2004 GMC Yukon

I PURCHASED A 2004 GMC YUKON, IN 2005. OVER THE LAST 6 MONTHS OR SO, MY SPEEDOMETER HAS BEEN ACTING ERRATICALLY - WHEN IT IS HOT OR HUMID THE SPEEDOMETER STARTS TO JUMP A LITTLE THEN STARTS TO REGISTER A HIGHER SPEED THAN I AM MOVING. FOR EXAMPLE: I WAS SITTING AT A STOP LIGHT AND MY SPEEDOMETER READ 90 MPH. I NOTICED THAT WHEN I WOULD TURN OFF THE ENGINE AND REPEATEDLY START UP AND SHUT OFF THE ENGINE, THE SPEEDOMETER READING WOULD REDUCE BY APPROXIMATELY 5 MPH AT A TIME, WHICH MEANS I HAD TO START UP AND SHUT OFF THE ENGINE 18 OR MORE TIMES FOR IT TO RETURN TO 0. THIS HAPPENS QUITE OFTEN. I CONTACTED MY LOCAL GMC DEALER REPAIR DEPARTMENT WHO KNEW EXACTLY WHAT WAS GOING ON - EVIDENTLY THIS IS QUITE THE COMMON THING WITH THESE TRUCKS AND OTHERS - AND TOLD ME THAT I WOULD HAVE TO HAVE THE ENTIRE INSTRUMENT PANEL REPLACED. PRICING AROUND $375 FOR THE PART AND ANOTHER $100 OR SO FOR INSTALLATION. I HAVE INVESTIGATED COMPLAINTS ON THE INTERNET FOR THIS PROBLEM, WITH GM VEHICLES, AND THERE ARE FAR TOO NUMEROUS OUT THERE FOR THIS TO BE A SINGLE INCIDENT. IT IS OBVIOUS THAT THIS IS A DEFECT. IN MY OPINION, GM SHOULD BE RESPONSIBLE FOR THE REPAIR WITH A RECALL. I CAN SEE WHERE IT WOULD DEFINITELY CAUSE ALARM AS FAR AS A SAFETY CONCERN. FORTUNATELY I HAVE NOT HAD AN INCIDENT YET, BUT DEFINITELY FEEL THAT THIS SHOULD BE LOOKED INTO FURTHER. I JUST WANTED TO NOTE THAT I ALSO SAW ON AN INTERNET WEBSITE FOR LAWYERS THAT THEY ARE GATHERING COMPLAINTS TOGETHER FOR A CLASS ACTION SUIT AGAINST GM. I THOUGHT IT WOULD BE BETTER TO REPORT THIS FOR INVESTIGATION FIRST. *JB

DT*: THE CONTACT STATED WHILE DRIVING VARIOUS SPEEDS OR IDLING, THE SPEEDOMETER READING WAS INCORRECT. THE SPEEDOMETER READ ZERO INTERMITTENTLY WHILE DRIVING, OR IT READ ONE HUNDRED MILES PER HOUR WHILE SITTING STILL. THE VEHICLE WAS DRIVEN TO THE DEALER, WHO DETERMINED THE ELECTRONICS OF THE SPEEDOMETER NEEDED TO BE REPLACED. *AK UPDATED 12/15/2006 - *NM

I HAVE A 2004 GMC YUKON. THE SPEEDOMETER IS MALFUNCTIONING ,IT DISPLAYS INCORRECT ERRATIC SPEEDS, MAXING OUT AT 40 MPH NO MATTER HOW FAST I AM DRIVING. RECENTLY ON A LOCAL FREEWAY I ALMOST HAD A ACCIDENT WHEN THE TRAFFIC SLOWED AHEAD AND I THOUGHT I WAS GOING 30 MPH BUT MY ACTUAL SPEED WAS ABOUT 65. IT NEARLY KILLED ME. I HAVE CONTACTED GMC BUT HAVE NOT HAD ANSWER TO THIS PROBLEM.

MY 2004 GMC YUKON STARTED HAVING SPEEDOMETER TROUBLES A FEW MONTHS AGO. SOMETIMES IT WOULD WORK JUST FINE, BUT SOMETIMES IT WOULD READ 120 MPH WHEN I WAS PARKED, OR SOMETIMES IT WOULD READ 0 MPH WHEN I WAS GOING ABOUT 65 ON THE HIGHWAY. SOME DAYS IT WOULD WORK JUST FINE, OTHER DAYS, IT WAS VERY OFF. IT GOT TO WHERE I COULD NOT RELY ON MY SPEEDOMETER TO TELL HOW FAST I WAS GOING. I HAD TO USE A GPS TO GET MY SPEED. *NM

"STABILITY SYSTEM DISABLED" WAS DISPLAYED PRIOR TO THE BRAKES BEING ENGAGED WITHOUT DRIVER INPUT. THE VEHICLE WAS TAKEN TO THE DEALER AND A 'YAW SENSOR' REPLACED. THE PROBLEM RETURNED WITHIN 20 MILES. A SECOND SENSOR WAS REPLACED ALONG WITH REPROGRAMMING. THE PROBLEM CONTINUES. DEALER STATES "GM HAS TOLD US TO DO NOTHING MORE". NO FURTHER EXPLANATION IS OFFERED BY THE DEALER OR GM "CUSTOMER ASSISTANCE". I BELIEVE THAT A VEHICLE THAT ACTIVATES BRAKES ON DRY PAVEMENT WITHOUT THE DRIVER'S FOOT ON THE PEDAL IS DANGEROUS.

2004 GMC YUKON SLT -- INSTRUMENT PANEL WHEN TRUCK WAS STARTED. ALL GAUGES (FUEL, BATTERY & WATER) BECAME INACTIVE. SHIFT INDICATOR NO LONGER WORKED AND I WAS UNABLE TO DETERMINE WHAT GEAR THE CAR WAS IN. AUDIO SYSTEM (CASSETTE, CD PLAYER AND RADIO) BECAME INOPERABLE. CAR TAKEN TO DEALERSHIP -- BECK & MASTEN NORTH IN HOUSTON. I WAS TOLD THAT THE BODY CONTROL MODULE WAS DEFECTIVE AND WOULD NEED TO BE REPLACED. PREVIOUS ISSUE WITH THE INSTRUMENT PANEL CLUSTER GOING OUT, CAUSING SPEEDOMETER TO BECOME INOPERATIVE. DEALER ADMITTED THAT THIS WAS A PROBLEM ON A NUMBER OF YUKONS. (I HAVEN'T SEEN THIS A A RECALL ON EITHER YOUR SITE OR GMC'S SITE.) GMC HAS VIOLATED FMVSS STANDARD NO. 101 AND PARTS 573 AND 577.
