2004 Chevrolet Trailblazer EXT complaints

TL* THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER EXT. WHILE THE CONTACT WAS DRIVING APPROXIMATELY 45 MPH, BOTH THE DRIVER AND PASSENGER SIDE AIR BAGS DEPLOYED WITHOUT IMPACT. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE BOTH AIR BAGS WERE BEING REPLACED. THE MECHANIC WAS UNABLE TO DETERMINE THE CAUSE OF FAILURE. THE MANUFACTURER WAS NOT NOTIFIED OF THE MALFUNCTION. THE APPROXIMATE FAILURE MILEAGE WAS 154,654.

TL* THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. WHILE THE VEHICLE WAS PARKED, THE CONTACT NOTICED A SIGNIFICANT AMOUNT OF FUEL LEAKING ONTO THE GROUND. THE CONTACT INSPECTED THE VEHICLE AND DISCOVERED THE FUEL TANK WOULD NEED TO BE REPLACED. THE MANUFACTURER ISSUED A VOLUNTARY RECALL PERTAINING TO THE FUEL TANK FILLER NECK. THE DEALER WAS NOTIFIED AND THEY STATED THE VIN WAS INELIGIBLE UNDER THE RECALL DEFECT. THE MANUFACTURER WAS NOT MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 88,000.

NOTICED GASOLINE ODORS INSIDE THE VEHICLE ON OCT. 2011. PERSONAL AUTO MECHANIC TOLD ME LAST WEEK THAT THERE'S A CRACK ON THE FUEL FILL NECK AREA WHERE THE GAS NOZZLE IS INSERTED. *TR

THE SPEEDOMETER IS NOT REGISTERING THE CORRECT SPEED, JUMPS AROUND WHILE DRIVING AND HAS AFFECTED THE CRUISE CONTROL. I FOUND THAT THIS ISSUE IS THE SAME AS NHTSA ITEM # 10023585 FOR MOST SIMILAR GM VEHICLES, BUT FOR SOME REASON, THIS FAMILY OF GM TRUCKS WAS NOT INCLUDED IN THE REPORTED ISSUE. WHEN THE VEHICLE IS STOPPED, THE SPEEDOMETER NEEDLE DROPS WELL BELOW 0 AND THEN JUMPS AROUND WHEN THE VEHICLE STARTS MOVING. BASED ON CHECKS WITH OUR GPS, THE SPEEDOMETER IS OFF BY AS MUCH AS 20 MPH. *TR

THIS VEHICLE HAD BEEN PARKED IN THE DRIVEWAY FROM 7:45 PM, (AUGUST 10, 2011). I WAS AWAKENED AT APPROX. 3:55 AM ON 8-10-2011 BY HEARING A MUFFLED BOOM. AT 4:00 AM (AUG. 11, 2011) I HEARD A LOUD BANG TYPE NOISE. I IMMEDIATELY GOT UP AND WENT TO INVESTIGATE. I WENT OUTSIDE AND FOUND MY 2004 TRAILBLAZER (EXT) ON FIRE FROM THE ENGINE BAY AND JUST BEGINNING TO FLAME INSIDE THE VEHICLE'S PASSENGER COMPARTMENT AT THE DASHBOARD..IT ONLY TOOK MINUTES BEFORE THE VEHICLE WAS FULLY INVOLVED. THE FIRE BEGAN IN THE ENGINE BAY. THE FIRE MARSHALL REPORT IS STILL PENDING AND I WAS INFORMED IT WOULD TAKE 6 TO 8 WEEKS BEFORE IT WAS AVAILABLE. APPROX. TWO TO THREE MONTHS PRIOR, I TOOK THE VEHICLE TO A REPAIR GARAGE TO FIX THE LOW BEAM HEADLIGHTS (THEY HAD FAILED AND CHANGING THE BULBS WAS NO HELP. IT TURNED OUT THAT IT WAS A FAILED RELAY, WHICH WAS REPLACED. IT WAS A COUPLE OF WEEKS LATER THAT I HAD TO REPLACE THE VEHICLE'S BATTERY AS IT HAD GONE DEAD AND WOULD NOT TAKE A CHARGE. THE OLD BATTERY WAS ABOUT THREE YEARS OLD. THERE WERE NO OTHER BATTERY/HEADLIGHT ISSUES AFTER THESE REPAIRS. NO TOOLS OR OTHER PARTS WERE DROPPED INTO THE ENGINE BAY, OR LEFT IN THE BAY. I WAS AN AIRCRAFT MECHANIC AND OLD HABITS OF KEEPING RACK OF MY TOOLS NEVER DIE AND ALL TOOLS USED WERE ACCOUNTED FOR. THE ROADS WERE DRY WHERE IT WAS DRIVEN THERE WAS NO RAIN AT THE HOUSE ALL NIGHT. I REPORTED THIS TO CHEVROLET THAT DAY. AS A RESULT OF THE FIRE, THE EAVES OF THE HOUSE OVER THE GARAGE CAUGHT FIRE, MY WIFE, SON AND MYSEL

THE RPM GAUGE, BATTERY GAUGE AND THE FUEL GAUGE STOPPED WORKING. FIRST THE RPM GAUGE STOPPED AND THEN ABOUT A YEAR LATER THE BATTERY GAUGE STOPPED AND LAST WAS THE FUEL GAUGE THAT STOPPED. THE FUEL GAUGE STOPPED WORKING JUST A COUPLE OF WEEKS AFTER THE BATTERY GAUGE. I AM ALSO HAVING PROBLEMS WITH THE DAYTIME RUNNING LIGHTS NOT STAYING ON PERIODICALLY. THE DAYTIME RUNNING LIGHTS WILL GO OUT ABOUT TWICE A YEAR AND MAINLY AT NIGHT. *KB

THE INSTRUMENT CLUSTER STOPPED WORKING, ONLY THE TEMP GAUGE AND THE FUEL GAUGE WORKS. THE SPEEDOMETER, TACHOMETER, OIL PRESSURE GAUGES DO NOT WORK. I BELIEVE GENERAL MOTORS NEEDS TO ISSUE A RECALL ON THIS AS THIS IS A COMMON PROBLEM WITH THESE VEHICLES. *KB

THE EXT. MANIFOLD ON MY 2004 TRL BLAZER HAS A LEAK IN THE MAIFOLD BODY. THE VEHICLE HAS APPROX. 120000 MILES ON IT. THIS SHOULD BE A RECALL ITEM FOR MANUFACTURING DEFECT, BUT GM HAS NOT AS OF YET, ISSUED A RECALL. IT IS A COSTLY REPAIR, AS WELL AS A SAFETY CONCERN, GIVEN THAT THE EXHAUST FUMES CAN ENTER THE PASSENGER COMPARTMENT OF THE VEHICLE. I HAVE OWNED MANY GM VEHICLES OVERTIME, AND NEVER SEEN THIS BEFORE. *TR

SPEEDOMETER GOES COMPLETELY OUT, FALLING BELOW ZERO WHILE TRAVELING ON ROAD, TYPICALLY AFTER CRUISE CONTROL HAS BEEN USED, MULTIPLE WARNING LIGHTS FLASH WHILE ONSTAR AND COMPUTER SHOWING NO CODES AFTER 4X4 USED. UNABLE TO DIAGNOSE PROBLEMS BECAUSE PROBLEM IS INTERMITTENT AND AFTER VEHICLE PARKED FOR SEVERAL HOURS PROBLEM IS GONE. OCCURS ABOUT ONCE A WEEK. HAS CAUSED SEVERAL INSTANCES OF BEING UNABLE TO DETERMINE HOW FAST YOUR TRAVELING. 2004 CHEVY TRAILBLAZER EXT LT 4X4 I6 ENGINE. *TR

THE FUEL TANK IS LEAKING. THE FILL TUBE SEPARATED FROM THE TANK AND IS LEAKING FUEL ONTO THE TANK. THERE IS A STRONG FUEL ODOR AS WELL. CALLED CHEVROLET THEY STATED THAT VEHICLES ARE ONLY BEING REPAIRED FOR THIS ISSUE IN NORTHERN, EASTERN AND MIDWESTERN STATES. STATED THEY WILL NOT FIX MY ISSUE THOUGH IT HAS THE SAME ISSUES COVERED UNDER THE SPECIAL COVERAGE, DUE TO MY GEOGRAPHIC LOCATION. *TR

MY 2004 CHEVY TRAILBLAZER HAS AN INSTRUMENT PANEL THAT STOPPED WORKING. I FEEL THIS IS VERY UNSAFE BECAUSE I DON'T KNOW HOW FAST I AM GOING, WHAT MY OIL PRESSURE IS, THE TEMPERATURE OF MY CAR, OR HOW MUCH GAS I HAVE. I CONTACTED A REPAIR SHOP BUT IT IS OVER $1000 TO REPLACE THE PANEL AND THERE IS NO GUARANTEE THAT THIS WON'T HAPPEN AGAIN. APPARENTLY I AM BEING TOLD THIS IS A PROBLEM THAT IS VERY COMMON IN THIS YEAR AND MAKE BUT THERE IS NOT A RECALL FOR IT. I DON'T UNDERSTAND WHY. *TR

2004 CHEVY TRAILBLAZER DASH CLUSTER. I HAVE 43,000 MILES ON MY VEHICLE AND THE DASH GAUGES WENT OUT. THEY STARTED TO WORK AFTER ABOUT 10 MINUTES OF DRIVING AND NOW THEY COME ON ONLY ABOUT 1 OUT OF 4 TRIPS. I SEARCHED THE INTERNET AND FOUND A LOT OF OWNERS COMPLAINING ABOUT THE SAME PROBLEM. WHY IS THIS NOT A RECALL? PLEASE HELP IF YOU CAN. *TR

I OWN A 2004 CHEVY TRAILBLAZER. I AM HAVING CONSTANT PROBLEMS WITH THE GAS GAUGE INDICATING THAT EITHER THERE IS LESS GAS THEN ACTUAL, OR MORE GAS THEN ACTUAL. I KNOW THERE IS AN INVESTIGATION GOING ON WITH THESE VEHICLES BUT ONLY FOR THE YEARS 2005-2007, MINE IS A 2004. THIS INVESTIGATION SHOULD ALSO INCLUDE THIS YEAR SINCE THE SAME PROBLEMS ARE HAPPENING. *TR

INSTRUMENT CLUSTER FAILURE STARTING WITH TACHOMETER THEN SPEEDOMETER. AT 90,000 +/- MILES ALWAYS HAVE INTERMITTENT / OBVIOUSLY WRONG INFO FROM TACHOMETER (USUALLY PAST 7000) AND SPEEDOMETER (ALWAYS READS <20 MPH). *TR

ON OUR 2004 CHEVROLET TRAILBLAZER THE ONLY GAUGE THAT WORKS ALL THE TIME IS THE SPEEDOMETER. MOST OF THE OTHER GAUGES ' INCLUDING THE FUEL GAUGE, TACHOMETER, ETC, ' DON'T WORK AT ALL! THE COOLANT TEMPERATURE GAUGE WORKS ONLY SPORADICALLY. IN ADDITION, THE DASHBOARD WARNING LIGHTS ALSO DO NOT FUNCTION PROPERLY: THE AIRBAG LIGHT, ABS BRAKES LIGHT, AND 'CHECK ENGINE' LIGHT UNPREDICTABLY REMAIN LIT ' NOT ALWAYS AT THE SAME TIME - SOMETIMES FOR DAYS AT A TIME WHEN THE CAR IS ON. THERE IS NO PATTERN AS TO WHEN THE LIGHTS WILL STAY ON AND WHEN THEY WILL REMAIN OFF. I AM REPORTING THESE PROBLEMS TO YOU SINCE I READ THAT YOU ARE INVESTIGATING THIS SAME PROBLEM IN 2005 THROUGH 2007 TRAILBLAZERS. I FEEL YOU SHOULD EXPAND YOUR RESEARCH TO INCLUDE 2004 TRAILBLAZERS. *TR

ON SEVERAL OCCASION OVER THE PAST YEAR MY FUEL GAUGE IN MY 2004 CHEVROLET TRAILBLAZER LT HAS READ INACCURATELY LEADING TO BREAKING DOWN DUE TO THE VEHICLE RUNNING OUT OF GAS WHILE THE GAUGE WAS STILL READING AT LEAST 1/4 TANK MOMENTS BEFORE THE ENGINE STALLS. ON ALL OCCASIONS I WAS DRIVING ON THE FREEWAY THE GAUGE SHOWED 1/4 TANK AND THEN ALL OD A SUDDENLY DROPPED TO E WITH THE FUEL WARNING LIGHT COMING ONE. WITHIN A FEW MILES OF THIS SUDDEN DROP AND THE WARNING LIGHT COMING ON THE ENGINE WOULD STALL DUE THE VEHICLE BEING OUT OF GAS. I HAVE COMPLAINED TO MY LOCAL DEALER ON SEVERAL OCCASIONS AND ALL THEY HAVE OFFERED TO ME IS TO REPLACE THE SENDING UNIT, WHICH IN THIS MODEL IS INTEGRATED WITH THE FUEL PUMP AT THE COST OF ALMOST $800. THIS SEEM WRONG TO ME. NOW THAT I HAVE READ THAT THIS SEEMS TO BE A PROBLEM ON THESE TYPES OF VEHICLES I AM EVEN MORE UPSET THAT THE LOCAL DEALERSHIP TOLD ME MY ISSUE IS AN ISOLATED ISSUE AND THEY HAVE NEVER HEARD OF ANY PROBLEMS WITH THE FUEL GAUGES IN THESE VEHICLES. *TR

I OWN A 2004 CHEVY TRAILBLAZER. I PURCHASED IT USED FROM A DEALER IN DECEMBER OF 2010. I NOTICE SINCE I HAVE OWNED IT THAT THERE IS SOMETHING WRONG WITH THE GAS GAUGE. IT WILL SHOW A DECENT AMOUNT OF GAS IN THE TANK THEN BY THE TIME I GET OUT OF MY DRIVEWAY IT IS SHOWING EMPTY. IT WILL GO UP AND DOWN ALL THE TIME. I KNOW I AM NOT OUT OF GAS, BECAUSE I MAKE SURE TO PUT GAS IN EVERY DAY BECAUSE I AM NOT SURE WHAT IS IN THE TANK BECAUSE OF THIS PROBLEM. I WAS GOING TO TAKE IT TO A MECHANIC TO HAVE THEM LOOK AT IT AND FIX THE PROBLEM. SINCE SEEING THAT AN INVESTIGATION IS BEING DONE FOR THE SAME EXACT PROBLEM, I DECIDED TO WRITE HERE FIRST. I AM REQUESTING THAT THE YEARS INVESTIGATED ALSO INCLUDED 2004, SINCE IT IS THE SAME PROBLEM THAT IS BEING INVESTIGATED BY YOUR AGENCY. *TR

NOT SURE WHAT TO FILE THIS UNDER, SO I PUT IT UNDER FUEL SYSTEM, GASOLINE. SAME DAY I WAS HAVING PROBLEMS WITH SPEEDOMETER I WAS HAVING PROBLEMS WITH THE GAS GAGE. THE ARROW WOULD GO WAY PAST FULL, WHEN I KNEW I ONLY HAD ABOUT HALF A TANK. THE GAS GAGE HAS BEEN ACTING UP EVER SINCE, I JUST HAVE TO KEEP TRACK OF MY MILEAGE TO KNOW WHEN TO FILL IT UP. HAVE NOT HAD THE PROBLEM FIXED YET. *TR

SPEEDOMETER WAS READING 90MPH ON A TRIP AND CARS WERE PASSING ME, WHEN I STOPPED THE SPEEDOMETER READ 35MPH STANDING STILL. IT DID THIS FOR ABOUT 3 DAYS, THEN WENT BACK TO NORMAL. THE OTHER DAY COMING HOME FROM A TRIP IT SEEMED LIKE IT WAS ACTING UP AGAIN, BUT MY HUSBAND WAS DRIVING, HE THOUGHT IT WAS ACTING UP TOO. IT IS BACK TO NORMAL, HAVEN'T DONE ANYTHING ABOUT IT. *TR

NOT SURE WHAT TO FILE THIS UNDER, SO I PUT IT UNDER UNKNOWN AND OTHER. ABOUT 4 MONTHS AGO MY SERVICE ENGINE SOON LIGHT CAME ON. IT STAYED ON FOR A FEW DAYS THEN WENT OFF, A FEW DAYS LATER IT WAS BACK ON, THEN A FEW DAYS LATER WENT OFF, THEN IT CAME ON FOR A LONGER PERIOD OF TIME AND DO THE SAME THING, EVENTUALLY IT STAYED ON. TOOK IT TO THE CHEVY DEALERSHIP WHERE I BOUGHT IT AND THEY SAID THE GAS TANK HAD A CRACK IN IT AND NEEDED TO BE REPLACED. SAID IT WAS PROBABLY FROM THE GAS NOZZLE HITTING THE TANK WHEN FILLING IT UP. DON'T SEE HOW THAT IS POSSIBLE, WHEN IT IS ONLY ME OR MY HUSBAND FILLING IT UP & HOW HARD WOULD YOU HAVE TO HIT IT FOR IT TO CRACK? HAD IT REPLACED THE NEXT MONTH. NOW THE SERVICE ENGINE SOON LIGHT IS DOING THE SAME THING. HAVEN'T TAKEN IT BACK IN YET. *TR

2004 CHEVROLET TRAILBLAZER EXT. RPM GAUGE STOP WORKING AND THEN NOW THE RPM AND SPEEDOMETER IS NOT WORKING. I FOUND A NUMBER OF REPORTS FROM OTHERS ONLINE STATING THAT THEIR RPM AND SPEEDO ALSO STOPPED WORKING. I HAVE SEEN NO RECALLS ON THIS PROBLEM. I HAVE NO IDEA HOW FAST I'M TRAVELING. *TR

HEADLIGHTS WILL NOT WORK. DAYTIME RUNNING LIGHTS DON'T WORK. THE ISSUE WAS ADDRESSED BY CHEVY DEALERSHIP. THIS IS A ON GOING PROBLEM. OTHER CHEVY AND GM SUV HAD BEEN RECALLED FOR THIS ISSUE HOWEVER THIS MODEL WAS NOT INCLUDED WITHIN THE RECALL. *TR

THE SPEEDOMETER IN MY 2004 CHEVY TRAILBLAZER EXT COMPLETELY STOPPED WORKING ABOUT 6 MONTHS ABOUT. WE HAVE BEEN DEALING WITH THIS ISSUE AND JUST PRAYING WE DO NOT GET A SPEEDING TICKET. NOW THE CHECK ENGINE LIGHT CONTINUES TO STAY ON EVEN WHEN RESET. I AM NOT BEING TOLD I NEED TO CHECK THE FUSE WHICH WAS UNSUCCESSFUL. I CAN ONLY IMAGINE IF THE NEXT THING TO GO WILL BE ALL THE ELECTRONICS IN THE DASHBOARD. THIS SERIOUSLY NEEDS TO BE A RECALL ITEM! *TR

I AM HAVING MULTIPLE INSTRUMENT CLUSTER PROBLEMS ON MY 2004 CHEVY TRAILBLAZER. THEY HAVE DONE RECALLS ON EVERY TYPE OF CHEVY TRUCK BUT THE TRAILBLAZER. WHY NOT THE TRAILBLAZER AS WELL? I HAVE BEEN READING FORUMS AFTER FORUMS AND COMPLAINTS ABOUT THE SAME THING AND GM REFUSES TO DO ANYTHING ABOUT IT. THIS NEEDS FIXED OTHERWISE THERE MAY BE FATAL ACCIDENTS BY ENGINES BLOWING UP FROM THE OIL PSI GAUGE NOT WORKING PROPERLY AND SO ON. *TR

THE SPEEDOMETER ON MY 2004 CHEVY TRAILBLAZER EXT OPERATES INCORRECTLY. THE SPEED INDICATOR STICKS, GOES OVER 120 MILES AN HOUR AND STAYS THERE, AND SOMETIMES DOES NOT MOVE AT ALL. THIS IS AN EVERYDAY PROBLEM. *TR

1, NORMAL DRIVING BEFORE FAILURE. 2. THE SPEEDOMETER IS ENTIRELY INACCURATE EVEN IN PARK. 3. NOTHING HAS BEEN DONE OR CAN BE DONE TO FIX. *TR

1. NORMAL DRIVING. 2. THE RPM GAUGE WORKS ERRATICALLY AND IS NEVER ACCURATE. 3. WE COULD NOT FIND A REPLACEMENT PART AND IT HAS NOT BEEN FIXED. *TR

1. NORMAL DRIVING, 2. THE CD PLAYER WILL NOT EJECT THE CD, 3. ATTEMPTED TO GET IT OUT AND THEN RESEARCHED FOR HOW TO'S AND FOUND IT WAS IMPOSSIBLE TO FIX WITHOUT GETTING A NEW STEREO. *TR

1. FUEL TANK FAILURE, WITH GAS SMELL AFTER FILL UP. 2. SPEEDOMETER STOPPED WORKING 3. TEMPERATURE GAGE STOPPED WORKING

MY VEHICLE IS CURRENTLY AT 116,000 MILES AND THE SPEEDOMETER AND TACHOMETER ALL OF A SUDDEN WENT TO ZERO. IT CONTINUED TO STAY AT ZERO AFTER I TURNED THE VEHICLE OFF. THE NEXT TIME I DROVE IT, IT STAYED AT ZERO UNTIL HALFWAY THROUGH MY DRIVE WHEN NOW ITS STUCK AT 61 MPH, WHICH IS WHERE MY CRUISE CONTROL WAS SET. THE TACH NOW WORKS HALF THE TIME BUT THE SPEEDOMETER IS GIVING ME MISLEADING INFORMATION. I LIVE IN WISCONSIN WHERE THE WEATHER IS SUCH A VARIABLE. I AM ALWAYS USING MY SPEEDOMETER IN CERTAIN ROAD CONDITIONS. I HAVE CERTAIN SPEEDS I GO IN CERTAIN CONDITIONS (LIGHT SNOW, DEEPER SNOW, RAIN TO FREEZING RAIN, FREEZING RAIN, SLUSHY CONDITIONS, ICE, SLEET AND JUST PLAIN NORMAL.) CONSEQUENCES FOR NOT RETAINING THE CORRECT SPEEDS IN CERTAIN CONDITIONS IN WISCONSIN....GEE LET ME THINK....DEATH WOULD PROBABLY BE THE WORST. NOTHING'S BEEN DONE TO FIX THIS YET BECAUSE I CANNOT AFFORD IT. IT'S ONE OF THOSE THINGS THAT SHOULD JUST WORK AND ITS A [XXX] SHAME GM HASN'T DONE ANYTHING YET CONSIDERING ALL THE PROBLEMS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

INSTRUMENT CLUSTER PANEL ISSUE WITH TACHOMETER ACTUALLY EXCEEDING 7000RPM WHILE VEHICLE IS IDLING. I DID A QUICK SEARCH ONLINE AND FOUND THAT THERE HAVE BEEN MANY COMPLAINTS ABOUT THE CLUSTER PANEL MALFUNCTIONING. IT WAS RECOMMENDED THAT I FILE VIA NHTSA TO SEE WHAT MAY BE ABLE TO BE DONE OR IF THERE WAS ALREADY A FORMAL RECALL ON THIS PARTICULAR DEFECT. I HAVE TRIED REMOVING THE CLUSTER PANEL FUSE FROM THE FUSE BOX THEN STARTING VEHICLE THEN TURNING VEHICLE OFF AND REPLACING THE FUSE TO RECALIBRATE IT. MY UNDERSTANDING FROM THE RESEARCH IS THAT THE STEPPER MOTORS USED IN THE PANEL ARE FAULTY. *TR

ELECTRICAL - ALL GAUGES ARE NOT WORKING AND THE SPEEDOMETER QUITS WORKING WHILE DRIVING. *TR

MY SPEEDOMETER HAS STOPPED WORKING ON MY 2004 CHEVY TRAILBLAZER. HALF THE TIME IT SITS ON 0 THE OTHER HALF IT GOES 120MPH. I NEVER HAVE A CLUE HOW FAST I AM GOING. *TR

2004 CHEVY TRAILBLAZER SPEEDOMETER AND GAUGES STARTED WORKING ERRATICALLY AROUND SUMMER 2009. SPEEDO AND GAUGES STICK OR PEG OUT DAILY. GM DOES NOT RECOGNIZE THIS AS THEIR PROBLEM YET THERE ARE HUNDREDS, MAYBE THOUSANDS, OF BLOGS ON THE INTERNET OF THIS SAME PROBLEM. *TR

MY 2004 CHEVROLET TRAILBLAZER EXT HAS THE SAME PROBLEMS ALL THE OTHER TRAILBLAZERS HAVE. POOR DESIGN AND SUBPAR MANUFACTURING OF PARTS IN FOREIGN COUNTRIES HAVE RESULTED IN ELECTRICAL PROBLEMS THAT CANNOT BE FIXED.GAUGES AND LIGHTS RANDOMLY GOING CRAZY,HEAT AND A/C MAY OR MAY NOT OPERATE,VEHICLE MAY OR MAY NOT START,KEY MAY OR MAY NOT RELEASE FROM IGNITION. IGNITION SWITCH HAS BEEN REPLACED MULTIPLE TIMES IN LAST TWO YEARS AND OFTEN BRAND NEW IGNITIONS STRAIGHT OUT OF THE BOX FROM THE DEALER PARTS DEPARTMENT ARE NO GOOD. AS OTHER GM VEHICLES WITH THE SAME EXACT PROBLEMS HAVE BEEN RECALLED ONE WOULD THINK TRAILBLAZER OWNERS SHOULD DESERVE THE SAME COURTESY.CLEARLY GM DISAGREES. I GUESS WHEN YOU KNOW UNCLE SAM WILL ALWAYS BE THERE TO BAIL YOU OUT YOU CAN DO WHAT YOU WANT AND STILL SLEEP GOOD AT NIGHT. I WOULDNT KNOW . AS THE PARENT OF FOUR CHILDREN THIS IS A SERIOUS SAFETY ISSUE WITH ME. I CAN NO LONGER DRIVE IT AS I KNOW IT IS NOT DEPENDABLE.

ALL GAUGES FLUCTUATE CONSTANTLY OR STOP WORKING AT TIMES. YOU NEVER KNOW HOW FAST YOU ARE GOING OR IF THE CAR HAS APPROPRIATE FLUIDS. THIS IS A VERY DANGEROUS SITUATION AND I HAVE FOUND VIA THE INTERNET THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THIS ISSUE. THERE IS DEFINITELY SOME TYPE OF ELECTRICAL PROBLEM WITH THIS VEHICLE. *TR

TRANSMISSION SLIPPING BETWEEN 3RD AND 4TH GEAR. ENGINE REVS IN NEUTRAL, THEN TRANSMISSION WOULD RE-ENGAGE. FAILURE WOULD OCCUR EVERYTIME VEHICLE WAS DRIVEN. REPAIRED BY COMPLETE TRANSMISSION REBUILD. *TR

WE CURRENTLY OWN THREE CHEVROLET TRAILBLAZERS - 2004, 2005, 2006. ON EACH ON THE THREE TRAILBLAZERS, THE DASHBOARD INSTRUMENTS HAVE FAILED, INCLUDING THE SPEEDOMETER, OIL PRESSURE GAGE, FUEL GAGE, AND ENGINE RPM INSTRUMENT. THE DRIVER NO LONGER HAS THE ABILITY TO VERIFY HOW FAST THE VEHICLE IS TRAVELING, OR POTENTIAL PROBLEMS WITH THE ENGINE, OR THE REMAINING FUEL IN THE GAS TANK. IN TAKING THE VEHICLES TO THE DEALER, THEY INSIST THAT IT WILL BE A SIGNIFICANT REPAIR REQUIRING DIAGNOSIS AND REMOVAL OF THE ENTIRE DASHBOARD CLUSTER AND ESTIMATE THE COSTS TO BE WELL OVER $1500 FOR THE REPAIR. SINCE THE SAME PROBLEM HAS OCCURRED ON ALL THREE OF OUR CURRENTLY OWNED TRAILBLAZERS, THIS SUGGESTS A MANUFACTURERS DEFECT WITH THE ENTIRE DASHBOARD CLUSTER. *TR

ABOUT 10 MILES OUTSIDE OF DALLAS MY CHECK ENGINE LIGHT CAME ON BUT NO INITIAL PROBLEMS. LATER THAT NIGHT WHILE DRIVING ON THE INTERSTATE THE CAR WOULD NOT GO FASTER THAN 30MPH. I RETURNED HOME THAT NIGHT AND LEFT IT PARKED. THE NEXT DAY TOOK IT TO AUTOZONE AND THE GUY DID AN ENGINE CHECK STATING THAT MY TRANSMISSION HAS GONE OUT AND THAT IT WAS LOW ON FLUIDS. I ADDED 3 QUARTS OF TRANSMISSION FLUID WHICH SEEMED TO HELP A LITTLE BIT, BUT I DO NOT FEEL COMFORTABLE ENOUGH MAKING AN 8 HR TRIP BACK HOME. *TR

MY HEADLAMPS KEEP FLICKERING OFF. AT THIS TIME THEY DON'T COME BACK ON. FOR ABOUT 7 MONTHS THEY WOULD GO OFF AND I WOULD HAVE TO PULL OVER AND SHUT VEHICLE OFF. IT WOULD COME ON AFTER I LET IT SIT FOR A MINUTE. NOW THEY SHUT OFF AND WILL NOT COME BACK ON. *TR

2004 CHEVY TRAILBLAZER LT MODEL HAD DEFECTIVE SPEEDOMETER. CONSTANTLY SHOWING WRONG SPEED, AND STUCK BETWEEN 50 AND 120 MPH EVEN WHEN PARKED. *TR

SPEEDOMETER, TACHOMETER AND OIL PRESSURE GAUGE ALL STOPPED WORKING ON 2004 CHEVY TRAILBLAZER. *TR

MY CHECK ENGINE LIGHT STARTED COMING ON AND STAYING ON; THEN MY OIL GAUGE STARTED GOING WACKY, FROM ONE END TO THE OTHER; NEXT, MY GAS GAUGE WASN'T READING CORRECTLY AND I HAD TO KEEP PUTTING GAS IN THE CAR JUST TO MAKE SURE I DIDN'T RUN OUT BECAUSE YOU COULDN'T TRUST THE GAUGE. THE GAUGES OFTEN CORRECT THEMSELVES OUT OF THE BLUE AND THEN THEY START MESSING UP AGAIN WITH NO WARNING. TODAY, MY SPEEDOMETER READ 0 WHILE I WAS DRIVING ABOUT 40 MPH. IT STAYED AT 0 UNTIL I STOPPED AT A TRAFFIC LIGHT. WHEN I TOOK OFF, IT WENT UP TO ABOUT 45 WHEN I WAS ONLY GOING ABOUT 25-30. I HAVE NO IDEA HOW FAST I AM REALLY GOING, WHICH IS SCARY AND DANGEROUS. I AM ALSO VERY FRAZZLED BY ALL THE GAUGES READING DIFFERENT EVERY DAY WHEN I AM DRIVING 40 MILES BACK AND FORTH TO WORK WONDERING IF AND WHEN MY CAR IS GOING TO BREAK DOWN ON THE HIGHWAY OR IN HEAVY TRAFFIC. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER EXT. WHILE THE CONTACT WAS DRIVING AT VARIOUS SPEEDS, UNEXPECTEDLY THE SPEED ODOMETER AND OTHER GAUGES BECAME INOPERATIVE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING WHERE THEY STATED THAT THE FAILURE WAS CONTRIBUTED TO THE INSTRUMENT PANEL CLUSTER. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000.

LOW BEAMS WENT OFF AS I WAS DRIVING DOWN RURAL ROADWAY. THIS WAS AT 10:45 AT NIGHT ON MY WAY TO WORK. HAD TOO SIT BY SIDE OF ROAD FOR SOME TIME WITH NO LIGHTS. FINALLY CAME BACK ON. THIS HAS HAPPENED 4 OTHER TIMES SINCE THEN. I LIVE IN A RURAL AREA, WHEN THE LIGHTS GO OUT THERE ARE NO STREET LIGHTS AROUND TO ILLUMINATE THE ROADWAY. I HAVE HAD 2 NEAR CRASHES DUE TO THE DARKNESS OF THE AREA IN WHICH I WAS TRAVELING. THERE ARE NO CODES BEING THROWN WHEN THIS OCCURS, NO WARNINGS, THE LIGHTS JUST GO OUT. UNABLE TO LOCATE FAILURE POINT. HIGH BEAMS, TURN SIGNALS, PARKING LIGHTS WORK, JUST NOT LOW BEAMS. *TR

MY 2004 CHEVY TRAILBLAZER HAS MULTIPLE LIGHTS ON -BRAKES, AIRBAG,BATTERY, SERVICE ENGINE SOON. ALL THE GAUGES ON THE RIGHT-OIL, GAS, BATTERY ARE BELOW THE RED LINE AS IF THE CAR IS OFF. THE CAR LOCKED ITSELF WITH THE KEYS IN IT WHILE IT WAS TURNED OFF-HAD TO CALL EMERGENCY ROAD SERVICE TO UNLOCK. THE MECHANIC STATES ALL THE LIGHTS THAT ARE ON ARE ACTUALLY FUNCTIONING AND THAT THE DASHBOARD CLUSTER MODULE IS CAUSING THE PROBLEM. THIS IS A MAJOR SAFETY ISSUE AND IT APPEARS MULTIPLE PEOPLE HAVE HAD THE SAME TYPE PROBLEM WITH TRAILBLAZERS-WHY HASN'T THERE BEEN A RECALL RE: THIS ISSUE? *TR

CHECK ENGINE LIGHT - FOR OVER ONE YEAR NOW, AND 4 VARIOUS MECHANICS, NO ONCE CAN FIGURE OUT WHY MY CHECK ENGINE LIGHT COMES ON. I HAVE REPLACED TWO AIR SENSORS (ACTUALLY 3 - ONE WAS BAD)... I HAVE SPENT CLOSE TO $1,000 TO GET THIS FIXED - BUT THE DAM LIGHT CONTINUES TO GO ON (INTERMITTENTLY) SOMETIMES IT'S ON FOR A MONTH - OFF A DAY - ON TWO WEEKS - THERE IS NO PATTERN. THE LAST TIME THE LIGHT CAME ON, MY CAR BEGAN STALLING IN TRAFFIC AND STOP SIGNS. LAST MECHANIC SPENT 5 HOURS TRACING ALL THE CODES BACK - NOTHING. NEXT DAY HAD ANOTHER MECHANIC CHECK CODES AND THE ENGINE RUNNING COOL AS WELL AS A FEW OTHERS SHOWED UP. IF NO ONE CAN FIGURE THIS OUT - WHERE IS THE RECOURSE. I FEEL LIKE I AM BEING SCAMMED OVER AND OVER. I STALLED ON RT. 24 SLOWING DOWN IN TRAFFIC - AND WAS ALMOST HIT BY A BOX TRUCK BECAUSE I JUST SAT THERE. WHO CAN HELP DIRECT ME TO A REPAIR WHICH WILL ULTIMATELY END THIS ISSUE? NOW, THE LIGHTS OFF THIS WEEK (WATCH, NOW THAT I SAY THIS IT WILL COME BACK ON). THE ONLY THING I NOTICE IS THAT MANY TIMES THE LIGHT TURNED OFF AFTER I FILLED THE TANK. SO, IS THERE ANYONE OUT THERE WHO KNOWS WHAT'S WRONG (REFERRING TO MECHANICS WHO TAKE US FOR A RIDE $$$)? I CHALLENGE ANYONE OUT THERE TO FIGURE THIS OUT. *TR

I OWN A 2004 TRAILBLAZER EXT WITH THE I6 AND I'VE BEEN GETTING STRONG SMELLS OF EXHAUST FUMES INSIDE THE VEHICLE DO TO A FAULTY EXHAUST MANIFOLD THAT IS CRACKED. IT SEEMS THAT IT HAPPENS TO 90 PERCENT OF THE TRAILBLAZERS WITH THE I6 MOTOR. COME TO FIND OUT THAT THE EXHAUST MANIFOLD IS ON NATIONAL BACK ORDER WHICH TELLS ME THAT GM SHOULD DO SOMETHING ABOUT THIS SEEING THAT IT'S HARD TO DRIVE AROUND WITH THE WINDOWS UP AND THE HEAT ON. NOT ONLY IS IT A SAFETY HAZARD BUT IT'S ALSO AN EMISSION ISSUE. *TR

MY CHEVY TRAILBLAZER DISPLAYED A SERVICE ENGINE LIGHT AND 4 WHEEL DRIVE SERVICE LIGHT A FEW DAYS AGO. GOT IT TO THE DEALER. THEY STATED THE THERMOSTAT AND 4 WHEEL DRIVE SWITCH NEEDED REPLACED. ($550.00). THE DAY THIS WAS REPLACED, I DROVE IT HOME AND TESTED THE 4 WHEEL DRIVE SWITCH. AS SOON AS I PRESSED ON THE GAS IN 4 WHEEL DRIVE, THE TACH SHOT TO 5000. IT DISPLAYED 5000 FOR THE REST OF THE DAY (EVEN WHILE IDLING). THE NEXT DAY, THE TACH STOPPED WORKING ALL TOGETHER. DEALER WON'T TAKE RESPONSIBILITY FOR ANY ERROR OR REASONING TO WHY IT QUIT WORKING. JUST A COINCIDENCE????? *TR

FUEL PUMP FAILURE ON 2004 CHEVY TRAILBLAZER AT APPROX 36,000 MILES. *TR
