2003 Chevrolet Trailblazer vehicle speed control problems

“MULTIPLE GAUGES ON THE INSTRUMENT PANEL ARE MALFUNCTIONING. THE TACHOMETER IS READING 5,000 RPM WHEN THE VEHICLE WAS IN PARK, AND 7,000 RPM WHEN GOING 15 MPH. WHEN I TURN THE CAR OFF THE GAUGE SITS AT 2,000. THE SPEEDOMETER IS CLICKING UP (NOT A SMOOTH TRANSITION TO THE CORRECT SPEED). AND IT SHOWING A LESSER SPEED THEN I AM GOING. WHEN I TURN THE CAR OFF THE SPEEDOMETER SHOWS IT IS GOING 10 MILES PER HOUR BUT WILL SLOWLY DROP DOWN TO ZERO. BOTH OF THESE MALFUNCTIONS COULD ARE A HUGE SAFETY CONCERN. I HAD TO PULL OVER ON THE HIGHWAY WHILE THE INSTRUMENT PANEL WAS SHOWING 7,000 RPM, AFRAID I WAS GOING TO BREAK DOWN AND RUIN MY CAR.”

“THE PROBLEM HAPPENS WHEN COMING TO A STOP THE ENGINE WILL SURGE OR JUMP AS MUCH AS 2000 RPM'S AND YOU REALLY HAVE TO BE ON THE BRAKE TO HOLD IT. GO TO NEUTRAL LET IT REV THEN IT WILL COME BACK TO NORMAL. THE LAST TIME WAS ON A SNOW PACKED INTERSECTION WITH TWO OTHER VEHICLES IN OPPOSITE DIRECTIONS. THE BAD THING IS YOU DON'T KNOW WHEN IT'S GOING TO DO IT. HAD IT TO SEVERAL GARAGES AND NOBODY CAN DUPLICATE IT AND IT SHOWS NO CODES. *TR”

“AUTOMATIC DRIVE SHIFT LINKAGE DISCONNECTED DUE TO FAILURE OF WHAT APPEARS TO BE A SMALL PLASTIC RIVET THAT HELD THE LINKAGE COMPONENTS TOGETHER. TRANSMISSION COULD NOT BE SHIFTED OUT OF DRIVE, NOT EVEN TO NEUTRAL. COULD ONLY STOP CAR BY COMING TO A COMPLETE STOP WITH THE BRAKES, TURNING OFF THE IGNITION KEY, AND THEN APPLYING THE EMERGENCY BRAKE. CALLED DEALER AND THEN TOW TRUCK. WHEN THE TOWER ARRIVED, HE LOOKED AT THE MAKE/MODEL OF THE VEHICLE AND AS I DESCRIBED WHAT HAD HAPPENED HE SAID HE KNEW WHAT THE PROBLEM WAS BECAUSE HE HAD PICKED UP 6 OF THE SAME VEHICLE IN THE LAST 2-3 MONTHS FOR THE SAME PROBLEM. WHEN HE CHECKED, HE WAS CORRECT, THE LINKAGE HAD BECOME DISCONNECTED DUE TO A BROKEN PLASTIC RIVET. *TR”

“TL* THE CONTACT OWNS A 2003 CHEVROLET TRAIL BLAZER. THE CONTACT WAS DRIVING 45 MPH WHEN HE NOTICED THAT THE VEHICLE WOULD NOT ACCELERATE. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS WHO STATED THAT THEY NEEDED TO REPLACE THE FAN CLUTCH. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS CONTACTED. THE FAILURE AND THE CURRENT MILEAGE WAS 84,000. UPDATED 9/25/12 *CN”

“I, ALONG WITH MANY OTHERS ARE EXPERIENCING MAJOR PROBLEMS WITH THE INSTRUMENT PANELS ON OUR CHEVROLET TRAILBLAZER. MY MOTHER TRADED HERS IN BECAUSE HER SPEEDOMETER WAS GOING OUT. BUT MY PROBLEM IS MUCH WORSE, MY WHOLE ENTIRE DASHBOARD IS OUT. MY GAS GAUGE DOESN'T WORK, MY SPEEDOMETER DOESN'T WORK, MY OIL PRESSURE DOESN'T WORK, MY THERMOSTAT DOESN'T WORK, NOTHING WORKS. MY CRUISE CONTROL ACTS UP TOO. *TR”

“I AM A SENIOR CITIZEN I BROUGHT THIS CAR NEW. AFTER ONE YEAR I HAD TO REPLACE LINC PLATE. OVER THE YEARS EVERYTHING HAS GONE WRONG WITH THIS CAR. SPEEDOMETER HAS NOT WORKED SINCE AUG. '08, GAS GAUGE STOPPED OCT. '11. INSTRUMENT CLUSTER SINCE 2010 AND GM KNOWS THIS IS A DEFECTED PART. YET GM PAID FOR THIS SAME DEFECTED PART AT THEIR COST FOR THE TAHOE, BUT HAS NOT PAID FOR THE TRAILBLAZER. WHY? WINDOWS AND DOORS DO NOT UNLOCK ON COMMAND. WINDOW WIPER(REAR) STOPPED WORKING-I REPLACED THAT PART. A/C COMES ON MY ITSELF. THERMOSTAT FAILURE. I THINK GM SHOULD STAND BEHIND THEIR PRODUCT. THE ONLY REASON THEY WOULD NOT IS THAT THEY ALREADY KNOW THAT THEY ARE PRODUCING SUBSTANDARD PRODUCTS THAT ARE NOT FIT TO BE DRIVEN ON THE ROAD. *TR”
