WHILE DRIVING THE ENVOY AT ABOUT 45 MPH, A WARNING LIGHT SAYING "REDUCED ENGINE POWER" CAME ON SUDDENLY, THE CAR DROPPED DOWN TO ABOUT 20 MPH, AND THAT CONTINUES TO OCCUR. I CAN TURN OFF AND RESTART THE CAR, BUT THE PROBLEM RETURNS WITHIN A MINUTE AFTER DRIVING IT AGAIN. I STARTED INVESTIGATING WHAT THAT MEANS ONLINE, AND, AS WITH ANYTHING ELSE ON THE INTERNET, I SEE MANY OPINIONS, GUESSES, AND POSSIBILITIES. COULD BE A BAD SENSOR, BAD THROTTLE CONTROL, BAD WIRE CONNECTIONS, ETC. BUT THIS MUCH APPEARS CLEAR: (1) IT IS A GM PROBLEM, AND A VERY, VERY COMMON ONE. (2) IT IS A DANGEROUS PROBLEM. THIS SEEMS PRETTY OBVIOUS - THE CAR SUDDENLY LOSES SPEED AND EVIDENTLY SOMETIMES STALLS OUT ALTOGETHER. BUT HEARING ABOUT SO MANY OTHER PEOPLE'S SCARY EXPERIENCES JUST CONFIRMS THIS. (3) IT CAN BE DIFFICULT AND EXPENSIVE TO DIAGNOSE AND FIX. WHEN I THINK OF THESE FACTS, COUPLED WITH GM'S RECENT HISTORY, I IMMEDIATELY THINK "RECALL." THIS CERTAINLY APPEARS TO BE AN APPROPRIATE SITUATION FOR A MANUFACTURER TO STEP IN AND FIX THE ISSUE BEFORE MORE PEOPLE GET ANGRY WITH GM, GET HURT, OR GET KILLED. I CALLED THE DEALER WHO SOLD THE CAR (I AM THE SECOND OWNER), IN COLUMBUS, OHIO. I WAS TOLD THAT I CAN BRING IT IN FOR A DIAGNOSIS FOR $110. (GEE, THANKS - WOULDN'T HAVE THOUGHT OF THAT.) THE CUSTOMER REP LOOKED UP THE VIN AND SAID THAT THE VEHICLE WAS NOT ELIGIBLE FOR RECALL OR ANY SPECIAL POLICY. THEREFORE, I AM CONTACTING YOU IN HOPE THAT SOMETHING ELSE CAN BE DONE.

ROUGH IDLE WHILE IN PARK AND WHILE SHIFTING TO SECOND GEAR. ENGINE LIGHT FLASHING, OIL IN SPARK PLUG WELLS, CYLINDER MISFIRE ON CYLINDER #4. CHANGED SPARK PLUGS & WIRES, THIS DID NOT REMEDY THE SITUATION. I HAD THE SUV FOR 1 MONTH AND THE DRIVE TRAIN WENT BAD. TWO MONTHS LATER, I GOT MY TRUCK BACK FROM THE MECHANIC BECAUSE PARTS NEEDED TO BE CERTIFIED BY A GM ENGINEER. I HAVE HAD NOTHING BUT MECHANICAL FAILURES SINCE 2010 WHEN I BOUGHT THE VEHICLE. NOW I HAVE AT LEAST FIVE TROUBLESHOOTING CODES AND NOW I'M BEING TOLD THAT THE CYLINDER HEAD NEEDS REPLACED. THIS SHOULDN'T BE HAPPENING AND I KNOW NOW THAT I WILL NEVER BUY ANOTHER GMC PRODUCT EVER AGAIN. *TR

WE WERE AGAIN DRIVING ON INTERSTATE 5 AT 60 MPH WHEN THE ENGINE JUST STOPPED. WE WERE ONCE AGAIN ABLE TO COAST TO THE SIDE OF THE ROAD. THIS IS THE 2ND TIME OUR ENVOY JUST STOPPED RUNNING AT 60 MPH. AGAIN, THE MECHANICS COULD NOT FIGURE OUT WHY THIS HAPPENED. I HAPPENED ONE MORE TIME, BUT I DO NOT HAVE THE DATE. SO THAT MAKES THREE TIMES OUR 2002 GMC ENVOY SUDDENLY QUIT RUNNING WHILE AT A HIGH SPEED ON THE FREEWAY. WE ARE CONCERNED THIS IS AN IGNITION PROBLEM LIKE WITH THE OTHER GM VEHICLES THIS HAS HAPPENED TO. *TR

OVER THE YEARS I OWNED THIS VEHICLE, I HAD IT SERVICED NUMEROUS TIMES FOR ENGINE FAILURE. THE LAST AND FINAL TIME, THE DEALERSHIP (EWING AUTOMOTIVE) COULD NOT FIND ANYTHING WRONG. HOWEVER, WHILE TRAVELING ON THE HIGHWAY AT 60 MILES AN HOUR WITH A FULL TANK OF GAS, I LOST ALL POWER STEERING CONTROL AND THE CAR STOPPED DEAD. THIS WAS EXTREMELY DANGEROUS AND LED ME TO TAKE A MINIMAL AMOUNT IN A SALE, JUST TO GET RID OF THIS DANGEROUS CAR. IT IS VERY DISAPPOINTING TO LEARN THAT GM WAS FULLY AWARE OF THIS DEADLY ISSUE. *TR

EVERYTHING STARTED APRIL LAST YEAR AND ITS ONE THING AFTER ANOTHER SINCE. FIRST MY ENGINE STARTED STALLING, WHILE DRIVING. ONE INCIDENT, I LOST HALF A TANK OF GAS WITHIN A 15 MINUTE RIDE, WHICH I HAVE A 17 GALLON TANK. THEN WHILE DRIVING ON AN EXPRESSWAY, IT SUDDENLY DROPPED FROM 70 TO 20 BEFORE I COULD GET OVER TWO LANES TO GET OUT OF THE WAY OF TRAFFIC. IVE CLEANED THE THROTTLE BODY, IVE CLEANED THE CAMSHAFT ACTUATOR, IVE REPLACED THE AIR FILTER, FUEL FILTER, AND THE OIL TWICE WITHIN A 8 MONTH PERIOD, AND YET IT STILL CONTINUES TO STALL. NOW I RECENTLY CHANGE THE WATER PUMP TO SEE IF THAT WOULD HELP, EVEN THOUGH MY CAR WAS NOT OVER HEATING, NOW ITS STALLING EVEN WORSE; I CANT EVEN MAKE IT THROUGH A DRIVE THROUGH WITHOUT HAVING TO START IT TWICE. SECOND AND EVEN SCARRIER ISSUE, I HIT POT HOLE ONE DAY AND BEFORE I COULD MAKE 15 MILES, I HEARD GRINDING. A CV JOINT HAD TO BE REPLACED, THEN TWO DAYS AFTER THAT THE OTHER CV JOINT BROKE OFF AND BROKE MY FRONT AXLE DISCONNECT ASSEMBLY. DID I HIT ANYBODY? NO THANK GOD I WAS IN THE RIGHT HAND LANE AND COULD GET OVER WITHOUT HITTING ANYONE OR CAUSING INJURY TO MYSELF. IVE REPLACED BOTH CV JOINTS AND THE ASSEMBLY NOW AND EVEN DID THE STRUTS WHILE I WAS AT IT, BUT HAVE ALSO BEEN TOLD I NEED CONTROL ARMS NOW. AND STILL MY CAR IS STALLING, GRINDING WHEN I TURN AND I CANT GET THE CHECK ENGINE LIGHT TO CLEAR LONG ENOUGH TO GET IT INSPECTED. MY DRIVERS SIDE WINDSHIELD WORKS WHEN IT WANTS TO AND NOW THE CAR IS STARTING TO VIBRATE UNBELIEVABLY. IVE KEPT MY OIL CHANGED, IVE KEPT MY FILTERS CHANGED, IVE NEVER TAKEN THIS THING OFF ROAD AND HAVE HAD IT OVER 7 YEARS AND JUST IN THE LAST YEAR I HAVE DUMPED MORE MONEY IN THIS CAR THAN I HAVE SINCE IVE OWNED IT. *TR

WHEN I START THE TRUCK IN THE MORNING IT SOUNDS LIKE THE ENGINE IS REVVED UP WITH THE LOUD FAN NOISE. I HAD THE FAN CLUTCH REPLACED INDEPENDENTLY AND THE LOUD NOISE CONTINUES AND A SLIGHT LOSS OF POWER AT TIMES WHILE DRIVING AND IT FEELS LIKE IT'S TAKING TOO LONG SHIFT INTO THE NEXT GEAR. THE NOISE IS REALLY HEARD WHEN YOU ACCELERATE ON THE GAS PEDAL. *TR
