TL* THE CONTACT OWNS A 2002 CHEVROLET BLAZER. THE CONTACT STATED THAT WHILE HIS SISTER WAS DRIVING AT 20 MPH, THE ENGINE COOLING FAN EXPLODED AND THERE WAS SMOKE. THE FAILURE OCCURRED WITHOUT WARNING. THE VEHICLE WAS DRIVEN TO THE CONTACT'S SISTER'S RESIDENCE. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE CONTACT'S BROTHER INSPECTED THE VEHICLE AND DETERMINED THAT THE RADIATOR AND THE FAN NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BY HER BROTHER. THE MANUFACTURER WAS NOT CONTACTED AND WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 145,000.
THE INTAKE MANIFOLD GASKET IS LEAKING THE INTAKE MANIFOLD GASKET WAS LEAKING ON MY CHEVROLET SILVERADO LAST YEAR I HAVE BEEN TOLD BY 4 ASE CERTIFIED MECHANICS THAT CHEVROLETS HAVE EXTREMELY TOO MANY INTAKE MANIFOLD GASKET LEAKING PROBLEMS BECAUSE OF THE DEXRON ANTIFREEZE AND THE GASKETS THEY USED. *TR
WHILE DRIVING, THE TEMPERATURE GAUGE SPIKED AND THE CHECK GAUGES LIGHT CAME ON. ONE OF THE BOLTS THAT HOLDS THE THERMOSTAT HOUSING TO THE MANIFOLD HAD SHEARED OFF DUE TO BOLT BRITTLENESS. THIS CAUSED A SERVE LOSS OF COOLANT AND THE REMAINDER OF THE THERMOSTAT HOUSING BOLTS TO BECOME BROKEN OFF IN THE INTAKE MANIFOLD. RESULTING IN A REPAIR OF AT LEAST $1,000 DUE TO HAVING TO REPLACE THE MANIFOLD. THE SHOP WAS ONLY ABLE TO EXTRACT ONE BROKEN BOLT FROM THE MANIFOLD. THIS VEHICLE IS A LEMON. WE HAVE REPLACED EVERYTHING ON IT, SOME THINGS MORE THAN ONCE INCLUDING THE ENGINE, TRANSMISSION, AND MULTIPLE RADIATORS ALL UNDER 75,000 MILES. WE HAVE REPLACED THE GAS CAP TO THE RADIATOR CAP AND EVEN THE WINDSHIELD TOO. THIS WILL BE THE SECOND INTAKE MANIFOLD AS THE ENGINE HAD TO BE REPLACED 5 YEARS AGO DUE TO FAILURE OF THE HEAD GASKET DUE TO A FAULTY GM DESIGN ON ENGINES MADE BETWEEN 2000 AND 2004 AND DEXICOOL COOLANT ISSUES. *TR
DT*: THE CONTACT STATED AFTER PARKING THE VEHICLE FOR A FEW MINUTES, THE VEHICLE WOULD NOT RESTART. WHEN THE KEY WAS TURNED IN THE IGNITION THE ENGINE WOULD NOT TURN OVER BUT ONLY MADE A WHINING NOISE. THE VEHICLE WAS TOWED TO AN INDEPENDENT REPAIR SHOP, UPON INSPECTION THE ENGINE HAD SEIZED. THE TIMING CHAIN HAD FRACTURED, THE SPARKS PLUGS HAD MELTED AND THE PISTONS HAD FAILED. THE DEALER AND MANUFACTURER WERE ALERTED.
THE HEATER AND DEFROSTER FAILED TO GENERATE HEAT. NO EVENTS LEADING UP TO FAILURE. THIS FALL WHEN WE NEEDED THE HEAT AND WINDOW DEFROSTER JUST LUKE WARM AIR WAS COMING OUT. THE INTAKE HOSE TO THE HEATER WAS HOT THE OUT TAKE HOSE WAS COLD. THIS FAILURE CAUSES A MAJOR SAFETY ISSUE BECAUSE THE FRONT WINDOW WILL NOT UN-FOG AND THE ICE AND SNOW WILL NOT MELT OFF THE FRONT WINDOW. THE DRIVER CAN NOT SEE OUT OF THE FRONT WINDOW. THERE IS NO WARNING TO THIS PROBLEM. RESEARCH THIS PROBLEM ON THE WEB AND THERE ARE NUMEROUS OTHER PEOPLE AND VEHICLES WITH THE SAME PROBLEM. IT APPEARS TO BE CAUSED DEX-COOL COOLANT. THIS WEB SITE HTTP://WWW.GEOCITIES.COM/B_GILLIE/DEXCOOL_PROBLEMS.HTML HAS MORE INFORMATION ON THIS PROBLEM. *JB
IMMEDIATELY FOLLOWING PURCHASE OF A 2002 CHEVROLET BLAZER IN AUGUST 2002, I NOTICED A LOUD ROARING NOISE COMING FROM UNDER THE HOOD WHICH OCCURED MOSTLY UPON STARTUP WHEN ENGINE WAS COLD AND PUT INTO DRIVE GEAR. THIS NOISE WAS ALSO INTERMITTENTLY NOTICED AFTER COMING TO A STOP AND THEN ACCELERATING. BY THE TIME I DROVE IT BACK TO THE DEALERSHIP, IT WAS NOT DOING IT. SINCE PURCHASE, 2 REPLACEMENT BATTERIES HAVE BEEN INSTALLED. SERVICE DEPT AT DEALERSHIP SAID ALTERNATOR WAS DRAINING THE BATTERY AND REPLACED THE ALTERNATOR. CAR IS STILL DOING THIS BUT DEALER IS UNABLE TO DUPLICATE AND SAYING LOUD ROAR IS MOST LIKELY NORMAL. NOW SEVERAL ACQUAINTANCES HAVE SAID THEY HAD THE EXACT SAME PROBLEM WITH THEIR BLAZERS EVEN THOUGH THEY WERE A DIFFERENT YEAR MODEL. ONCE THE WARRANTY RUNS OUT, THIS PROBLEM COULD ADD UP TO QUITE AN EXPENSE.*AK
WHILE DRIVING 55 MPH VEHICLE STALLED. *AK
I HAVE HAD TO REPLACE THE INTAKE MANIFOLD GASKET ON 3 CHEVROLETS IN THE PAST 3 THREE YEARS TODAY BEING THE THE THIRD. IF THERE IS A PROBLEM WITH THE GASKETS OR COOLANT <DEXCOOL> THE REPAIR SHOULD BE DONE AT NO COST TO THE CONSUMER
WHILE DRIVING, DIRT AND DUST PARTICLES COME THROUGH THE VENTILATION SYSTEM. *AK THE EXHAUST SYSTEM AND CATALYTIC CONVERTERS IS BACKING UP THROUGH THE AIR AND HEAT VENTILATION SYSTEM. THIS PROBLEM WAS DUE TO THE VEHICLE BEING REAR ENDED *CB *JB
CONSUMER STATED WHILE DRIVING AT ANY SPEED AND WITH NO WARNING VEHICLE SHUT OFF, CAUSING CONSUMER TO PULL OFF THE ROAD. DEALER HAS INSPECTED THE VEHICLE SEVERAL TIMES, AND COULD NOT DUPLICATE OR CORRECT THE PROBLEMS. *AK
I M BUYING A 2002 CHEVROLET BLAZER NOW THE EMISSION EXHAUST SYSTEM HAS BEGUN TO LET OUT DUST HEAT OUT OF THE AIR VENT. AND MAKING MY HEAD HURT AND BODY HURT. THE WARRANTY SAID THAT IT IS THE EMISSIONS CONTROL SYSTEM WARRANTY. *CB
THE ENGINE STALLED WITHOUT WARNING, WHICH CAUSED THE CONSUMER TO PULL OVER ABRUPTLY. *JB. THE DEALER WAS UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. THE CONSUMER STATED AT ONE POINT TRANSMISSION FLUID LEAKED ONTO THE GROUND. *JB
THE CHECK ENGINE LIGHT ILLUMINATED, AND THEN THE VEHICLE LOST ALL POWER. *JB
AFTER ENGINE HAS WARMED UP, THERE IS A CONSTANT ENGING/TAPPING/RATTLE NOISE SIMILAR TO THE SOUND THAT BAD LIFTERS MAKE. THIS SOUND IS PREVALENT UNDER ALL CONDITIONS AND MORE PRONOUNCED ON ACCELERATION. I BROUGHT IT TO THE DEALERSHIP SEVERAL TIMES AND THEY INDICATED IT WAS A NORMAL SOUND PER DETROIT. DETROIT HAS A DOCUMENT ID#843248 THAT ADDRESSES THIS PROBLEM. I COMPLAINED TO GM AND THEY HAVE EXTENDED THE WARRANTY ON THE ENGINE TO 100,000 MILES OR 11/27/07 WHICHEVER COMES FIRST. I AM STILL NOT SATISFIED AS THE NOISE IS CONSISTENT AND AN IRRITANT. I HAVE LOOKED AT YOUR SITE FOR OTHER SIMILAR COMPLAINTS AND DO NOT SEE ANY. THERE MUST BE A MECHANICAL FIX TO THIS PROBLEM BUT IT IS BEING IGNORED. THE ENGINE SOUND HAS INCREASED SINCE IT WAS FIRST NOTICED INDECEMBER, 2002 AND REPORTED TO THE DEALERSHIP.*AK
