NHTSA Complaint #10494824 — 2002 BUICK RENDEZVOUS

MY VEHICLE WARMS UP FINE AND AS I START TO DRIVE THE ENGINE TEMP RISES TO A HOT CONDITION AND THE HEATER STARTS TO BLOW COLD AIR. THE SYSTEM HAS BEEN FLUSHED, THE HEATER CORE HAS BEEN FLUSHED, THERMOSTAT HAS BEEN CHANGED. I'VE BEEN DOING ALOT OF RESEARCH ON THESE PROBLEMS AND THERE ARE THOUSANDS OF OVERHEATING PROBLEMS THAT NEVER GO AWAY. IT DOESN'T MATTER WHAT YOU FIX THE PROBLEM REOCCURS. I FLUSHED THE SYSTEM AND COULDNT GET IT TO REPEAT UNTIL A COUPLE DAYS LATER, THEN I CHANGED THE THERMOSTAT WITH THE SAME RESULT. I NEVER GET A WARNING LIGHT FOR COOLANT TEMP BUT ENGINE TEMP INCREASES AND CAR WILL STALL AND WONT RESTART UNTIL IT COOLS DOWN. AFTER 2 WEEKS OF WORKING WITH THIS I HAVE THE VEHICLE PARKED AND TRYING TO FIGURE OUT WHY GM DOES NOT RECALL THESE CARS AND FIX THEM. I WAS TOLD THE ONLY WAY TO COMPLETELY FIX THIS PROBLEM IS A NEW 3.4L ENGINE FROM GM. WHO CAN AFFORD THAT, NOT ME. I HAVE CONTACTED BUICK BUT NOTHING BUT A REPORT WAS FILED AND ADDED TO THE PILE OF OTHER COMPLAINTS. IF THIS HAPPENED AT 70 MPH ON A HIGHWAY IT COULD BE VERY DANGEROUS. *TR
