2004 CHEVROLET TRAILBLAZER EXT 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

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

AT 40,000 MILES MY CHEVY TRAILBLAZER'S SPEEDOMETER STOPPED WORKING- AT 120 MPH AND HAS BEEN STUCK THERE FOR A WEEK. *JB

ONCE IN A WHILE WHILE DRIVING DOWN THE RAOD THE REAR HATCH WINDOW POPS OPEN. THIS DOES NOT HAPPEN ALL THE TIME BUT IN THE PAST YEAR IT HAS HAPPEN FOUR TIMES. TWICE IN THE PAST MONTH. *JB

DT*: THE CONTACT STATED WHILE AT A STOP, THE STEERING WHEEL WAS ADJUSTED, BUT WOULD NOT LOCK IN POSITION. THE VEHICLE WAS TAKEN TO THE SALES/SERVICE DEALER. ON INSPECTION, THE CONTACT WAS INFORMED THAT THE TILT RACK WOULD NOT LOCK AND THE STEERING COLUMN NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED.

2004 CHEVY TRAILBLAZER. INTERMITTENT ENGINE STALLING SINCE NEW. MANY SERVICE VISITS TO CHEVY DEALERS TO FIX, HOWEVER MECHANICS STUMPED. LOCAL GAS STATION MECHANIC FOUND THE PROBLEM HAVING TO DO WITH COMPONENTS IN THE EMISSION CONTROL / VAPOR RECOVERY SYSTEM. NOW CHEVY NEEDS TO FIGURE OUT THE CURE. IN THE MEANTIME I GET TO DRIVE AROUND WITH THE "CHECK ENGINE" LIGHT ON. I GUESS THIS IS BETTER THAN BEING CRASHED BECAUSE MY CAR STALLED IN AN INTERSECTION OR ON THE HIGHWAY. CHEVY MECHANICS AND ENGINEERS NEED TO GET THE "DUH" AWARD. VERY BAD CUSTOMER SERVICE AND DIAGNOSTICS PERFORMED BY CHEVY. I WOULD STILL LIKE TO HAVE THE CHECK ENGINE LIGHT TO GO OFF, AND HAVE THE ENGINE NOT STALL IF THAT IS POSSIBLE. PLEASE SEND INFO TO HAVE THIS DONE IF POSSIBLE. *JB

I AM COMPLAINING ABOUT A 2004 CHEVY TRAILBLAZER PROBLEM THE SPEEDOMETER IS MEASURING INCORRECT SPEED OR NOT WORKING AT ALL. I CAN BE PARKED AND IT READS 60 MPH I AM DRIVING IT READS 120 MPH. IN SPEAKING WITH SEVERAL GM OWNERS THIS IS A PROBLEM WITH QUITE A FEW GM VEHICLES AND IS VERY DANGEROUS. I THINK THIS SHOULD BE LOOKED INTO BEFORE SOMEONE GETS HURT. IT IS VERY SCARY NOT TO KNOW WHAT SPEED YOU ARE DRIVING AT. IN SPEAKING TO SEVERAL OWNERS AND LOOKING AT WEB SITES OF COMPLAINTS THIS IS A PROBLEM AND HAS BEEN ONE FOR A LONG TIME. I DO NOT BLAME MY DEALER I BLAME CHEVROLET OR GM WHOEVER MADE THE CAR THERE ARE SO MANY COMPLAINTS ABOUT THIS SPEEDOMETER WITH OTHER MAKES FROM GM, ITS NOT THE DEALERS FAULT FOR THIS PROBLEM. *NM

WENCH HOLDING SPARE TIRE ON 2002 CHEVY TRAILBLAZER WAS STUCK AND WOULD NOT LOWER THE TIRE. HAVING A FLAT TIRE IS BAD ENOUGH BUT BEING TOLD THAT THEY WOULD HAVE TO CUT AND DESTROY THE WENCH MECHANISM IN ORDER GET THE SPARE TO PUT IT ON IN PLACE OF THE FLAT ONE WAS NOT GOOD NEWS. I TOLD AAA TO PROCEED AND CUT THE CABLE AND MECHANISM SO THEY COULD CHANGE MY FLAT TIRE. I FOUND THIS IS NOT UNDER WARRANTY AND IT COST $137.00 TO REPLACE THE WENCH. THIS HAPPENED IN AUGUST 2006/ IN OCTOBER, MY WIFE HAD A FLAT AND GUESS WHAT THE WENCH WOULD NOT LOWER THE SPARE AND AGAIN THE MECHANISM HAD TO BE REPLACED. I PUT MY SPARE ON MY WIFE'S 2004 CHEVY TRAILBLAZER SO SHE COULD CONTINUE HER TRIP TO IOWA. HER WENCH WAS REPLACED AT A COST $143.00. OBVIOUSLY THIS IS A PROBLEM WITH CHEVY TRAILBLAZERS AS IT HAPPENED WITH MY 2002 AND MY WIFE'S 2004. THERE IS NEVER A MENTION IN THE OWNER'S MANUAL ABOUT ANY MAINTENANCE ON THE WENCH. TO FIND THE PROBLEM WHEN YOU HAVE A FLAT IS NOT THE RIGHT TIME TOM DISCOVER THE WENCH DOESN'T WORK. I FILED A COMPLAINT WITH GENERAL MOTORS ON MONDAY OF THIS WEEK AND WAS TOLD THAT ALL COMPLAINTS ARE REVIEWED BY SUPERVISORS. I SIMPLY REPLIED THAT IT WAS HIGHLY UNLIKELY THAT I WOULD EVER HEAR FROM ANYONE AT GM ABOUT THIS PROBLEM. *NM
