2003 CHEVROLET TRAILBLAZER Electrical System Problems

WE OWN A 2003 CHEVY TRAILBLAZER AND THE GAUGES CONSTANTLY MESS UP. SOME MY SPEED, OIL GAUGE AND RPM SEEM TO ACT NORMAL, THEN ALL OF A SUDDEN THE GAUGES START MISREADING OR THE SPEEDOMETER WILL GO DOWN TO ZERO. THIS IS A MAJOR SAFETY ISSUE. I CAN'T TELL HOW FAST I'M GOING AND I DON'T UNDERSTAND WHY THERE IS NO RECALL ON THIS PROBLEM. I HAVE READ NUMEROUS POST WITH PEOPLE HAVING THE SAME ISSUES. ITS NOT SAFE FOR ANYBODY NOT TO KNOW HOW FAST THEIR GOING. GM NEEDS TO INITIATE A RECALL AND COVER THE COST FOR THIS PROBLEM. WHAT HAS TO HAPPEN TO SOMEONE FOR A RECALL TO TAKE PLACE, WHY NOT BE SMART AND PREVENT A SAFETY HAZARD BEFORE SOMEONE IS HURT. THIS IS A MANUFACTURER FAULT, NOT AN OPERATOR FAULT. NUMEROUS DEALERSHIPS HAVE TOLD US THIS IS A MANUFACTURER FAULT. *TR

2003 TRAILBLAZER LTZ. I'VE BEEN HAVING PROBLEMS WITH THE GAUGES ON THE DASHBOARD. OIL GAUGE WENT OUT ABOUT A YEAR AGO, THEN THE FUEL GAUGE WENT OUT ABOUT 6 MONTHS AGO, AND NOW THE RPM JUST WENT OUT A FEW WEEKS AGO. ARE THERE A RECALL TO FIX THE ELECTRICAL PROBLEM ON THE DASHBOARD? I WAS ABLE TO LOOK AT THE ODOMETER AND SEE HOW MANY MILES I HAVE LEFT UNTIL I NEED TO FILL UP. *TR

THIS IS A THIRD TIME THE ABS WARNING LIGHT HAS COME ON MALFUNCTIONING SAYING WE NEED SERVICE ONCE IN MONTANA AND THEN ANOTHER INCIDENT IN 2008. "SERVICE BRAKES, AIR ANTILOCK ABS WARNING LIGHTS COME ON IN THE DRIVERS INFORMATION CENTER. HOWEVER, IT HAPPENS EVERY TIME IT GETS 5 TO 10 DEGREES OR MORE BELOW ZERO. THE FIRST TIME I TOOK IT INTO GARAGE AND THEY CLEANED UP THE ABS GROUND CONNECTION ON THE FRAME. THIS IS A SAFETY ISSUE BECAUSE A PERSON DOESN'T KNOW IF IT IS ACCURATE OR ANOTHER FALSE ALERT. I WOULD HOPE THAT OTHER PERSONS REPORT THESE ISSUES, AND THAT THE MANUFACTURERS WOULD BE FORCED TO REPAIR THE ISSUE. *TR

WHEN DRIVING MY VEHICLE THAT SPEEDOMETER ON THE RPM DOES NOT WORK, AND NOW I WAS TOLD THAT THE COMPUTER WAS MESSED UP. I HAVE REPLACED THE BATTERY, AND THEN THE FUSE UNDER THE SEAT GETS REALLY HOT, AND SOMETHING NEEDS TO BE DONE ABOUT IT. I HAVE EVEN GOT A TICKET FOR SPEEDING AND MY SPEED O METER WAS SET AT 65 AND I WAS TOLD BY THE HIGHWAY PATROL THAT I WAS GOING 75. *TR

THE SPEEDOMETER WORKED GREAT FOR ABOUT 20 MINUTES THEN IT JUST SLOWLY STOPPED WORKING. SOMETIMES IT COMES ON SOMETIMES IT DOESN'T, I HAVE NO IDEA HOW FAST I'M DRIVING. *TR

VEHICLE: 2003 CHEVY TRAILBLAZER EXT LT V6 REAR WHEEL DRIVE ISSUE: SPEEDOMETER AND TACHOMETER FAILED. DRIVER UNABLE TO DETERMINE SPEED AT ANY TIME WHILE DRIVING. NEEDLES FOR CONSOLE CLUSTER STUCK IN POSITION AND DO NOT CHANGE WHILE ACCELERATING OR DE-ACCELERATING. *TR

THE PROBLEM THAT I HAVE WITH MY TRUCK IS AN ELECTRIC PROBLEM INVOLVING THE LIGHT RELAYS, WHICH I AD TO REPLACE SEVERAL TIMES DUE TO THEM BEING DAMAGED, LEAVING ME WITHOUT LIGHTS. MY MAIN CONCERN IS THAT I DRIVE AT NIGHT OFTEN AND I AM IN DANGER WHEN I HAVE THE LIGHTS ON AND OFF. I DID RESEARCH ON SEVERAL FORUMS WHERE SAME-VEHICLE-OWNERS HAVE EXPERIENCED THE SAME ISSUES. *TR

BOUGHT USED FROM A DEALER. HAD FOR 2 DAYS WHEN HAD FIRST PROB THAT WAS FIXED GOT BACK AFTER A WEEK. RAN GREAT. DROVE FOR 1 DAY AND RAN GOOD, STOPPED AT A STOP SIGN AND WENT TO PULL ONTO MAIN HIGHWAY AND WOULDN'T MOVE FORWARD. BACKED UP FINE BUT NO FORWARD. I FINALLY GOT IT TO CRAWL FORWARD. AFTER A LIL WHILE IT KICKED BACK IN AND RAN FINE TIL I STOPPED AGAIN. FINALLY I MADE IT HOME AND PARKED IT. AFTER THEY FINALLY CAME AND TOWED IT AND "FIXED" IT I HAD IT AND DROVE IT FOR 1 DAY AND HAD SAME PROBLEM. AFTER IT SAT FOR A WHILE IT DID GO AGAIN. PULLED INTO DRIVEWAY AND PARKED IT. STILL WAITING FOR IT TO BE TOWED AND "FIXED" AGAIN AND HOPEFULLY RIGHT THIS TIME. I HAVE RESEARCHED THIS PROBLEM AND FOUND IT HAPPENS A LOT. SOUNDS LIKE IT...

THIS IS JUST THE MOST RECENT OF ELECTRICAL PROBLEMS I HAVE HAD WITH THE 2003 TRAILBLAZER LT. SINCE THE VEHICLE REACHED ABOUT 47000 MILES I HAVE HAD REPETITIVE ELECTRICAL PROBLEM: AC WENT OUT, RADIO WENT OUT, REPLACE ALTERNATORS THREE TIMES BATTERIES 4, REFUSAL TO START, SOME POWER VAMPIRE SUCKING OUT THE POWER, AND NOW I AM DRIVING ALONG AND THE ENTIRE INSTRUMENT CLUSTER STOPS WORKING. I GET TO THE GROCERY STORE AND SHOP THEN COME OUT AND IT IS WORKING AGAIN. THEN THE NEXT DAY, NONE OF THE GAUGES ARE WORKING FROM THE TIME I STARTED IT. I CALLED CHEVY AT 1-800-222-1020 AND WAS INFORMED THERE IS NO RECALL, BUT I SEE THIS IS A COMMON PROBLEM ACCORDING TO ON-LINE COMPLAINTS. [XXX], AT CHEVROLET SAID THEY CAN'T DO ANYTHING UNTIL IT IS SEEN BY A DEALER. I HAVE EVALUATION APPOINTMENT SET FOR 3/4/2013. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF...

AFTER PUTTING THE DRIVERS WINDOW DOWN AT A FAST FOOD DRIVE THRU IT WOULD NOT GO BACK UP. THIS WAS IN JANUARY, VERY COLD IN MICHIGAN. DEALER SAID MOISTURE MUST HAVE GOTTEN INTO SWITCH AND THE WHOLE MODULE HAD TO BE REPLACED. I ASKED IF THAT MEANS THE DOORS CAN'T BE OPENED WHEN IT WAS RAINING, HE SAID YES THEY CAN BUT FOR SOME REASON GM HAS A LOT OF DRIVERS DOOR WINDOW SWITCHES GOING BAD ON THE TRAILBLAZERS. THE COST TO HAVE IT REPLACED WAS $430 WHICH WE PAID SEEING HOW ONLY THE DEALER CAN PROGRAM THE NEW SWITCH. IT'S NOW ONE YEAR LATER AND THE SAME SWITCH HAS GONE BAD AGAIN, I CALLED THE DEALER BUT WERE OVER THE 12,000 MILE WARRANTY. IT WILL COST ANOTHER $430 TO REPLACE AGAIN. *TR

TACHOMETER QUIT WORKING FIRST, THEN SPEEDOMETER. THIS IS AN OBVIOUS SAFETY CONCERN. DEALERSHIP PREVIOUSLY INDICATED IT WILL COST ABOUT $1,000 TO FIX. THERE ARE A LOT OF COMPLAINTS BUT THERE IS NO BULLETIN OR RECALL ON THIS SO GM REFUSES TO DO ANYTHING. A SPEEDOMETER SHOULD NO GO OUT ON A CAR, NO MATTER HOW MANY MILES AND IF IT IS NOT AN ISOLATED INSTANCE, THERE NEEDS TO BE A RECALL. WHY IS THERE A RECALL ON OTHER GM MODELS BUT NOT THE TRAILBLAZER? *TR

THE GAUGE CLUSTER ON MY 2003 CHEVY TRAILBLAZER STOPPED WORKING OVER TWO YEARS AGO. FROM THE READOUT UPON MY DASHBOARD GAUGES, I HAVE NO IDEA AT WHAT SPEED I'M DRIVING, HOW MUCH FUEL IS IN MY TANK, WHAT IS THE ELECTRICAL SUPPLY FROM MY BATTERY, OR THE ENGINE'S OIL PRESSURE. THE TACHOMETER DOES NOT REGISTER PRM'S. THANKFULLY I USE A TOMTOM GPS TO GAUGE MY SPEED, AND THE ODOMETER DOES FUNCTION, SO I KNOW TO STOP FOR A FUEL REFILL EVERY 250-300 MILES TRAVELED. THIS WILL USUALLY PLACE ME AT BETWEEN 1/4 TANK AND EMPTY. *TR *JS

CPSC#I11A0455A. 2003, 2005 CHEVROLET TRAILBLAZER. CONSUMER STATED HE HAS ELECTRICAL PROBLEMS WITH BURNED CONNECTIONS AT HEADLIGHTS AND BLOWER MOTOR RESISTORS. *LN THE CONSUMER STATED ONE OF THE 2003 CHEVROLET TRAILBLAZERS HEAD LIGHT CONNECTORS BURNED, THE OTHER 2003 AND 2005, THE CONNECTOR FOR THE AC BLOWER RESISTOR BURNED. *JB

SPEEDOMETER DOES NOT GIVE TRUE SPEED SOMETIMES AND SOMETIMES IT WILL BE RIGHT, SOMETIMES SPEEDOMETER WILL BE AT 50 MPH WHEN THE VEHICLE IS NOT MOVING. TURNING. SWITCH OFF AND ON. SPEEDOMETER NEEDLE WILL GO BACK TO ZERO. TECHOMETER DOSE NOT WORK SOMETIMES. HAVE CHEKED ON LINE COMPLAINTS ABOUT THIS PROBLEM THERE ARE ALOT OF COMPLAINTS WITH THE SAME PROBLEM. THERE SHOULD BE A RECALL ON ALL THESE VEHICLES. *TR

WAS PREVIOUSLY CONTACTED BY AN "[XXX]" FROM WASHINGTON, DC TO RETRIEVE THE POWER WINDOW MODULE THAT HAD CAUGHT FIRE. I WAS GOING TO TURN THE PART OVER TO NHTSA. I AM IN DC AT THE US POSTAL SERVICE HQ ON MON/WED/TH. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I HAD GONE TO A FRIENDS HOUSE WITH MY BOYFRIEND AND OUR 10MONTH OLD DAUGHTER THE CAR WAS WORKING GREAT ON 12-31-11 AT AROUND 5PM WE PARKED THE VEHICLE. ON OUR WAY HOME AT ABOUT 10:45PM WE GOT ON THE ROAD CAR DROVE FINE WE JUMPED ON THE FWY IT WAS FOGGY AND REALLY HARD TO SEE WE WERE ON THE 54 FWY IN SAN DIEGO APPROACHING THE 805 SOUTH THERE IS A HIGH ON RAMP WE WERE GOING ABOUT 55 TO 60 AND ALL OF A SUDDEN I PUSHED ON GAS AND LOST ALL POWER TO VEHICLE IT SOUNDED LIKE I WAS IN NEUTRAL AND BECAUSE IT WAS UP HILL AND CURVED VERY DIFFICULT TO SEE US WITH JUST HAZARD LIGHTS ON. I WAS PRAYING THINKING SOMEONE WAS GOING TO TAKE US OUT. EVERY CAR WOULD SWERVING AROUND US AND HONKING WE FINALLY PULLED OVER TO THE SIDE OF...

I AM THE ORIGINAL OWNER OF A 2003 CHEVY TRAILBLAZER. WHEN I FIRST PURCHASED THE VEHICLE IN THE MONTH OF OCTOBER/2002, I DIDN'T EXPERIENCE ANY PROBLEMS UNTIL MAYBE THE FOURTH YEAR, GOING ON ITS 5TH; RIGHT BEFORE THE WARRANTY WAS ABOUT TO EXPIRE. THE FIRST PROBLEM I ENCOUNTERED WITH THE VEHICLE WAS THE TRANSMISSION. IT DIDN'T WANT TO CHANGE GEARS PROPERLY. BECAUSE OF THE 5 YEAR WARRANTY, THE DEALERSHIP WAS ABLE TO FIX THAT PROBLEM, AT THAT TIME. TODAY, I CONTINUE TO EXPERIENCE TRANSMISSION PROBLEMS: WITH A LOUD NOISE, A STRUGGLE IN HORSE POWER AND A VIBRATION WHEN I AM AT A COMPLETE STOP. I HAVE SPENT SO MUCH MONEY ON OTHER ELECTRICAL PARTS AS WELL. I HAVE PURCHASED OVER TEN LIGHT BULBS FOR REAR BRAKE LIGHTS THAT CONTINUE TO MALFUNCTION. I RECENTLY REPLACED A RELAY BECAUSE THE HEAD LIGHTS WOULD CONSTANTLY GO OUT AFTER THE VEHICLE WAS TURNED ON....

I HAVE BOUGHT MANY CHEVY VEHICLES BUT WITH ALL THE PROBLEMS IM HAVING WITH THIS TRUCK IM NOT SURE I WILL PURCHASE ANOTHER. LAST YEAR MY TRANSMISSION WAS GIVING ME PROBLEMS AND THERE WAS A RECALL ON IT AND MY TRUCK WAS NOT COVERED UNDER THE RECALL ALSO SAME WAS WITH THE TAIL LIGHTS. THIS YEAR I AM HAVING PROBLEMS WITH MY WIPERS DURING RAIN STORM I WENT TO TURN THEM ON AND NOTHING. I COULDNT SEE SO I HAD TO PULL OVER UNTIL THE RAIN HAD LET UP(2HRS LATER). I AM JUST SPEECHLESS WHEN IT COMES TO THESE "RECALLS". IT SEEMS THAT MYSELF NOR ANYONE I KNOW EVER FALLS ON THESE LISTS, YOU WOULD THINK WITH ALL THE MONEY WE ARE PAYING TO PURCHASE THESE VEHICLES THAT SOMEONE WOULD WANT TO MAKE SURE THEY KEEEP OUR BUSINESS. *TR

PANEL CLUSTER FAILED WITH RED BLARING EMERGENCY LIGHT STAYS ON AND CAUSES VEHICLE LIGHTS TO STAY ON. ALSO CAUSES VEHICLE NOT TO SHIFT PROPERLY. ALL DASHBOARD COMPONENT INDICATOR FAILS WHICH HAZARDOUS TO SAFETY OF INDIVIDUAL. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE ENTIRE INSTRUMENT PANEL WAS INOPERABLE AND HE WAS UNABLE TO DETERMINE HOW FAST OR SLOW HE WAS TRAVELING OR HOW MANY MILES WERE ON THE VEHICLE. THE DEALER DID NOT OFFER ANY ASSISTANCE SINCE THERE WAS NO RECALL. THE MANUFACTURER HAD NOT BEEN NOTIFIED NOR WAS THE VEHICLE DIAGNOSED OR REPAIRED. THE CURRENT MILEAGE WAS 122,000. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

AFTER EXITING A FREEWAY AT 70 MPH, CAME UP ON A REDLIGHT AND 45 MPH ZONE. STOPPED AT THE REDLIGHT AND THE NOTICED THE SPEEDOMETER WAS STILL REGISTERING 70 MPH. THE GAUGE MOVES BUT WON'T SET TO 0 MPH WHEN STOPPED. REMAINS AT OR AROUND 70 MPH WHEN PARKED OR STOPPED. *TR

SPEEDOMETER STOPPED WORKING. AFTER VEHICLE WAS TURNED OFF IT STARTED WORKING AGAIN. RESEARCHED INTERNET AND I FOUND THE THIS IS A KNOWN PROBLEM WITH THIS VEHICLE. AFTER TALKING TO SOMEONE ABOUT IT AND THEY HAVE A 2003 TAHOE THEY HAVE THE SAME PROBLEM. IF CHEVORLET IS AWARE OF THIS PROBLEM SOMETHING SHOULD BE DONE ABOUT IT. WE SPEND ALOT OF MONEY ON VEHICLES AND THIS SHOULD NOT HAPPEN. I DON'T FEEL THIS IS A WEAR AND TEAR ISSUE. *KB

THE SPEEDOMETER IN MY 2003 TRAILBLAZER RARELY READS CORRECTLY. I AM NOT ABLE TO TELL HOW FAST OR SLOW I AM GOING. THIS IS THE ONLY GAUGE THAT IS NOT FUNCTIONING PROPERLY, THE OTHER GAUGES WORK FINE. I FEEL THIS IS A SAFELY ISSUE AND SHOULD SOMEHOW BE COVERED BY A RECALL BECAUSE SO MANY PEOPLE HAVE ISSUES STATED ACROSS THE INTERNET WITH THIS SAME PROBLEM. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE INSTRUMENT CLUSTER WAS DEFECTIVE, CAUSING ALL THE GAUGES TO READ INACCURATELY. THE DEALER DIAGNOSED THAT THE VEHICLE WOULD NEED A NEW INSTRUMENT CLUSTER. THE MANUFACTURER WAS NOT CONTACTED AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 70,000 AND THE CURRENT MILEAGE WAS 113,000.

MY 2003 CHEVY TRAILBLAZER DOES NOT START. THERE IS NO SPECIFIC TIME, PLACE, OR EVENT THAT LEADS TO THE VEHICLE NOT STARTING EVERY COUPLE OF WEEKS THE VEHICLE JUST DOESN'T START. I WILL LET THE TRUCK SIT FOR AN HOUR OR SO THEN ATTEMPT TO START IT, THEN IT DOES START. I HAVE TAKEN IT TO THE DEALER AND THEY COULDN'T DUPLICATE THE ISSUE I WAS HAVING. I DID SOME RESEARCH ONLINE AND OTHERS HAVE SUGGESTED IT COULD BE THE BATTERY, TEMPERATURE SENSOR, IGNITION SWITCH, OR STARTER. I HAVE REPLACED ALL BUT THE STARTER BUT THE PROBLEM PERSISTS. I HAVE BEEN TOLD THAT THE STARTER IS GOOD SO I AM AT A LOSS AS TO WHY THE PROBLEM KEEPS OCCURRING. *TR

WHEN STARTING THE VEHICLE, IT PERIODICALLY WILL NOT START, LOSE ALL POWER, KEY GETS STUCK IN THE IGNITION WITHOUT ABILITY TO RETURN IGNITION TO OFF POSITION. THERE IS A SOUND (LIKE A HIGH VOLTAGE SOUND COMING FROM A TRANSFORMER) AND EVENTUALLY RESETS ITSELF, UNTIL 2 DAYS AGO. IT WOULD NOT RESET ITSELF, RESULTING IN IT BEING TOWED TO A REPAIR CENTER. THEY INDICATED IT WAS THE ALTERNATOR AND BATTERY AND AFTER CHANGING BOTH, THE SERVICE ENGINE SOON LIGHT CAME BACK ON AND THE HIGH VOLTAGE SOUND HAS RETURNED. THERE ARE TIMES THE REAR WIPER WILL TURN ON WITHOUT MY TOUCHING ANYTHING AND TIMES WHERE THE RPM GAGE WILL GET STUCK.

FRONT HEADLIGHTS WILL NOT WORK, AND ARE WIRES ARE BURNT, AIR AND HEATER WILL ONLY BLOW ON THE FLOOR SETTING EVEN IF PUT ON A DIFFERENT SETTING, WHEN YOU TURN AC ON THE BACK WINDSHIELD WIPER COMES ON. WHEN STARTING THE CAR THERE IS A LOUD CLICKING THAT SOUNDS LIKE IT IS COMING FROM THE DASH. IF STOPPED JUST FOR A FEW SECONDS WHILE AT A STOP LIGHT OR STOP SIGN THE TEMP WILL GO FROM NORMAL TO 260! AS LONG AS YOU ARE GOING AT LEAST FAST ENOUGH TO PUSH AIR THROUGH THE GRILL IT WON'T RUN HOT, BUT IF YOU ARE IN TOWN AND TRAFFIC IT WILL RUN HOT AND WILL NOT COOL OFF UNLESS YOU EITHER STOP AND LET IT COOL OFF OR GET TO WHERE YOU CAN GO FAST ENOUGH TO PUSH THE AIR! THE CAR WILL LOCK WHILE IT IS RUNNING AND IN PARK. IT...

SPEEDOMETER QUIT WORKING. THIS IS A COMMON PROBLEM WITH THIS VEHICLE AND SHOULD BE COVERED UNDER A FACTORY RECALL. *TR

I OWN A 2003 CHEVROLET TRAILBLAZER. MY CLUSTER STARTED TO MALFUNCTION IN NOVEMBER 2010. I PURCHASED THE VEHICLE IN JULY 2010. THE ODOMETER DOESN'T WORK AT ALL, AND THE SPEEDOMETER SPINS AND SPINS AROUND, WHICH DOESN'T REGISTER THE CORRECT SPEEDS. WHILE SEARCHING THE INTERNET AND THIS SITE, THIS IS A COMMON PROBLEM THAT HAPPENS WITH THESE VEHICLES THAT CHEVROLET IS NOT FIXING. THIS SHOULD BE RECALLED SO THAT CHEVROLET CAN PROPERLY FIX THIS PROBLEM. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT ALL OF THE INSTRUMENT PANEL GAUGES EXCLUDING THE FUEL LEVEL GAUGE WAS READING INACCURATELY. WHEN DRIVING AT ANY SPEED, THE SPEEDOMETER REMAINED AT THE SAME SPEED REGARDLESS OF HOW FAST OR SLOW HE WAS DRIVING. BOTH THE DEALER AND MANUFACTURER WERE INFORMED OF THE FAILURE AND ADVISED HER THAT THERE WERE NO RECALLS. THE VEHICLE WAS NOT REPAIRED. THE CURRENT MILEAGE WAS APPROXIMATELY 120,000 AND THE FAILURE MILEAGE WAS 80,000.

TL*THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THE FUEL GAUGE WAS DEFECTIVE AS IT GAVE INACCURATE READINGS. THE DEALER WAS CONTACTED WHO STATED THE FAILURE WAS NOT A SAFETY ISSUE. THE MANUFACTURER WAS CONTACTED WHO DID NOT OFFER ANY ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 72,000 AND CURRENT MILEAGE WAS 74,000.

SAFETY ISSUE!!!! I OWN A 2003 CHEVY TRAILBLAZER. MY SPEEDOMETER STARTED ACTING UP A COUPLE OF MONTHS AGO AND GOT WORSE THIS MONTH. SOMETIMES THE NEEDLE STARTS AT 50 OR 70 MPH INSTEAD OF 0 AND MOVES UP FROM THERE. IT WILL SAY THAT I AM DOING OVER 120 MPH WHEN I AM ONLY GOING ABOUT 45. OTHER TIMES IT WILL STAY ON ONE NUMBER AT NOT MOVE AT ALL. TWO WEEKS AGO I TURNED ON MY CAR AND THE NEEDLE WAS POINTING STRAIGHT DOWN TO THE ODOMETER. I BOUGHT A NEW BATTERY AND THAT DID NOT HELP. WE UNPLUGGED THE BATTERY FOR 30 MIN AND IT REST EVERYTHING. TWO DAYS LATER I WAS HAVING PROBLEMS AGAIN. WE RESEARCHED THE PROBLEM ON LINE ONLY TO FIND OUT THAT A VERY LARGE NUMBER OF TRAILBLAZERS WERE HAVING THIS PROBLEM AND THAT WE NEEDED TO CALL GM. I DID. THE PART HAS...

TL*THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 30 MPH, THE CONTACT NOTICED THAT THE SPEEDOMETER INDICATED THAT THE VEHICLE WAS TRAVELING 80 MPH. A FEW DAYS LATER, THE SPEEDOMETER FUNCTIONED PROPERLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE FAILURE MILEAGE WAS UNKNOWN.

TACHOMETER QUIT WORKING THEN 3 MONTHS LATER THE SPEEDOMETER QUIT WORKING. *TR

INSTRUMENT CLUSTER ON 2003 CHEVY TRAILBLAZER. RPM GAUGE STARTED DOESN'T REGISTER CORRECTLY NOW THE SPEEDOMETER IS NOT FUNTIONING EITHER. *LN

THE SPEEDOMETER ON MY 2003 CHEVROLET TRAILBLAZER IS INACCURATE. IT WILL READ VARIOUS SPEEDS AT ALL TIMES. FROM A STAND STILL, IT WILL READ ANYWHERE BETWEEN 10 TO 80 MPH. *TR

STEPPER MOTOR IN MY 2003 CHEVY TRAILBLAZER WITH APPROXIMATELY 146000 MILES WENT BAD. DOES NOT READ CORRECT FUEL LEVEL. DEALER STATED THAT FUEL SENDER UNIT WAS WORKING THAT THE WHOLE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. HAVE SEEN ONLINE THAT MANY TRAILBLAZER OWNERS ARE REPORTING SIMILAR ISSUES. WAS TOLD MANY OTHER GM VEHICLES WITH SAME INSTRUMENT CLUSTERS HAVE FAILED AND WERE REPLACED VIA RECALL. *LN

I HAVE A CHEVROLET TRAILBLAZER 2003. I WAS DRIVING THE VEHICLE AS USUAL. THE SPEEDOMETER QUIT WORKING AND OTHER VARIOUS LIGHTS ON MY DASH BOARD LIT UP, I.E. CHANGE OIL LIGHT, CHECK ENGINE LIGHT. A CHEVROLET DEALER CHECKED THE VEHICLE AND TOLD ME IT WAS THE INSTRUMENT PANEL CLUSTER AND THAT IT WOULD BE ABOUT $420,00. IT WORKS PERIODICALLY FOR A FEW DAYS AND THEN GOES BACK OUT AGAIN. I HAVE CHECKED THE WEB SITE AND CHEVROLET KNOWS ABOUT THIS AND HAD A RECALL FOR A SHORT TIME AND DID NOT NOTIFY ITS CUSTOMERS. I ONLY FOUND ABOUT THIS WHEN A FRIEND ALSO HAD THE SAME PROBLEMS WITH HER TAHOE AND SHE HAD TALKED TO A MECHANIC WHO SAID HE FIXED THE SAME PROBLEM FOR ONE OF HIS CUSTOMERS AND FOUND OUR THAT THERE HAD BEEN A RECALL THAT CHEVROLET DID NOT NOTIFY IT'S CUSTOMERS. MY HUSBAND AND I HAVE...

TL*THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE INSTRUMENT CLUSTER MALFUNCTIONED. THE CONTACT WAS UNABLE TO READ THE FUEL GAUGE, SPEEDOMETER, TEMPERATURE GAUGE, AND OIL PRESSURE GAUGE BECAUSE THEY WERE NO LONGER WORKING. THE CONTACT CALLED THE DEALER REGARDING THE INSTRUMENT CLUSTER. THE DEALER STATED THAT SINCE THE WARRANTY HAD EXPIRED THERE WAS NOTHING THEY COULD DO. THE CONTACT HAD NOT CALLED THE MANUFACTURER. THE CONTACT STATED THAT THIS WAS A SAFETY ISSUE AND A MANUFACTURERS DEFECT THAT NEEDED TO BE ADDRESSED. THE FAILURE MILEAGE WAS 94,000.

THE PROBLEM IS THIS. I WENT TO GO SOMEWHERE AT 5 AM IT WAS 44 DEGREES AND RAINING. A LIGHT CAME ON THAT SAID "ICE ON THE ROADWAY" ANOTHER LIGHT CAME ON THAT SAID "ENGINE POWER REDUCED" SO HERE I AM GOING UNDER 5 MILES PER HOUR ON THE FREEWAY. ITS 44 DEGREES AND NO ICE. IT HAS BEEN DOING THIS EVERY SINCE I BOUGHT IT NEW IN 2003. I HAVE TOLD THEM EVERY TIME I TAKE IT IN FOR A LUBE AND OIL CHANGE BUT THEY IGNORE ME BECAUSE THEY DO NOT KNOW HOW TO FIX IT.

TL*THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. WHILE THE VEHICLE WAS PARKED THE RPMS STOPPED WORKING AND IN A YEAR THE SPEEDOMETER STOPPED WORKING. WHILE THE VEHICLE WAS PARKED THE SPEEDOMETER DISPLAYED 80 MPH. THE VEHICLE WAS TAKEN TO A LOCAL MECHANIC AND WHO ADVISED HER THAT THE STEP MOTOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. SHE CONTACTED THE MANUFACTURER AND WAS ADVISED THAT THERE WAS NO RECALL FOR THE FAILURE. THE FAILURE AND CURRENT MILEAGE WERE APPROXIMATELY 120,000.

STARTING IN NOVEMBER 2008 WHILE LIVING IN MINNESOTA, THE INSTRUMENT CLUSTER ON MY 2003 CHEVY TRAILBLAZER STARTED SHOWING INCORRECT READINGS. FIRST, THE SPEEDOMETER, THEN AT ONE TIME OR ANOTHER, MOST OF THE GAUGES LIKE FUEL, TEMP, AND OIL PRESSURE. THE SPEEDOMETER WOULD READ 100 MPH WITH THE CAR STOPPED. AFTER WINTER, THE GAUGES AND SPEEDOMETER RETURNED TO NORMAL WITH ONLY AN OCCASIONAL BAD READING. I MOVED TO FLORIDA IN 2009, AND WENT ABOUT SIX MONTHS WITH NO ISSUES, BUT STARTING SUMMER OF 2010, THE ERRATIC SPEEDOMETER READINGS STARTED AGAIN. I CONTACTED CHEVY AND WAS TOLD A SIMILAR PROBLEM HAD BEEN THE SUBJECT OF A RECALL FOR TAHOES AND OTHER VEHICLES, BUT THAT THE TRAILBLAZER WAS NOT INCLUDED IN THE RECALL, AND I WOULD HAVE TO PAY THE +/- $700 REPAIR BILL MYSELF. *TR

FUEL GUAGE READS PAST FULL WHEN NOT, FUEL GAUGE READS EMPTY WHEN FULL SPEEDOMETER READS 114 WHEN AT STOP, NEEDLE POINTS DOWN WHEN AT HIGHWAY SPEED NOTHING DONE TO CORRECT FAILURE AT THIS TIME. *TR

SPEEDOMETER ON OUR 2003 CHEVROLET TRAILBLAZER STARTED ACTING ERRATICALLY--NEVER GOING DOWN TO ZERO, GOING UP TO 80 OR ABOVE FOR NO REASON, ETC.--ABOUT 2 YEARS AGO. IN A MATTER OF WEEKS, AFTER THE FIRST ONSET OF THE PROBLEM, IT STOPPED WORKING ALTOGETHER AND HAS NOT MOVED ABOVE ZERO SINCE. WE WERE TOLD THAT THE WHOLE INSTRUMENT CLUSTER WOULD HAVE TO BE REPLACED TO FIX THE ISSUE WITH THE SPEEDOMETER. LUCKILY, ALL OF THE OTHER GAUGES ARE STILL FUNCTIONING PROPERLY AS OF RIGHT NOW BUT FROM WHAT I HAVE FOUND IN MY RESEARCH OF THIS ISSUE IT SEEMS TO BE ONLY A MATTER OF TIME BEFORE THEY ALL WILL CEASE TO FUNCTION PROPERLY AS WELL. I HAVE SEEN AND READ MANY REPORTS ABOUT THIS PROBLEM BUT I AM SURE IT WOULD BE SAFE TO SAY THAT THERE ARE MANY MORE INSTANCES THAT HAVE GONE UNREPORTED. PLEASE LOOK INTO THIS VERY SERIOUS...

IN JULY 2010 MY TRAILBLAZERS CLUTCH FAN AND THERMOSTAT WENT OUT. I WAS ABLE TO DIAGNOSE THE PROBLEM BY THE NUMBER OF COMPLAINTS FILED ON THIS MODEL THAT WERE ON THE INTERNET. THEN IN OCTOBER MY TACHOMETER STARTED ACTING UP, IT BROKE NOVEMBER 24, 2010. THE SPEEDOMETER BROKE ON DECEMBER 3, 2010. I HAVE FOUND MANY COMPLAINTS ON THE CLUTCH FAN GOING OUT AND THE CLUSTER GOING OUT ON THE INTERNET. SOMEONE AT WORK HAD A PROBLEM WITH THEIR ENVOY AND IT WAS THE THERMOSTAT AND THEIR CLUTCH FAN GOING OUT. ALL AT FAIRLY LOW MILEAGE. I AM VERY DISAPPOINTED IN GM FOR NOT WANTING TO REPAIR THESE ISSUES SO THE CONSUMER BEARS THE COSTS OF REPAIR WHICH IS ABOUT 500 FOR THE CLUTCH FAN AND THERMOSTAT AND 400 FOR THE CLUSTER.

TL* THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 20 MPH THE SPEEDOMETER DISPLAYED THAT HE WAS TRAVELING 100 MPH. THE VEHICLE WAS NOT INSPECTED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 98,000.

2003 CHEVY TRAILBLAZER 2WD, LTZ - INSTRUMENT PANEL IS FAILING. BEGAN WITH THE SPEEDOMETER, WHICH DOES NOT ACCURATELY REFLECT THE CORRECT SPEED 100% OF THE TIME. NOW, THE OIL GAUGE IS NOT WORKING PROPERLY AND THE FUEL GAUGE IS OFF AS WELL. I CHECKED WITH CHEVROLET DIRECTLY (800 222 1020) AND WAS TOLD THAT THERE IS NOT A RECALL FOR THIS ISSUE. HOWEVER, FOR THE SAME YEARS, THE SILVERADO, AVALANCHE WERE RECALLED! IF IT'S AN ISSUE ACROSS CHEVY TRUCKS, THEN THE TRAILBLAZER SHOULD BE RECALLED AS WELL. *TR

SPEEDOMETER ON MY 2003 CHEVY TRAILBLAZER DOES NOT CALIBRATE TO ZERO WHEN STARTING VEHICLE. THIS IS CAUSING ERRONEOUS SPEEDOMETER DISPLAY WHEN OPERATING THE VEHICLE CAUSING SERIOUS SAFETY ISSUES. I HAVE READ SEVERAL OTHER COMPLAINTS OF THE EXACT ISSUE. A RECALL SHOULD BE ISSUED TO CORRECT THE PROBLEM WHILE THE NUMBER OF DEATHS REPORTED FOR THIS ISSUE IS STILL 0. DOES SOMEONE NEED TO DIE BEFORE THE PROBLEM IS ADDRESSED? *TR

TL * THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE INSTRUMENT CLUSTER MALFUNCTIONED WHILE DRIVING 25 MPH. THE SPEEDOMETER WOULD NOT READ ACCURATE SPEEDS TRAVELED AND THE FUELE LVEL INDICATOR WOULD NOT READ ACCURATE FUEL LEVELS. THE CONTACT STATED THAT THERE WERE NUMEROUS COMPLAINTS FOUND ONLINE REGARDING THE INSTRUMENT CLUSTER FAILURE AND STATED THAT THE MANUFACTURER SHOULD ISSUE A RECALL. THE CONTACT STATED THE FAILURE WAS A MAJOR SAFETY ISSUE. THE FAILURE MILEAGE WAS 82,000.

MY TACHOMETER WENT OUT ON MY 2003 CHEVY TRAILBLAZER ON 9-6-10. I HAVE AROUND 100,000 MILES ON THE VEHICLE, BUT THIS IS NOT THE FIRST OF MANY COMPLAINTS ON THIS VEHICLE. *TR
