2005 CHEVROLET TRAILBLAZER Complaints

MY WIFE WAS DRIVING OUR VEHICLE WITH OUR TWO CHILDREN IN THE CAR. SHE WAS TRAVELING AT HIGHWAY SPEED WITH THE CRUISE CONTROL SET WHEN THE SPEEDOMETER OF OUR VEHICLE FAULTED. IT STARTED SHOWING SHE WAS GOING 110 THEN 20MPH THEN 50MPH AND SO ON AND SO ON. SHE PULLED OVER, PHONED ME AND WE CALLED OUR INSURANCE COMPANY TO SEE IF TOWING COULD BE PROVIDED. IT WOULD HAVE TAKEN OVER 2HRS FOR TOWING ASSISTANCE SO SHE TRAVELED THE REST OF THE TRIP (APPROX 105MILES) FOLLOWING ANOTHER VEHICLE IN HOPES THAT THEY WERE TRAVELING AT A SAFE SPEED. THE FOLLOWING DAY I RESEARCH THIS ISSUE, BROUGTH MY VEHICLE TO A DEALERSHIP AND THEY EXPLAINED IT WAS A KNOWN ISSUE WITH A 05 TRAILBLAZER AND THE GM HAD A CLASS ACTION LAW SUIT FOR REPLACEMENT OF THIS PART THEY STATE THE INSTRUMENT PANEL NEEDED TO BE REPLACED. HOWEVER, WE LATER FOUND OUT THAT OUR VEHICLE WAS NOT PART OF THIS LITIGATION AND WE WERE STUCK PAYING THE BILL. NOT ONLY DOES GM KNOW THIS IS A SAFETY ISSUE, THEY ARE UNWILLING TO COMPENSATE OR TAKE CORRECTIVE ACTION FOR THEIR CUSTOMERS. NEEDLESS TO SAY I AM VERY UPSET AND FRUSTRATED FOR THE SAFETY OF MY FAMILY AND THE FACT THE GM HAS NOT OFFERED ANY REMORSE. *TR

MY RPM GAUGES STARTED MESSING UP NEED MY SPEEDOMETER STARTED NEXT. THEY STARTED STICKING AND JUMPING UP. MY 2005 TRAILBLAZER ONLY HAS 47,000 MILES ON IT AND THE CHECK ENGINE LIGHT STAYS ON ALL THE TIME. HAS BEEN SERVICED REGULARLY SO I REALLY DON'T KNOW WHAT IT GOING ON WITH IT!

OUR 2005 TRAILBLAZER IS HAVING THE SAME ISSUE AS EVERY COMPLAINT I HAVE READ ON THIS SITE. THE FUEL GAUGE IS NOT WORKING AND THE SPEEDOMETER STICKS AFTER DRIVING FOR ABOUT 20 MINUTES. I READ THAT THERE HAS BEEN A PETITION INVOLVING THIS PARTICULAR PROBLEM. I WILL BE GETTING MORE INVOLVED WITH THIS. I WILL BE ALSO CALLING. *TR

MISLEADING INFORMATION ON THE SPEEDOMETER OF THE TRAILBLAZER. THE HAS STOPPED REGISTERING THE CORRECT SPEED DURING TRAVEL. WHILE STOPPED AT A RED LIGHT THE SPEEDOMETER WAS READING 20 MPH. THIS CAN BE DANGEROUS FOR DRIVERS BECAUSE THEY DO NOT KNOW WHAT SPEED THEY ARE CURRENTLY TRAVELING. WHILE TRAVELING AT 45 MPH THE SPEEDOMETER WAS READING 75 MPH.

I HAVE A 2005 CHEVROLET TRAILBLAZER AND IN THE SUMMER OF 2010 I FILLED MY CAR UP WITH GAS AND THE GAS GAUGE NEEDLE WENT OVER TO EMPTY. THE NEEDLE WOULD FLUCTUATE BACK AND FORTH FROM EMPTY TO FULL SO I DIDN'T KNOW HOW MUCH GAS I REALLY HAD. I CALLED THE DEALERSHIP SERVICE DEPARTMENT AND THEY KNEW EXACTLY WHAT I WAS TALKING ABOUT. THEY SAID THE FUEL SENSOR IS DEFECTIVE AND IT WOULD COST ABOUT $1000 TO REPAIR. I DID SOME RESEARCH ONLINE AND THIS IS A VERY COMMON PROBLEM WITH MOST TRAILBLAZERS. I BELIEVE THERE NEEDS TO BE A RECALL BECAUSE YOU CAN'T TELL IF YOU ARE ABOUT TO RUN OUT OF GAS OR NOT. *TR

FAULTY FUEL GAUGE SENDING UNIT. VERY COMMON PROBLEM IN MANY CHEVROLET TRAILBLAZERS AND GMC ENVOYS. THERE NEEDS TO BE A RECALL AS THIS IS A VERY COMMON PROBLEM AND THE DEALER WANTS $600 TO REPAIR THIS PROBLEM. *TR

HVAC BLOWER STOPPED WORKING ON HI SPEED. VEHICLE INTERIOR LIGHTS DIMMED FOR ABOUT 1 SEC CORRESPONDING TO THE INSTRUMENT PANEL VOLTMETER FALLING TO THE LOW END OF NORMAL. THE INTERIOR LIGHTS RETURNED TO NORMAL BRIGHTNESS AND THE VOLTMETER RETURNED TO ITS NORMAL POSITION WITH ENGINE RUNNING-A LITTLE ABOVE THE MIDDLE INDICATING CHARGING CONDITION. UPON INSPECTION THE BLOWER RESISTOR AND HARNESS MELTED TOGETHER. PIN G OF THE BLOWER RESISTOR MELTED THE PLASTIC AROUND IT. REPLACED THE BLOWER RESISTOR. NOTE: NO FUSES BLEW. OLD PART IS AVAILABLE. *LN

OUR 2005 CHEVY TRAILBLAZER SPEEDOMETER JUST QUIT WORKING. WE CAN BE SITTING AT A COMPLETE STOP AND THE SPEEDOMETER WILL READ 50MPH. IT WILL RANDOMLY CHANGE AND LATER WILL EVEN DROP BELOW THE ZERO MARK. WE HAVE NO IDEA HOW FAST WE ARE TRAVELING WHEN THIS OCCURS. YESTERDAY, WHILE DRIVING FROM OH TO IN, I HAD TO GUESS HOW FAST I WAS GOING ON THE FREEWAY. THE SPEEDOMETER STARTED OUR READING 45MPH, SO I ESTIMATED THAT I HAD TO TRAVEL AT 110 MPH TO GO 65MPH. THE PROBLEM BECAME WORSE WHEN I NOTICED THAT MY SPEEDOMETER WAS JUMPING FROM ONE SPEED TO THE NEXT, NOT GRADUALLY CLIMBING LIKE IT SHOULD HAVE BEEN. THIS PROBLEM IS A RANDOM OCCURRENCE. I NEVER KNOW WHEN TO EXPECT IT. OBVIOUSLY, THERE ARE SERIOUS CONSEQUENCES THAT CAN ENSUE. SPEEDING TICKETS, ENDANGERING OTHERS' AS WELL AS OUR OWN LIVES BY DRIVING TOO FAST OR TOO SLOW, OR CAUSING ACCIDENTS IN GENERAL. NOTHING HAS BEEN DONE TO CORRECT THE PROBLEM SINCE THE CAR IS OUT OF WARRANTY AND I AM UNDEREMPLOYED AND WE CANNOT AFFORD TO REPLACE THE INSTRUMENT CLUSTER AT THIS TIME. *LN

GM INITIATED CONTACT IN DECEMBER OF 2010 AND TOLD ME TO GET A FULL DIAGNOSIS OF THE PROBLEMS AND STATED THAT IT WAS OK TO GO TO THE FORMER GM DEALER.
