2005 GMC Envoy engine and engine cooling problems

“WHEN BACKING THE VEHICLE TO LEAVE A LOCAL RESTAURANT, DRIVER STRUCK VEHICLE BEHIND HER. THIS HAPPENED SO QUICKLY THAT IT WAS UNKNOWN TO THE DRIVER HOW THE VEHICLE TRAVELED SO QUICKLY THAT DRIVER HAD NOT EVEN HAD A CHANCE TO TURN THE STEERING WHEEL TO AVOID STRIKING THE OTHER VEHICLE. DRIVER PLACED VEHICLE IN DRIVE TO PULL OVER TO ASSESS THE DAMAGE. WHEN PLACED INTO DRIVE, THE VEHICLE LURCHED FORWARD AND CONTINUED TO ACCELERATE DESPITE THE BRAKES BEING APPLIED. THE VEHICLE STRUCK A BRICK RESTAURANT. DAMAGE WAS ALSO DONE TO THE INTERIOR BATHROOM OF THE FACILITY AND THE BUSINESS HAD TO CLOSE TO ASSURE SAFETY OF IT'S STAFF/CUSTOMERS. WITNESS STATES THE VEHICLE WAS OBVIOUSLY LURCHING AND APPEARED TO HAVE A MECHANICAL PROBLEM. THE DRIVER'S FOOT BOUNCED OFF OF THE BRAKE PEDAL ON IMPACT LODGING IT UNDERNEATH THE BRAKE PEDAL. IT WAS ALSO NOTED THAT NEITHER FRONT AIRBAGS DID DEPLOY. DRIVER DID NOT SEEK MEDICAL ATTENTION HOWEVER DRIVER'S FOOT WAS BADLY BRUISED.”

“ON JULY 28, 2014 I WAS GOING DOWN A HILL AND THE ENGINE SHUT OFF COMPLETELY. FORTUNATELY I WAS ONLY GOING APPROXIMATELY 5 MPH AND WAS ABLE TO COAST ACROSS THE MAIN STREET AND WAS ABLE TO COAST INTO A PARKING SPOT. I TRIED RESTARTING MY ENVOY WITH NO LUCK SO I HAD THE TRUCK TOWED TO THE LOCAL GMC DEALERSHIP AND WAS TOLD THAT THE IGNITION SWITCH HAD GONE BAD. I HATE TO THINK WHAT WOULD HAVE HAPPENED IF I WAS GOING FASTER OR GOING DOWN A STEEP MOUNTAIN BECAUSE WHERE I LIVE I AM SURROUNDED BY MOUNTAINS. I AM NOT SURE IF ANYONE ELSE EXPERIENCED THIS PROBLEM WITH A SIMILAR VEHICLE. I DO KNOW THAT OTHER GM CARS AND VEHICLES ARE BEING RECALLED FOR THIS SAME SITUATION BUT WAS TOLD THAT MINE IS NOT UNDER A RECALL AT THIS TIME. *TR”

“MY 2005 GMC ENVOY HAS STARTED EXPERIENCING A KNOCKING SOUND IN THE RIGHT REAR PASSENGER SIDE. IT STARTS APPROXIMATELY A MINUTE AFTER THE VEHICLE STARTS AND STOPS WITHIN A MINUTE OR SO. IT HAPPENS WHEN THE CAR IS MOVING OR IDLE. THIS STARTED YESTERDAY EVENING. NOT SURE WHAT IS CAUSING IT. EVERYTHING IS RUNNING FINE IN THE VEHICLE. THERE MUST BE OTHER SIMILAR COMPLAINTS AND RESOLUTIONS. *TR”

“I HAVE HAD A PROBLEM IN THE PAST WITH THE FUEL GAUGE READING EMPTY CONTINUOUSLY AS I HAVE READ FROM MANY OTHER COMPLAINTS. RECENTLY I EXPERIENCED A PROBLEM WITH THE OIL PRESSURE GAUGE. AT FIRST THE CHECK ENGINE LIGHT APPEARED INTERMITTENTLY AND THEN THE OIL PRESSURE GAUGE DROPPED TO ZERO, AT WHICH TIME THE MESSAGE IN ON THE LCD READING SAID "STOP ENGINE" AND "OIL PRESSURE LOW". I IMMEDIATELY WENT TO MY GAS STATION AND CHECKED THE OIL, WHICH WAS ONLY DOWN A 1/4 TANK. MY MECHANIC STOPPED THE CAR AND STARTED IT AGAIN AND THE OIL PRESSURE GAUGE RESET ITSELF BUT ONCE I STARTED TO DRIVE THE CAR AGAIN, THE OIL PRESSURE DROPPED. MY MECHANIC BELIEVES IT IS ANOTHER SENSOR PROBLEM LIKE THE FUEL SENSOR BUT IS NOT COMPLETELY SURE. I ONLY STARTED WITH THIS ISSUE TODAY BUT IT IS MORE WORRISOME TO ME THAN KEEPING TRACK OF HOW MUCH GAS SHOULD BE IN MY TANK. I AM CURIOUS TO KNOW IF OTHERS HAVE STARTED TO EXPERIENCE THIS PROBLEM. I HAVE HAD THE CAR SINCE IT WAS BRAND NEW AND HAVE DRIVE 79000 MILES. I ALSO HAD A MAJOR ISSUE WITH THE SUSPENSION SYSTEM WITH I BELIEVE IS COMMON IN THIS VEHICLE. *TR”

“EXHAUST MANIFOLD IS CRACKED. HAD EXHAUST MANIFOLD AND GASKETS REPLACED. TOOK 5 WORKING DAYS TO FIX. CHECKED ON LINE AND FOUND MANY COMPLAINTS ON THE ENVOY AND TRAILER BLAZER 'S MANIFOLD. *TR”

“2005 GMC ENVOY XL HAS SEVERAL ISSUES WITH THE INSTRUMENT CLUSTER. THE BATTERY AND TEMPERATURE GAUGES ARE READING OFF THE SCALE PAST THEIR MAXIMUM READINGS. IT SHOULD ALSO BE NOTED THAT THIS VEHICLE ALSO HAD ISSUES WITH THE FUEL GAUGE SENDING UNIT AND THE ENGINE THERMOSTAT. *TR”
