2004 CHEVROLET TRAILBLAZER Complaints

THE INSTRUMENT PANEL DOESN'T WORK. THE SPEEDOMETER WORKS WHEN IT WANTS TO. IT WILL READ THAT I'M GOING 120 MPH WHEN I'M NOT, CURRENTLY IT'S STUCK ALL THE WAY UP! *TR

THE SPEEDOMETER IN MY 2004 CHEVY TRAILBLAZER EXT COMPLETELY STOPPED WORKING ABOUT 6 MONTHS ABOUT. WE HAVE BEEN DEALING WITH THIS ISSUE AND JUST PRAYING WE DO NOT GET A SPEEDING TICKET. NOW THE CHECK ENGINE LIGHT CONTINUES TO STAY ON EVEN WHEN RESET. I AM NOT BEING TOLD I NEED TO CHECK THE FUSE WHICH WAS UNSUCCESSFUL. I CAN ONLY IMAGINE IF THE NEXT THING TO GO WILL BE ALL THE ELECTRONICS IN THE DASHBOARD. THIS SERIOUSLY NEEDS TO BE A RECALL ITEM! *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE GAUGES ON THE INSTRUMENT PANEL STOPPED WORKING INTERMITTENTLY. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS SENT AND EMAIL BUT DID NOT RESPOND. THE FAILURE MILEAGE WAS 86,000.

THE TACH AND SPEEDOMETER DOES NOT FUNCTION PROPERLY ON MY 2004 TRAILBLAZER. THE SPEEDOMETER OCCASIONALLY WORKS BUT 99% OF THE TIME TELLS ME I'M GOING FASTER OR SLOWER THAN I AM. I AM CURRENTLY USING MY GPS, BUT AS WE ALL KNOW WITH GPS, IT'S NOT ALWAYS AVAILABLE ON MOUTAINS AND IT'S NOT ALWAYS 100% ACCURATE SO I BASICALLY GUESS HOW FAST I AM GOING WHEN TRAVELING THROUGH WV. I CONTACTED GM DEALER, NO RECALLS THAT I AM AWARE OF BUT THOUSANDS OF ONLINE POST OF THIS PROBLEM. *LN

ON 1/23/2011 I WAS ON A TRIP, 77 MILES FROM HOME, WHEN MY 2004 CHEVY TRAILBLAZER'S INSTRUMENT PANEL WENT CRAZY. I THOUGHT MY ENGINE WOULD BLOW BECAUSE THE RPM GAUGE WENT OFF THE CHARTS, THEN WOULDN'T READ ANYTHING. THEN MY SPEEDOMETER DID THE SAME. I HAD NO IDEA HOW FAST I WAS GOING, ON THE INTERSTATE. I WAS WORRIED, SO I MOVED TO THE LEFT LANE, AND STAYED BEHIND THE SLOWER TRAFFIC TO BE SAFE. WHEN I GOT HOME, I STOPPED AT MY LOCAL CHEVY DEALERSHIP WHERE I WAS TOLD THAT ALMOST EVERY TRAILBLAZER OVER 80,000 MILES IS HAVING THE SAME ISSUES. THE PROBLEM COULD BE MY INSTRUMENT PANEL COMPUTER, OR ONE OF SEVERAL BAD MODULES. THE CAN DOES NOT SHOW ANY ERROR CODE, SO THE COST TO REPAIR RANGES FROM $600 TO OVER $1500 DEPENDING ON HOW LONG IT TAKES YOUR REPAIR PERSON TO FIND THE PROBLEM. AFTER MY DIAGNOSIS I WAS ANGRY, I AM TIRED OF REPAIRING ITEMS ON THIS CAR. I WENT ONLINE TO SEE IF IT WAS RARE, OR IF ANYONE ELSE HAD THE PROBLEM, AND AN EXACT REPAIR. ON ONE WEBSITE ALONE ABOUTAUTOMOBILE.COM I FOUND OVER 1,300 TRAILBLAZER OWNERS WITH THE SAME PROBLEM. AFTER FURTHER RESEARCH I HAVE FOUND ALMOST 19,000 TRAILBLAZER COMPLAINTS ABOUT THE SAME PROBLEM. I DO BELIEVE THAT ALL TRAILBLAZERS WILL HAVE THIS ISSUE, AND THAT GM SHOULD FIX IT, WITH A RECALL REPAIR. I HAVE SENT COMPLAINTS TO GM, BUT NO RESPONSE HAS BEEN GIVEN. *TR

MY SPEEDOMETER FAILED AND READS ANYTHING IT WANTS. YOU CAN BE DOING 25MPH AND IT WILL READ 110MPH OR YOU CAN BE DOING 60MPH AND IT WILL REGISTER 45MPH. THERE ARE A MILLION COMPLAINTS ON THE INTERNET ABOUT GM SPEEDOMETERS AND OTHER INSTRUMENT CLUSTERS FAILING. I THINK THIS IS A SAFETY CONCERN AND SHOULD BE INVESTIGATED. GM IS JUST PASSING THE BUCK WHEN YOU ASK FOR HELP. JUST GO TO GOOGLE AND ASK FOR GM INSTRUMENT CLUSTER FAILURE AND COUNT THE COMPLAINTS. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

INSTRUMENT PANEL MALFUNCTIONS. SPEEDOMETER AND TACHOMETER DISPLAY INACCURATE INFORMATION. SPEEDOMETER WILL REGISTER 60 MPH WHILE AT A RED LIGHT. TACHOMETER DOES NOT GO TO ZERO EVEN WHEN ENGINE IS OFF. *TR

I HAVE SEEN ACROSS MANY WEBSITES THAT THE INSTRUMENT PANEL ON THE 2004 CHEVROLET TRAILBLAZERS MALFUNCTION. WELL, OUR VEHICLE IS HAVING THE SAME ISSUE. MY MECHANIC SAYS HE HAS SEEN SEVERAL SIMILAR PROBLEMS AND SAYS IT WILL COST ABOUT $600 TO REPAIR. HE SUGGESTED CONTACTING CHEVY, BUT I HAVE SEEN THAT CHEVY IS NOT INTERESTED IN RESOLVING THE PROBLEM. I FIGURED IF THEY ARE GETTING ENOUGH COMPLAINTS TO THE NTSB, MAYBE THEY WILL RECALL THE EQUIPMENT AND I CAN GET IT PROPERLY REPAIRED. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 70 MPH THE INSTRUMENT PANEL STOPPED FUNCTIONING. THE SPEEDOMETER DID NOT DISPLAY THE SPEED THAT THE VEHICLE WAS TRAVELING. THE FUEL GAUGE ALSO DID NOT DISPLAY THE CORRECT AMOUNT OF FUEL IN THE VEHICLE. THE VEHICLE WAS NOT TAKEN TO THE DEALER TO BE REPAIRED. THE DEALER STATED THAT THE CONTACT HAD TO PAY THE REPAIR COSTS. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

GM IS HAVING AN ELECTRICAL ISSUE ON MANY 2004 VEHICLES RESULTING IN GRADUAL DETERIORATION OF INSTRUMENT CLUSTER PERFORMANCE. IT STARTS WITH THE SPEEDOMETER FAILING, READING 120 MPH WHILE SITTING AT A RED LIGHT. THEN THE FUEL GAUGE, LOW FUEL LIGHT WILL COME ON, THEN WHILE DRIVING TO A FUEL STATION IT WILL SLOWLY CLIMB TO 1/2 TANK READING OR MORE. NEXT IS THE TACHOMETER, IT WILL BOUNCE FROM 2000 RPM TO OVER 6000 RPM (RED LINE) ALSO WHILE SITTING AT STOP SIGN OR PARKED IN A PARKING SPACE. FINALLY THE OIL AND COOLANT TEMPERATURE GAUGES READ HOT (PAST RED LINE) AT INITIAL START UP FROM SITTING 12 HOURS IN -3 DEGREE WEATHER. AN ONLINE SEARCH HAS FOUND NUMEROUS COMPLAINTS OF THE SAME PROBLEM AROUND THE UNITED STATES EXTENDING BEYOND THE TRAILBLAZER TO OTHER VEHICLES. THIS SAME ISSUE WAS RECALLED ON GM TRUCKS BUT THE OTHER VEHICLES. THE VEHICLE OPERATOR HAS NO ACCURATE IDEA OF MPH, RPM, OIL OR WATER TEMPERATURE AND BATTERY CHARGE. THE AVERAGE REPAIR COST TO REPLACE THE BAD COMPUTER BOARD IS $500 TO $1000. *TR
