1999 CHEVROLET BLAZER Engine And Engine Coolingengine Problems

TL*THE CONTACT OWNS A 1999 CHEVROLET BLAZER. WHILE DEPRESSING THE BRAKE PEDAL AT 5 MPH, THE VEHICLE SURGED FORWARD WITHOUT WARNING. THE MECHANIC WAS UNABLE TO DIAGNOSE THE CAUSE OF FAILURE. THE CONTACT STATED THAT SHE EXPERIENCED THE SAME FAILURE IMMEDIATELY AFTER LEAVING THE MECHANIC. THE VEHICLE WAS TAKEN TO ANOTHER MECHANIC WHO STATED THAT THE MULTI-PORT FUEL INJECTION SYSTEM NEEDED TO BE REPLACED. HE REPLACED THE PART, BUT THE FAILURE CONTINUED. THE MECHANIC STATED THAT THE VEHICLE MAY NEED TO HAVE ITS SPARK PLUGS REPLACED OR CLEANED. THE SPARK PLUGS HAVE NOT BEEN REPLACED. APPROXIMATELY THREE DAYS LATER, THE VEHICLE FAILED TO START. THE MECHANIC STATED THAT THE MULTI-PORT FUEL INJECTION WAS DEFECTIVE AND REPLACED THE UNIT, BUT THE FAILURE CONTINUED. THE VEHICLE SURGED FORWARD AND BECAME INCREASINGLY WORSE. THE CURRENT MILEAGE IS 150,000 AND FAILURE MILEAGE WAS 130,000.

DURING MAINTENANCE, OWNER NOTICED COOLANT GETTING DIRTY. HAD IT FLUSHED FOUR TIMES. HEATER QUIT WORKING AFTER FIRST FLUSH. BROWNISH-GRAY SLUDGE WAS BLOCKING THE HEATER CORE. MECHANIC STATED IT WAS DUE TO A SMALL LEAK IN THE INTAKE MANIFOLD GASKET CAUSING SMALL AMOUNTS OF DIRTY AIR AND OIL TO MIX WITH COOLANT. SINCE HAVING GASKET REPLACED, COOLANT HAS NOT GOTTEN DIRTY AGAIN. VORTEC ENGINES 1999-2003 WERE PRONE TO THIS GASKET FAILURE. DEXCOOL DOESN'T MIX WELL WITH DIRT OR OIL. *NM

DT*: THE CONTACT STATED AN OIL LEAK WAS NOTICED AND THE VEHICLE WAS FIRST TAKEN TO A SERVICE DEALER, THEN TO AN INDEPENDENT MECHANIC. THE PROBLEM WAS IDENTIFIED AS A FAILED OIL COOLER LINE AND "O" RINGS. THE LINE AND RING WAS REPLACED. THE REPLACEMENT PARTS WERE NOT THE ISSUE AS MUCH AS THE ENGINEERING CAUSING EXPENSIVE LABOR COSTS FOR A SMALL PART TO BE REPLACED. THE MANUFACTURER WAS NOT CONTACTED.

I HAD VALVE NOISE AND TOOK TO LOCAL DEALER TO CHECK. DEALER CALLED AND TOLD ME IT NEEDED A VALVE JOB. AFTER THE VALVE JOB DEALER TOLD ME THERE WAS NOISE IN LOWER PART OF ENGINE AND THOUGHT THE MOTOR NEEDED TO BE REPLACED. THIS 1999 BLAZER HAS 68,000 MILES ON IT. I FEEL GM SHOULD COVER PART OF THIS EXPENSE. DEALER WOULD NOT HELP WITH THIS. *JB

WHILE DRIVING 45 MPH ENGINE FAILED AND SECURITY LIGHT STAYED ON. *AK

I DISCOVERED OIL LEAKING FROM MY 99 CHEVY BLAZER RECENTLY. I TOOK IT TO MY LOCAL INDEPENDENT MECHANIC AND THEY INFORMED ME THAT I HAVE TWO FAULTY OIL COOLING LINES THAT MUST BE REPLACED. UPON FURTHER INVESTIGATION, I HAVE DISCOVERED THOUGH SEVERAL LOCAL DEALERSHIPS AND SEVERAL INTERNET WEB SITES, THAT THIS IS A VERY VERY COMMON PROBLEM WITH 99 CHEVY BLAZERS. I CONTACTED GM CUSTOMER SERVICE BUT THEY TOLD ME THERE IS NO CURRENT RECALL FOR THIS DEFECT. SINCE THIS IS SUCH A COMMON PROBLEM AND COSTS SEVERAL HUNDRED DOLLARS IN REPAIR TO REMEDY, I WOULD LIKE TO PETITION THIS FOR A MANUFACTURERS RECALL.*AK

THE VEHICLE STALLED AND THEN CAUGHT FIRE. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. PLEASE PROVIDE FURTHER DETAILS. *JB

CONSUMER STATES THAT WHILE DRIVING ENGINE CHECK LIGHT WOULD COME ON. DEALER NOTIFIED.*AK

TRANSMISSION VALVE IS STICKING WHICH CAUSES THE CHECK ENGINE LIGHT TO COME ON. DEALER NOTIFIED. *AK

THE VEHICLE STALLED WITHOUT WARNING, WHICH CAUSED THE CONSUMER TO PULL OVER ABRUPTLY. *JB

WHILE DRIVING, THE VEHICLE STALLED AND CAUGHT ON FIRE. *JB

AFTER NOTICING THAT I WAS LOOSING ANIFREEZE IN MY VEHICLE, I RECENTLY HAD TO REPLACE THE INTAKE GASKETS IN MY 1999 CHEVY BLAZER. IT HAS JUST OVER 40,000 MILES. AFTER DOING RESEARCH, I'VE FOUND OUT THAT THIS IS A COMMOM PROBLEM W/ THE GM VEHICLES AND THAT THERE ARE THOUSANDS OF PEOPLE WHO HAVE HAD TO SPEND HUNDREDS OF DOLLARS IN REPAIRS TO HAVE THIS FIXED. IT CONVENIENTLY HAPPENS JUST AFTER THE WARRENTY PERIOD HAS EXPIRED. THIS IS CLEARLY UNFAIR TO THE CONSUMER AND I WOULD LIKE TO KNOW WHY GM HAS NOT BEEN FORCED TO CORRECT THIS PROBLEM.

THE VEHICLE EXPERIENCED AN OIL LEAK. *JB BOTH COOLER LINES WERE REPLACED. SCC

1999 CHEVY BLAZER SUDDENLY DIES WITHOUT WARNING - AT SLOW AND HIGH SPEED. MAY NOT RESTART IMMEDIATELY. CLOCK RESETS, AND ON ONE OCCASION THE REAR WINDOW UNLATCHED.*JB

RADIATOR HEATING AND COOLING DUE TO ENGINE COOLANT SLUDGES UP CREATING PROBLEMS WITH HEATER CORE AND OTHER PARTS. HAVE REPLACED PARTS AND EVEN ADDED A FILTER BUT STILL NOT GETTING THE PREFORMANCE FROM HEATER AS IT SHOULD. HAVE HEARD FROM TECHS AND COMPLAINTS.COM AND OTHERS ALOT OF COMPLAINTS PUT IN WHY NO RECALL.

CONSUMER NOTICED OIL LEAKING FROM UNDER VEHICLE. TECHNICIAN SERVICING VEHICLE INDICATED THAT OIL LINE NEEDED TO BE REPLACED. PLEASE PROVIDE FURTHER INFORMATION.*AK

CONSUMER STATED THAT VEHICLE SHUT OFF WITHOUT PRIOR WARNING AT STOP SIGN AND TRAFFIC LIGHT. DEALERSHIP IS AWARE OF PROBLEM.*AK

INTAKE LEAKING, RESEAL INTAKE, REMOVED TRANSMISSION FOUND REAR MAIN SEAL LEAKING AND OIL PAN GASKET REPLACED BOTH SEALS
