  MY SPEEDOMETER STOPPED WORKING MY GAS GAIGE STOPPED WORKING AND MY ODOMETER WENT OUT CANT SEE THE MILELAGE AND I DONT KNOW HOW MUCH GAS IS IN THE TAKE,AND THE SPEED IS MOT WORKING.I REMEMBER A RECALL AWHILE AGO IF YOU HAD THE PROBLEM THEY SAID AND I DIDNT AT THAT TIME I THINK IT WAS 2011

• 12/31/2010· ELECTRICAL SYSTEM

  I CURRENTLY OWN A 2005 CHEVY TRAILBLAZER. OVER THE PAST YEAR I HAVE A VARIETY ELECTRICAL PROBLEMS WITH MY BLAZER. IN THE JANUARY OF 2010 I HAD TO REPLACED BY AC / HEATER AS IT SIMPLY WENT OUT. WHEN THE VEHICLE WAS FIXED A CERTIFIED MECHANIC HE SHOWED US THE WIRING HARNESS THAT HAD SIMPLY MALFUNCTIONED AND MELTED ALL OF THE WIRES TOGETHER. NOW IN THE PAST THREE MONTHS MY GAS GAUGE HAS STOPPED WORKING, INDICATING THAT IT IS LOW ON FUEL OR EMPTY AND MY SPEEDOMETER IS NO LONGER FUNCTIONING. I AM VERY WORRIED ABOUT THE ELECTRICAL PROBLEMS AND THE RISK OF A POTENTIAL HAZARDS TO MYSELF AND MY FAMILY. *TR

• 12/31/2010· UNKNOWN OR OTHER

  THE OIL LEVEL INDICATOR IN THE DASH PANEL IS NO LONGER FUNCTIONING. A CALL TO THE DEALER WHERE CAR WAS PURCHASED CONFIRMS THAT THIS IS PART OF AN "INSTRUMENT CLUSTER" THAT ALSO CONTROLS THE SPEEDOMETER, AND THAT IT WILL PROBABLY MALFUNCTION AS WELL.

• 12/31/2009· ELECTRICAL SYSTEM

  THE SPEEDOMETER IN MY 2005 CHEVY TRAILBLAZER HAS BROKEN AND I ONLY HAVE 45,000 MILES ON MY VEHICLE. I HEARD ABOUT A RECALL OR GETTING ASSISTANCE FROM GM TO REPLACE BUT LEARNED IT IS ONLY FOR TAHOE'S, SUBURBAN'S AND TRUCKS. I DON'T FEEL THAT IS FAIR THEY WON'T HELP ME AND THAT A SPEEDOMETER SHOULD NOT WEAR OUT THAT QUICKLY. REPLACEMENT COST CAN BE $600 - $800. *TR

  THE HEADLIGHTS/DASH LIGHTS STARTED FLICKERING. THE BATTERY VOLTAGE METER WAS JUMPING BACK AND FORTH. THE HEADLIGHTS WOULD GO OUT AND THEN COME BACK ON. I WAS NOT ABLE TO DUPLICATE THIS PROBLEM. THERE WERE NO CODES STORED IN THE COMPUTER FROM THE INCIDENT. IT HAS HAPPENED SINCE 11/23/05 AT LEAST TWICE. *JB

  FOR SEVERAL YEARS THE LOW BEAM HEADLIGHTS WOULD GO OFF AND ON INTERMITTENTLY. NOW, THEY ARE MOSTLY OFF WHICH MEANS I CANNOT DRIVE MY VEHICLE AT NIGHT ANYMORE UNLESS I WANT TO BLIND PEOPLE OR GET STOPPED. I HAVE CHANGED HEADLAMPS, RELAYS AND FUSES TO NO AVAIL. NOW, I SEE THAT MANY OTHERS WITH THE SAME MAKE AND MODEL SUV HAVE BEEN HAVING THE SAME ISSUE BUT NO RECALLS HAVE BEEN ISSUED FOR THIS YEAR MODEL. THIS IS A MAJOR SAFETY ISSUE WHEN WE HAVE TO DRIVE WITH THE HIGH BEAMS ON AND WHEN THE LIGHTS GO OFF UNEXPECTEDLY. IF YOU WILL ISSUE A RECALL FOR ONE YEAR MODEL HAVING A PARTICULAR ISSUE, WHY WOULD YOU NOT DO THE SAME WITH ALL YEAR MODELS HAVING THE SAME ISSUE? COME ON CHEVROLET AND NHTSA, LET'S GET THIS PROBLEM SOLVED TO SAVE SOME LIVES. IT IS VERY SCARY TO BE DRIVING AND HAVE YOUR HEADLIGHTS GO OUT AND A MAJOR PAIN TO HAVE TO BE SURE YOU ARE HOME BY DARK OR NOT BE ABLE TO GO OUT AFTER DARK BECAUSE YOUR HEADLAMPS ARE OR MAY STOP WORKING.

• 12/30/2018· ELECTRICAL SYSTEM

  I AM EXPERIENCING ALL ISSUES IDENTIFIED WITH RECALL DUE TO DOOR SWITCH SENSOR BEING DEFECTIVE. INTERMITTENT WORKING OF DOOR LOCKS NOT LOCKING OR LOCKING AND WON'T UNLOCK . WINDOWS WON'T WORK SOMETIMES, AND SOMETIMES THEY WILL . LIGHTS WON'T SHUT OFF IN INTERIOR, OR WON'T GO ON . DELAY FEATURE WHERE RADIO , AND OTHER FEATURES STAY ON AFTER TURNING IGNITION OFF , AND STILL IN VEHICLE WON'T WORK , AND SOMETIMES DO WORK . THESE THINGS HAPPEN WHEN VEHICLE IS EITHER MOVING, OR NOT MOVING IN PARK . THEY HAPPEN BOTH CITY DRIVING, AND HIGHWAY AS WELL. ALL OF THESE CRAZY ELECTRICAL PROBLEMS BEGAN SEVERAL MONTHS AGO, AND WHEN IN THE VEHICLE AND I AM IN PARK, AND SHUT OFF IGNITION, AND THE DOORS WON'T UNLOCK, THE KEY FOB WON'T WORK TO UNLOCK DOORS EITHER, AND I AM TRAPPED INSIDE VEHICLE UNTIL SOMEONE IS CLOSE ENOUGH TO HEAR ME YELLING FOR HELP, AND CAN HAND THEM MY KEYS OUT OF SUNROOF IN ORDER TO PUT IT INTO LOCK ON THE DOOR AND MANUALLY UNLOCK THE DOOR. I ABSOLUTELY MUST HAVE THIS FIXED BECAUSE NOBODY NEAR MY RESIDENCE TO EITHER LET ME OUT OF VEHICLE, OR TO CALL . CLOSEST PERSON I CAN CALL IS OVER AN HOUR AWAY . I AM ON DISABILITY OF 720.00 A MONTH AND CAN'T AFFORD THIS REPAIR .

IT ALSO REVS BY ITSELF, EVEN IN PARK AND WILL GO FORWARD SLIGHTLY WHEN IT DOES SURGE. THESE PROBLEMS ONLY STARTED AFTER THE ALTERNATOR WAS REPLACED.

  LOW BEAM HEADLIGHTS HAVE FLASHED ON MULTIPLE OCCASIONS IN THE PAST. ON THE NIGHT OF OCTOBER 2, 2014, WHILE DRIVING HOME WITH MY ENTIRE FAMILY IN THE CAR, THE LOW BEAM HEADLIGHTS WENT OUT COMPLETELY. I TURNED ON MY FOG LAMPS TO GET HOME. I CHECKED ALL FUSES AND RELAYS AND THERE WERE NO PROBLEMS. I ALSO TOOK IT TO A MECHANIC, WHO SECURED A LOOSE GROUND WIRE. THIS DID NOT HELP. THEN I HEARD THAT GM WAS DOING A RECALL FOR THIS EXACT PROBLEM, BUT IT IS FOR MODELS 2006-2007, AND MINE IS A 2005. THEY WILL NOT HONOR THE RECALL ON MY VEHICLE. I AM AFRAID TO TAKE MY VEHICLE ANYWHERE AT NIGHT OR IN THE RAIN. I DO NOT FEEL I SHOULD HAVE TO PAY FOR THE REPAIR WHEN THEY KNOW IT IS AN ISSUE. *TR

I HAVE RUN OUT OF GAS SEVERAL TIMES SINCE THEM BECAUSE THIS IS NOT THE MOST ACCURATE METHOD.

  IN 2007 I PAID OFF MY VEHICLE AND NOW BECAME THE PROUD OWNER OF MY TRUCK. IN 2009, I NOTICED SOME PROBLEMS WITH MY TRUCK. FIRST, THE GAS GAUGE WOULD SAY "F" FULL, BUT REALLY IT WAS ON "E" EMPTY. THEN THE MILEAGE GAUGE ? I CAN BE ON THE EXPRESSWAY GOING AS FAST AS THE OTHER CARS, BUT MY CAR READS 20 MPH. THIS IS CRAZY!!!! I CALLED AT 800-NUMBER FOR GMC AND WAS INFORMED THAT THERE WAS NO RECALLS OR ANY OTHERS CALLS FOR THE 2005 TRAILBLAZER, WHICH I KNEW WAS A HUGE LIE!!!! I DECIDED TO GO ON LINE AND GOOGLE THE MAKE AND MODEL OF MY CAR. WOW? GUESSES WHAT I SEEN? THERE WERE OVER 41,000 PEOPLE WHO HAVE THE SAME PROBLEMS THAT I HAD FOR THEIR 2005 TRAILBLAZER. AGAIN, THE PROBLEM WITH MY TRUCK HAS GOTTEN WORST. IN 2010, I CALLED AGAIN AND WAS INFORMED THAT THEIR STILL WASN'T ANY OTHER CALLS OR CONCERNS WITH MY TRUCK AND THAT I SHOULD TAKE IT TO AN AUTHORIZE CHEVY DEALERSHIP. WELL, I DID .. . IN 2011, I CALLED AGAIN.. SAME SCRIPT SAME STORY!!! I RECEIVED A LETTER FOR A EMISSION TEST FOR MY CAR. WELL, LET ME TELL YOU WHEN I TOOK MY VEHICLE UP TO THE EMISSION TESTING IT FAILED!!! . I GOT AN ESTIMATE COST OF $ 1900, PLUS THEY FOUND 3 ADDITIONAL CODES. . WELL, I GOT A 2008 CHEVY IMPALA. I WENT FROM PAYING NO CAR NOTE, TO $381.00 A MONTH NOTE. THE WEEK OF SEPTEMBER 4TH, 2011.. I RECEIVE A LETTER FROM CHEVROLET ADDRESSING THE ISSUES WITH THE 2005 CHEVY TRAILBLAZERS, AND OFFERING 50% ON REPAIRS FOR THE SAME PROBLEMS THAT I HAVE BEEN CALLING ON FOR 2 YEARS.

  SPEEDOMETER JUMPS ALL OVER THE PLACE. EVERYDAY NOW IT WILL JUMP FORWARD. WHEN I STOP AT A STOP LIGHT IT WILL STICK AT SOME MPH NOT GOING TO ZERO. THEN WHEN I TAKE OFF IT WILL START WHERE IT HALTED AT. SO IF IT STOPS AT 35MPH THEN WHEN I GET TO 55 PER MY GPS THE SPEEDOMETER WILL SHOW I'M GOING 90. SOMETIMES I'M GOING 120MPH IT'S ALL OVER THE PLACE AND IT HAPPENS EVERYDAY NOW. I WAS READING ON-LINE AND SEE THIS IS AN ON GOING PROBLEM WITH TRAILBLAZERS. *TR

WE CONTACTED TWO LOCAL GARAGES AND THEY SAY THAT THIS IS A NORMAL OCCURRENCE FOR TRAILBLAZERS, AND THAT THE HEADLIGHT SOCKET NEEDS TO BE REPLACED. I HAVE SEEN MULTIPLE COMPLAINTS ONLINE COMPLAINING ABOUT THIS SAME ISSUE. I AM ASTOUNDED THAT THERE IS NOT A SAFETY RECALL ADDRESSING THE TOTAL LOSS OF THE USE OF THE HEADLIGHTS!

I HAVE 5 SMALL KIDS AND SOMEONE IS GOING TO GET HURT BECAUSE THIS VEHICLE IS DEFECTIVE AND NO ONE WANTS TO TAKE RESPONSIBILITY TO FIX IT.. SO NOW WHEN IS SOMEONE GOING TO FIX THIS PROBLEM ?IF I SPEND $24,000 ON THIS USED VEHICLE WITH ONLY 30,000 MILES ON IT WHEN I BOUGHT IT FEB 2008 IT COULD AT LEAST RUN DECENT..YOU WOULD THINK IT WOULD BE CHEAPER FOR CHEVROLET TO FIX THIS VEHICLE THAN TO HAVE A LAWSUIT. *TR

  2005 CHEVROLET TRAILBLAZER...A COUPLE OF DAYS AGO, WHILE MY 15 YEAR OLD DAUGHTER WAS DRIVING THIS TRUCK THE SPEEDOMETER GOT STUCK ON 10MPH AND SHE COULD NOT TELL HOW FAST SHE WAS REALLY DRIVING. WE WERE ON A BACK COUNTRY ROAD (THANK GOD) NOT IN HEAVY TRAFFIC BUT I KNOW SHE HAD TO BE GOING AT LEAST 45MPH. SHE HAS JUST GOTTEN HER LEARNER'S PERMIT A FEW WEEKS EARLIER AND DID NOT HAVE MUCH EXPERIENCE DRIVING SO THIS REALLY FREAKED HER OUT. NOW THE SPEEDOMETER WILL WORK WHEN YOU FIRST START THE TRUCK BUT IF YOU COME TO A STOP IT WILL STICK AGAIN AND AT TIMES IT WILL READ HIGHER THAN WHAT I AM ACTUALLY TRAVELING. LIKE THIS MORNING, UPON STARTING THE TRUCK BEFORE IT WAS EVER PUT INTO DRIVE THE SPEEDOMETER READ 10MPH. THIS COULD BE A VERY HAZARDOUS DEFECT AND GM SHOULD RECALL THIS PROBLEM AND FIX IT. IN RESEARCHING, I SEE THAT THERE HAVE BEEN MANY COMPLAINTS ABOUT THE SPEEDOMETERS IN THESE TRUCKS, YET GM HAS DONE NOTHING TO RESOLVE THE PROBLEM. IT IS COSTING CONSUMERS APPROX. $500-$750 TO REPAIR. I HAVE GOTTEN AN ESTIMATE OF $600 MYSELF BUT HAVE NOT HAD THE REPAIRS COMPLETED YET. NO MONEY TO DO SO AND HOPING MY WARRANTY WILL COVER IT. *TR

THIS COULD BE VERY DANGEROUS IF YOU ARE ON THE HIGHWAY OR TRYING WATCH YOUR SPEED IN A NEIGHBORHOOD. I HAVE SEEN LOTS OF COMPLAINTS ABOUT THIS PROBLEM.

THE DOOR LOCKS (INCLUDING HATCHBACK) DO NOT ALWAYS UNLOCK WHEN CAR IS STOPPED, AND INTERIOR LIGHTS AND RADIO SOMETIMES STAY ON. ALL GAUGES (GAS, OIL, TEMPERATURE, ETC) GO TO ZERO. AFTER TALKING TO A MECHANIC FRIEND, WE TOOK THE DASHBOARD APART, PULLED OUT THE CLUSTER AND PUT IT BACK IN. THAT APPEARS TO HAVE STOPPED THE PROBLEM FOR NOW, BUT WE HAVE NOT USED THE VEHICLE MUCH SINCE DOING THE REPAIR. WE HAVE BEEN TOLD IT COULD REQUIRE A NEW CLUSTER COSTING IN THE $400 RANGE NOT INCLUDING LABOR.

  NIGHT DRIVING UNDER NORMAL CIRCUMSTANCES THE VEHICLE A CHEVROLET TRAILBLZER LS 2005 HAS A PROBLEM THAT RANDOMLY SHUTS OFF THE HEADLIGHTS AND DASHBOARD LIGHTS. THE TRAILBLAZER DECIDES TO DO THIS TOTALLY ON ITS OWN AT RANDOM. THIS CAUSES A POTENTIALLY DEADLY SITUATION WHEN ON THE INTERSTATE AND YOUR HEADLIGHTS GO OUT AND DECIDE TO COME BACK ON AT RANDOM INTERVALS MAYBE APROXIMATELY 15 TO 20 SECONDS APART. SEVERAL ATTEMPS HAVE BEEN MADE TO THE CHEVROLET DEALERSHIP TO GET THE PROBLEM REPAIRED. THEIR COMMENT IS THAT THEY EITHER CANNOT DUPLICATE THE PROBLEM OR THEIR IS A SERVICE BULLETIN THAT EXPLAINS THE ISSUE. I HAVE DONE THE PROCEDURES THAT THE DEALERSHIP DESCRIBED IN THE SERVICE BULLETINS WITH NO SUCCESS. CURRENTLY MY TRAILBLAZER IS BEING REPAIRED ONCE AGAIN AT TERRY LEE CHEVROLET AS OF 12-19-06. THE LAST TIME THAT THE VEHICLE WAS IN FOR REPAIR TERRY LEE CHEVROLET REPLACED WHAT THEY HAD THOUGH WAS A FAULTY BODY CONTROL MODULE. REPLACING THIS MODULE OBVIOUSLY DID NOT RECTIFY THE PROBLEM AND ON THURSDAY 12-14-06 THE PROBLEM ONCE AGAIN RETURNED. SINCE THE VEHICLE IS USED TO TRANSPORT MY CHILDEREN AND WIFE WHO HAVE BEEN DRIVING PRIMARILY AT NIGHT. I HAVE BECOME SKEPTICAL ABOUT WHETHER OR NOT THE VEHICLE IS SAFE TO ACTUALLY DRIVE AT NIGHT BECAUSE YOU NEVER KNOW WHEN THE LIGHTS WILL DECIDE TO TURN OFF BY THEMSELVES AND POTENTIALLY CAUSE THEM TO BE IN AN ACCIDENT. *NM

  MY 2005 TRAILBLAZER'S SPEEDOMETER WILL STOP WORKING WHILE I AM DRIVING. IT SEEMS AS THOUGH IT GETS TOO HOT EITHER FROM THE HEATER BEING ON OR IF I AM DRIVING A LONG DISTANCE AND IT WILL HIT A CERTAIN POINT AND THE SPEEDOMETER WILL JUST STOP WORKING. THE FIRST TIME THIS HAPPENED I WAS ON MY WAY TO CALIFORNIA FOR THANKSGIVING AND IN THE MIDDLE OF MY DRIVE I LOOKED DOWN AND I HAD TAKEN MY FOOT OFF THE GAS AND INSTEAD OF MY TRAILBLAZER SLOWING DOWN THE SPEEDOMETER KEPT RAISING. I HAD TO RELY ON MY SPEED BY MY RPM'S. I WAS ABLE TO USE THE FUSE BOX TO RESET THE SPEEDOMETER AND IT STARTED WORKING AGAIN FOR ONLY A SHORT TIME AND THEN IT STOPPED WORKING AGAIN. I HAD TO REPEAT THIS PROCESS ABOUT 5 TIMES THAT WEEKEND. SINCE THANKSGIVING WEEKEND IT HAS HAPPENED SEVERAL MORE TIMES ONLY INSTEAD OF RAISING IN SPEED THE SPEEDOMETER WILL STAY BETWEEN 0-30 MILES PER HOUR WHEN ACCORDING TO MY RPM'S I SHOULD BE GOING ABOUT 65 OR 70 MPH. I CAN TURN OFF MY TRAILBLAZER AND LET IT COOL OFF AND THEN THE SPEEDOMETER WILL START WORKING AGAIN. I HAVE FOUND SEVERAL PLACES ONLINE WHERE TRAILBLAZER OWNERS HAVE COMPLAINED ABOUT THE SAME PROBLEM. IT WILL COST SEVERAL HUNDRED DOLLARS TO FIX, BUT IF OTHER TRAILBLAZERS ARE HAVING THE SAME PROBLEM THEN THERE IS OBVIOUSLY A DEFECT WITH THE SPEEDOMETER WHICH SHOULD BECOME A NATIONAL RECALL. IT IS NOT FUN DRIVING AND THINKING YOU ARE GOING ONE SPEED WHEN YOU ARE NOT, AND I AM SURPRISED THERE HAVEN'T BEEN MULTIPLE CAR ACCIDENTS FROM THIS PROBLEM. THE DRIVER'S ELECTRICAL PANEL SHOULD NOT FAIL IN A CAR AND THAT IS A HUGE SAFETY CONCERN!!!! *TR
