2005 Chevrolet Trailblazer

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 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

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

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

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

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

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
