2005 CHEVROLET TRAILBLAZER EXT 370 Electrical System Problems

THE WHOLE INSTRUMENT CLUSTER DOES NOT WORK ANYMORE, DOES NOT LET ME KNOW HOW FAST I'M GOING OR HOW MUCH FUEL I HAVE, OIL PRESSURE GAUGE DOESN'T WORK, TEMPERATURE GAUGE DOESN'T WORK... WHY HASN'T THIS BEEN RECALLED? THIS IS VERY DANGEROUS, CONSIDERING I HAVE 4 KIDS THAT ARE CONSTANTLY IN THE CAR WITH ME AND I HAVE NO IDEA WHAT IS GOING ON WITH MY VEHICLE?? AND IT ALSO TELLS ME THAT MY FUEL LEVEL IS LOW, EVEN AFTER I FILL MY TANK. THIS SEEMS LIKE A VERY COMMON PROBLEM IN THESE VEHICLES, WHY HAS IT NOT BEEN CONSIDERED A SAFETY ISSUE????

I HAVE 2005 CHEVROLET TRAILBLAZER 4WD EXT LS 4.2 LITER. I NOTICED OVER PAST 3 YEARS THAT I BE AT DRIVE THROUGH FOR BURGERS AND ETC. THE CAR WOULD CUT OFF. I DID NOT THINK MUCH OF IT AT THE TIME. IT HAS GOTTEN CRITICALLY WORSE. IT WOULD CUT OFF IN MIDDLE OF THE HIGHWAY, DRIVE THROUGHS AND ETC. DURING THE PAST TWO YEARS I HAVE RE THE LUSTER AND OVER HEAD DOME LIGHT FLICKER. HEAD LIGHTS VERY DIM ON DRIVING ALSO I HAVE REPLACED ON THIS VEHICLE THE FUEL THROTTLE AND SENSOR, A CRANK SENSOR A CAM SENSOR, A TEMP SENSOR 4 POWER STEERING PUMPS NEW THE POWER STEERING RACK AND ASSEMBLY WHEEL HUBS AND BEARINGS, ALL NEW COILS SPARK PLUGS, BELT IDLE PULLEY POWER STEERING PULLEY CHANGE OIL EVERY 3,000 MILES AIR FILTER CHANGE BATTERY, UPDATED SOFT WARE, FLUSH FUEL SYSTEM, SERVICE THE AIR CONDITION REPLACED REAR SHOCKS,...

FOR THE 3RD TIME THE CLUSTER HAS GONE OUT. THIS RESULTS IN THE SPEEDOMETER, TEMPERATURE GAUGE AND OTHERS TO STOP WORKING. EACH TIME I AM EXPECTED TO TAKE MY VEHICLE TO A CHEVROLET MECHANIC FOR DIAGNOSIS AND PART REPLACEMENT AT $700.00+ EACH TIME. THIS MODEL HAS NO RECALL. I AM FED UP WITH PAYING THIS MUCH EVERY 3-4 YEARS FOR A DEFECTIVE PART. THERE HAS NEVER BEEN ANY SIGN BEFORE IT GOES OUT.

OUR 2005 CHEVY TRAILBLAZER SPEEDOMETER STOPPED WORKING. THIS HAS HAPPENED ON MANY OF THESE VEHICLES. IT IS A VERY EXPENSIVE FIX AND IT'S A DANGER TO DRIVERS NOT KNOWING HOW FAST THEY ARE TRAVELING.

THERE IS ALREADY A RECALL OUT FOR THE 2006 MODEL YEAR, BUT I KNOW THAT MINE IS PART OF IT. I HAVE A 2005 TRAILBLAZER AND THE HEADLIGHTS KEEP INTERMITTENTLY GOING OUT AS I AM DRIVING DOWN THE ROAD. THIS PROBLEM AS HAPPENED TO ME BEFORE IN THE PAST AND I WAS ABLE TO FINALLY REMEDY THE ISSUE BY REPLACING THE RELAY. THE PROBLEM HAS NOW RETURNED AND I HAVE EVEN BEEN PULLED OVER MULTIPLE TIMES FOR IT. AFTER DOING A QUICK GOOGLE SEARCH TODAY I DISCOVERED THAT THERE ARE TONS!!!!! OF PEOPLE WITH THE SAME ISSUE GOING BACK AS FAR AS 2002. HTTP://WWW.TOPIX.COM/FORUM/AUTOS/CHEVROLET-TRAILBLAZER/T32JTL93I9FKAUF4N HTTP://FORUMS.TRAILVOY.COM/SHOWTHREAD.PHP?T=47492 HTTP://CHEVROLETFORUM.COM/FORUM/TRAILBLAZER-27/2003-TRAILBLAZER-HEADLIGHTS-2588/ I ALSO RAN ACROSS THAT GM HAS ISSUED A RECALL FOR HEADLIGHTS, BUT IT ONLY COVERS YEARS 2006-2008. HTTP://FORTUNE.COM/2014/12/01/GM-RECALLS-316000-VEHICLES-BECAUSE-OF-MALFUNCTIONING-HEADLIGHTS/ CLEARLY!!!! THIS PROBLEM IS NOT LIMITED TO THOSE YEARS AND THERE ARE A LOT OF PEOPLE SUFFERING FROM THE SAME ISSUE OF NOT BEING ABLE...

ELECTRICAL ISSUES:VEHICLE DASHBOARD LIGHTS WILL SHOW DOOR GATE OPEN, DOOM LIGHTS WIL BE ON, RINGING BELL WHEN THE DOOR WOULD BE OPEN AND YET ITS ACTUALLY CLOSED, AS ALL CONTINUES TO GO AT ANY GIVEN TIME WHEN THE VEHICLE IS IN MOVEMENT. SPEED ODOMETER GAGE DOESN'T READ WHEN VEHICLE IS IN MOVEMENT AND THE GAS GAGE DOESN'T READ THE CORRECT LEVEL OF SHOWING HOW MUCH GAS IS IN VEHICLE. THIS IS A BIG SAFETY ISSUES CAUSE IT HAS ME WORRIED OF NOT KNOWING HOW MUCH GAS I HAVE BEFORE IT RUNS OUT OF GAS RISKING MYSELF AND OTHERS BECAUSE VEHICLE ALL OF A SUDDENNESS LOSES SPEED AND SHUTS DOWN.

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER EXT 370. THE CONTACT STATED THAT THE WHEN THERE WAS MOISTURE IN THE AIR, THE DRIVER SIDE MASTER SWITCH FAILED TO OPERATE WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 13V248000 (ELECTRICAL SYSTEM, VISIBILITY). THE FAILURE MILEAGE WAS 139,000.

MY SPEEDOMETER AND OIL GAUGE JUST QUIT WORKING FOR NO APPARENT REASON AND DOES NOT COME BACK ON UNTIL HOURS LATER.

SINCE OCTOBER 2014 THE SPEEDOMETER WOULD RANDOMLY START UP AT DIFFERENT INITIAL POINTS. SOME DAYS IT WOULD START AT 60 MPH, 10MPH AND RECENTLY IT STARTS UP AT 110MPH. WHEN THE VEHICLE IS IN MOTION THE NEEDLE WOULD MOVE WHEN ACCELERATING BUT THE READINGS ARE COMPLETELY INACCURATE. I HAVE READ VARIOUS ONLINE BLOGS OF THIS SAME INCIDENT HAPPENING TO NUMEROUS CHEVY TRAILBLAZERS IN GENERAL. GM DOES NOT HAVE THIS PROBLEM AS A RECALL THEREFORE I WOULD FORMALLY LIKE TO MAKE A COMPLAINT. THANK YOU FOR YOUR TIME. *TR

AT THIS TIME THE SPEEDOMETER STARTED MISREADING AND CONTINUES THROUGH TODAY. THEN THE FUEL GAUGE STOPPED READING AND AFTER THAT THE OIL PRESSURE GAUGE & AMP GAUGE STARTED MISREADING. I TALKED TO THE LOCAL CHEVROLET DEALERSHIP AND THEY TOLD ME I WOULD HAVE TO PAY FOR THE REPAIRS. *TR

THE DASH COMPONENT WENT OUT, LEAVING ALL OF THE GAUGES BROKEN, INCLUDING THE SPEEDOMETER AND GAS GAUGE. ALSO, THE FUEL SENSOR IS BROKEN SO IN ORDER TO HAVE A WORKING GAS GAUGE, BOTH THE DASH SYSTEM AND THE FUEL SENSOR MUST BE FIXED. THE DOORS LOCK AUTOMATICALLY AND SOMETIMES WON'T UNLOCK IF THEY WERE LOCKED WHEN THE CAR WAS TURNED OFF UNTIL THE CAR IS TURNED ON AGAIN. IT TAKES THEM 2 WEEKS TO FIX THE PROBLEM!! MEANWHILE, WE HAVE RUN OUT OF GAS, ALMOST CAUSING AN ACCIDENT, AND CONTINUALLY HAVE TO GAUGE OUR SPEED BY THE SPEED OF OTHERS AROUND US, IF WE ARE LUCKY TO BE TRAVELING WHERE THERE ARE OTHERS WHO HOPEFULLY ARE DOING THE SPEED LIMIT. IT'S GOING TO COST ABOUT $1500 TO FIX IT ALL AND HAVE A RENTAL CAR FOR THE 2 WEEK PERIOD IT TAKES THEM TO FIX IT. IT CAN'T BE FIXED...

MY 2005 TRAILBLAZER STARTED EXPERIENCING FALSE READINGS ON THE SPEEDOMETER AROUND 96,000 MILES. AT FIRST IT WAS OFF BY 5-10 MPH THEN IT WOULD CORRECT IT'S SELF. NEXT THE OIL PRESSURE GAUGE STARTED WITH FALSE READINGS BOTH HIGH, THEN LOW, NEITHER ACCURATE. NOW IT IS AT A POINT WHERE THE SPEEDOMETER IS NO LONGER READING ACCURATE SPEED AND IS NOT SHOWING ANY SIGNS OF EVER RE-CORRECTING IT'S SELF AND THE OIL PRESSURE GAUGE AS WELL AS THE TEMPERATURE GAUGE BOTH MALFUNCTION ON A DAILY BASIS IN ONE DIRECTION OR THE OTHER. IT APPEARS THAT THIS IS A KNOWN ISSUE WITH CHEVY TRUCKS IN THIS CLASS YET THE TRAILBLAZER IS THE ONLY MODEL IN THE CLASS TO NOT BE ADDRESSED WITH A RECALL. IF A PRODUCT IS FAULTY BY THE MANUFACTURERS STANDARD IT SHOULD BE ADDRESSED AND CORRECTED. *TR

LOWERED THE DRIVER'S POWER WINDOW & IT DIDN'T GO BACK UP. OPENED & CLOSED DOOR & TRIED BUTTON A FEW MORE TIMES, THEN IT WENT UP. UNSURE OF BURN SMELL AS I WAS ON HIGHWAY. CHECKED AGAIN WHILE STATIONARY & WINDOW BUTTON NON FUNCTIONAL. NOTED THAT INTERIOR DOME LIGHT DID NOT LIGHT WHEN DOOR OPENED & ALL POWER BUTTONS IN DRIVER'S DOOR (WINDOWS, LOCKS, MIRRORS) RENDERED NON-FUNCTIONAL. ALSO NOTED THAT THIS DOOR DOES NOT RESPOND TO REMOTE KEYFOB FOR LOCK/UNLOCK, AND DOOR BY-PASSES ALARM SYSTEM. ALARM CAN BE SET, DOOR OPENED WITH KEY AND ALARM WILL ONLY TRIGGER WHEN KEY IS PUT INTO IGNITION, BUT UNARMS WHEN IGNITION CRANKS. IT SHOULD ALSO BE NOTED THAT THE DRIVER'S DOOR IS THE ONLY DOOR THAT HAS A KEY LOCK MECHANISM. THE REST OF THE VEHICLE RELIES ON REMOTE OR DOOR SWITCHES. APPROXIMATELY ONE YEAR LATER I OPENED THE DOOR (AS I COULD...

BLOWERS (DEFROST/DEFOG ~ HEAT A/C) INTERMITTENTLY WORK. DIAL GOES FROM 1-5 AND TODAY IF EITHER BLOWER LEVEL #2 AND #5 IS SELECTED, BLOWER WILL CUT OFF. LAST MONTH IT WAS #1 AND SOMETIMES #5. *TR

THE CONTROLS IN THE FRONT DOORS FOR THE WINDOWS STOPPED WORKING. THERE WAS A SLIGHTLY BURNT SMELL WHEN I GOT IN THE CAR THAT DAY. NOW THERE IS A CLICKING SOUND IN MY DRIVERS DOOR THAT HAPPENS ABOUT EVERY 35-45 SECONDS EVEN WHEN THE VEHICLE IS TURNED OFF. WHEN THIS CLICKING SOUND OCCURS WHILE THE VEHICLE IS RUNNING MY ENGINE LOSES POWER. THIS IS ALSO KILLING MY BATTERY EVERY NIGHT BECAUSE IT IS OCCURRING EVEN WITH THE VEHICLE TURNED OFF WITH NO KEYS IN THE IGNITION. I AM AFRAID IT IS GOING TO START A FIRE IN MY DOOR. THERE IS ALREADY A RECALL FOR THE 2006 AND 2007 FOR THIS EXACT SAME ISSUE. 2005 NEEDS TO BE ADDED TO THE LIST BEFORE SOMEONE GETS HURT. *TR

WHILE DRIVING DOWN THE HIGHWAY, THE DOOR LOCKS BEGAN TO OPERATE INTERMITTENTLY, LOCKING AND UNLOCKING. THE DOOR LOCKS ALSO OPERATE WHILE PARKED IN THE GARAGE AND THE VEHICLE IS OFF. THERE IS A BUZZING SOUND IN THE DOOR AND THE LOCKS HAVE COMPLETELY DRAINED A RATHER NEW BATTERY. A NEW BATTERY WAS INSTALLED, BUT THE BUZZING AND THE INTERMITTENT OPERATION OF THE DOOR LOCKS CONTINUE. I WAS TOLD THERE WAS A RECALL ON SOME VEHICLES FOR THIS SAME PROBLEM, BUT GM TELLS ME THERE WAS NO RECALL ON THIS PARTICULAR VIN. DURING A CALL TO GM, I WAS TOLD THERE WAS A "RATHER LARGE RECALL" PENDING THAT WOULD BE FINALIZED THE MIDDLE OF JANUARY. I WAS ADVISED BECAUSE OF THE PROBLEM TO TAKE MY VEHICLE TO A DEALER TO HAVE IT REPAIRED AND GM WOULD REIMBURSE MY COST "IF IT WAS INVOLVED IN A RECALL". IN A SUBSEQUENT CALL TO...

SPEEDOMETER STOPPED WORKING STAYS POINTING AT 60 MPH AND WILL RISE FROM THERE AFTER STOPPING VEHICLE. *TR

UNCOMMENTED ACTUATION OF DOOR LOCKS, LOCK / UNLOCK SEVERAL TIMES, BRAKE SYSTEM FAILURE LIGHT ILLUMINATED, ABS LIGHT ILLUMINATED, CHECK ENGINE LIGHT ILLUMINATED, DRIVE GEAR INDICATOR SHOWN 1ST GEAR REGARDLESS OF GEAR SELECTED ON GEARSHIFT, ENGINE HAVING TROUBLE MAKING POWER, OPERATING VERY ROUGH. ALARM BELL ENUNCIATING FOR SHORT TIME. INTENTIONALLY SHUT CAR DOWN, RESTART NO CHANGE. FUEL GAUGE, OIL PRESSURE GAUGES, TEMP GAGE READ NORMALLY. *TR

HEATER, DEFROST DOES NOT WORK. BLOWER WILL NOT BLOW. ALL COMPONENTS HAVE BEEN REPLACED. *TR

FUEL GAUGE FAILURE. FUEL GAUGE STILL READS EMPTY AFTER TANK IS FULL. THE GAUGE WILL REGISTER HAVING FUEL SOME OF THE TIME, MOST OF THE TIME THE LOW FUEL INDICATOR WILL COME ON. I HAVE TO USE THE ODOMETER TO REMEMBER TO REFUEL. *TR

GAS GUAGE READS EMPTY EVEN THOUGH FULL TANK, BATTERY AND TEMP GAUGE ALSO GO UP AND DOWN, CHECK ENGINE LIGHT IS ON. I KNOW OF MORE THAN 8 PEOPLE WITH SIMILAR VEHICLES OF DIFFERENT MODEL YEARS WITH SAME ISSUE. CHEVY SENT A LETTER SAYING THAT THEY WOULD PAY 50% FOR THE REPAIR OF THE OF THE INSTRUMENT CLUSTER IF THE VEHICLE HAD LESS THAN 120,00 MILES OR WAS 10 YEARS OLD OR LESS. MY VEHICLE NOW HAS 146,000 MILES, BUT THE PROBLEM STARTED A YEAR AGO WHEN THERE WERE ONLY APPROX. 120,000 MILES ON IT. I FEEL THAT THIS IS A SAFETY ISSUE BEING THAT MY WIFE TRANSPORTS MY CHILDREN IN THIS VEHICLE AND SHOULD I NEGLECT TO TELL HER SHE NEEDS FUEL, SHE RUNS THE RISK OF BEING STRANDED SOMEWHERE WITH MY FAMILY, OR WORSE ON A HEAVILY TRAVELED ROAD WHERE THE VEHICLE COULD STALL WITH NO WARNING. THANK...

FUEL GAUGE QUIT WORKING. NOW THE OIL PRESSURE GAUGE WORKS ONLY SOME OF THE TIME. *TR

I OWN A 2005 TRAILBLAZER, THE FIRST PROBLEM HAD TO DO WITH THE GAS NOT PUMPING. IT WOULD CAUSE THE PUMP TO CUT OFF. THE PASSENGER SEAT'S PLASTIC SIDE BROKE OFF AND NOW THE DRIVER'S SEAT IS BROKE. THE DRIVER'S LUMBAR SELECTOR QUIT WORKING.THE SPEEDOMETER HAS STOPPED WORKING. I USE MY GPS.THEN THE FUEL GAUGE QUIT WORKING, THE "DUMMY LIGHT" STAYS ON ALL THE TIME. CD IS HUNG UP IN THE RADIO. THE FRONT FAN FOR AC/HEATING QUIT WORKING.THE OTHER FANS WORK AND THE AC COOLS.EVIDENTLY THERE ARE ALOT OF COMPLAINS WITH THIS CERTAIN MAKE/MODEL GM SHOULD FIX THE PROBLEMS. IF THEY DON'T FIX MY PROBLEMS MY NEST CAR WILL CERTAINLY NOT BE AN AMERICAN MADE ONE BECAUSE I HAVEN'T SEEN ALOT OF PRIDE WHEN WE HAVE TO BEG TO GET OUR CARS FIXED WHEN SHODDY PARTS ARE USED ON OUR CARS. *TR

THE DASH BOARD CLUSTER STOP WORKING SO THE AMOUNT OF GAS I PUT IN THE CAR DOES NOT SHOW HOW MUCH. THE SPEED OF THE CAR I CAN'T TELL HOW FAST I'M GOING. *KB

MY 2005 CHEVROLET TRAILBLAZER STARTED AT 60,000 MILES HAVING MY SPEEDOMETER GOING CRAZY AND IT FINALLY STUCK AT 120 AND ONLY MOVED OCCASIONALLY MOVED I TRIED TO GO WITH THE FLOW OF TRAFFIC, BUT ENDED UP GETTING A TICKET...THE FIRST IN MY 50 YEARS OF DRIVING. I WENT TO GET IT FIXED, BUT FOUND OUT EVEN THOUGH IT WAS A DEFECT IN THE ELECTRICAL HARNESS, CHEVROLET WAS ONLY FIXING IT IN CERTAIN OF THEIR EXPENSIVE MODELS. IT WAS GOING TO COST ME OVER $500, WHICH I CANNOT AFFORD. I USE MY GPS TO WATCH MY MILEAGE. NOW THE GAS GAUGE STOPPED WORKING, THE CD PLAYER, AND THE OTHER GAUGES ARE IN QUESTION...PLUS MY LIGHTS BLINK OFF AT NIGHT. I AM A SENIOR AND CANNOT AFFORD TO GET ANOTHER CAR, OR EVEN FIX THIS PROBLEM. I HAVE FOUND MANY COMPLAINTS ON THE TRAILBLAZER FOR THE SAME PROBLEM. CHEVROLET SHOULD HAVE TO...

I HAVE ENCOUNTERED A PROBLEM WITH THE SPEEDOMETER NOT WORKING PROPERLY OR NOT WORKING AT ALL IN SOME CASES, SOMETIMES GET STUCK AT A CERTAIN SPEED

2005 CHEVY TRAILBLAZER ACTUALLY MY PROBLEM STARTED ABOUT 2YRS AGO WHEN MY GAS GAUGE WENT OUT. THEN YEAR LATER I WAS SITTING IN TRAFFIC AND ONCE I GOT BACK UP TO SPEED MY SPEEDOMETER WENT OUT AND QUIT WORKIN. IT WOULD JUMP AROUND AND THEN SOMETIMES APPEAR TO BE READING CORRECTLY THEN JUMP TO ZERO OR WAY OVER PAST 90 WHICH OF COURSE I WAS NOT GOING THAT FAST. NOW MY OIL PRESSURE GAUGE AND TEMPERATURE GAUGE ARE GOING OUT AS WELL. AFTER CHECKING FOR RECALLS I SEE NOW THERE HAVE BEEN ALOT OF COMPLAINTS WITH THIS ISSUE IN THE SAME YEAR VEHICLE BUT NO RECALLS. IF THIS MANY VEHICLES ARE HAVING SIMILAR ISSUES WHY ISN'T CHEVY MAKING IT RIGHT? I KNOW MECHANICAL THINGS HAPPEN AFTER OWNING A VEHICLE BUT NOT THE SAME THING TO THIS MANY VEHICLES. *TR

PURCHASED THE 2005 TRAILBLAZER WITH 49,000 MILES. AT 50,000 MILES THE SPEEDOMETER STOPPED WORKING PROPERLY. WHEN I SLOWED DOWN FROM GOING 70 MILES PER HOUR, THE NEEDLE STAYED ON 70 AND WHEN I ACCELERATED IT WOULD ACT AS THOUGH 70 WAS THE NEW 0. NOW THE SPEEDOMETER POINTS DOWN PAST THE 120 MPH MARK AND WILL NOT BUDGE. GM TOLD ME THAT IT NOT UNDER WARRANTY AND IT WILL COST OVER $500 TO FIX. *TR

OUR 2005 CHEVY TRAILBLAZER HAS A NON WORKING FUEL GAUGE AND SPEEDOMETER. WE HAVE 4 CHILDREN. 2 OF WHICH LIVE OUT OF STATE AND WE DRIVE BACK AND FORTH SEVERAL TIMES A MONTH FROM SC TO TN TO PICK THEM UP. WHEN THE FUEL GAUGE WENT OUT WE WERE ANNOYED BUT WE JUST TOP THE GAS TANK OFF OFTEN, BUT THE SPEEDOMETER THAT JUST STARTED STICKING WE HAVE NO IDEA HOW TO HANDLE. WE DON'T HAVE THE MONEY TO GET IT FIXED BUT WE TRAVEL SO MUCH FOR SUCH LONG DISTANCES THAT IT IS EXTREMELY DANGEROUS. WHEN RESEARCHING ONLINE I SEE THAT THIS IS A VERY COMMON PROBLEM YET CHEVY HAS NOT ISSUED A RECALL. IF CHEVY DOES NOT ISSUE A RECALL FOR THESE WE WILL NOT EVER TRUST CHEVY PRODUCTS AGAIN. THE SAFETY OF AMERICAN FAMILIES OBVIOUSLY DOES NOT MATTER TO THEM. ONLY OUR BAIL OUT MONEY. *TR

SPEEDOMETER GOES HAYWIRE, FIRST 150MPH THEN 40 THEN 60 , IT GOES ALL OVER THE PLACE. I BELIEVE THIS IS A MAJOR SAFETY ISSUE. I'VE CHECKED INTO IT AND THOUSANDS OF PEOPLE ARE EXPERIENCING THE SAME ISSUES. THIS IS MY WIFE DAILY DRIVER AND SHE TRANSPORTS MY KIDS IN THIS VEHICLE. *TR

SPEEDOMETER NOT READING PRPER SPEED. STAYS AT O SOMETIMES, AND THEN YOU COULD BE GOING 25, AND IT READS 75. *TR

I HAVE HAD THE FOLLOWING PROBLEMS WITH MY 2005 CHEVY TRAILBLAZER EXT LS: 2008: FUEL SENSOR FAILURE, RUNNING BOARD FELL OFF 2009: HEAD AND TAIL LIGHTS GOING OUT FREQUENTLY, WINDOWS WOULD GET STUCK- COULD NOT GO UP OR DOWN- ALL DASH LIGHTS FLASHING, CAR STALLING OUT- NEEDED CIRCUIT BOARD REPLACED. ANTI-THEFT NON-FUNCTIONING. 2010:WINDSHIELD WIPERS WILL NOT SHUT OFF(REPLACED DISPLAY BOARD), IDLE PULLEY NEEDS TO BE REPLACED , 4X4 RUNNING ROUGH AND MAKING A SOUND,SPEEDOMETER NON-FUNCTIONING, RADIO STOPPED WORKING,GLOVE BOX LOCK BROKE, HEAT/AC STOPPED WORKING FIRST ON BLOWERS 4& 5 THEN STOPPED COMPLETELY I HAVE NOT BEEN ABLE TO AFFORD TO FIX ALL THESE REPAIRS, AS IT EXCEEDS $2,000. CAR IS OVER WARRANTY AND WAS BROUGHT USED FROM A FORMER GM DEALER AT UNDER 50K. I CONTACTED GM IN NOVEMBER 2010 AND THEY STATED THAT THEY MY VEHICLE WAS OUT OF WARRANTY AND THEY COULD NOT ASSIST ME. GM INITIATED CONTACT...

2005 CHEVROLET TRAILBLAZER INSTRUMENT (SPEEDOMETER) CLUSTER IS NOT WORKING. APPARENTLY THIS IS A COMMON DEFECT WITH THE TRAILBLAZER. IT SIMPLY STOPPED WORKING, AND NOW I AM TRYING TO SAVE THE MONEY TO REPLACE THE $500 CLUSTER & IN THE MEANTIME USE OTHER TRAFFIC TO GAUGE MY SPEED. THE FUEL GAUGE STOPPED WORKING AS WELL. *TR

2005 CHEVROLET TRAILBLAZER..THE SPEEDOMETER HAS WENT OUT ON MY TRUCK..IT IS READING 80 MPH SOMETIMES AND WHEN I TAKE OFF IT GOES WAY OVER 120 MPH.. THIS IS A SAFETY ISSUE AND I HAVE READY SEVERAL COMPLAINTS ON THIS YEAR AND MODEL TRUCK. I HAVE HAD THIS TRUCK FOR 5 YEARS AND I BOUGHT IT WHEN IT WAS NEW AND I'VE PUT SEVERAL THOUSANDS OF DOLLARS INTO THIS TRUCK THIS PAST 10 MONTHS AND NOW ITS GOING TO COST ME ANOTHER $500 DOLLARS TO GET THIS FIX. THERE SHOULD BE A RECALL ON THIS ISSUE FROM GM. I'M GOING TO COMPLAIN TO THE BBB. MY LATE HUSBAND WAS A GM EMPLOYEE AND HE WORKED FOR THEM FOR 15 YEARS AND WAS KILLED IN AN AUTO ACCIDENT LAST MARCH AND GM HAS JACKED ME AROUND SINCE THEN AND NOW I HAVE THIS ISSUE. I'M NOT GOING TO BUY ANOTHER GM VEHICLE...

AS YOU CAN SEE FROM BELOW THE COMPLAINT, SEEMS I GOT A CALL FROM NIKKI AT GM OR CHEVY AND THEY STATED I NEED TO BRING VEHICLE IN, PAY FOR THE DIAGNOSTIC AND THEN MAYBE THEY CAN DECIDE ON WHAT TO DO, I BELIEVE THIS ISSUE HAS GONE ON FOR 5 YEARS NOW AND THEY SHOULD BE CHECKING TO SEE WHAT THE ISSUE IS...COULD BE FAULTY WIRING, WHICH CAN LEAD TO A FIRE, SAFETY ISSUE, COULD BE A FALSE WARNING OR WORSE A REAL WARNING, AS YOU CAN SEE IN THE LINK I ENCLOSED TO THEM, MANY PEOPLE PAYING BIG DOLLARS TO NOT HAVE THIS ISSUE RESOLVED, HOW LONG DOES THIS GO ON, I AM HOPING YOU GUYS CAN STEP IN FOR US AND HOPEFULLY LIGHT A FIRE AND GET GM AND CHEVY TO FINALLY LOOK INTO THIS MATTER..THEY ARE GOOD ABOUT CRYING NO SALES AND NEED THE INFRACTION FROM...

LIGHTS DIMMING AND FLASHING ALTERNATOR NOT CHARGING, WIRING PROBLEM, DEALER HAS NO ANSWER. I HAVE VEHICLE JUST STARTED THIS AT 74000 MILES, WAS FINE UP UNTIL THAT POINT. HEATER FAN WORKS INTERMITTENTLY. GHOST ELECTRICAL PROBLEMS WITH DOOR LOCKS, RADIO , HIGH BEAMS. VERY SCARY TO DRIVE. *TR

MY 2005 CHEVY TRAILBLAZER IS COMPLETELY GOING CRAZY IT SEEMS EVERYTHING ELECTRICAL IS GOING WRONG WITH IT. I AM AFRAID TO LET MY WIFE OR MY KIDS DRIVE IN IT BECAUSE I NEVER KNOW WHAT'S GOING TO GO WRONG WHILE DRIVING. MY WHOLE GAS SYSTEM IS GONE FROM FUEL LEVEL INDICATOR TO THE GAUGE. MY ENTIRE DASHBOARD IS NOT WORKING. LIGHTS ARE GOING OUT. WHAT IS CRAZY ABOUT THIS IS THAT I AM ONE OF THOUSANDS THAT THIS IS HAPPENING TO. CHEVY NEEDS TO FIX THIS PROBLEM BEFORE SOMEONE DOES GET KILLED. WAITING FOR FATALITIES BEFORE MAKING CHEVY FIXES THERE AWFULLY MADE VEHICLES IS UNACCEPTABLE. I UNDERSTAND THE SITUATION OUR ECONOMY IS IN BUT THESE THOUSANDS OF TRAILBLAZER OWNERS THAT ARE HAVING THESE PROBLEMS SHOULDN'T BE PAYING THOUSANDS OF DOLLARS TO BE GETTING THERE ENTIRE ELECTRICAL PROBLEM FIXED. I DO NOT KNOW ONE OWNER OF A 2006 TRAILBLAZER THAT DOES...

2005 CHEVY TRAILBLAZER, CAR JUST DIES INTERMITTENTLY. I HAVE RESEARCHED THIS PROBLEM WITH CHEVYS AND WAS SURPRISED TO NOTICE THE THOUSANDS OF COMPLAINTS THAT ARE GOIN UNHEARD FROM GM AND THE FEDERAL GOVERNMENT. IM AFRAID THAT THIS WILL HAPPEN WHEN MY WIFE AND KIDS ARE DRIVING IN THE CAR. THIS SHOULD B INVESTIGATED IMM. *TR

I HAVE AN 05 CHEVROLET TRAILBLAZER EXT 4.2L WITH 90000 MILES AND LAST MARCH THE FUEL GAUGE QUIT WORKING BUT NOT BEFORE WE RAN OUT OF FUEL 2 TIMES NOT KNOWING THAT THE GAUGE WAS GIVING A FALSE READING.THE OCCURRENCE HAPPENED ON THE FREEWAY AND ONCE ON A BUSY STREET. VERY SCARY WHEN YOU HAVE THREE INNOCENT LITTLE GIRLS UNDER THE AGE OF 3 THAT RIDE IN THE VEHICLE. FROM DOING MY RESEARCH I SEE THIS A VERY COMMON PROBLEM AND A DANGEROUS ONE AT THAT BECAUSE WHEN THE TRUCK STOPS RUNNING YOU LOSE POWER STEERING AND POWER BREAKING. *TR

SPEEDOMETER QUIT WORKING ON MY 2005 CHEVY TRAILBLAZER AS I WAS ON THE HIGHWAY (I-75). AT FIRST IT WAS READING 20 TO 55 MILES PER HOUR FASTER THAN I WAS ACTUALLY GOING AND AN HOUR LATER IT QUIT ALL TOGETHER. AT THIS TIME IT DOES NOT SHOE A READING AT ALL. VERY HARD TO DETERMINE SPEED WITHOUT A SPEEDOMETER IN HEAVY TRAFFIC AND CREATES A HAZARD TO OTHER DRIVERS AND MYSELF. *TR

STARTED WITH THE SERVICE AIR BAG MESSAGE (KNOWN ISSUE). THEN THE FUEL GAUGE ACTED UP AND FINALLY WENT TO E AND STAYED. NOW HAVE AND OCCASIONAL SURGE IN THE FUEL WHEN I HAVE THE BRAKE PRESSED (KNOWN ISSUES). SPEEDOMETER STARTING ACTING UP AND NO LONGER WORKS (KNOWN ISSUE). OH AND THE CHECK ENGINE LIGHT IS NOW ALWAYS ON. STARTED INTERMITTENTLY (AGAIN, KNOWN ISSUE). WAS TOLD $500 FROM DEALER WHEN I CALLED TO REPORT THE SERVICE AIR BAG MESSAGE. RECALL SHOULD APPLY TO THIS VEHICLE, I DON'T KNOW WHAT THE VEHICLE WENT THROUGH BEFORE I PURCHASED IT. CLOTH SEATS/LEATHER SEATS, THE SERVICE AIR BAG "SENSOR" IS STILL BROKE! DON'T HAVE THE MONEY TO FIX ALL THE "KNOWN" PROBLEMS. *TR

THE SPEEDOMETER STOPPED WORKING ONE RANDOM HOT DAY. THERE WERE NO RESULTING INJURIES, INCIDENCES OR CRASHES AS A RESULT. MY TRAILBLAZER HAS YET TO HAVE A RELIABLE DAY WHERE MY SPEEDOMETER WORKS CONTINUOUSLY. *TR

I HAVE A 2005 CHEVROLET TRAILBLAZER LS EXT AND THE SPEEDOMETER, FUEL, AND BATTERY GAUGES DO NOT WORK PROPERLY. THERE IS A DIMMING OF THE LIGHTS WHILE DRIVING AND PEOPLE SOMETIMES THINK I AM FLASHING MY LIGHTS AT THEM. ACCORDING TO HTTP://FORUMS.TRAILVOY.COM/SHOWTHREAD.PHP?T=18419&HIGHLIGHT=GAS+GUAGE&PAGE=2 THIS HAS BEEN A KNOWN PROBLEM FOR SEVERAL YEARS AND NO ONE HAS DONE ANYTHING ABOUT IT. THERE ARE SEVERAL OTHER FORUMS OUT THERE THAT SAY THE SAME THING,THIS IS A MAJOR SAFETY HAZARD AND COULD CAUSE MAJOR PROBLEMS INCLUDING ACCIDENTS, SPEEDING TICKETS, RUNNING OUT OF GAS...THE PROBLEMS ARE ENDLESS I GUESS. SOMETHING NEEDS TO BE DONE. WHY HAS THERE NOT BEEN A RECALL ON THIS WITH SO MANY COMPLAINTS? ARE YOU WAITING FOR SOMETHING SERIOUS TO HAPPEN? *TR

SPEEDOMETER FAILS TO REGISTER PROPERLY SO YOU DON'T KNOW HOW FAST OR SLOW YOU ARE DRIVING; THIS COULD CAUSE SERIOUS INJURY WHEN DRIVING ON THE FREEWAY AND/OR UP/DOWN HILLS. WHEN IDLING, SPEEDOMETER WOULD SHOW FROM 60 TO 120 MPH; RESET OF SPEEDOMETER ONLY LASTED UNTIL NEXT ENGINE START. *TR

FUEL GAUGE FAILED. I RAN OUT OF GAS ON A VERY BUSY INTERSTATE WITH MY GRANDDAUGHTER IN THE CAR. THIS COULD HAVE BEEN A MAJOR ISSUE HAD I NOT BEEN ABLE TO GET OFF TO THE SIDE OF THE ROAD. IT SEEMS THIS IS A COMMON PROBLEM IN THE CHEVY TRAILBLAZER. I TOOK THE VEHICLE TO THE DEALER AND THEY DETERMINED IT WAS A FUEL SENSOR IN THE FUEL TANK. THE REPAIRS COST ME ALMOST $300. *TR

I OWN A 2005 CHEVY TRAILBLAZER AND THE SPEEDOMETER AND GAS GAUGE HAVE BOTH STOPPED WORKING. I STARTED HAVING PROBLEMS AUGUST 2009 WHEN I FILLED UP THE GAS TANK I LEFT THE GAS STATION AND IT SAID I WAS ON EMPTY. I TURNED BACK AROUND AND WENT BACK TO THE SAME GAS STATION AND THE MANAGER TRIED TO FILL IT UP AND IT SHOWED I HAD A FULL TANK AT THE PUMP. IT STARTED TO WORK AGAIN BUT THEN IT WOULD FLUCTUATE BACK AND FORTH. NOW IT'S JUST NOT WORKING AT ALL FOR ME. THE OTHER PROBLEM I HAVE IS THAT THE SPEEDOMETER WENT HAYWIRE. I WOULD SHOW I WOULD BE GOING 10 MPH AND ACTUALLY WAS GOING 50 MPH. THEN WHEN I WOULD STOP IT SHOWED WHILE IN PARK 70 MPH. I WOULD HAVE TO THEN TURN OFF AND ON MY CAR TO ZERO IT OUT. THE SPEEDOMETER IS...

SPEEDOMETER DOES NOT RECORD PROPER SPEED. *TR

SPEEDOMETER SHOWS INCORRECT READING. *TR

I HAVE A 2005 CHEVY TRAILBLAZER AND IT HAS MANY PROBLEMS. BUT THE MOST DANGEROUS, AT THIS POINT, IS THE SPEEDOMETER STOPS WORKING. SOMETIMES, IT WON'T GET OFF OF ZERO. OTHER TIMES, IT SHOWS THAT I AM GOING OVER 120 MPH, WHEN IN FACT, I AM GOING WITH FLOW OF TRAFFIC. AT OTHER TIMES, IT SHOWS EITHER 15 TO 20 MILES ABOVE OR BELOW THE SPEED I AM ACTUALLY DRIVING. THERE IS NO COMMON DENOMINATOR AS TO WHEN OR IF THE PROBLEM STARTS OR STOPS. IT IS VERY, VERY RANDOM. THE COST TO FIX WILL BE OVER $450.00. THERE ARE MANY OTHER TRAILBLAZER OWNERS THAT ARE HAVING THIS SAME PROBLEM. THE SPEEDOMETER PROBLEM COULD BE VERY, VERY DANGEROUS AS THE DRIVER DOES NOT KNOW HOW FAST, OR SLOW, THEY ARE ACTUALLY DRIVING. *TR

I OWN A 2005 CHEVY TRAILBLAZER IN DEC. 2009 I FILLED THE CAR WITH GAS AND THE FUEL GAUGE IMMEDIATELY REGISTERED EMPTY THE FUEL SENSOR HAS FAILED IT WILL COST $558.00 TO REPAIR. IN FEBRUARY THE SPEEDOMETER REGISTERED 120 MPH WHILE SITTING STILL FOR A STOP SIGN NOW THE SPEEDOMETER DOES NOT WORK. I CONTACTED GEN MOTORS IN DETROIT, MICHIGAN AND WAS ASKED TO HAVE DIAGNOSTIC DONE AT ED BOZART CHEVORLET. BY A REPRESENTATIVE IN CONSUMER COMPLAINTS THEY CONTACTED DISTRICT REPRESENTATIVE FOR CHEVY AND THEY BOTH SAID THAT THERE IS NOTHING THEY CAN DO TO HELP US. THE TOTAL COST TO FIX OUR CAR IS $1,258.00. WE WERE TOLD TO FIX THE CAR FOR SAFETY REASONS AND IF THEY DECIDED TO RECALL THE TRAILBLAZER WE MIGHT BE REIMBURSED. THERE ARE SEVERAL COMPLAINTS IN THE COMPUTER CONCERNING THE SAME PROBLEMS WITH THIS CAR. *TR
