NHTSA Complaint #10166056 — 2004 GMC ENVOY

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. *JB
