TL* THE CONTACT OWNS A 2002 GMC ENVOY. WHILE DRIVING AT ANY SPEED, THE ENGINE SHUT OFF WITHOUT WARNING. THE VEHICLE RESTARTED INTERMITTENTLY. THE FAILURE RECURRED MULTIPLE TIMES. THE DEALER STATED THAT THE VIN WAS EXCLUDED FROM NHTSA CAMPAIGN NUMBER: 04V289000 (ENGINE AND ENGINE COOLING). THE MANUFACTURER WAS NOTIFIED. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 82,000.

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...

VEHICLE LOSES POWER DRASTICALLY WHEN GOING UP ANY INCLINE. WAS GOING 65 AND SPEED DROPPED TO 35 GOING UP SLIGHT GRADE HILL.

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

TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT STATED THAT AFTER MULTIPLE ATTEMPTS, THE VEHICLE FAILED TO START. THE VEHICLE WAS TOWED TO A DEALER. THE TECHNICIAN MADE THE CONTACT AWARE OF RECALL NHTSA CAMPAIGN ID NUMBER: 04V289000 (ENGINE AND ENGINE COOLING). HOWEVER, THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 1,001.

WE WERE DRIVING ON INTERSTATE 5 AT 60 MPH WHEN THE ENGINE JUST QUIT. WE WERE ABLE TO COAST TO THE SIDE OF THE FREEWAY. HAD TO HAVE THE ENVOY TOWED TO OUR MECHANIC. THEY COULD NOT FIND ANYTHING WRONG WITH IT. WE NOW BELIEVE IT WAS AN IGNITION PROBLEM LIKE WITH THE OTHER GMC VEHICLES. *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
