2004 CHEVROLET TRAILBLAZER Complaints

SPEEDOMETER FAILS TO REPORT THE PROPER SPEED,AT TIMES IT STARTS OUT AT 80 MPH AND GO UP TO 120 MPH SITTING STILL, AT TIMES THE WHOLE INSTRUMENTS PANEL FAILS ( FUEL GAUGE TEMP GAUGE VOLTAGE METER ). *TR

WE HAVE A 2004 TRAILBLAZER LT AND HAVE ISSUES WITH THE SPEEDOMETER NOT WORKING PROPERLY. IT GETS STUCK BETWEEN 30-120MPH OR DOES NOT MOVE AT ALL. TOOK IT TO A CHEVY DEALER A FEW MILES FROM OUR HOME. THEY SAID, THEY HAVE TO SEND THE INSTRUMENT CLUSTER OUT TO GET REPAIRED/ REPROGRAMMED AND IT WOULD COST $525. I DON'T UNDERSTAND WHY CHEVY DOES NOT PROVIDED SOME SORT OF DISCOUNT OR RECALL FOR THE REPAIRS SINCE IT SEEMS TO BE A VERY COMMON ISSUE WITH THERE TRAILBLAZERS. *TR

SPEEDOMETER AND FUEL GAGE COMPLETELY STOPPED WORKING. RESEARCHED THE INTERNET AND LOTS OF PEOPLE HAVE COMPLAINED OF THIS VERY ISSUE, BUT NO RECALL HAS BEEN MADE. THIS IS A SAFETY HAZARD AND TO FIX THIS PROBLEM OUR DEALERSHIP SAID IT WOULD COST ANYWHERE AT THE LEAST $500. THIS REALLY UPSETS ME AS WE CANNOT AFFORD TO FIX THIS FOR THAT AMOUNT OF MONEY. *TR

REAR WINDOW EXPLODED AFTER REAR DEFOGGER WAS TURNED ON . APPROX 5 MIN. IN USE. *TR

I STARTED TO LOSE THE HIGH SPEEDS ON THE FAN BLOWER. IN CHECKING THE INTERNET I FOUND THIS IS A COMMON PROBLEM FOR G.M. THE PROBLEM IS THE BLOWER MOTOR RESISTOR. WHEN I WENT TO REPLACE THIS PART I FOUND THAT THE WHOLE WIRING HARNESS HAD BEEN BURNT TO. IT GOT SO HOT THAT IT MELTED EVERYTHING. THE FUSE FOR THIS DID NOT EVEN BLOW. THIS COULD HAVE SET THE TRUCK ON FIRE. IT IS FUNNY HOW THE PARTS TO FIX THIS HAS MUCH THICKER WIRE. THE PARTS IN TOTAL WAS AROUND $118. THANKS TO A FRIEND I HAD NO LABOR COST. IF I WOULD OF TAKEN IT TO A G.M. DEALER FOR SURE THEY WOULD OF WANTED OVER $300. G.M. KNOWS THEY HAVE A PROBLEM AND ARE DOING NOTHING ABOUT IT. I FEEL THIS IS A SERIOUS MATTER AS IT COULD OF SET THE TRUCK ON FIRE. *TR

THE INTERIOR VENTS STOPPED WORKING AND WOULD ONLY GO TO 3 MAX ON THE DIAL. THAT WAS 1000 DOLLARS TO REPAIR. THE RPM GAUGE WENT OUT NEXT, NOW THE SPEEDOMETER STOPPED WORKING AND THE BATTERY DOESN'T HOLD A CHARGE. I HAVE HAD THIS CAR FOR TWO YEARS AND IT IS BEGINNING TO COST A LOT FOR REPAIRS. I HAD TO BUY A BATTERY AND AM REPAIRING THE GAUGES AT $600. THESE ARE ALL NEW PARTS. I FEEL AT THIS POINT SOMEONE NEEDS TO LOOK INTO THIS COMPLAINT. MOST PEOPLE AREN'T REPAIRING THE SPEEDOMETER BECAUSE IT IS SO COSTLY, BUT I THINK THIS IS A HAZARD. CHECK OUT THIS WEBSITE FOR MORE COMPLAINTS: HTTP://WWW.CARCOMPLAINTS.COM/CHEVROLET/TRAILBLAZER/2004/ELECTRICAL/GAUGES_FLUCTUATE.SHTML WE ARE ALL HAVING THE SAME PROBLEMS AND NO ONE IS DOING ANYTHING ABOUT IT. *TR

A SMALL CRACK OR FRACTURE HAS DEVELOPED IN THE FUEL TANK FILLER NECK. THIS WILL CAUSE THE CHECK ENGINE LIGHT TO COME ON AND MAY CAUSE THE TB TO IDLE POORLY WHEN COLD. THERE IS A SMELL OF GASOLINE. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE INSTRUMENT PANEL HAS NOT WORKED SINCE SHE PURCHASED THE VEHICLE BRAND NEW IN JANUARY OF 2004. THE WARNING INDICATORS ARE CONSTANTLY ILLUMINATED. SHE TOOK THE VEHICLE TO THE DEALER SEVERAL TIMES WHILE IT WAS UNDER WARRANTY, BUT THEY COULD NOT LOCATE THE FAILURE. DUE TO THE FAILURE, SHE DOES NOT KNOW HOW FAST SHE IS DRIVING, HOW MUCH FUEL IS IN THE VEHICLE, AND CANNOT READ THE ODOMETER. RECENTLY, THE HEADLIGHTS FAILED AND SHE TOOK THE VEHICLE BACK TO THE DEALER. THE DEALER CHARGED $91 TO DIAGNOSE THE FAILURE, WHICH PRODUCED A FAILURE CODE AT THE HEADLIGHT LOW BEAM RELAY CLUSTER SWITCH. THE DEALER REPLACED THE LOW BEAM RELAY SWITCH AND IGNITION SWITCH, BUT THE FAILURE PERSISTED. NOW THAT THE VEHICLE IS OUT OF WARRANTY, THE DEALER HAS FINALLY LOCATED A DIAGNOSTIC CODE FOR THE INSTRUMENT PANEL FAILURE. THE DEALER STATED THAT THE INSTRUMENT PANEL CLUSTER FAILED AND WOULD COST $600 TO REPAIR. THE FAILURE MILEAGE WAS 9,000 AND CURRENT MILEAGE WAS 68,000. UPDATED 4/14/09 *CN THE AIR BAG LIGHT ILLUMINATED. UPDATED 04/17/09. *JB

I HAVE MANY ELECTRICAL ISSUES WITH MY 04 TRAILBLAZER FROM MY WINDOW LIGHTS ON THE DRIVERS DOOR AND THE PASSENGER DOOR. I HAVE HAD MY RADIO REPLACED BECAUSE IT MELTED ONE OF MY CDS. MY HEAD LIGHTS WORK WHEN THEY FEEL LIKE IT SAME WITH THE REAR WIPER. IT HAS STALLED OUT IN TRAFFIC ON ME. I HAVE ALSO HEARD THAT IN MOST 2000 TO 2006 TRAILBLAZERS THE REASON FOR THE ELECTRICAL PROBLEMS IS BECAUSE WATER IS RUNNING DOWN THE PASSENGER SIDE DOOR INTO THE DASH AND HITTING ONE OF THE MAIN WIRING HARNESSES CAUSING IT TO HAVE MANY ELECTRICAL ISSUES. I HEARD THIS FROM SOMEONE WHO HAS AN 06 TRAILBLAZER THAT JUST HAD IT A REPLACED FOR $700.00 TO FIX AND WAS TOLD THAT IT WILL JUST HAVE TO BE REPLACED IN A FEW MORE YEARS BECAUSE THEY CANT FIX THE PROBLEM. *TR

MY 2004 CHEVY TRAILBLAZER WAS PARKED IN MY DRIVEWAY AND THE REAR WINDOW SUDDENLY SHATTERED. THERE WAS NO BREAK IN NOR ANYONE NEAR THE VEHICLE. *TR
