2004 CHEVROLET TRAILBLAZER Engine And Engine Cooling Problems

I BOUGHT MY VEHICLE AT A DEALERSHIP IN 2010. I DO NOT REMEMBER THE EXACT DATE BUT IT STARTED HAVING PROBLEMS SHORTLY AFTER. THE FIRST THING THAT HAPPENED WAS ALL MY GAUGES STOPPED WORKING EXCEPT MY SPEEDOMETER. IN 2012 I WAS DRIVING AND AT TWO DIFFERENT OCCASIONS WITHIN A DAY APART, WHILE I WAS TURNING INTO A PARKING LOT OR GAS STATION, MY VEHICLE WOULD SHUT OFF. I TOOK IT TO AUTO ZONE TO HAVE ONE OF THOSE FREE TESTS DONE AND NOTHING WAS SHOWING UP AS ABNORMAL. AROUND 2013 MY VEHICLE STARTED MAKING A REAL HIGH PITCH SQUEALING SOUND DURING START UP AND WHILE DRIVING. I TOOK MY CAR INTO SINCE IT NEEDED A NEW WATER PUMP AND THEY SAID THAT THE HIGH PITCH SOUND COULD BE FIXED BUT WASN'T A SAFETY CONCERN. IN 2014 JUST A FEW MONTHS AGO, AGAIN I WAS PULLING INTO A GAS STATION AND...

OTHER DRIVERS NOTIFIED OWNER/DRIVER THAT VEHICLE WAS ON FIRE.

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILERBLAZER. THE CONTACT STATED THAT THE SERVICE ENGINE LIGHT ILLUMINATED WHILE DRIVING. THE VEHICLE WAS TAKEN TO A MECHANIC WHO STATED THAT THE FAILURE CODE INDICATED THAT THE THERMOSTAT WAS DEFECTIVE. WITHIN A FEW DAYS ALL OF THE LIGHTS ON THE INSTRUMENTAL PANEL ILLUMINATED. THE VEHICLE WAS TAKEN BACK TO THE MECHANIC AND THERE WAS NO DIAGNOSTIC CODE DISPLAYED. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WASN'T REPAIRED. THE FAILURE AND THE CURRENT MILEAGES WERE 74,393.

INSTRUMENT CLUSTER WENT DEAD - HEATER THERMOSTAT WENT OUT AND DRIVERS SIDE IS STUCK ON HEAT AND WON'T SHUT OFF - SENDING THE TRAILBLAZER TO OBAMA AND GOV.'T MOTORS - NO CHANCE IT WILL EVER GET FIXED SINCE OBAMA BOUGHT OFF THE UNION! *TR

SERVICE ENGINE SOON LIGHT WAS ON AFTER COMPLETING A DIAGNOSTIC TEST AT A LOCAL DEALER THEY SAID THE MALFUNCTION WAS THE SECONDARY AIR INJECTION(AIR PUMP) CODE P0410. THEY SAID THE REASON THESE GO OUT IS BECAUSE OF AN ENGINEERING DEFECT AND THE WAY THEY ROUTED THE HOSES INSTEAD OF AIR FLOWING THROUGH IT CAUSES WATER TO ACCUMULATE THEREFORE MAKING THE MOTOR IN THE AIR PUMP TO GO BAD. SO WHILE CHANGING OUT THIS BAD AIR PUMP THERE WAS SO MUCH WATER THAT HAD ACCUMULATED IT ACTUALLY CAUSED THE LIGHT TO BLOW WHICH COULD HAVE CAUSED THE MECHANIC TO BE ELECTROCUTED! *TR

I WAS TRAVELING ON THE HIGHWAY WHEN I HERD A RATTLING SOUND COMING FROM THE ENGINE, GOT OFF THE HIGHWAY AND PULL INTO A STATION. CALL THE TOW COMPANY TO TOW IT TO MY MECHANIC HE SAID THE WATER PUMP BEARINGS BROKE AND THE FAN STOP TURNING SINCE BOTH ARE CONNECTED TOGETHER, HE SAID THE ENGINE MIGHT BE DAMAGE POSSIBLE DUE TO OVERHEATING. THERE WAS NO WARNING OF OVER HEATING ON THE GAGE, WATER DID NOT LEAK FROM THE PUMP. I CALL GM AND THEY TOLD ME TO TOW IT TO THE DEALER FOR DIAGNOSE AND THEY WERE CONSIDER MY CLAIM AFTER THE DIAGNOSE CHECK; THEY KNEW MY WARRANTY JUST EXPIRED IN JULY. I TOLD THEM THERE WAS KNOW WARNING OF ANY KIND EVERYTHING WAS FIND WATER PUMP BEARINGS JUST BROKE ALONG WITH THE FAN CLUTCH THIS SAMPLE PROBLEM CAUSE THE WHOLE ENGINE TO GO BAD. IF THERE IS GOING...

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND THE CONTACT TOOK THE VEHICLE TO THE DEALER; HOWEVER, THEY COULD NOT DETERMINE THE CAUSE OF THE FAILURE.

WE HAVE HAD A PROBLEM WITH OUR SERVICE ENGINE LIGHT COMING ON WITHIN THE PAST 2 WEEKS IN OUR 2004 TRAILBLAZER. AFTER GETTING IT DIAGNOSED IT IS BEING CAUSED BY THE FAN SPEED BEING TOO HIGH. AFTER DOING SOME RESEARCH THIS VEHICLE HAS HAD NUMEROUS REPAIRS FOR THE SAME ISSUE. WHY HAS GM NOT WARRANTED THIS!? WE HAVE GOTTEN CRAPPY SERVICE FROM THE DEALERSHIP AND WHILE OUR VEHICLE IS OUT OF WARRANTY NOW IT IS PAID FOR OUR WE WOULD HAVE GOTTEN RID OF IT ALREADY. *TR

MY 2004 TRAILBLAZER HAS BEEN HESITATING AND STALLING FOR ABOUT A YEAR AND A HALF. THIS OCCURS DAILY SOMETIMES SEVERAL TIMES A DAY. THERE ARE TIMES THE VEHICLE STALLS AND DIES. NO ONE HAS BEEN ABLE TO DETERMINE THE CAUSE. ABOUT SIX MONTHS AGO THE HEADLIGHTS QUIT. SINCE HAS BEEN REPAIRED. LAST WEEK THE DASH BOARD INSTRUMENTS QUIT WORKING, FUEL GUAGE AS WELL. *TR

OUR 2004 CHEVROLET TRAILBLAZER WITH APPROX 40,000 MILES CAUGHT FIRE WHILE DRIVING APPROXIMATELY 40 MPH. WE NOTED SMOKE BEHIND THE CAR AND BEFORE WE COULD PULL OVER OTHER DRIVERS WERE YELLING TO US THAT THE CAR WAS ON FIRE. WE IMMEDIATELY GOT TO SIDE OF ROAD, TURNED OFF ENGINE AND A LARGE FIRE WAS COMING FROM THE HOOD. A GOOD SAMARITAN RAN UP WITH A FIRE EXTINGUISHER AND PUT OUT THE FIRE THAT WAS APPROX 4 FEET HIGH FROM THE HOOD. ALL PASSENGERS SAFELY EXITED THE CAR AS SOON AS STOPPING AND DUE TO THE FIRE BEING EXTINGUISHED QUICKLY NO OTHER DAMAGE WAS DONE. THIS VEHICLE WAS RUNNING FINE WITH NO RECENT ISSUES OR SERVICE ON THE VEHICLE PRIOR TO THIS EVENT. WE HAVE NEVER HAD THE CAR SERVICED BY ANYONE OTHER THEN CHEVROLET DEALERSHIPS. WE WERE INFORMED BY THE TOW TRUCK COMPANY THAT THEY HAVE MANY 2004 CHEVY TRAILBLAZERS...

AFTER COMING TO A STOP THE 2004 CHEVROLET TRAILBLAZER EXT STALLED. I BROUGHT IT TO THE SANTA MARIA HOME MOTORS TWICE. THE FIRST TIME THEY ADDRESSED THE PROBLEM WITH THE 30,000 MILE SERVICE AND SAID SEE IF IT HAPPENS AGAIN. THE TRAILBLAZER STALLED AGAIN SO THEY REPROGRAMED THE COMPUTER AND CHARGED ME $85 TO DO THIS. TODAY MY WIFE WAS DRIVING THE TRAILBLAZER AND IT STALLED AGAIN. LIKE I HAVE TOLD THE SERVICE AGENT AT HOME MOTORS I WA S AFRAID THAT THIS WILL HAPPEN WHEN MY WIFE AND CHILDREN WERE CROSSING THE TRAIN TRACK, AND THEY COULD BE KILLED BY AN ONCOMING TRAIN. I WILL BRING THE TRAILBLAZER BACK TO THE DEALER TOMORROW. *AK

I HAVE HAD MY TRAIL BLAZER FOR 1 YR AND 1 MONTH. IN THAT TIME I HAVE HAD TO REPLACE FRONT AND BACK PADS AND ROTORS, BALL JOINTS, CATALYTIC (SP) CONVERTER, AND NOW THEY JUST TOLD ME I HAVE TO REPLACE THE HEAD GASKET ON THE MANIFOLD. WHAT THE HELL IS GOING ON WITH THIS VEHICLE. I NO LONGER FEEL SAFE DRIVING IT. THE OTHER DAY THE RADIO JUST STOPPED PLAYING AND THEN THE SERVICE 4 WHEEL DRIVE LIGHT CAME ON. *NM

MY 2004 CHEVROLET TRAILBLAZER INTERMITTENTLY STALLS OUT IN TRAFFIC. IT HAS BEEN TO THE DEALERSHIP 5 TIMES FOR REPAIR, WITH NO RESULTS. THE DEALER HAS ACTUALLY BEEN ABLE TO REPRODUCE IT, AND HAS REPLACED ITEMS, BUT GM IS UNABLE TO ISOLATE THE PROBLEM. *JB

ON 5 SEPARATE OCCASIONS, THE ENGINE ON MY 2004 TRAILBLAZER HAS STALLED WHILE IN TRAFFIC. 1 TIME, THE ENGINE STALLED WHEN I APPLIED THE BRAKES; EVERY OTHER TIME, THE ENGINE STALLS WHILE AT IDLE. I HAVE TAKEN IT INTO THE DEALERSHIP REPEATEDLY, AND THEY HAVE BEEN UNABLE TO DUPLICATE BUT NOT FIX THE PROBLEM. THEY HAVE REPLACED THE MANIFOLD PRESSURE VALVE AND CLEANED THE THROTTLE PLATES, BUT THE PROBLEM STILL PERSISTS. *JB

DT: THE CONTACT STATE WHILE DRIVING THE VEHICLE STALLED WITHOUT WARNING. SHE WAS ABLE TO RESTART THE VEHICLE. THE CONTACT TOOK THE VEHICLE TO THE DEALERSHIP FOR INSPECTION. THE DEALERSHIP INFORMED HER IT WAS THE CRANK SHAFT SENSOR. SHE CONTACTED THE MANUFACTURER, AND THEY INFORMED HER THAT IT WAS DUE TO A DEFECTIVE SENSOR. NO REPAIRS HAVE BEEN MADE AT THIS TIME.*AK

DT: 2004 CHEVROLET TRAILBLAZER. IN JANUARY, THE CONSUMER WAS ON THE FREEWAY AND THE VEHICLE IT LOST POWER. THE CONSUMER PULLED OVER AND RESTARTED IT AFTER SITTING FOR A FEW MINUTES. THE ENGINE LIGHT WAS STILL ON, SO THE VEHICLE WAS TAKEN TO A DEALERSHIP AND IT HAD A DEFECTIVE CHIP. THE PROBLEM HAPPENED AGAIN IN MAY AND THIS PAST JULY 4, THE CONSUMER WAS GOING OUT OF TOWN. THE CHECK ENGINE LIGHT CAME ON AGAIN AND THE ENGINE WAS LOSING POWER. THEY CALLED THE TOLL FREE NUMBER AND WERE INFORMED THAT THEY WOULD HAVE TO WAIT UNTIL AFTER THE HOLIDAY. WHEN THE VEHICLE WAS TAKEN IN, IT WAS FOUND THE OXYGEN SENSOR WAS RESPONDING SLOWLY. *JB

WHILE DRIVING 40 MPH ABS LIGHT AND THE BRAKE LIGHT CAME ON. THIS CAUSED THE VEHICLE TO STALL. THE VEHICLE WAS TOWED TO THE CONSUMER'S DAUGHTER HOUSE. *AK *SC

MAJOR ELECTRICAL PROBLEMS INSIDE THE VEHICLE. I HAVE OWNED IT LESS THAN A YEAR.THE VEHICLE HAS BEEN IN THE SHOP TWICE IN THE PAST TWO WEEKS. EXITING THE FREEWAY THE I HAD A COMPLETE POWER FAILURE. THE VEHICLE COMPLETELY STOPPED AND LOCKED UP AND THERE WAS A SEMI TRUCK BEHIND ME! MY VEHICLE WAS MOVING AND IN "DRIVE" WHEN THIS HAPPENED. I HAD TWO OF MY TODDLERS IN THE CAR WITH ME! THE VEHICLE WAS TAKEN INTO A LOCAL DEALER AND UNFORTUNATELY THEY COULD NOT FIND ANYTHING WRONG WITH IT. APPARENTLY, WHEN THE VEHICLE IS RESTARTED IT ERASES THE CODES IN THE ENGINE AS TO WHAT CAUSED THE PROBLEM. WELL, IT HAPPENED TO ME AGAIN THIS EVENING. SAME PROBLEM. THIS WILL BE MY 5TH TIME OF BRINGING THIS VEHICLE IN FOR ELECTRICAL PROBLEMS IN LESS THAN A YEAR. I ONLY HAVE 9400 MILES ON THE VEHICLE AND BOUGHT IT BRAND...

ON THE 1-2 AND 2-3 SHIFTS THERE IS A RATTLING SOUND (OR LIGHT KNOCKING) SOUND COMING FROM THE ENGINE. IT SOUNDS LIKE NOISY LIFTERS. IT OCCURS MOST OF THE TIME, BUT NOT ALL OF THE TIME.*AK

WHILE DRIVING VEHICLE STALLED. THE CONSUMER RESTARTED VEHICLE,AND HAD THE VEHICLE TOWED TO THE DEALER FOR INSPECTION. THE MECHANIC COULD NOT DUPLICATE THE PROBLEM. THE CONSUMER INFORMED THE MECHANIC THAT THIS PROBLEM OCCURRED MORE THAN ONCE. *AK THERE WAS NO WARNING. SC

ENGINE STALLED IN TRAFFIC AND IDLES ROUGH ON STARTUP. DEALER REPROGRAMMED IDLE CONTROL MODULE. ENGINE SURGES AND SHAKES UNDER A LOAD FROM POWER STEERING OR ALTERANTOR. DEALER CLEANED THROTTLE BODY (ONLY 4800 MILES) AND FOUND LARGE LEAK AT EVAP VAPOR PIPE. CONTINUED TO HAVE PROBLEM. DEALERSHIP CONTACT GM FOR HELP. GM REPLIED THAT "4.2 LITER MOTORS HAVE AN INHERENT VIBRATION AT THAT SPEED." GM TECHNICAL ASSISTANCE ALSO STATED "ENGINE SURGE UNDER IS NORMAL UNDER LOAD BY DESIGN." CAR IS TICKING TIME BOMB FOR ANOTHER STALL IN TRAFFIC AND DAILY ENDANGERS MY FAMILY. *LA

VEHICLE LOOSES POWER AND THE ENGINE WILL NOT GO ABOVE 2000 RPM. THIS IS NOT FAST ENOUGH TO GO THROUGH AN INTERSECTION WITHOUT BEING HIT OR SIDE SWIPED. PROVIDE FURTHER DETAILS. *LA
