NHTSA Complaint #10389870 — 2002 CHEVROLET TRAILBLAZER

BOUGHT 2002 CHEVROLET TRAILBLAZER WHICH OPERATED FINE UNTIL 2 YRS AGO. FIRST, THE SPEEDOMETER GOES NUTS, THE NEEDLE REGISTERS FASTER SPEEDS THAN CAR IS GOING. SOME DAYS IT WOULD WORK, SOME DAYS IT WOULD NOT. NOW IT POINTS PAST 120 MPH, DIRECTLY DOWNWARDS, STUCK THERE AND DOES NOT MOVE AT ALL. SITTING STILL IN MY DRIVEWAY THE SPEEDOMETER SHOWS ITS GOING OVER 120 MPH. THE GAS GAUGE GOES NUTS NEXT. THE NEEDLE GOES PAST FULL AND BACK AROUND TO THE GAS PUMP ICON AND STAYS THERE. THE TACHOMETER FOLLOWED SUIT DOING THE SAME THING AND INDICATING RPMS PAST THE 9000 RANGE AND DOESN'T SETTLE BACK AT ZERO WITH ENGINE OFF. AND NOW THE TEMP GAUGE IS SHOWING 200 - 250 DEGREES WHEN THE ENGINE IS STARTED. AS FAR AS I CAN TELL THE VOLTAGE AND BATTERY GAUGES ARE STILL SHOWING NORMAL READINGS - SO FAR. AM I SPEEDING, IS MY ENGINE ABOUT TO BLOW UP, OR AM I GOING TO RUN OUT OF GAS? I HAVE NO WAY OF KNOWING IF I AM DRIVING THE SPEED LIMIT OR UNKNOWINGLY SPEEDING, NO IDEA HOW MUCH GAS IS IN THE TANK, UNAWARE THAT MY ENGINE IS REVVING UP INTO A DANGEROUS RANGE OR ABOUT TO BLOW UP; OR IF MY ENGINE IS DANGEROUSLY OVERHEATING. I DEPEND ON THE INSTRUMENT CLUSTER TO ALERT ME TO THOSE DANGERS. THERE SHOULD HAVE BEEN A RECALL ON THESE FAILING INSTRUMENT CLUSTERS A LONG TIME AGO BUT ALTHOUGH HUNDREDS HAVE COMPLAINED GM SAYS THEY WON'T FIX THIS ISSUE ON THE TRAILBLAZER. THEY DON'T CARE THAT WE TRAILBLAZER OWNERS MUST DRIVE OUR VEHICLES WITHOUT WORKING INSTRUMENTS. THIS SITUATION IS DANGEROUS. *TR
