2004 GMC ENVOY Complaints

I PURCHASED MY 2004 ENVOY XUV NEW. I LOVE IT, BUT THE SPEEDOMETER HAS BEEN GETTING PROGRESSIVELY WORSE. I GUESS I'VE BEEN ONE OF THE LUCKY ONES. THE BRAKES ARE FINE AND EVERYTHING ELSE SEEM TO BE OK SO FAR. I CURRENTLY HAVE 89,000 MILES ON IT AND THE FREQUENCY OF THE SPEEDO ACTING UP ARE GETTING MORE COMMON. I REMEMBER THE FIRST TIME WAS LATE IN '07. THE SPEEDO JUST KEPT CLIMBING HIGHER AND HIGHER TILL IT WAS PINNED. AND STAYED THERE FOR A DAY OR TWO. IT WOULD READ 120 MPH PARKED IN THE GARAGE. I BROUGHT IT IN AND THE DEALER JUST ROLLED THEIR EYES AND SAID THEY COULD ORDER ANOTHER DASH BOARD FOR AROUND $500.00, BUT I OPTED NOT TO FIX IT AT THAT TIME. THE DEALER TOLD ME IT WAS A COMMON THING WITH THE ENVOY, BUT GM HAS NO RECALLS ON IT. IT HAD SEEMED FINE FOR A WHILE. THEN IT HAPPENED AGAIN A FEW TIMES IN '08. NOW IT'S ONLY MARCH OF '09 AND IT HAS HAPPENED AT LEAST ONCE EVERY TWO WEEKS. IT IS CLEARLY OUT OF WARRANTY BUT BEING A SAFETY ITEM SUCH AS A INSTRUMENT CLUSTER ONE WOULD THINK IT WOULD BE A RECALL ITEM. THIS APPEARS TO BE A NATION WIDE ISSUE AND GM AND THE DOT / NHTSA DO NOT RECOGNIZE IT? I LIKE THE VEHICLE, I AM HAPPY WITH IT OTHERWISE. JUST DISAPPOINTED AND FRUSTRATED WITH THE NHTSA AND GM. *TR

INVESTIGATED CHECK ENGINE LIGHT. SECONDARY AIR INJECTION PUMP FAILURE FOR EMISSIONS. *TR

PROBLEM STARTED OUT AS ERRATIC READING WITH SPEEDOMETER. AFTER APPROX. 5 DAYS SPEEDO FINALLY WOULDN'T REGISTER AT ALL TOOK VEHICLE TO AUTHORIZED DEALER TO BE REPAIRED - $555.00 CHARGE TO REPLACE INSTRUMENT PANEL AND REPROGRAM. CALLED GM FOR FINANCIAL HELP AS I NOTICED THERE WERE ALOT OF FAILURES WITH GMC SUV'S AND PICK-UP TRUCKS. GM WOULD NOT ACKNOWLEDGE THERE WAS A PROBLEM WHICH I FEEL IS TOTALLY DISINGENUOUS. SPEEDOMETER IS NECESSARY TO BE WORKING AS A SAFETY ISSUE. BECAUSE I WAS OUT OF STATE AT THE TIME OF PART BREAKDOWN I FELT I HAD NO CHOICE BUT TO HAVE PROBLEM FIXED BEFORE MY RETURN TRIP HOME (1250 MILES). JUDGING HOW MANY OTHER ENVOYS HAVE HAD SAME PROBLEM, I FEEL GM IS DODGING THEIR RESPONSIBILITY I NOTICED THAT THERE HAS BEEN CLASS-ACTIONS AGAINST THEM FOR THE SAME PROBLEM. *TR

THE TACHOMETER WOULD QUIT WORKING BUT IT HAPPENED ONLY A COUPLE OF TIMES IN JAN 2008 & AGAIN IN JUNE 2008 AND WHEN WE TURNED THE CAR OFF AND STARTED IT THE NEXT TIME IT SEEMED TO BE FINE AS IF IT NEEDED RESET. IN JAN OF 2009 THE SPEEDOMETER BEGAN TO FAIL AT FIRST OCCASIONALLY THEN ALL THE TIME AT THE SAME TIME THE TACHOMETER SPORADICALLY FAILED. SO WE TOOK IT TO THE DEALERSHIP AND HAD THEM REPLACE THE INSTRUMENT CLUSTER IN THE DASH (THEY KEPT THE OLD PART) AND GM REFUSED TO HELP WITH THE PROBLEM SITTING THE MILEAGE ON THE VEHICLE AT THE TIME OF THE REPAIR. *TR

THE SPEEDOMETER GRADUALLY DECREASED FROM INTERSTATE SPEED (70MPH) TO 0 MPH WHILE DRIVING. SPEEDOMETER FAILS TO OPERATE. I PERSONALLY KNOW 2 PEOPLE WHO HAVE HAD THIS HAPPEN ON A 2004 ENVOY. *TR

THE SPEEDOMETER QUIT WORKING CORRECTLY, WHEN I FIRST NOTICED IT MY SPEEDOMETER SAID I WAS GOING 120MPH AND I WAS IN TOWN IN A 35MPH ZONE. I HAD MY GPS DEVICE ON AND IT SHOWED THAT I WAS ACTUALLY GOING 35MPH. AFTER STOPPING AT A STOP LIGHT THE SPEEDOMETER STATED THAT I WAS STILL TRAVELING AT A SPEED OF 75 MPH, AND THAT WAS INCORRECT BECAUSE I WAS SITTING STILL AT THE LIGHT. ALSO, AFTER TURNING OFF THE VEHICLE IT STILL REGISTERED A RATE OF SPEED OF 75 MPH. THERE ARE SOME DAYS THAT THE SPEEDOMETER WORKS FOR A WHILE AND THEN IT GOES CRAZY. ANOTHER EXAMPLE, IT SOMETIMES SHOWS THAT I AM GOING AT A RATE OF SPEED OF 0 MPH AND I KNOW THAT I AM AT LEAST GOING 55 MPH. THIS IS COMPLETELY UNSAFE. UPON CONTACTING THE GM SERVICE CENTER THEY STATED THEY THOUGHT IT MIGHT BE THE INSTRUMENT CLUSTER NEEDING REPLACED, BUT IF THAT WOULD BE THE CASE THE OTHER GAUGES WOULD NOT WORK PROPERLY. SO FAR THE ONLY THING THAT IS MESSED UP IS THE SPEEDOMETER. I HAVE NOT BEEN ABLE TO CORRECT THE FAILURE AS THE SERVICE CENTER TOLD ME OVER THE PHONE THAT IT WOULD COST ME AROUND $300.00 OR MORE AND THEY WANT TO REPLACE THE ENTIRE INSTRUMENT PANEL, WHICH IN MY OPINION DOES NOT NEED REPLACED....ONLY THE SPEEDOMETER NEEDS REPLACED/REPAIRED. *TR

THE SPEEDOMETER HAS A MALFUNCTION THAT WILL MAKE THE SPEEDOMETER READ VERY ERRATIC, AT A STEADY SPEED THE SPEEDOMETER HAS BEEN ALL THE WAY OVER TO THE 120 MPH AND ON OTHER DAYS IT WILL STAY A ZERO. THIS PROBLEM OCCURS FREQUENTLY, NOT EVERYDAY BUT I WOULD SAY ATLEAST ONCE EVERY 2 WEEKS. I BELIEVE THERE COULD BE GRAVE CONSEQUENCES., YOU HAVE ABSOLUTELY NO IDEA HOW FAST OR SLOW YOU ARE ACTUALLY GOING, ESPECIALLY IF THERE ARE NO CARS TRAVELING THE SAME DIRECTION AS YOU. I WILL ATTEMPT TO REPAIR THIS ITEM MYSELF SINCE THE DEALER SAYS IT CAN COST $300-$700 TO FIX. *TR

WHILE DRIVING ON A 5-6 HOUR TRIP, THE SPEEDOMETER BEGAN MALFUNCTIONING ABOUT 1/2 WAY THROUGH THE TRIP. WE HAD TO USE THE SPEEDOMETER ON THE TOMTOM TO DETERMINE OUR CORRECT SPEED SINCE THE SPEEDOMETER WAS READING 5-10 OVER THE SPEED LIMIT. AFTER THE VEHICLE SAT FOR THE NIGHT, IT STARTED WORKING AGAIN...BUT ONLY TO STOP AGAIN 1/2 WAY THROUGH OUR TRIP BACK HOME. I HAVE NOTICED THAT THIS HAS HAPPENED TO THE SPEEDOMETER ON MORE THAN ONE OCCASION AND REFUSE TO PAY THE OUTRAGEOUS AMOUNT TO REPAIR IT. I THINK THIS IS A MANUFACTURER DEFECT AND SHOULD BE TAKEN CARE OF BY THEM. *TR

THE SPEEDOMETER STOPPED WORKING PROPERLY. IT WOULD REGISTER AT ALL KINDS OF SPEED. THEN IT WILL STICK BELOW 120MPH. THIS IS AN EVERYDAY OCCURRENCE. IT IS NOW TO THE POINT THAT THE ODOMETER IS NOT WORKING PROPERLY. I HAVE HAD AN ESTIMATE DRAWN UP TO REPAIR/REPLACE AND IT WAS OVER 600 DOLLARS. I FEEL THAT WITH ALL OF THE OTHER COMPLAINTS LISTED ABOUT THE SAME ISSUE, GM SHOULD ISSUE A RECALL AND COVER THE COST FOR REPAIR, SINCE THIS IS A SAFETY ISSUE. *TR

THE TACH ON MY '04 ENVOY WITH 67K MILES STARTED ACTING ERRATIC AND HAS COMPLETELY FAILED JUST AS ALL THE OTHER SERVICE BULLETINS . THIS HAS CORRECTED ITSELF BUIS TILL ERRATIC. GM NEEDS TO ADDRESS THE FAULTY ELECTRONIC GAUGES ON THESE '04 ENVOYS. *TR
