FOR YEARS.

TL* THE CONTACT OWNS A 2003 GMC ENVOY XL. WHILE THE VEHICLE WAS STATIONARY, THE ENGINE WARNING INDICATOR REMAINED ILLUMINATED. IT WAS DIAGNOSED THAT THE FUEL TANK FRACTURED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 155,000.

WHILE FILLING UP MY VEHICLE WITH GAS AT SAMSCLUB, IT BEGAN LEAKING CONTINUOUSLY FROM THE TANK. WE REPLACED THE FILLER NECK HOSE, BUT IT TURNS OUT THE GAS TANK HAS A CRACK AT THE TOP. WHEN YOU WALK BY, YOU COULD SMELL THE FUMES.

MY CAR WILL SHUT OFF WHEN I AM EITHER TURNING OR SLOWING DOWN WITHOUT ANY WARNING, I PUT THE CAR IN NEUTRAL, TURN THE KEY OFF THEN ON AGAIN AND IT STARTS LIKE NOTHING HAPPENED. THE ENGINE DOESN'T SHOW ANY WARNING LIGHTS IT JUST SHUTS OFF. THIS HAS HAPPENED NOW ABOUT 6 TIMES. I DON'T HAVE THE MONEY TO TAKE IT TO THE DEALER, BUT IF I AM GIVEN AN IDEA OF WHAT TO LOOK FOR I CAN TAKE IT TO MY MECHANIC WHO IS VERY QUALIFIED AND DID REPLACE A SENSOR THAT WENT BAD. PLEASE HELP

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, THE CHECK ENGINE WARNING LIGHT ILLUMINATED AND THERE WAS LOSS OF ENGINE POWER. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS DIAGNOSED THAT THE SENSOR PEDAL, THE CLUTCH FAN, WIRING TERMINALS, AND ACCELERATOR PEDAL NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE APPROXIMATE FAILURE MILEAGE WAS 170,000 AND THE CURRENT MILEAGE WAS 175,00. *TR

TL* THE CONTACT OWNED A 2003 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, THE ENGINE COMPARTMENT ENGULFED INTO FLAMES WITHOUT WARNING. THE FIRE DEPARTMENT WAS NOTIFIED AND NO INJURIES WERE REPORTED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT OFFER ANY ASSISTANCE. THE VIN WAS NOT AVAILABLE. THE VEHICLE WAS DECLARED DESTROYED. THE FAILURE AND CURRENT MILEAGES WERE 79,000.

ONE OF THE OIL COOLER LINE ON MY 2003 GMC ENVOY IS CRACKED AND LEAKING TRANSMISSION FLUID ON THE CATAYLIC CONVERTER. THIS IS A SERIOUS FIRE HAZARD DUE TO THE EXTREMELY HIGH TEMPERATURE OF THE CONVERTER DURING NORMAL OPERATIONS. *KB

THE CATAYTIC CONVERTER BROKE INTO PIECES AND THE CAR WOULD NOT GO ABOVE 25 MPH. *JS

CHECK ENGINE LIGHT ILLUMINATED ON INSTRUMENT CLUSTER. DIAGNOSTICS INDICATED A CODE PO 442. THIS CODE IS INDICATIVE OF A FUEL SYSTEM LEAK IN THE EVAPORATIVE EMISSION SYSTEM. REPLACED GAS CAP. PROBLEM NOT RESOLVED. FILLED VEHICLE WITH GASOLINE IN OCTOBER 2010 AND SEVERAL TIMES SINCE. STRONG ODOR OF GASOLINE IS PRESENT. EACH TIME FUEL NOZZLE FAILS TO SHUT OFF FUEL FROM GASOLINE PUMP AND GASOLINE IS SPILLED ON THE GROUND NEAR DRIVER SIDE REAR DOOR CREATING AN ENVIRONMENTAL AND MAJOR SAFETY HAZARD. VEHICLE NEVER IN ACCIDENT OR MODIFIED IN ANY WAY. VEHICLE HAS 62,000 MILES. A COURTESY GENERAL MOTORS REPAIR PROGRAM IS IN PLACE FOR THESE VEHICLES IF THE LONG WHEELBASE MODELS. NUMEROUS OCCURRENCES IN THE SHORT WHEELBASE MODELS ALSO. THIS IS A KNOWN DEFECT ACCORDING TO THE GM DEALER THAT SERVICES THE VEHICLE, BUT THEY WANT OVER $1500 TO REPLACE THE FUEL TANK AND THE TANK UNIT WHICH INCLUDES THE FUEL PUMP, GAUGE, AND HOSE CONNECTIONS. THERE IS NO GUARANTEE THIS WILL FIX THE DIAGNOSTIC CODE THAT SETS THE CHECK ENGINE LAMP, OR THE PROBLEM OF GASOLINE LEAKAGE/SPILLAGE. THE VEHICLE WILL NOT PASS A STATE SAFETY INSPECTION AND THEREFORE IS NOT ALLOWED ON THE ROAD. A FORCED RECALL SHOULD ABSOLUTELY BE MADE FOR THESE VEHICLES. AT A COST OF OVER $35,000 FOR THIS VEHICLE, AND THE HAZARDS IT REPRESENTS, IT IS A TOTAL TRAVESTY THAT GM REFUSES TO STAND BEHIND THEIR PRODUCT. *TR

THROAT OF GAS TANK LEAKING ON A 2003 ENVOY. REVIEWING INTERNET, FOUND MANY SIMILAR PROBLEMS ON THE ENVOY'S AND STATED IN 2007 THAT NHTSA WAS INVESTIGATING. MECHANIC STATED VERY UNUSUAL TO LEAK IN THAT SPOT. ALSO, HAVE REPLACED BOTH HEAD LIGHT SOCKETS DUE TO BURNING UP. HAVE TALKED TO MANY ENVOY OWNERS WITH THE SAME PROBLEM. WHEN BULB BURNS OUT AND THE RECOMMENDED BULB IS PUT IN PLACE THE SOCKET AND WIRING GETS SO HOT THAT THE SOCKET IS CHARRED AND IS NO LONGER FUNCTIONAL. WIRES HAVE TO BE CUT AND A NEW SOCKET WIRED IN. *TR

2003 GMC ENVOY SLE WITH 42,000 MILES. CHECK 4 WDRIVE LIGHT CAME ON THEN WENT BACK OFF. DEALER STATED THAT THE TCCM HAD TO BE REPROGRAMMED DUE TO A BULLETIN. IT COST ME OUT OF POCKET NO WARRANTIES COVER THIS. ALSO THE FAN CLUTCHES WENT OUT BUT WAS REPLACED BY EXTENDED WARRANTIES. I'M ALSO TOLD BY DEALER THAT THE STEERING LINKS ARE WORN & SHOULD BE REPLACED. THIS TOO IS AT MY COST. I HAVE ONLY HAD THIS CAR 1 YEAR. THESE HAPPENED WITH JUST A FEW WEEKS OF EACH OTHER. *TR

THE VEHICLE WAS STEERED TO THE SIDE OF THE ROAD AND TOWED. THE DEALER STATED THAT THE ENGINE LOCKED AND NEEDED TO BE REPLACED DUE TO AN OIL DRAIN PLUG THAT LOOSENED.

WE BOUGHT THIS CAR USED. WELL BEFORE WE BOUGHT IT, THEY HAD THE A/C FIXED, DUE TO IT NOT WORKING PROPERLY. WELL THE REAR A/C AND HEAT STILL DO NOT WORK. SOMETIMES IT COMES ON, AND OTHER TIMES IT DOES NOT. IT DOES NOT GIVE OUT HEAT AT ALL IN THE REAR. THIS IS A REAL ISSUE FOR US AND MANY OTHERS WITH CHILDREN. I HAVE READ PLENTY OF OTHER REPORTS STATING THE SAME OR VERY CLOSE. IN ALL IN ALL, THIS SHOULD BE RECALLED AND FIXED. THESE CARS ARE WAY TO EXPENSIVE TO HAVE THIS ISSUE AND NOT HAVE GMC STEP UP TO THE PLATE AND FIX THEIR ISSUE. *TR

VEHICLE COOLING FAN CLUTCH MAKING TICKING SOUNDS DUE TO THE "PULSING OF THE SOLENOID AS DESCRIBED IN THE TECHNICAL SERVICE BULLETIN RELEASED BY GENERAL MOTORS (#05-06-06-004), WHICH SPECIFIES NOT TO REPLACE FAN CLUTCH, BUT REPROGRAM THE PCM. THIS SHOULD BE A RECALL COVERED BY GM, SINCE NO PARTS ARE BROKEN AND THE ONLY PROBLEM IS WITH THE MANUFACTURER'S SOFTWARE. CONSUMER CAN ONLY GET THIS FIXED BY GM DEALER. THIS EXPENSE SHOULD BE COVERED UNDER A RECALL BY GM SINCE IT INVOLVES ONLY THE DEFECTIVE COMPUTER PROGRAM. THE ARE NOT PARTS TO REPLACE, JUST A REPROGRAMMING OF THE COMPUTER. *TR

THE REAR DRIVER DOOR POPPED OPEN AND WON'T CLOSE. THE FAN CLUTCH FAILED 2 WEEKS AFTER I PURCHASED THE VEHICLE. I THOUGHT THE TRANSMISSION WENT OUT BECAUSE IT WAS WINDING REALLY HIGH AND NOT DRIVING NORMALLY. ALSO THE REAR PASSENGER DOORS ON BOTH SIDES HAVE MALFUNCTIONED. THE WINDOW ON THE PASSENGER REAR WENT OUT. I HAVE NOT CORRECTED THE FAILURES AS OF NOW. *TR
