2002 CHEVROLET TRAILBLAZER Engine And Engine Cooling Problems

TL* THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT TRANSMISSION FLUID WAS LEAKING ONTO THE CATALYTIC CONVERTER FROM THE TRANSMISSION LINE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS. THE TECHNICIAN STATED THE TRANSMISSION COOLER LINES WOULD HAVE TO BE REPLACED DUE TO CORROSION ON THE INSULATED HEAT SHIELD. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 122,924. *TR

WHEN MY MECHANIC PUT MY TRUCK ON THE LIFT YESTERDAY TO CHANGE THE WATER PUMP, HE NOTICED THAT THE FRAME IS SO ROTTED THAT HE ADVISED ME NOT TO DRIVE IT.AND FOR WHO KNOWS HOW LONG, MY WIFE AND MYSELF, WHO ARE BOTH DISABLED, HAVE BEEN DRIVING THIS, PUTTING OURSELVES AND THE PUBLIC AT RISK. WHEN I BROUGHT IT TO A CHEVROLET DEALER, THEY JUST SAID, NO RECALLS ON IT, SORRY! SO NOW I HAVE TO FIGURE OUT A WAY TO GET MY WIFE AND MYSELF TO DOCTORS APPOINTMENTS, SHOPPING, AND ALL THE OTHER THINGS WE NEED A DEPENDABLE VEHICLE FOR. WE CAN'T DRIVE THIS, OR AFFORD TO FIX IT, AND WE HAVE NO MONEY TO BUY ANOTHER ONE. DID I MENTION THAT WE ARE FILING FOR BANKRUPTCY BECAUSE MY WIFE WAS MIS-DIAGNOSED BY A DOCTOR, LOST HER JOB, AND NOW IS IN A WHEELCHAIR? OR THAT OUR MORTGAGE IS...

WHEN I FIRST PURCHASED THE VEHICLE A COUPLE DAYS LATER I NOTICED THE STEERING COLUMNS ABILITY TO TURN WAS VERY HARD AND MAKING LOUD NOISES. I FOUGHT CONTINUOUSLY WITH THE DEALERSHIP TO FIX THE ISSUE AND FINALLY AFTER SEVERAL ATTEMPTS THEY AGREED TO FIX IT. THEN 2 MONTHS LATER WERE DRIVING MY SON TO THE AIRPORT AND THE CAR STOPPED AND BEGAN TO SMOKE, COME TO FIND OUT THE RADIATOR HAD A HOLE IN IT AND THERE WAS SOME TYPE OF TEMPORARY STOP LEAK STUFF PUT IN IT TO ALLOW A CONSUMER TO DRIVE FOR A SHORT AMOUNT OF TIME BEFORE THE PROBLEM WOULD ARISE AGAIN. SO NOW MY FAMILY AND I ARE OUT OF TRANSPORTATION AND IM STILL PAYING A CAR NOTE ON THIS VEHICLE, I FEEL TOTALLY TAKEN ADVANTAGE OF AND WONDER HOW ANY DEALER CAN GO TO SLEEP AT NIGHT KNOWING THEY'VE BEEN DECEPTIVE IN THE SELLING...

I WAS DRIVING HOME FROM WORK AND STARTED HEARING THE TRUCKS UNDERCARRIAGE START TO RATTLE AND GRIND ON THE BUMPS OF THE ROAD. I HAD A SUDDEN LOSS OF POWER ON ENGINE AND IT WOULDNT RESPOND TO MY PRESSING ON THE GAS. I BELIEVED THAT I HAD GAS IN THE TRUCK BECAUSE THE GAUGE READ HALF FULL AND APPARENTLY I WAS OUT OF GAS. SO I PROCEEDED TO PULL INTO A GAS STATION AND AS SOON AS WE FILLED UP, THE TRUCK WOULD NOT START! I SAW THAT MY CHECK ENGINE LIGHT WAS ON AND HAD TO ASK FOR A JUMPSTART TO GET IT STARTED AGAIN. AT ANOTHER TIME AND DATE AGAIN THE TRUCK WENT DEAD, I ASKED FOR A JUMPSTART AND THE VEHICLE WOULD NOT RESPOND. I NOW HAD TO BUY A NEW BATTERY BECAUSE THE CAR DAMAGED THE ORIGINAL BATTERY AND NOW WITH THE NEW BATTERY INSTALLED MY...

TRAILBLAZER SOUNDS LIKE A JET ENGINE WITH A LOT OF "WIND" NOISE. TOOK IT TO THE DEALER AND FOUND THAT THE FAN CLUTCH WENT BAD. NOT ONLY IS THE FAN CLUTCH FAILING ON MULTIPLE TRAILBLAZERS BUT CHEVY MADE THIS PART SO DYNAMIC THAT THE COST IS OUTRAGEOUS. ALSO, DUE TO THE FAN CLUTCH GOING BAD IT ALSO DAMAGES THE SERPENTINE BELT. *TR

EXHAUST MANIFOLD EXHIBITS CRACKS AND SMALL HOLES. EXHAUST FUMES ENTER THE CABIN. *TR

TL* THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHEN DRIVING SHE HEARS A HUMMING SOUND IN THE FRONT OF THE VEHICLE. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALERSHIP. THE CURRENT AND FAILURE MILEAGES WERE 56000.

THE FAN CLUTCH ON THIS PARTICULAR MODEL HAS A LONG HISTORY OF FAILURE, REPAIR MECHANIC HAS REPLACED MANY OF THESE UNITS. THIS FAILURE CAUSES A LOUD NOISE TO EMANATE FROM THE ENGINE AND RENDERS THE VEHICLE UNSAFE TO DRIVE DUE TO POTENTIAL ENGINE OVERHEARTING AND FAN CLUTCH LOCK-UP. *TR

2002 TRAILBLAZER SUDDENLY STARTED MAKING LOUD NOISE AS IF A JET AIRPLANE AND DELAYED TRANSMISSION SHIFTING, ALONG WITH LOSS OF POWER. TOOK IT TO MECHANIC AND THEY REPLACED FAN CLUTCH TO THE TUNE OF 730.00. *TR

TIE RODS, MULTIPLE TRANSMISSION MODULE PROBLEMS, AIRBAG, TAILLIGHTS, STOP, TURN SIGNAL REAR PROBLEM, ELECTRICAL/ WIRING,RADIO, HVAC, PRESSURE CONTROL,2 BATTERIES, 2 FAN CLUTCHES, AMONG OTHER PROBLEMS. *JB

SHARP TURN STEERING LOCKS UP. PASSENGER SEAT BELT GETS TIGHTER AND TIGHTER DOESN'T RELEASE PRESSURE. 4 WHEEL DRIVE NOT WORKING . TAPPING SOUND IN ENGINE. THE ONLY THING THE DEALER HAS DONE IS REPLACE POWER STEERING PUMP AND WITHIN 5 MILES IT WAS NOT WORKING AGAIN. *JB

2002 CHEVROLET TRAILBLAZER CAUGHT ON FIRE IN THE ENGINE COMPARTMENT. *MR WHILE ON THE HIGHWAY, THE VEHICLE WOULD NOT ACCELERATE, SUBSEQUENTLY SMOKE AND FLAMES HAD COME FROM THE HOOD WHICH WAS CAUSED BY THE DEFECTIVE MOTOR. THE CONSUMER REQUESTED REIMBURSEMENT FOR THE COST. *SC *JB

NUMEROUS PROBLEMS. CAR STALL 3X , BATTERY WENT OUT, WINDSHIELD WIPER WORN AND TAIL LIGHT OUT, CONSIDERED NOT SAFE. *BF THE VEHICLE WAS HIT IN THE REAR. THE DASH SYSTEM WENT OUT AND THE VEHICLE IDLED ROUGH. *SC

I HAVE A 2002 CHEVY TRAILBLAZER. IN RECENT MONTHS IT HAS SUDDENLY STALLED NUMEROUS TIMES, ON STREET DRIVING AT APPROXIMATELY 30 MPH, AND AT HIGHWAY DRIVING AT ABOUT 65 MPH. DURING THE HIGHWAY STALL THE CAR LOST POWER STEERING AND BRAKING CONTROL AND WAS FORTUNATELY STEERED OFF TO THE SIDE OF THE ROAD, WITH GREAT PHYSICAL EFFORT SINCE THE POWER STEERING WAS LOST. THE STALL CAUSES AN ABRUPT STOP OF THE CAR WITHOUT WARNING. I HAVE HAD THE CAR IN FOR TESTING AND REPAIR AT ROMANO CHEVEROLET IN SYRACUSE, NY AS WELL AS CURRY CHEVEROLET IN SCARSDALE, NY. NEITHER SHOP HAS BEEN ABLE TO DIAGNOSE OR REPAIR THE PROBLEM SINCE THE CAR'S COMPUTER IS NOT REGISTERING THE STALLS. THEY REPLACED THE FUEL FILTER SEVERAL WEEKS AGO BUT THE CAR SUDDENLY STALLED ON ME IN NORMAL STREET DRIVING AT 30 MPH A FEW DAYS LATER. I HAVE SPOKEN TO CHEVEROLET CUSTOMER...

WHILE DRIVING 40 MPH, THE ENGINE LIGHT ILLUMINATED, THEN THE VEHICLE STALLED. THIS CAUSED THE CONSUMER TO LOSE CONTROL OF THE VEHICLE, HITTING A WALL. THE CONSUMER HAD THE VEHICLE TOWED. THE DEALERSHIP TRIED TO REPAIR THE VEHICLE 7 TIMES, BUT DID NOT RESOLVE THE PROBLEM. THE AIR BAG ALSO FAILED TO DEPLOY DURING THE ACCIDENT. *AK THE PCM FAILED DUE TO A CIRCUIT INSIDE, FLUID LEAKED FROM THE POWER STEERING HOSE, THE ENGINE REVVED HIGH AND WAS LOUD WHEN THE VEHICLE WAS STARTED, THE CONSUMER SAW SPARKS UNDER THE HOOD FUSE BLOCK AT THE SAME TIME THE GAUGES FLUCTUATED AND SHORTED, THE RIGHT REAR TAIL LIGHTS WERE INOPERATIVE, AND THE FUEL GAUGE MADE A WHIRRING SOUND WHEN THE VEHICLE WAS STARTED. *SC *JB *CB

MY VEHICLE HAS BEEN IN THE SHOP FOR THESE REASONS AND MORE. FAULTY BACK LIGHT- DVD SYSTEMS. ON TOP OF ALL THESE IT HAS HAD THREE RECALLS IN THE NINE MONTHS I'VE OWNED IT. BOUGHT IT NEW!

IN NOVEMBER OF 2002, JN AUTOMOTIVE HAS REVERSED THE ODOMETER ON MY VEHICLE AND I BELIEVE THEY ARE IN VIOLATION OF THE FEDERAL ODOMETER LAW. I JUST WANT TO FIND SOME RESOURCES THAT WILL HELP ME RESOLVE THIS SITUATION.

IT APPEARS THE TRUCK IS SUFFERING FROM A MAJOR COMPUTER DEFECT. WITH ALL FUSES IN TACT, MANY FUNCTIONS NO LONGER WORK (REMOTE ACCESS, RADIO FUNCTIONS AFTER IGNITION TURN OFF, AUTOMATIC VOLUME INCREASE ON RADIO WHEN ACCELERATING). ADDITIONALLY, THE 4X4 TORQUE CONVERTER SWITCH DOES NOT LIGHT UP AND APPEARS TO BE NONFUNCTIONAL, THE AIRCONDITIONING QUITS AND AFTER ALLEGED REPAIR, STAYS ON ALL THE TIME REGARDLESS IF SET TO AIR OR VENT, THE REAR HATCH IS DEFECTIVE AND CAN'T BE OPENED, THE TAIL LIGHTS HAVE BURNT OUT THREE TIMES AND TWO HEADLIGHRS HAVE BURNT OUT.

ENGINE CHECK LIGHT CAME ON WHILE DRIVING. VEHICLE WAS TAKEN TO A DEALERSHIP BUT DEALERSHIP INDICATED THEY DIDN'T KNOW WHAT COMPONENT FAILURE CAUSED THE ENGINE CHECK LIGHT TO COME ON. DEALERSHIP SERVICED THE VEHICLE AND THE CONSUMER PICKED IT UP. THE ENGINE CHECK LIGHT CAME BACK ON WITHIN 2 WEEKS. VEHICLE WAS TAKEN BACK TO THE DEALERSHIP. WHEN THE CONSUMER PICKED THE VEHICLE UP THERE WAS A CLANGING NOISE WHILE DRIVING.*AK

G.M. SENT NOTICES TO COSTUMERS IN JUNE 2003 OF POSSIBLE ENGINE CYLINDER PROBLEMS IN EARLY 2002 CHEVROLET TRAILBLAZERS. THIS PBOBLEM IS QUITE SERIOUS AND HAS IN THE PISTONS, DEVELOP A KNOCK OR SLAP.THIS CAN AND DOES CAUSE DAMAGE TO CYL. WALLS AND OTHER INTERNAL PARTS. G.M.HAS OFFERED TO REPLACE PISTONS ONLY.THIS IS NOT WHAT SHOULD BE DONE IN A VEHICLE WITH ONLY 17,700 MILES.ITIS MY FEELING THE ENGINE SHOULD BE REPLACED .G.M. DOES NOT.I HAVE SPOKEN TO CHEVROLET CUSTOMER AND WAS TOLD ONLY PISTONS WOULD BE REPLACED.THIS WOULD INVOLVE NEARLY IF NOT COMPLETLY REBUILDING THE ENGINE.THIS IS NOT ACCEPTABLE TO ME AS I BELIVE I AN INTITLED TO HAVE THE ENGINE OF A NEW VEHICLE NOT A REBUILT ENGINE ACCEPTABLE FOR AN AGED VEHICLE. *AK

WHILE DRIVING AT 70 MPH ODOMETER DROPPED, CAUSING THE VEHICLE TO SLOW DOWN TO 10 MPH. DEALER NOTIFIED. *AK

PROBLEMS WITH AIR BAG DASH LIGHT, FAST ENGINE IDLE, AIR CONDITIONER, REAR HATCH INNER STRAP BROKE, ETC...*MR THE AIRBAG LIGHT WAS INTERMITTENT. THE SIR MODULE WAS REPLACED, AND THERE WAS POOR TERMINAL CONNECTION AT THE SIR WIRING HARNESS, AND WAS TRACED/REPAIRED ON THE LEFT SIDE IMPACT CONNECTOR AND THE CODES WERE CLEARED. THE ENGINE IDLED FAST(ESPECIALLY AT START UP, AND THE FUEL MILEAGE WAS 13 MPG. THE RESULTS OF THE EVALUATION AND REPAIRS WERE: PASSENGER IMPACT CONNECTOR WAS LOOSE(REPOSITIONED/CONNECTED), IDLE WITHIN SPECIFICS, THE EMBLEM HAD FALLEN OFF, THE REAR HATCH INNER STRAP HAD BROKEN, THE TRANSMISSION SEEMED TO TAKE LONG TO SHIFT INTO GEAR(HAPPENED SOMETIMES WHEN COLD), AND THE PCM NEEDED TO BE REPROGRAMMED(J6355 POWER TRAIN CONTROLLER PCM). THERE WAS A THUMPING SOUND IN THE REAR DIFFERENTIAL WHEN SHIFTED, THE A/C WOULD BLOW OUT COLD AIR WHEN THE A/C INDICATOR WAS OFF, HOT AIR WOULD COME OUT OF THE DEFROSTER...

ENGINE STALL - TRUCK STALLED AND ALL LIGHTING AND COMPONENTS WENT DEAD WHILE SLOW TO STOP AT AN INTERSECTION. THE TRUCK COULD NOT BE RE-STARTED. AFTER 10 MINUTES, THE TRUCK STARTED AGAIN AND WAS ABLE TO DRIVE ON. SUBSEQUENT ATTEMPTS TO START THE TRUCK FAILED RESULTING IN IT BEING TOWED TO THE DEALER. THE DEALER HAD TO REPLACE ONE OF THE COMPUTERS IN THE TRUCK AND IT HAS BEEN FINE EVER SINCE. I HEARD ABOUT THE INVESTIGATION FOR THE ENVOY AND BRAVADA BUT NOT THE TRAILBLAZER. MY TRUCK IS A TRAILBLAZER AND DID EXPERIENCE THE SAME PROBLEMS AS THE TWO SISTER TRUCKS THAT SHARE THE SAME MECHANICALS.

THE ENGINE MADE A RUMBLING/CLICKING SOUND, SHUT OFF SUDDENLY, THE POWER STEERING HAD GONE OUT, AND THE POWER BRAKES FAILED. THE DEALER DETERMINED THAT THE ENGINE NEEDED TO BE REPLACED. TS
