2003 GMC SIERRA Vehicle Speed Control Problems

WHEN TRAVELING AT A SLOW SPEED, LESS THAN 10 MILES PER HOUR, IF BRAKE IS APPLIED THE PEDAL RUMBLES AND THE TRUCK CONTINUES TO MOVE UNLESS I PUMP THE BRAKES. THIS IS HAPPENING DURING CLEAR DAYS NO RAIN, SNOW OR LOOSE GRAVEL. THIS INCIDENT IS VERY SIMILAR TO THE ONE DESCRIBED IN CAMPAIGN NUMBER: 05V379000. *TR

TL*THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE SPEED CONTROL NEEDLE STOPPED WORKING AND IT IS CURRENTLY STUCK AT 120 MPH. WHILE DRIVING 30 MPH, THE VEHICLE SPEED CONTROL DISPLAYED 80 MPH. THE VEHICLE WAS TAKEN TO THE DEALER FOR REPAIR AND THEY STATED THAT IT WOULD COST $600, IN WHICH HE WOULD BE RESPONSIBLE FOR PAYING. THE GM MANUFACTURER ALSO STATED THAT HE WOULD BE LIABLE FOR THE SPEED CONTROL REPAIR. THE CURRENT AND FAILURE MILEAGES WERE 44,550.

AFTER SITTING IN STOP-AND-GO TRAFFIC I NOTICED THAT THE SPEEDOMETER WAS READING AT 100 MPH AND I WAS AT A STOP LIGHT. AT THE TIME, I HAD LESS THAN 50,000 MILES ON MY TRUCK. SINCE THEN THE SPEEDOMETER WAS ALMOST ALWAYS INCORRECT. IT HAS OCCASIONALLY FIXED" ITSELF, BUT USUALLY DID NOT LAST MORE THAN A DAY OR TWO. THE NEEDLE WAS OFTEN BURIED PAST 120 MPH. A NUMBER OF MY FRIENDS AND RELATIVES WITH SIMILAR VEHICLES HAD THE SAME PROBLEM. CURRENTLY I HAVE NOT PAID TO HAVE THE PROBLEM FIXED, BUT HOPE THAT IT WILL BE RECALLED AT SOME POINT SOON.*AK

DRIVING MY 2003 GMC SIERRA AND THE SPEEDOMETER WENT OUT , IT WAS GOING 100 MILES PER HOUR WHEN I WAS GOING AROUND 50 - 55 ? HARD TO TELL IT NEVER RIGHT ANY MORE AND I ONLY HAVE 58,000 ON THE ODOMETER . THIS A SAFETY PROBLEM AND GMC SHOULD RECALL THESE CLUSTERS BEFORE PEOPLE START GETTING HERT BECAUSE THE SPEED IS WAY OF , AND THE DEALERS WANT USE TO PAY AROUND 1200.00 TO FIX. THIS IS A GMC FIX NOT. *JB

DT*: THE CONTACT STATED THE SPEEDOMETER INSTRUMENT PANEL STOPPED WORKING WITHOUT PRIOR WARNING. THE DEALER SUGGESTED REPLACING THE SPEEDOMETER INSTRUMENT CLUSTER PANEL. ALTHOUGH THE VEHICLE WAS SEEN BY A DEALER, NO REPAIRS WERE MADE. UPDATED 02/21/06 .*JB

DT: THE CONTACT COMPLAINED ABOUT MANY DEFECTS WITH THIS VEHICLE. THE SPEEDOMETER CONTINUALLY HAD AN INACCURATE READ OUT WHILE DRIVING. THE DEALERSHIP BELIEVED THIS FAILURE COULD BE RELATED TO THE WIRING HARNESS. SINCE THEY WERE UNABLE TO DUPLICATE THE PROBLEM NO REPAIRS WERE DONE. ALSO, THE VEHICLE STALLED AT VARIOUS SPEEDS WITHOUT WARNING. WHILE THE STALLING OCCURRED THE CONTACT PRESSED HARD ON THE BRAKES TO ELEVATE THE STALLING. HE BELIEVED THIS WAS DUE TO THE POWER BRAKES. THE VEHICLE STALLED ON OCCASION AND WOULD NOT IMMEDIATELY RESTART. THE DEALERSHIP MADE NUMEROUS ATTEMPTS TO CORRECT THIS PROBLEM W AND ALL ATTEMPTS HAVE BEEN UNSUCCESSFUL. THIS INCLUDED REPLACING THE FUEL PUMP AND ELECTRICAL CONTROL MODULE. *AK

WHILE DRIVING, COMING TO A COMPLETE SUDDEN STOP, AND UPON DEPRESSING THE BRAKES PEDAL, THEY WENT COMPLETELY TO THE FLOOR, AND THE VEHICLE WOULD NOT STOP. THE CONSUMER THEN PLACED BOTH FEET ON THE BRAKES TRYING TO STOP THE VEHICLE, THE VEHICLE ACCELERATED, RESULTING IN AN ACCIDENT. THE CONSUMER REAR ENDED ANOTHER VEHICLE. *AK THE CONSUMER REQUESTED TO BE REIMBURSED FOR THE EXPENSES. *SC *JB

WHILE DRIVING ANY SPEED, THE SPEEDOMETER WOULD READ THE WRONG SPEED. THE CAUSE WAS NOT DETERMINED. PLEASE PROVIDE MORE INFORMATION. *JB

WHEN DRIVING THE VEHICLE WITH THE CRUISE CONTROL ON THE VEHICLE SURGED FORWARD THEN DECELERATED BACK TO ITS ORIGINAL SPEED AFTER 3 TO 4 SECONDS. THE CONSUMER HAD MADE CONTACT WITH THE DEALERSHIP. *JB WHEN THE VEHICLE WAS EMPTY, THEN IT WOULD WORK AS IT SHOULD. IF A TRAILER WAS HOOKED WITH 400 LBS, THE CRUISE CONTROL WOULD GO FROM 1500 RPM TO 45 OR 4600 RPM'S FOR ABOUT 3 TO 4 SECONDS, THEN DROP DOWN TO 2600 RPM OR 3500 RPM'S DEPENDING ON THE HILL THE DRIVER WAS GOING UP AND WOULD STAY THAT RPM UNTIL THE DRIVER WAS AT THE TOP. THREE DEALERS SUGGESTED THAT THEY COULDN'T REMEDY THE PROBLEM. *SC *JB

WHEN USING FEATURE "FLY BY WIRE THROTTLE" THE ACCELERATOR CANNOT BE CONTROLLED.*MR WHEN ENCOUNTERING ANYTHING MORE THAN THE SLIGHTEST BUMP OR VARIATION IN THE ROAD OR ON THE HIGHWAY, IT WAS IMPOSSIBLE TO KEEP CONSTANT PRESSURE ON THE ACCELERATOR. WHEN THE VEHICLE WENT OVER A BUMP ETC. ACTION WAS UNABLE TO BE CONTROLLED AND THE ACCELERATOR WAS SEVERELY DEPRESSED WHICH CAUSED AN INCREASE IN SPEED AND THEN A VOLUNTARY RELEASE OF THE ACCELERATOR, EVEN WHEN THE CONSUMER KNEW HE WAS APPROACHING A BUMP, HE WAS UNABLE TO CONTROL THE ACCELERATOR. *TS *JB
