2004 GMC Envoy Xuv

SPEEDOMETER STARTED SHOWING I WAS GOING 90-130MPH WHEN I WAS ON PROBABLY MOVING 50MPH. IT WAS ABOUT 30-50MPH OFF. WHEN CAR IS OFF SPEEDOMETER SHOWS 50MPH. FOUND OUT YOU CAN MAKE SPEEDOMETER DROP 5MPH AT A TIME IF YOU TURN THE CAR ON & OFF ABOUT 20 TIMES IT WILL EVENTUALLY GO TO ZERO MPH. AFTER A FEW DAYS IT DOES THE SAME ERRATIC BEHAVIOR. I HAVE READ OVER HUNDREDS OF POST ONLINE ABOUT THIS ON THIS MAKE AND MODEL ALONE AND THINK THIS IS A VERY BIG SAFETY CONCERN. I NEED HELP AND NEED MY CAR FIXED PLEASE HELP. *TR

CAR LURCHED FORWARD AND ENGINE SPEEDED UP WHEN PULLING INTO MY DRIVEWAY AT HOME. MOST OF MY DASHBOARD GAUGES HAVE BEEN FAILING OVER THE LAST YEAR INCLUDING THE SPEEDOMETER. I WAS USING THE CRUISE CONTROL PRIOR TO THE EVENT. I THINK IT MAY BE RELATED TO THE COMPUTER. I WAS ABLE TO STOP THE CAR BY TURNING OFF THE ENGINE. THE BRAKES WOULD NOT STOP THE CAR. THE DEALER HAS ADVISE ME THAT THEY KNOW ABOUT THE INSTRUMENT PANEL FAILING BUT NO RECALL HAS BEEN ISSUED. *TR

2004 GMC ENVOY XUV W/76K MILES; SPEEDOMETER IS ERRATIC. SHOWS NO SPEEDS SOMETIMES OR SHOWS SLOW SPEED SOMETIMES OR SHOWS EXCESSIVE SPEED SOMETIMES. DEALER INDICATED GMC YUKONS, FULL SIZE GMC PICKUP AND CADILLAC SUV'S WERE RECALLED FOR DEFECTIVE SPEEDOMETERS.. DEALER STATED NOT ENOUGH REPORTED SPEEDOMETER PROBLEMS WITH ENVOY XUV'S TO WARRANT A SAFETY RECALL. HOW MANY DEFECTIVE SPEEDOMETERS ARE REQUIRED TO WARRANT A SAFETY RECALL? *TR

SPEEDOMETER FAILED AT 44,000 MILES. GAS GAUGE MISREADS. INSTRUMENT CLUSTER IS BEING REPLACE BY GMC ON OTHER MODELS WITH THE SAME CLUSTER BUT THEY DECIDED NOT TO REPLACE THE ENVOYS CLUSTER. GMC KNOWS THAT THEY HAVE CLUSTERS THAT FAIL AND HAVE EVEN BEEN MONETARY REIMBURSEMENT BY OTHER COMPANIES TO REPLACE BUT STILL DO NOT REPLACE FOR THE ENVOYS. *TR

IN THE PROCESS OF MAKING A LEFT TURN, (DEAD END - NO ONCOMING TRAFFIC) THE VEHICLE FAILED TO GET UP TO SPEED AFTER DEPRESSING THE ACCELERATOR IN ORDER TO MAKE THE TURN. A WARNING LIGHT CAME ON THAT HAD NEVER BEEN SEEN BEFORE; IT WAS THE "REDUCED ENGINE POWER" LIGHT ALONG WITH THE "SERVICE ENGINE SOON" LIGHT. THE WAY WAS CLEAR TO PUT THE VEHICLE IN REVERSE AND BACK INTO A GAS STATION. A PRAYER WAS SAID BEFORE CONTINUING ON TO THE DESTINATION AT HAND WITH A TRIP TO THE DEALERSHIP IN THE AM. THE VEHICLE WAS TESTED AT THE DEALERSHIP WITH THE "FOUND CODE" P1680..GAS PEDAL SHORTING OUT. PEDAL WAS REPLACED, RETESTED, AND APPROVED WITHOUT A RECURRENCE OF THE CODE. TWO MONTHS HAVE PASSED WITHOUT A RECURRENCE SO FAR. THE TOTAL COST WAS $191.85. THANK GOD IT DIDN'T COST A LIFE! THE OLD PART IS AVAILABLE; TELEFLEX 15187573 G03302 2 360-133143 PASSED MADE IN MEXICO 400421 COULD NOT ALLOW THIS TO HAPPEN AGAIN OR TO OTHERS; REPAIRED IMMEDIATELY DUE TO DANGEROUS TO FATAL CONSEQUENCES IF TURNING LEFT IN FRONT OF AN ONCOMING SEMI. THIS COMPLAINT IS TO INFORM OTHERS OF A POTENTIALLY DANGEROUS SITUATION REGARDING THEIR GAS PEDAL. *TR

THE CONTACT OWNS A 2004 GMC ENVOY. THE CONTACT STATED THAT THE SPEEDOMETER SUDDENLY STOPPED WORKING. CONTACTED DEALER ABOUT ISSUE AND TOLD INSTRUMENT CLUSTER NEEDED TO BE REPAIRED. THE DEALER ALSO STATED THAT THEY WOULD NOT BE RESPONSIBLE FOR THE REPAIRS. THROUGH ONLINE RESEARCH, THE CONTACT DISCOVERED THAT NUMEROUS PEOPLE WERE EXPERIENCING THE SAME FAILURE AND GM SEPT 2007 TSB 07187 INCLUDED ENVOY BUT LATEST REVISIONS B & C AT DEALERS DOES NOT INCLUDE ENVOY. THE VEHICLE HAS NOT YET BEEN REPAIRED; HOWEVER, THE CONTACT BELIEVES THAT THE FAILURE WAS DUE TO A MANUFACTURER DEFECT AND A RECALL SHOULD BE ISSUED. THE VEHICLE HAS ONLY 20,000 MILES AND SEE THIS LACK OF GMC OWNING UP TO ITS ISSUE IS A HUGE SAFETY PROBLEM. *TR
