2004 Chevrolet Silverado 2500

SPEEDOMETER MALFUNTIONED ON MY 2004 CHEVROLET SILVERADO 2500HD. I NOTICED THE MALFUNTION ON THE INTERSTATE WHILE TRAVELING AT SAME SPEED AS OTHER DRIVERS. MY SPEEDOMETER WAS READING 50 MILES PER HOUR AND THE POSTED SPEED LIMIT WAS 70 MILES PER HOUR. I KNOW THAT THE AVERAGE SPEED ON THAT ROUTE IS BETWEEN 70 AND 75 MILES PER HOUR. IF SOMEONE WERE TO DRIVE THROUGH A SCHOOL ZONE WITH THE SPEEDOMETER READING 20 MILES PER HOUR AND WERE TO INJURE A CHILD WHILE THE ACTUAL SPEED TRAVELED WAS IN THE 40-45 MILE PER HOUR RANGE IT WOULD BE GM'S FAULT. IT IS WELL KNOWN TO CHEVY OWNERS THAT THERE IS A DEFECT IN THIS PARTICULAR INSRUMENT CLUSTER AND WELL KNOWN TO GM. SOMETHING SHOULD HAVE ALREADY BEEN DONE, BUT AS OF TODAY NO RECALLS HAVE TAKEN EFFECT. *NM

SPEEDOMETER NEEDLE DOES NOT RECORD SPEED ACCURATELY, RESULTING IN VEHICLE TRAVELING EITHER MUCH FASTER, OR MUCH SLOWER THAN THE SPEED INDICATED (ONBOARD COMPUTER INDICATED I WAS TRAVELING AT 92 MPH, WHILE THE SPEEDOMETER RECORDED 66; ANOTHER TIME THE ONBOARD COMPUTER INDICATED I WAS TRAVELING 56 MPH WHILE THE SPEEDOMETER INDICATED 87). EVENTUALLY, THE SPEEDOMETER NEEDLE PEGS TO 120 MPH AND STAYS THERE. IN RESEARCHING THIS ISSUE, I HAVE SEEN LITERALLY HUNDREDS OF COMPLAINTS OF THIS SAME PROBLEM. THE LOCAL DEALER SAID THEY HAVE BEEN FIXING A LOT OF THESE SPEEDOMETER PROBLEMS; PROBLEM IS WITH SPEEDOMETER NEEDLE ONLY (THE COUNTER WEIGHT FOR THE NEEDLE, OR THE PROBLEM WITH THE SPEEDOMETERS IN 2003 AND UP CHEVY TRUCKS IS CAUSED BY A TINY BROKEN GEAR IN THE ACTUAL METER MOVEMENT. THE GEAR IS A SMALL PIECE OF CYLINDRICAL METAL SURROUNDED BY A PLASTIC GEAR - THE GEAR IS HELD IN PLACE BY 3 PLASTIC RIBS. ONE OF THE RIBS CRACKS CAUSING AN OFFSET. IF YOU PICTURE THE GEAR AS A CHILD'S TOP - WHEN YOU NORMALLY SPIN THE TOP IT SPINS STRAIGHT UP AND DOWN. BECAUSE THE RIB BREAKS IT CAUSES THE GEAR TO BE OUT OF BALANCE AND THUS THE ROTATION THEN "WOBBLES". THIS CAUSES THE GEAR TO GET STUCK AT VARIOUS LOCATIONS. GM KNOWS OF THIS PROBLEM.. 2004 CHEVROLET SILVERADO 2500 HD (ALSO MANY OTHER COMPLAINTS WERE RELATIVE TO SILVERADO 1500). *NM

INJECTORS NUMBER 2 AND 7 LOOSE CONNECTOR AND OIL PUMP RUBBING THROUGH TRANSFER CASE ON CHEVY SILVERADO HD2500 TRAVELING DOWN THE HIGHWAY PULLING A HORSE TRAILER THE TRUCK WENT INTO LIMP MODE AND WOULD NOT KEEP UP WITH HIGHWAY SPEED. HAD TO PULL OVER ON AN INTERSTATE AND ATTEMPT A QUICK REPAIR ALONG THE ROAD. TRANSFER CASE HAS NOT YET CAUSED A PROBLEM, HOWEVER, THE ALUMINUM RESIDUES IN THE CASE OIN ARE VERY HIGH AND WHEN PUMP GOES THROUGH CASE ALL OIL WILL BE LOST AND THE VEHICLE WILL STOP. *NM

DT*: THE CONTACT STATED WHILE DRIVING 25 MPH ON NORMAL ROAD CONDITIONS DURING RUSH HOUR, THE BRAKE PEDAL WENT TO THE FLOOR WITHOUT ANY BRAKE ACTION WHEN BRAKING WAS ATTEMPTED. THERE WERE NO WARNING SIGNALS. THE VEHICLE WAS TOWED TO THE DEALERSHIP WHO COULD NOT DETERMINE ANY BRAKE PROBLEM. THE VEHICLE WAS TAKEN TO THE DEALERSHIP THREE TIMES WITHOUT ANY DIAGNOSTIC OR REPAIR. THE MANUFACTURER WAS CONTACTED, AND OPENED THE CASE # 14336544837. THE CONTACT WAS CALLED BACK TO INFORM THE CASE WAS CLOSED.

DT*: THE CONTACT STATED THE VEHICLE'S TIRE HUBS ARE SEALED UNITS AND COULD NOT BE REPACKED WITH GREASE. THE HUB ASSEMBLY WAS LOOSE WHICH CAUSED THE BEARINGS TO BECOME DEFECTIVE RESULTING IN WOBBLING TIRES. THE FRONT HUBS HAD TO BE REPLACED TWICE HOWEVER THE SERVICE DEALER COULD NOT DETERMINE WHY THE BEARINGS WERE BECOMING DEFECTIVE. ALSO, THERE WAS OIL LEAKING OUT OF THE EGR VAVLE. THE EGR VALVE WAS REPLACED WHICH CORRECTED THE PROBLEM. THEN VEHICLE WAS SURGING AND WOULD NOT ACCELERATE. WHEN THE VEHICLE WAS TAKEN TO THE DEALER THE VEHICLE'S EGR VALVE WAS REPLACED AGAIN WHICH ALSO CORRECTED THE PROBLEM. UPDATED 11/06/06.*JB
