2004 GMC Sierra 1500

TL*THE CONTACT OWNS A 2004 GMC SIERRA 1500. WHILE DRIVING 40 MPH, THE CONTACT HEARD A CLUNKING NOISE COMING FROM THE STEERING COLUMN. THE DEALER STATED THAT THE WRONG LUBRICATING GREASE WAS APPLIED TO THE STEERING COLUMN. THEY REPLACED THE GREASE, BUT THE FAILURE RECURRED TWO YEARS LATER. AS OF OCTOBER 17, 2007, THE DEALER HAD NOT INSPECTED THE VEHICLE. THE FAILURE MILEAGE WAS 10,000 AND CURRENT MILEAGE WAS 43,000.

TL*THE CONTACT OWNS A 2004 GMC SIERRA 1500. WHILE DRIVING 65 MPH AND APPROACHING A STOP, THE SPEEDOMETER CONTINUED TO DISPLAY THAT THE VEHICLE WAS TRAVELING 65 MPH. AFTER RESUMING AT APPROXIMATELY 25 MPH, THE SPEEDOMETER DISPLAYED 75 MPH. WHEN THE CONTACT TURNED OFF AND RESTARTED THE VEHICLE, THE SPEEDOMETER WENT FROM 70 - 140 MPH BEFORE HE RESUMED DRIVING. THE SPEEDOMETER REMAINED THERE AFTER THE VEHICLE WAS TURNED OFF AND HAS NOT CHANGED. THE VEHICLE HAS NOT YET BEEN DIAGNOSED. THE PURCHASE DATE WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 62,000.

I HAVE HAD TWO OCCURRENCES WHERE THE SPEEDOMETER STICKS AND/OR REGISTERS SPEEDS DIFFERENT FROM WHAT IS BEING DRIVEN. IN THE LATEST INSTANCE, WHILE DRIVING 65 MPH ON AN INTERSTATE IT STARTED FLUCTUATING TO WHERE IT WAS REGISTERING 120 MPH. WHEN I STOPPED AT A TRUCK STOP AND SHUT THE ENGINE OFF IT WAS STILL REGISTERING 40 MPH. THE FIRST TIME THIS HAPPENED, I WAS DRIVING IN HEAVY RAIN. I THOUGHT POSSIBLY THE RAIN MAY HAVE HAD SOMETHING TO DO WITH IT IF MOISTURE HAD GOTTEN IN TO THE ELECTRONICS SOMEWHERE. AFTER A FEW DAYS IT STARTED WORKING NORMALLY AGAIN UNTIL LAST NIGHT. *TR

REDUCED ENGINE POWER, THIS HAS HAPPENED ABOUT 7 TIMES. WHEN THIS HAPPENS THE ENGINE SHUTS DOWN TO 1500 RPMS MAXIMUM. TOOK TO DEALER, THEY TOLD ME THAT IT WAS THE THROTTLE BODY VALVE AND ACTUATOR ASSEMBLY. THIS PART WAS REPLACED AT A COST OF $481. WITHIN TWO WEEKS THE SAME PROBLEM HAS HAPPENED TWICE MORE. THIS IS DANGEROUS WHEN TRAVELING IN TRAFFIC. *TR

MY 2004 GMC SIERRA 1500 HAS ERRATIC SPEEDOMETER MALFUNCTIONS. I FIRST NOTICED THIS ON A TRIP WITH MY SPEEDOMETER READING 65 MPH AND ALL THE TRAFFIC OF A 4 LANE EXPRESSWAY WAS PASSING ME. I THEN REALIZED MY PORTABLE GPS UNIT WAS READING A MUCH SLOWER SPEED. SPEEDING UP TO THE GAPS READING MY TRUCK SPEEDOMETER REGISTERED 110 MPH. AT TIMES THE READINGS ARE REVERSED. AND AT OTHER TIMES THE SPEEDOMETER DOESN'T WORK AT ALL. AFTER RESEARCH ON THE INTERNET I?VE DISCOVERED GM HAS USED FAULTY ?CLUSTER STEPPER MOTORS? AND MANY CUSTOMERS ARE HAVING THIS SAME PROBLEM AND GM KNOWS ABOUT THE PROBLEM. FORTUNATELY THERE HAVEN?T BEEN ANY REPORTED DEATHS YET DUE TO THE PROBLEM ONE WOULD HOPE THAT A RECALL WOULD RESULT BEFORE THERE ARE FATALITIES. *JB

SPEEDOMETER STOPS WORKING AT TIMES, GETS STUCK AROUND 70MPH WHILE DRIVING SOMETIMES AT OTHER SPEEDS. WHEN THE TRUCK IS TURNED OFF IT DOES NOT GO TO ZERO INSTEAD IT GOES TO 20-40MPH AND THEN I GUESS IT THINKS THAT'S WHERE ZERO STARTS. TRUCK ONLY HAD 42,000 MILES WHEN THESE PROBLEMS STARTED AND IT SEEMS TO BE GETTING WORSE. THE TRUCK IS A 2004 GMC SIERRA Z71 ALMOST NEW. SOMETIMES I DON'T KNOW HOW FAST I'M GOING WHEN THIS HAPPENS. *TR
