2004 GMC SIERRA 1500 Complaints

2004 GMC SIERRA PICKUP SPEEDOMETER IS VERY ERRATIC. INDICATED SPEEDS ARE NOT ACCURATE. SOMETIMES SPEEDOMETER INDICATES 40-60 MPH WHEN TRUCK IS NOT MOVING. *NM

MY 2004 GMC SIERRA WOULD LIGHT ALL FOUR TURN SIGNALS WHEN THE LEFT TURN SIGNAL WAS APPLIED, AS IF THE HAZARD LIGHTS WERE ON. TOOK IT TO DEALER AND THEY SAID THEY HAD NEVER SEEN ANYTHING LIKE IT BEFORE. PAID ALMOST 200 DOLLARS TO GET IT LOOKED AT AND FIXED. AFTER GOING HOME, I SEE THAT OTHER SIERRA USERS HAVE THE SAME PROBLEM. MORE SHOCKING, I SEE THAT GM HAD THE EXACT SAME PROBLEMS WITH SOME ENVOYS, BARBADOS, TRAILBLAZERS, AND OTHERS, AND PERFORMED A SAFETY RECALL AT NO CHARGE. IT IS OUTRAGEOUS THAT ALL VEHICLE OWNERS WITH THESE PROBLEMS WERE NOT NOTIFIED AND THE FAULTY COMPONENTS REPLACED. HAVE BEEN TRYING TO GET IN TOUCH WITH GM ABOUT THIS AND THEY HAVE YET TO SEND ME ANYTHING BUT CARBON-COPY E-MAILS AND RUNAROUNDS. *JB

SPEEDOMETER FAILS TO RESET TO ZERO. WHEN VEHICLE COMES TO A STOP, THE SPEEDOMETER INDICATOR STOPS AT A SPEED ABOVE ZERO (I.E., 30, 40, 50 MPH). WHEN THE VEHICLE RESUMES TRAVELING, THE SPEEDOMETER INDICATOR STARTS INCREMENTING AT THE SPEED AT WHICH IT STOPPED (I.E., 30, 40, 50 MPH). THEREFORE, THE INDICATED SPEED IS MUCH HIGHER THAN THE ACTUAL SPEED. THIS IS NOT ONE INCIDENT, BUT AN ONGOING CONTINUOUS PROBLEM, AND VERY DANGEROUS. *NM

2004 GMC SIERRA AT 50,000 MILES DEVELOPED A SPEEDOMETER SHORT IN THE INSTRUMENT CLUSTER WHICH CAUSED WILD SWINGS IN MPH READINGS. AFTER MENTIONING IT TO A FRIEND WITH A CHEVY SILVERADO, SAME YEAR AND MILEAGE , I FOUND HE HAD THE IDENTICAL PROBLEM . I HAD THE CLUSTER REPLACED AT MY COST.*JB

SPEEDOMETER IS ERRATIC IN FUNCTION I HAVE 44,000 MILES ON MY 2004 GMC SIERRA AND THE SPEEDOMETER IS IN NEED OF REPAIR OR REPLACEMENT. *NM

SPEEDOMETER ACTING ERRATIC, SPEEDOMETER MAY REGISTER 120 MPH WHEN I'M GOING 60 MPH. THEN IT FINALLY QUITS. IT COSTS A LOT OF MONEY TO GET REPLACED. I DO NOT KNOW HOW FAST OR SLOW I'M GOING WHICH ENDANGERS ME AND EVERYBODY AROUND ME. *JB

MY SPEEDOMETER ON MY 2004 GMC SIERRA HAS BECOME ERRATIC. SOMETIMES IT IS ZERO EVEN IF THE VEHICLE IS MOVING. SOMETIMES IT REGISTERS 120 MPH SITTING STILL. IT IS VERY DIFFICULT TO JUDGE SPEED IN SCHOOL ZONES. NO KNOW EVENTS LED TO THE FAILURE. THE REPAIR BILL WILL BE ABOUT $500 I AM TOLD. *NM

DT*: THE CONTACT STATED WHILE APPLYING SUDDEN BRAKE PRESSURE AT VARIOUS SPEEDS, THERE WAS AN INCREASED STOPPING DISTANCE. THIS WAS INTERMITTENT IN NATURE. THE VEHICLE WAS INSPECTED NUMEROUS TIMES BY THE DEALER WHO WAS UNABLE TO DUPLICATE THE PROBLEM. THE MANUFACTURER WAS ALERTED.

DT*: THE CONTACT STATED WHILE DRIVING 75 MPH ON THE INTERSTATE, THE SPEEDOMETER GAUGE BEGAN TO DECREASE AND INCREASE WITHOUT WARNING PRODUCING ERRONEOUS READINGS CONTRARY TO THE ACTUAL MILES PER HOUR BEING DRIVEN. ALTHOUGH THE PROBLEM PERSISTED, THE DEALER AND MANUFACTURER WERE NOT ALERTED. *AK UPDATED 11/0/906.*JB

MY SPEEDOMETER ON MY 2004 GMC Z71 WORKS ERRATICALLY. SOMETIMES IT WILL PEG OUT AT 120 OR IT STICKS AT 70 MPH. WHEN I SEE THE SPEEDOMETER, IT SEEMS LIKE IT IS WORKING LIKE A CLOCK. IT STICKS AND RELEASES. *NM
