2004 CHEVROLET TRAILBLAZER Complaints

I HAVE A 2004 TRAILBLAZER EXT AND A 2004 CREW CAB SILVERADO. BOTH OF MY SPEEDOMETER ARE STICKING ON BOTH VEHICLES. I HAVE NOT TAKING TO THE DEALERSHIP BUT FROM MY RESEARCH ON THE WEB IT LOOKS LIKE IT IS GOING TO COST ME A LOT OF MONEY. *JB

MY 2004 CHEVY TRAILBLAZERS SPEEDOMETER STARTED MALFUNCTIONING. IT WILL REGISTER SPEEDS 25-35 MILES PER HOUR OVER ACTUAL. IT ALSO DOES NOT OPERATE SMOOTHLY BUT JERKS TO THE NEXT NUMBER. VERY DANGEROUS, AND VERY EXPENSIVE TO FIX. IT APPEARS THAT THIS IS ALSO HAPPENING ON THE ENVOY, TAHOE AND AVALANCHE MODELS. THIS SHOULD BE QUALIFIED AS A SAFETY RECALL. *JB

VEHICLE SWITCHING INTO 4WD/AWD ON ITS OWN - MALFUNCTION TOOK VEHICLE IN BECAUSE VEHICLE WAS TRYING TO SWITCH INTO AWD AND 4WD ON ITS OWN AT FREEWAY SPEEDS. WHEN THIS HAPPENS, ENTIRE VEHICLE JERKS WHEN SWITCHING (ON ITS OWN) FROM 2HI TO AWD. CHEVY SERVICE DEPARTMENT FOUND PROBLEM IN TRANSFER CASE MODULE. THEY REPLACED MODULE AND PROGRAM. VEHICLE 4WD MALFUNCTIONED AGAIN. VEHICLE TRYING TO SWITCH INTO 4WD AND AWD ON ITS OWN. TOOK VEHICLE BACK TO SERVICE DEPARTMENT. SERVICE DEPARTMENT REPLACED ENCODER MOTOR. VEHICLE IS STILL SWITCHING INTO 4WD AND AWD RANDOMLY. I WILL TAKE IT IN AGAIN. THESE PROBLEMS STARTED WHILE STILL UNDER WARRANTY. I HAVE UNDER 43000 MILES ON VEHICLE AT THIS TIME. INTERNET SEARCH SHOWS MANY TRAILBLAZER OWNERS WITH THIS SAME PROBLEM. *JB

THIS IS THE SECOND COMPLAINT I AM SUBMITTING ABOUT THE SPEEDOMETER ON MY CHEVY TRAILBLAZER. I JUST WANTED TO INCLUDE SOME LINKS TO CUSTOMER DISCUSSION FORUMS, IN WHICH YOU CAN SEE THAT THIS SPEEDOMETER IS A BIG PROBLEM. GM TRIES TO IGNORE THE PROBLEM AND MOST CUSTOMERS HAVE NO OUTLET TO VENT THEIR PROBLEMS, OUTSIDE OF THE DEALERSHIP WHO IS TRYING TO HIDE THE PROBLEM. PLEASE TAKE A LOOK AT SOME OF THESE DISCUSSIONS AND YOU WILL SEE HOW GM IS IGNORING THIS VERY SERIOUS PROBLEM.

AT APPROXIMATELY 36,000 MILES THE SPEEDOMETER ON MY CHEVY TRAILBLAZER STARTED ACTING FUNNY. AT APPROXIMATELY 40,000 MILES IT STARTED TO GET STUCK. AT 45,000 MILES IT STOPPED WORKING ALTOGETHER. IT IS NOW STUCK IN THE DOWN POSITION POINTING TOWARD THE INSTRUMENT PANEL. I HAVE SPOKEN TO NUMEROUS CHEVY TRAILBLAZER OWNERS AND HAVE VISITED A NUMBER OF ONLINE DISCUSSION GROUPS AND HAVE FOUND OUT THAT A NUMBER OF PEOPLE HAVE HAD THIS SAME PROBLEM. THIS IS A VERY SERIOUS SAFETY ISSUE, WHICH CAN LEAD TO INJURY OR DEATH. *NM

REAR HATCH WINDOW POPS OPEN WHILE DRIVING. THIS HAS HAPPEN FOUR TIME THIS WEEK ALONE. *NM

TL*- THE CONTACT OWNS A 2004 CHEVROLET TRAIL BLAZER EXT WITH AN ODOMETER READING OF 40,000 MILES. THE FAILURE MILEAGE WAS 36,000. THE FIRST INCIDENT INVOLVED LEAK IN A FUEL HOSE AND THE SECOND WAS A CRACK IN THE FUEL TANK. THE DEALER ADVISED THE CONTACT TO CALL AND COMPLAIN TO NHTSA SINCE THE 2004 ARE NOT UNDER THE RECALL, AND THE 2002 ARE UNDER RECALL FOR THE SAME ISSUE. THE DEALER HAD TEMPORARILY REPAIRED THE VEHICLE. THE CONTACT SMELLS FUMES WHILE DRIVING. THE FUMES ARE DETECTABLE WHILE DRIVING AT ANY SPEED. THE CONTACT DID NOT HIT ANYTHING TO CAUSE THE DAMAGE. THE CONTACT HAS REPAIR INVOICES AND PICTURES.

ODOMETER FAILURE AFTER 81,000 MILES... ODOMETER WILL LOCK ON DIFFERENT SPEEDS, FROM 10-40- 110 MPH EVEN THOUGH I AM NOT TRAVELING THAT SPEED. MY MECHANIC SAYS THAT THIS PART NEEDS TO BE RECALLED BECAUSE HE HAS HAD TO REPLACE SO MANY CHEVROLET TAHOE AND TRAILBLAZERS WITH THE SAME PROBLEM. THIS PART CAN RUN OVER $300.00 SOMETIMES. *JB

WE BOUGHT A 2004 CHEVY TRAILBLAZER BRAND NEW. WE HAD ALL SCHEDULED MAINTENANCE PERFORMED. THEN IN DECEMBER 29TH OF 2006 IN THE EVENING WE EXPERIENCED A LOSS OF THE TRANSMISSION IN THIRD GEAR. WE WERE TRYING TO MERGE ONTO A HIGHWAY AND WERE ALMOST REAR ENDED BY A SEMI-TRACTOR TRAILER TRUCK. I QUICKLY PULLED OFF TO THE BREAK DOWN LANE TO AVERT AN ACCIDENT. IT HAS BEEN ROUGHLY BEEN SIX WEEKS SINCE WE DROPPED THE VEHICLE OFF AT A AUTHORIZED CHEVY DEALER. OUR EXTENDED WARRANTY WANTS TO REBUILD THE TRANSMISSION. THE CHEVY SERVICE DEPARTMENT WANTS TO REPLACE IT. THEY ARE AT A STALEMATE. THIS VEHICLE HAD ONLY 68000 MILES ON IT. *JB

SPEEDOMETER SUDDENLY STARTED READING RANDOMLY, USUALLY 10-15 MPH TOO HIGH. INTERMITTENT. *JB
