2005 Chevrolet Trailblazer complaints

HEAD LIGHTS DIM AND BRIGHTEN WHILE DRIVING. WITH NO REASON THE LIGHTS GET VERY DIM AND A SECOND LATER THE LIGHTS BRIGHTEN AND THIS CYCLES OVER AND OVER. THIS IS VERY UNSAFE. OTHER DRIVERS THINK I WANT THEN TO STOP OR SLOW DOWN OR PULL OVER. *TR

THE FUEL GAUGE DOES NOT WORK PROPERLY. IT MAY SHOW EMPTY, QUARTER,OR HALF FULL EVEN THOUGH IT IS FULL. I SEE A LOT OF PEOPLE HAVE THIS PROBLEM. THERE SHOULD BE A RECALL!! IT'S NO WONDER THEY CAN'T SELL THEM!! *TR

FUEL GAUGE DOES NOT FUNCTION FOR 2005 CHEVY TRAILBLAZER. POTENTIAL TO RUN OUT OF FUEL IN SUBZERO WEATHER ENDANGERING OCCUPANTS. THIS IS WELL KNOWN AND COMMON PROBLEMS WITH THIS MODEL. *TR

SPEEDOMETER DOES NOT READ CORRECTLY. READS AT 120 MPH REGARDLESS WHAT SPEED YOU ARE DRIVING. HAVE READ ABOUT TOO MANY COMPLAINTS REGARDING THIS SAME PROBLEM. WHY NO RECALL? *TR

FUEL GAUGE DOES NOT READ PROPERLY. NEEDLE ON GAUGE FLOATS FROM EMPTY TO FULL AND WILL READ LOW FUEL WHEN TANK IS FULL. HAVE READ OF OTHER COMPLAINTS REGARDING THIS PROBLEM. WHY NO RECALL? *TR

AFTER I HAVE BEEN DRIVING FOR 20-30 MINUTES MY SPEEDOMETER STOPS FUNCTIONING. IN CITY DRIVING SITUATIONS, THE SPEEDOMETER NEEDLE DROPS TO ZERO AND STAYS THERE FOR THE ENTIRE TRIP. IN HIGHWAY DRIVING SITUATIONS WHEN THE CRUISE CONTROL IS IN USE, THE SPEEDOMETER "STICKS." WHEN I TOUCH THE BREAKS OR THE GAS TO SPEED UP/SLOW DOWN THE SPEEDOMETER NEEDLE STAYS AT WHATEVER SPEED I WAS PREVIOUSLY DRIVING AND STAYS THERE FOR THE REST OF THE TRIP. ONCE THE CAR HAS BEEN PARKED AND TURNED OFF FOR APPROXIMATELY AN HOUR, THE SPEEDOMETER CAN BE RESET BY STARTING THE CAR AND TURNING IT OFF UNTIL THE NEEDLE RETURNS TO ZERO. THIS PROBLEM STARTED WHEN MY TRAILBLAZER HAD APPROXIMATELY 55,000 MILES AND HAS PERSISTED SINCE. THE DEALERSHIP TOLD ME THAT THIS PROBLEM ISN'T COVERED UNDER THE WARRANTY AND I WOULD BE RESPONSIBLE FOR THE $450-550 COST TO REPLACE THE INSTRUMENT CLUSTER. THEY ALSO SAID THAT THIS IS A PREVALENT PROBLEM WITH 2005 TRAILBLAZERS BUT IT WON'T BE COVERED UNDER A SILENT WARRANTY UNLESS MORE COMPLAINTS ARE FILED. THIS IS A SERIOUS AND POTENTIALLY DANGEROUS PROBLEM THAT CAN CAUSE SERIOUS ACCIDENTS AND DEATHS, AND I BELIEVE CHEVY SHOULD BE RESPONSIBLE FOR ENSURING THEIR VEHICLES ARE SAFE FOR THEIR CUSTOMERS TO DRIVE. *TR

MY SPEEDOMETER ISN'T WORKING PROPERLY AND I CAN BE GOING APPROXIMATELY 60 MILES PER HOUR ON THE HIGHWAY AND THE GAUGE SHOWS THAT I AM GOING 25/30 MILES AN HOUR AND I RESEARCHED THIS ON THE INTERNET AND IT SHOWS OTHER COMPLAINTS RELATING TO THE SAME PROBLEM...WHY HASN'T GM RECALLED THIS PROBLEM ON THE 2005 MODELS? *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE DRIVING 35 MPH, THE CONTACT NOTICED THAT SHE WAS NOT TRAVELING AS QUICKLY AS THE OTHER VEHICLES ON THE ROAD. THE SPEEDOMETER READ 120 MPH. SHE TOOK THE VEHICLE TO THE DEALER AND THEY STATED THAT THE INSTRUMENT PANEL FAILED. THE DEALER WILL REPLACE THE INSTRUMENT PANEL. THE VIN WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 46,000.

MY 2005 TRAILBLAZERS HEADLIGHTS FLASH WHEN YOU LET UP OFF THE GAS PEDAL. ALSO, THE AMP GAUGE DROPS, THE ENGINE REVS DOWN AND THE INSIDE FANS AND LIGHTS DIM DOWN. THE FLASHING OF THE HEADLIGHTS IS GETTING WORSE, AND LIKE OTHERS HAVE REPORTED, THE TRAFFIC AHEAD THINKS YOU ARE BLINKING THEM TO EITHER PULL OVER, OR SPEED UP. I TOO NOTICE IT MORE IN THE COLDER MONTHS. I AGREE -THIS IS DEFINITELY A SAFETY HAZARD! SOMETHING NEEDS TO BE DONE ABOUT IT. I HAVE REPORTED THE PROBLEM, BUT THEY SAY NOTHING CAN BE DONE. PURCHASED THIS SUV BRAND NEW, HAD PROBLEM FROM THE BEGINNING. TOO MANY PEOPLE WITH SAME PROBLEM. GENERAL MOTORS SHOULD BE ASHAMED. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL PUMP IN THE TANK BECAME HOT ENOUGH TO DETERIORATE THE INSULATION ON THE WIRES. AS A RESULT, THE FUEL GATE UNIT MALFUNCTIONED. THE MANUFACTURER STATED THAT THEY WOULD REPAIR THE FAILURE AT $350, WHICH IS HALF OF THE PRICE THEY ARE CHARGING. THE FAILURE AND CURRENT MILEAGES WERE 50,000.

MASSIVE ELECTRICAL PROBLEMS WITH CHEVY TRAILBLAZER 1. WHILE GOING 10 MILES AN HOUR, THE SPEEDOMETER JUMPS TO 120MPH THEN TO 50MPH THEN TO 120MPH AGAIN. 2. WHEN I FILL UP WITH GAS, THE GAS GAUGE STATES THAT THE TANK IS STILL EMPTY THEN MOVES TO FULL THEN TO A 1/4 THEN TO FULL THEN TO HALF ETC... 3. WHILE DRIVING AT NIGHT, MY HEADLIGHTS GO HIGHBEAM TO LOW BEAM AS IF I AM MANUALLY FLASHING MY LIGHTS AT OTHER CARS. I HAVE READ ON THE INTERNET WHERE THIS IS HAPPENING TO MANY MANY PEOPLE WITH THIS SAME MODEL OF CHEVROLET SUV AND THAT GM REFUSES TO DO ANYTHING ABOUT THIS. -I CALLED GM AND ADVISED THEM OF THE ENTIRE ISSUE. THEY ADVISED ME TO GO TO A DEALERSHIP AND HAVE THEM RUN A DIAGNOSTIC AS THIS WAS NEEDED BEFORE THEY COULD HELP ME. -I WENT TO THE DEALER AND PAID $115 FOR THE DIAGNOSTIC, NEEDLESS TO SAY THE REPAIRS THAT THE DEALER FOUND RANGER OVER $3000.00 DOLLARS. -I THEN CALLED GM BACK AND THEY TOOK THE INFORMATION THAT THE DEALER GAVE ME (DONNA AT 1-866-790-5700 X21153) -I JUST GOT A CALL BACK FROM GM STATING THAT BECAUSE OF THE MILEAGE ON THE SUV THAT THEY WERE NOT GOING TO DO ANYTHING (THEY KNEW ABOUT THE MILEAGE BEFORE THEY SENT ME TO THE DEALERSHIP!). SO I WASTED $115 DOLLARS FOR SOMETHING THAT WAS NOT NEEDED BY GM, AND THE FACT THAT THEY KNEW ABOUT THE MILEAGE TO START OFF WITH IS A WAY TO LET THE DEALER MAKE SOME MONEY OFF THE CONSUMER. *TR

I HAVE A 2005 CHEVROLET TRAILBLAZER LS V6, AND I WAS GOING DOWN THE INTERSTATE WHEN I NOTICE MY SPEEDOMETER READ 30 MPH. I KNEW I WAS GOING FASTER THAN THIS SO I PULLED OVER TO THE SIDE OF THE ROAD AND CUT THE ENGINE OFF AND RESTARTED IT. IT BEGAN TO WORK FINE UNTIL THE FOLLOWING MONDAY EVENING WHEN IT DID IT AGAIN, THIS TIME ONLY REGISTERING 0 MPH WHEN I WAS DRIVING APPROXIMATELY 30 MPH. FINALLY ON 01/13/08, I GOT IN IT TO GO TO WORK AND IT WAS REGISTERING 120 MPH BUT THE VEHICLE WAS AT A STANDSTILL. *TR

I HAVE A 2005 TRAILBLAZER AND THE SPEEDOMETER IS NOT WORKING CORRECTLY SOMETIMES IS STAYS ON ZERO AND THEN THERE ARE TIMES IT READS 120MILES WHEN IM GUESSING I'M GOING AROUND 30 MILES AND THERE ARE TIMES WHEN IN PARK IT READS ANY WHERE FROM 40 TO 60 MPH. HAS OF NOW I DO NOT HAVE THE MEANS TO FIX THE PROBLEM AND NOT THAT I FEEL I SHOULD HAVE TO PAY OUT OF POCKET SEEING HOW I BELIEVE THIS IS A GM PROBLEM AND NOT MINE ARE THE OTHER HUNDREDS OF GM OWNERS WITH THE SAME PROBLEM! THIS IS A SAFETY ISSUE THAT SHOULD BE RESOLVED AS SOON AS POSSIBLE....OH AND IT IS A EVERYTIME I DRIVE THIS GM PRODUCT OCCURRENCE,,,I NEVER KNOW WHAT SPEED I AM TRULY GOING!!! *TR

2005 CHEVY TRAIL BLAZER. I'VE HEARD SEVERAL COMPLAINTS ON THIS SPEEDOMETER SUBJECT, AND FROM WHAT I UNDERSTAND IT CAN BE A VERY EXPENSIVE PROCEDURE, HOPEFULLY MY COMPLAINT CAN PUSH FOR A RECALL. *TR

MY DAUGHTER HAD AN ACCIDENT ON 12/16/2008. SHE HAS(HAD) A 2005 CHEVROLET TRAILBLAZER LS, 2 WHEEL DRIVE SUV. WHILE DRIVING ON THE OHIO TURNPIKE DURING A SNOW STORM SHE LOST CONTROL AND HAD A HEAD ON CRASH WITH A CEMENT RETAINING WALL WHILE TRAVELING BETWEEN 25 TO 35 MILES PER HOUR. THE AIR BAG DID NOT DEPLOY DURING THE ACCIDENT AND SHE SLAMMED HARD INTO THE STEERING WHEEL RESULTING IN A CONCUSSION, CHEST INJURIES, SORE WRIST, DIZZINESS, AND STILL HAS RINGING IN ONE EAR. SHE DID HAVE HER SAFETY BELT ON AT THE TIME OF THE ACCIDENT AND ALWAYS WEARS IT. WE ARE BAFFLED AS TO WHY THE AIR BAG DID NOT COME OUT AS IT WOULD HAVE SAVE HER MUCH PAIN. THE CAR IS A TOTAL WRECK AS DESCRIBED BY THE PONTIAC DEALER THAT HER INSURANCE COMPANY TOWED THE SUV TO FOR REPAIRS. THE TRAILBLAZER SUSTAINED MUCH DAMAGE SUCH AS A BENT FRAME, BROKEN TRANSMISSION, ALL OF THE MOTOR MOUNTS AND THE TRANSMISSION MOUNTS BROKE LOOSE FROM THE FRAME, BENT STEERING WHEEL, AND ALL PARTS FROM THE ENGINE FORWARD ARE EITHER GONE OR BENT BEYOND REPAIR. WITH THIS VIOLENT OF A CRASH NO ONE HAS BEEN ABLE TO TELL US WHY THE AIR BAGS DID NOT DEPLOY. WE BOUGHT THIS SUV USED FROM A CHEVY DEALER IN JULY OF 2005 AND IT HAD AROUND 8000 MILES ON IT AT THAT TIME. I WOULD LIKE TO KNOW IF THERE IS SOME WAY OF CHECKING THE FUNCTIONALLY OF THIS AIR BAG TO SEE IF THERE MAY BE A POSSIBLE PROBLEM WITH IT. HER CRASH WAS HEAD ON AND IN MY OPINION VIOLENT ENOUGH TO ACTIVATE THE DRIVER SIDE AIR BAG. ANY SUGGESTIONS AS TO WHAT WE SHOULD DO? *TR

05 CHEV. TRAILBLAZER SPEEDOMETER NOT WORKING. COMMON PROBLEM IN ALL MODELS OF THE TRAILBLAZER. GM NEEDS TO RECALL ALL MODELS AND FIX ACCORDINGLY. *TR

2005 CHEVY TRAILBLAZER SPEEDOMETER BROKEN ONLY HAS 29,540 MILES. ALL OF A SUDDEN IT STOP WORKING ONLY 3 YEARS OF OWNERSHIP, BROUGHT BRAND NEW. THIS IS AN EXPENSIVE PART TO PURCHASE AND VERY UNFAIR, ....*TR

SPEEDOMETER FAILS TO FUNCTION INTERMITTENTLY. MAY READ 0 MPH WHILE DRIVING AT FREEWAY SPEEDS, OR 100+ MPH WHILE AT A DEAD STOP. MAY READ NORMALLY AT OTHER TIMES. *TR

I WAS DRIVING DOWN THE ROAD DRIVING ABOUT 40 MPH, WHEN I NOTICED THAT MY SPEEDOMETER WAS READING 80 MPH AND ABOVE. BY THE TIME I GOT HOME IT WAS ON 120 MPH AND NOW IT WONT GO BACK DOWN, IT JUST STAYS ON 80 MPH UNTIL I DRIVE IT, THEN IT JUMPS BACK UP AGAIN. *TR

SPEEDOMETER WOULD BE READING A SPEED WHEN I WAS SITTING STILL AND WOULD JUST KEEP INCREASING UNTIL NOW IT SITS WAY PAST 120MPH AND MOVE AT ALL. *TR

FUEL READING IS ALWAYS ON EMPTY EVEN AFTER I FILL UP. I CAN EASILY RUN OUT OF GAS WITH OUT EVEN KNOWING. *TR

SPEEDOMETER IS BROKE MOSTLY ON 0 MILES PER HOUR WHILE DRIVING. I MAY BE OVER SPEED LIMIT WITHOUT KNOWING. *TR

SUDDEN SPEEDOMETER FAILURE. *TR

MY HEADLIGHTS AND DASH LIGHTS FLICKER WHILE DRIVING. ALSO WHILE DRIVING MY LIGHTS WILL DIM AND THE BLOWER FOR HEAT & A/C WILL SLOW AND THEN PICK UP TO NORMAL SPEED AGAIN. 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. I THINK IT IS A SAFETY HAZARD TO HAVE LIGHTS FLICKERING AND ENGINE SURGES. *TR

2005 CHEVY TRAILBLAZER. AFTER ABOUT 45,000 MILES THE FUEL SENSOR NO LONGER OPERATES. *TR

FUEL GAUGE INOPERATIVE. EVEN WITH A FULL TANK, THE GAUGE REMAINS ON EMPTY MOST OF THE TIME. OCCASIONALLY, THE GAUGE WILL RISE TO 1/4 AND STAY THERE FOR 40-50 MILES THEN RETURN TO EMPTY. *TR

SPEEDOMETER SHOWS WRONG SPEED WHILE DRIVING. IT CORRECTS ITSELF AFTER 2-3 DAYS. USUALLY OCCURS WHILE DRIVING ON THE HIGHWAY. *TR

MY SPEEDOMETER IS NOT READING TO CORRECT SPEED ON THE CHEVY TRAILBLAZER FROM 2005. IT IS UP AND DOWN AND WHEN PARKED COULD BE AT ZERO OR 15 MPH...IT IS ALWAYS CHANGING. 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. IT SHOULD BE FIXED BY GM SINCE IT IS A COMMON PROBLEM. I AM TAKING THIS BACK TO THE DEALER TO SEE WHAT THEY CAN DO, BUT I PROBABLY CANNOT AFFORD TO FIX IT ANY TIME SOON. *TR

2005 CHEVY TRAILBLAZER FUEL GAUGE NO LONGER WORKS. WHEN YOU FILL IT UP IT REGISTERS EMPTY AND THE LOW FUEL LIGHT COMES ON. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE DOES NOT WORK AND ALWAYS REGISTERS ZERO. WHENEVER HE FILLS UP THE GAS TANK, THE FUEL GAUGE DIAL DOES NOT MOVE FROM EMPTY TO FULL. THE DIAL REMAINS ON EMPTY AND THE FUEL LIGHT IS CONSTANTLY ILLUMINATED. THE CONTACT FOUND NUMEROUS COMPLAINTS FROM OTHER CONSUMERS WHO EXPERIENCED THE SAME PROBLEM. HOWEVER, THE DEALER HAS NOT BEEN NOTIFIED. THE FAILURE MILEAGE WAS 100,000. UPDATED 01/07/09. *LJ UPDATED 01/08/09. *JB

HEADLIGHTS, DASHLIGHT DIM, BATTERY GAUGE JUMP. THE HEADLIGHTS, DASHLIGHTS AND ALL POWER DIMS OR CUTS OUT WHEN LETTING OFF THE GAS. WHEN IN THE GAS IT WORKS FIN. WHEN I LET OFF EVERYTHING STARTS DIMMING AND CUTTING OUT. AT NIGHT TIME PEOPLE IN FRONT OF ME THINK I'M WANTING THEM TO PULL OVER BECAUSE THE LIGHT FLASH LIKE A POLICE CARS WOULD. I SEE MANY OF THE SAME COMPLAINTS IN MSG BOARDS AND THE DEALERSHIPS KNOW OF THE PROBLEM BUT HAVE NO FIX. THEY TELL YOU TO DEAL WITH IT. I THINK ITS A REAL SAFETY ISSUE AND NEED TO BE ADDRESSES. *TR

2005 TRAILBLAZER LT GAS GAUGE READ EMPTY WHEN SHOULD READ FULL , AND WHEN THE TRUCK IS IN DRIVE THE GAS GAUGE GOES UP THEN GOES BACK DOWN. *TR

I RECENTLY BOUGHT A 2005 CHEVROLET TRAILBLAZER AND SUDDENLY THE SPEEDOMETER BEGAN STICKING, AND NOT WORKING, THEN WORKING AGAIN. UNFORTUNATELY WHEN IT DOES WORK, IT DOES NOT TELL YOU THE CORRECT SPEED THAT YOU ARE TRAVELING AT. THIS IS A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED TO GENERAL MOTORS. IT CONTINUOUSLY WORKS THEN STOP, AND DISPLAYS INACCURATE SPEEDS. LOOKING AT THE COMPLAINTS ON THIS WEBSITE THERE ARE NUMEROUS PEOPLE HAVING THE SAME PROBLEM. *TR

THE HEADLIGHTS, DASH LIGHTS AND DOME LIGHTS ALL FLICKER INTERMITTENTLY. I HAVE HAD THIS PROBLEM SINCE NOV 2004 WHEN I BOUGHT THE TRUCK. RECENTLY I'VE NOTICED THE BATTERY GAUGE FLUCTUATE RATHER WILDLY WHEN THIS PROBLEM IS OCCURRING. IN MY CASE, THERE SEEMS TO BE A CONNECTION TO THE OUTSIDE TEMPERATURE. HOWEVER, GIVEN THE INTERMITTENT NATURE OF THE PROBLEM I CAN'T BE CERTAIN. I HAVE NOTICED THE PROBLEM MORE WHEN THE TEMPS ARE AROUND 35-45F. THE DEALER HAS SEEN THE VEHICLE SEVERAL TIMES FOR THE PROBLEM AND STILL CAN'T DETERMINE THE ISSUE. THE BIG PROBLEM IS THEY HAVEN'T BEEN ABLE TO REPRODUCE THE CONDITION. THE TRUCK NOW HAS 75000 MILES AND IS 4 YEARS OLD. THE FLICKERING/FLASHING HAS GOTTEN MUCH WORSE. ON DEC 2, 2008 THE FLICKERING WAS MORE AKIN TO OUTRIGHT FLASHING. OTHER DRIVERS BEING NOTICEABLY AFFECTED. *TR

WHILE DRIVING AT APPROXIMATELY 30 MPH, MY SPEEDOMETER SUDDENLY WENT TO 90 MPH. I STOPPED AND TURNED THE IGNITION OFF. AFTERWARDS, THE SPEEDOMETER HAS STEADILY INCREASED TO THE POINT WHERE IT BEGINS AT 100 MPH. I HAVE NO IDEA HOW FAST I AM REALLY GOING! I HAVE NOT REPLACED ANY PARTS AS THIS HAPPENED LAST NIGHT. MOREOVER, I UNDERSTAND THE COST OF REPAIR TO BE RATHER EXCESSIVE AT ~$500. *TR

THE GAS GAUGE IS NOT OPERATING. IT STOPPED WORKING WITHOUT ANY WARNING. *TR

INSTRUMENT CLUSTER MALFUNCTIONING. SPEEDOMETER, TACHOMETER AND OIL PRESSURE GAUGES ARE INACCURATE. ALSO HAD TO REPLACE FUEL SENSOR/SENDING UNIT BEFORE VEHICLE REACHED 50,000 MILES. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE WAS NOT WORKING PROPERLY ON THE INSTRUMENT PANEL. HE TOOK THE VEHICLE TO THE DEALER AND THEY STATED THAT THE FUEL SENSOR LOCATED INSIDE THE GAS TANK WAS FAULTY AND NEEDED TO BE REPLACED. THROUGH ONLINE RESEARCH, THE CONTACT DISCOVERED THAT FUEL SENSOR FAILURES FOR THE TRAILBLAZERS WERE VERY COMMON. THE VEHICLE HAS NOT BEEN REPAIRED DUE TO THE TREATMENT THE CONTACT RECEIVED AT THE DEALER. HE FEELS THAT THE INFORMATION ABOUT THE FUEL SENSOR SHOULD HAVE BEEN SHARED BY THE DEALER, RATHER THAN BEING DISCOVERED ON THE INTERNET. HE ALSO FEELS THAT THE VEHICLE IS UNSAFE BECAUSE THERE COULD BE NO FUEL IN THE TANK UNBEKNOWNST TO THE CONTACT. THE CURRENT MILEAGE WAS 57,985 AND FAILURE MILEAGE WAS 52,000.

INSTRUMENT CLUSTER. MY SPEEDOMETER HAS FAILED. MY FUEL GAUGE HAD FAILED A FEW MONTHS AGO. MY DOORS LOCK BY THEMSELVES EVEN WHEN YOU ARE OUT OF THE VEHICLE. A COUPLE OF TIMES AWAY ON A TRIP AND LOCKED OUT OF THE VEHICLE. MY LIGHTS FLICKER AT NIGHT TO ALMOST OFF. CHEVROLET SAID THEY DON'T SEE A PROBLEM HOWEVER IF YOU GET ON LINE YOU ARE ABLE TO CHECK MANY COMPLAINTS ABOUT THE TRAILBLAZER OF THE SAME SITUATION. WHY DOES THE CONSUMER HAVE TO PAY OUT OF POCKET FOR A PRODUCT WITH MANY FAILURES THAT SHOULD NOT HAVE HAPPENED. *TR

ON TWO SEPARATE DAYS, WITHIN A TWO WEEK PERIOD, MY SPEEDOMETER STOPPED WORKING CORRECTLY. THE FIRST TIME IN WENT TO ZERO MPH AND STAYED THERE. A COUPLE OF DAYS LATER IT WORKED AGAIN. THE SECOND TIME, ON THE HIGHWAY, IT READ INCORRECTLY - SAID I WAS AT 55 BUT WAS ACTUALLY GOING 85 (SPOUSE WAS FOLLOWING BEHIND ME IN ANOTHER CAR). *TR

THE SPEEDOMETER ON MY 2005 CHEVROLET TRAILBLAZER WENT HAYWIRE LAST WEEKEND. ON TUESDAY WITH MY WIFE DRIVING OUR 3 MONTH OLD INFANT TO DAYCARE, AND HERSELF TO SCHOOL, THE GAUGE ON THE SPEEDOMETER QUIT COMPLETELY AND CURRENTLY IS POINTING STRAIGHT DOWN AND WILL NOT MOVE REGARDLESS OF THE SPEED THAT I AM TRAVELING. *TR

THE VEHICLE IN QUESTION IS A 2005 CHEVROLET TRAILBLAZER WITH UNDER 40,000 MILES AND VERY WELL-MAINTAINED. THIS IS A CONTINUING CONCERN AND HAVE HAD THE DEALER MECHANICS LOOK AT THIS PROBLEM. WHILE DRIVING AT ANY SPEED, THE LIGHTS WILL DIM DRAMATICALLY WHEN THE ACCELERATOR PEDAL IS RELEASED. THE HEADLIGHTS AND INTERIOR LIGHTS DIM AND RETURN AFTER ACCELERATING FOR ANY LENGTH OR MAGNITUDE AND THEN RETURN TO NORMAL BRIGHTNESS. TYPICALLY, THEY WILL DIM 3 TIMES. I AM CONCERNED ABOUT HOW SEVERE THIS COULD BECOME. THE DEALERSHIP SAID GM ACKNOWLEDGES THIS HAPPENING BUT SAYS IT IS NORMAL AND NO REPAIR IS AVAILABLE. THIS DOES NOT HAPPEN ALL THE TIME BUT DOES HAPPEN 2-3 TIMES A WEEK AND INCONSISTENTLY. I CANNOT IDENTIFY WHAT CAUSES IT OR WHAT CONDITIONS CONSISTENTLY EXIST. HOWEVER, THIS CANNOT BE NORMAL OR SAFE. *TR

THE SPEEDOMETER DOES NOT REGISTER THE CORRECT SPEED ALL THE TIME. I WAS DRIVING DOWN THE HIGHWAY AT 70 MPH AND THE CAR SAID I WAS DOING 110MPH. THE DEALER SAID FILE A COMPLAINT BECAUSE THEY GET THIS PROBLEM A LOT. THERE HAVE BEEN RECALLS ON OTHER GM CARS WITH THE SAME GAUGES AS THE 2005 TRAILBLAZER. SO WHY HAS THERE NOT BEEN A RECALL FOR THE TRAILBLAZER? *TR

BLOWER MOTORS NOT WORKING, REPLACING THE PART, AND FINDING THE WIRING IS MELTED AND SHORTING OUT ON THE HEATER CONTROL MODULE RIGHT SIDE OR REFERRED TO AS THE RESISTOR. THERE HAS BEEN NO RECALL ON THIS PART, BUT WE HAVE FOUND SEVERAL VEHICLES WITH THIS PART HAVE THE SAME ELECTRICAL MALFUNCTIONS WHICH ARE CAUSING OTHER MALFUNCTIONS IN THE VEHICLE. TO REMEDY THE PROBLEM THEY NEED TO UPDATE THE HEATER CONTROL MODULE ON THE RIGHT SIDE OR REFERRED TO AS THE RESISTOR. THIS IS THE PROBLEM. *TR

I PURCHASED MY 2005 CHEVY TRAILBLAZER IN THE SPRING OF 2007. AROUND DECEMBER 2007 MY SPEEDOMETER STARTED HANGING UP. IT IS STILL DOING IT TODAY. THE WORST TIME FOR IT TO HAPPEN IS ON COLD DAYS. I DID NOT HAVE A PROBLEM WITH IT THIS SUMMER. NOW WITH THE FALL OF THE YEAR AND COLDER DAYS, IT HAS BEGUN HANGING UP AGAIN ALMOST EVERYDAY. BECAUSE OF THIS I AM NOT SURE OF MY CORRECT SPEED. I SEARCHED THE INTERNET AND FOUND MULTIPLE COMPLAINTS REGARDING THIS SAME PROBLEM. CHEVROLET HAS ISSUED MANY RECALLS ON OTHER MAKES AND MODEL, BUT HAS YET TO ISSUE A RECALL ON THIS PROBLEM. I FEEL THIS IS A SAFETY ISSUE THAT NEEDS TO BE CORRECTED ON THIS MAKE AND MODEL, AS IT HAS BEEN ON OTHERS. *TR

AFTER DOING SOME RESEARCH I AM ENCOUNTERING A PROBLEM THAT SEEMS TO BE OUT THERE A LOT. I HAVE A 2005 TRAILBLAZER AND MY FORWARD GEAR STOPPED WORKING AT 80K MILES. I THINK IS A MUCH TOO NEW CAR TO ENCOUNTER A TRANSMISSION FAILURE. THERE IS OBVIOUSLY A PROBLEM WHEN I HAVE READ PAGES AND PAGES OF THIS SAME ISSUE. GM HAS TO STEP IN AND TELL ME SOMETHING MY DEALER ESTIMATE THIS TO COST ME A MIN. $3,200.00 IN THIS ECONOMY OR ANY THAT IS A LARGE EXPENSE TO ENCOUNTER WITH NO WARNING OR PREVIOUS PROBLEMS. I HOPE THE GM WILL HAVE SOME ANSWERS AND DO THE RIGHT THING! THIS HAPPENED TO ME ON THE VAN WYKE EXPRESSWAY IN RUSH HOUR MANY OF US COULD HAVE BEEN HURT OR KILLED! THANK YOU *TR

SPEEDOMETER WORKED FINE THEN STARTED GOING IN AND OUT, NOW COMPLETELY STOPPED WORKING, SPOKE WITH SEVERAL OTHER TRAILBLAZER OWNERS SAME PROBLEM, SPOKE WITH A WORKER AT GM STATED SEVERAL VEHICLES HAVE BEEN REPAIRED FOR PROBLEM. *TR

MY VEHICLE HEADLIGHTS IN MY 2005 CHEVROLET TRAILBLAZER, BLINK, FLICKER OR FLASH WHEN TOO MUCH POWER IS GOING IN, I DON'T THINK THIS VEHICLE HAS A BIG ENOUGH ALTERNATOR, BUT THE DEALER OR GM WILL NOT DO ANYTHING TO HELP ME, THEY SAID ITS NORMAL. IF ITS NORMAL THAT THE HEADLIGHTS FLICKER, I WOULD HAVE NEVER BOUGHT THIS VEHICLE. IT IS JUST SO FRUSTRATING TO HAVE A VEHICLE IN A SHOP WHEN YOU NEED IT FOR DAY TO DAY LIVING. THIS HAS BEEN GOING ON FOR 8 MONTHS NOW. THIS COULD KILL SOMEONE AND ACCORDING TO MULTIPLE BLOG SITES THIS IS A PROBLEM FOR A LOT OF PEOPLE. *TR

WHEN DRIVING AT NIGHT TYPICALLY WHILE "COASTING" BETWEEN 30-50 MPH MY HEADLIGHTS ON MY TRAILBLAZER DIM, THE BATTERY CHARGE GOES DOWN, AND THE BLOWER STOPS WORKING FOR JUST A SECOND. AFTER RESEARCHING THIS ON THE INTERNET I HAVE NOTICED THAT MANY OTHER PEOPLE ARE HAVING A SIMILAR, AND UNRESOLVED PROBLEM WITH THEIR TRAILBLAZERS AS WELL. THIS IS DANGEROUS BECAUSE HEADLIGHTS ARE NECESSARY, ALSO SOMETHING THAT SHOULD NOT BE A CONSISTENCY WITH MANY CONSUMERS. MINE IS A 2005 CHEVROLET TRAILBLAZER LS. I HOPE IS MATTER IS LOOKED INTO MORE SINCE THERE IS A HUGE PROBLEM THAT MANY CUSTOMERS ARE HAVING THAT IS GETTING IGNORED. WE NEED SOMEONE TO LOOK OUT FOR US! *TR

GAS GAUGE DOESN'T READ CORRECTLY. WHEN I FILL UP THE GAS GAUGE IT WILL STAY ON EMPTY AND THE LIGHT WILL STAY ON. AFTER DRIVING FOR A DAY OR SO THE GAS GAUGE WILL FLUCTUATE FROM EMPTY TO FULL NUMEROUS TIMES. I KEEP TRACK OF MY MILES TO KNOW WHEN TO FILL UP AND NEVER KNOW HOW MUCH GAS I HAVE. THERE ARE NUMEROUS COMPLAINTS SIMILAR TO MY PROBLEM. GO TO HTTP://WWW.TOPIX.COM/FORUM/AUTOS/CHEVROLET-TRAILBLAZER/TH8JI6TEPO3VRJI3D/P2. I ONLY READ 20 COMPLAINTS AND OF COURSE THERE ARE MANY MORE TO READ. PLEASE HAVE THIS PROBLEM KNOWN AND FIXED SINCE IT ISN'T UNDER RECALL. *TR
