2004 GMC ENVOY Complaints

SPEEDOMETER ON MY 2004 GMC ENVOY XL SLT READS INCORRECTLY AT ALL TIMES. BEGAN AS READING HIGH OCCASIONALLY, NOW IT IS ENTIRELY UNRELIABLE. SOMETIMES HIGH, SOMETIMES LOW, SOMETIMES 140MPH IN THE DRIVEWAY. *TR

THE SPEEDOMETER/TACHOMETER IN MY 2004 GMC ENVOY READ INACCURATELY. THE NEEDLES READ WAY OFF OF WHERE THEY SHOULD BE (IE. READING 45 MPH AT IDLE AND TACH AT 8,000 RPMS AT IDLE). *TR

SPEEDOMETER IS ERRATIC OFTEN 30 TO 80 MPH OFF AND WILL NOT RETURN TO 0 MPH WHEN STOPPED. CURRENTLY IT READS ABOVE 120 MPH AND WILL NOT MOVE UP OR DOWN. *TR

ON 11/01/07 I NOTICED THE SPEEDOMETER ACTING ERRATIC; IT WOULD STAY ON 10 TO 20 MPH. WHEN I KNEW I WAS GOING FASTER. AT OTHER TIMES IT WOULD CREEP UP TO 75 OR 80 MPH. AND NOT GO DOWN WHEN I SLOW DOWN. OCCASIONALLY IT WOULD WORK FINE. THIS WENT ON ABOUT 3 WEEKS AND I THOUGHT IT MIGHT CORRECT ITSELF. IT FINALLY STOPPED WORKING ALTOGETHER COMING TO REST ABOVE 120 MPH. ON 12/07/07 I TOOK MY VEHICLE TO THE DEALERSHIP. THEY SAID THEY WOULD HAVE TO REPLACE THE WHOLE INTERMENT PANEL AT A COST OF AROUND $470.00. THEY ALSO SAID IF I DIDN'T HAVE OVER 60,000 MILES ON MY CAR IT WOULD HAVE BEEN COVERED UNDER THE WARRANTY. I HAD 62,492 MILES ON THE DAY I TOOK THE CAR TO THE DEALER. *TR

I HAVE A 2004 GMC ENVOY XUV AND WHEN THE OIL WAS JUST RECENTLY CHANGED THE MECHANIC NOTICED THAT THE GAS TANK WAS LEAKING AT THE POINT WHERE THE FILLER MET THE MAIN BODY OF THE TANK. HE SAID SINCE THE TANK WAS PLASTIC THE GAS WAS CAUSING THE DETERIORATION AND THE ENTIRE TANK WOULD CAUSE A MAJOR ISSUE. AFTER CHECKING WITH OUR LOCAL GMC DEALER I DISCOVERED THAT THE VEHICLE IS JUST OUT OF THE 3 YR WARRANTY PERIOD AND SINCE IT WAS PURCHASED IN ARIZONA AND NOT CALIFORNIA IT IS NOT COVERED UNDER THE EXTENDED GMC WARRANTY. THIS SHOULD NOT BE PART OF A REPLACEMENT PLAN THE CONSUMER SHOULD BE PAYING FOR, NOT LIKE A REGULAR MAINTENANCE ITEM (CHANGING TIRES, OIL CHANGES, SPARK PLUGS, ETC.) CUTTING CORNERS TO MAKE THE VEHICLE LIGHTER AND THEN NOT SUPPORTING THE CHANGE IS NOT THE BEST WAY TO BE POPULAR. *TR

2004 GMC ENVOY FUEL PUMP MODULE FLANGE CORROSION, CAUSING LEAK ONTO TOP OF GAS TANK AND EXHAUST. *TR

1. I PURCHASED A 2004 ENVOY. THE DEALER I PURCHASED IT FROM HAD IT UNDER WARRANTY. 2 WEEKS AFTER I PURCHASED, THE INTERIOR LIGHTS WERE COMING ON AND OFF, THE AUTOMATIC DOOR LOCKS STARTED TO LOCK BY THEMSELVES SIMULTANEOUSLY. NON STOP. IT SCARES MY CHILDREN, AS WELL AS I, BECAUSE I DON'T KNOW IF IT'S GOING TO SPARK A FIRE OR WHAT. SOMETIMES IT DOES IT MORE THAN OTHERS, FOR EXAMPLE, WHEN IT RAINS, BUT IT ONLY DOES IT WHEN I ROLL THE DRIVER'S SIDE WINDOW UP. EVEN IF ITS NOT DOWN AND I ROLL IT UP IT DOES IT. AS WELL AS IF I HIT A SMALL POT HOLE AND SOMETIMES IT JUST DOES IT ON ITS ON. I'VE TAKEN IT TO A GMC DEALER 4 OR MORE TIMES AND THEY CAN'T FIND THE PROBLEM ANY WHERE. SO, NOTHING HAS BEEN DONE TO FIX THIS PROBLEM BECAUSE NO ONE CAN FIND A SOLUTION. I PARK MY $18,000 VEHICLE NEXT TO THE ROAD IN CASE IT DOES SPARK A FIRE. PLEASE INFORM ME IF ANYTHING IS AVAILABLE OR WHO I NEED TO CONTACT AT GMC TO FIND AN ANSWER. *TR

SINCE CAR IS NEW WE CONTINUE TO HAVE MELTING ISSUE WITH WIRING AND HARNESS BEHIND RADIO RACK AND AREAS THAT ARE AFFECTED IN THIS INSTRUMENT CLUSTER. THIS HAS HAPPENED SO MANY TIMES GMC HAS EXTENDED THE WARRANTY ON CAR TO COVER ALL OF THE CAR. IT IS AGAIN CAUSING A PROBLEM, LIGHTS OUT ON CLUSTER, LIGHTER INOP, HEATER AND A/C FANS NOT ALWAYS WORKING. *TR

CHECK ENGINE LIGHT ON AND TAKEN TO ADVANCE AUTO PARTS WAS TOLD THAT THERE WAS A SMALL LEAK. THEY ADVISED THAT HOSES ARE TO BE CHECKED. HOSES WERE CHECKED AND CHECK ENGINE LIGHT REMAINED ON. TAKEN TO THE DEALER AND FOUND OUT THAT THERE IS A LEAK IN THE FUEL TANK. WAS TOLD THAT THIS WAS NOT A RECALL ITEM. BUT THIS IS A VERY DANGEROUS DEFECT. NOW WAITING FOR PART TO BE REPLACED. *TR

I JUST BOUGHT A USED 04 GMC ENVOY WITH 30,000 MILES ON IT. NOW ABOUT A MONTH AFTER I BOUGHT IT I'M HAVING PROBLEMS WITH THE SPEEDOMETER. SOMETIMES IT WORKS SOMETIMES IT DOESN'T. WHEN IT DOES NOT WORK IT READS TO HIGH OR TWO LOW. I CAN BE DRIVING DOWN THE ROAD AT 65 AND IT WILL DROP BELOW 0. OR I CAN BE STOPPED AT A LIGHT AND IT SHOWS 40. A QUICK SEARCH ON THE WEB SHOWS THOUSANDS OF PEOPLE WITH THE SAME PROBLEM. I FEEL GM AND GMC SHOULD HAVE TO DO A RECALL ON THIS AS IT COULD BE A LIFE AND SAFETY ITEM. FOR EXAMPLE ONE COULD SLOW TO THE RECOMMEND SPEED FOR A CURVE OR A TURN. IF THE SPEEDOMETER IS READING TWO LOW THEN THE PERSON WOULD BE TRAVELING TWO FAST FOR THE TURN. I SEE ALSO WHERE A CLASS ACTION LAW SUIT IS IN THE WORKS ON THIS. *TR
