2004 CHEVROLET TRAILBLAZER EXT Complaints

WHILE EXITING MY CHILD SCHOOL PARKING LOT THE ENGINE SHUT DOWN AND WENT INTO LIMP MODE. I WAS IN THE MIDDLE OF A BUSY INTERSECTION, HAD TO TURN HAZARD LIGHTS ON SO I WASN'T HIT. COULD NOT GO OVER 5 MILES PER HOUR. SPEEDOMETER HAS INTERMITTENTLY GONE HAYWIRE. INSTRUMENT CLUSTER FAILURE. *TR

THE INSTRUMENT CLUSTER IS ERRATIC, SPEED SHOW ZERO, TACH IS NOT WORKING AT ALL NOW, THE OIL PRESSURE AND VOLT METER IS ERRATIC. THIS IS A UNSAFE DRIVING CONDITION NOT KNOWING IF YOU ARE GOING AT A UNSAFE SPEED OR IF YOU ARE DOING DAMAGE TO THE MOTOR WITH THE OIL PRESSURE IS SO ERRATIC. *TR

INSTRUMENT CLUSTER GOES CRAZY. NO OIL PRESSURE/EXCESSIVE OIL PRESSURE, NO TACH/PEGGED TACH, SPEEDOMETER GIVES FALSE SPEED READINGS(THIS IS REALLY DANGEROUS), BATTERY READS LOW VOLTS OR OFF THE SCALE VOLTS/. THIS HAPPENS EVERY DAY. CHEVY DEALERS ESTIMATED REPAIR COST $600-$700 DOLLARS. *TR

THE SPEEDOMETER HAS BECOME ERRATIC AND WILL NOT SHOW HOW FAST WE ARE DRIVING, CAUSING AN UNSAFE CONDITION. BASED ON THE NUMBER OF POSTS ON SEVERAL FORUMS, THIS APPEARS TO BE A VERY COMMON PROBLEM, AND WITH TIME MAY BECOME UNIVERSAL. *TR

THE SPEEDOMETER STICKS AND DOES NOT GIVE ACCURATE READINGS OF SPEED (I.E. 70MPH WHEN STOPPED AT TRAFFIC LIGHT). THIS BEGAN TODAY AND HAS NOT CORRECTED ITSELF. THERE ARE SERIOUS POTENTIAL CONSEQUENCES OF THIS PROBLEM AS DRIVERS WILL NOT BE ABLE TO KNOW THEIR TRUE SPEED. NOTHING HAS BEEN DONE YET TO CORRECT THE FAILURE. RESEARCH HAS SHOWN AVERAGE PRICE OF REPAIR TO BE AROUND $450.00. *TR

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

THE ODOMETER AND RPM GAUGE STOP FUNCTIONING. WHILE YOU ARE DRIVING THE ODOMETER STOPS BELOW THE ZERO AND STAYS STUCK, IT WILL STOP AT 50 AND STAY THERE, IT WILL STOP ON 120 AND STAY THERE. THE ODOMETER GAUGE SOMETIMES WILL STOP BELOW THE 120 RIGHT ABOVE THE DIGITAL MILEAGE GAUGE. *TR

POWER STEERING PUMP NEEDS REPLACED. OTHER SUV OWNERS HAVE TOLD ME THE SAME THING HAPPENED TO THEIR VEHICLE THAT HAD THE SAME PUMP. *TR

THE INSTRUMENT GAUGES, INCLUDING SPEEDOMETER ARE PRODUCING ERRATIC DATA, SOMETIMES 25-30 MPH FAST OR SLOW TO THE ACTUAL SPEED AS TRACKED BY A GARMIN GPS, AND MILEMARKER CALCULATIONS. THE OIL PRESSURE AND AMP GAUGES ARE NOT WORKING PROPERLY AS WELL. *TR

SPEEDOMETER STARTED TO ACT ERRATIC AT ABOUT 40K MILES. NOW AT 72K MILES, DOES NOT WORK AT ALL. I JUST SPENT $200 TRYING TO REPAIR, ONLY TO FIND OUT AFTER THAT FAILED, THAT THIS IS A COMMON PROBLEM WITH GM. HOW CAN THEY JUSTIFY RECALLING THE TAHOES, AVALANCHES, ETC, FOR THE SAME PROBLEM, BUT LEAVING THE TRAILBLAZERS OUT OF THIS SAFETY RECALL? *TR
