2005 GMC ENVOY Complaints

SPEEDOMETER STUCK AT 60MPH WHILE TRAVELING. DIDN'T MATTER IF STOPPED, ACCELERATING, DECELERATING, OR TURNING VEHICLE OFF. TURNING OFF THE CAR AND RESTARTING IT SEEMED TO CAUSE THE SPEEDOMETER TO DECREASE, SOME, FINALLY GETTING IT TO REGISTER 20MPH. UPON RESTARTING THE VEHICLE IN THE MORNING THE SPEEDOMETER STILL REGISTERED 20 MPH AND UPON ACCELERATION THE SPEEDOMETER FLUCTUATED FINALLY SETTLING AT 80MPH. WE WERE UNABLE TO TELL HOW FAST WE REALLY ARE TRAVELING BECAUSE THE SPEEDOMETER IS WACKO. STOPPING AND TURNING OFF THE VEHICLE DOES NOT HELP. THE SPEEDOMETER DOES NOT RESET TO ZERO IT IS NOW STUCK AT 80MPH. OUR LOCAL GM DEALER ADVISED THAT NO RECALL HAS BEEN ISSUED BUT AN EXTENDED WARRANTY TO 75,000 MILES WAS OFFERED ON THE VEHICLE FOR THIS PARTICULAR PROBLEM. OUR VEHICLE IS OVER THE MILEAGE FOR THE WARRANTY. GM IS AWARE THERE IS A PROBLEM WITH WACKO SPEEDOMETERS HENCE THE WARRANTY EXTENSION. ONE WOULD ASSUME BEING ABLE TO MONITOR ONES SPEED IN A VEHICLE IS AN IMPORTANT SAFETY CONCERN. *TR

FUEL GAUGE PROBLEMS....MY FUEL GAUGE HAS BEEN FLOATING FROM 1/2 A TANK TO EMPTY FOR THE PAST FEW WEEKS AND NOW IT THE FUEL LIGHT JUST STAYS ON EVEN WHEN THERE IS GAS IN THE CAR. AFTER RUNNING FOR A WHILE THE GAUGE WILL SAY THERE IS GAS AND THEN IT WILL GO BACK DOWN TO EMPTY. *TR

THE FUEL TANK LEVEL SENSOR IS DEFECTIVE AND COULD RESULT IN A SUBJECT VEHICLE RUNNING OUT OF FUEL, STALL, AND BEING REAR ENDED BY ANOTHER VEHICLE. THE FUEL LEVEL SENDING UNIT HAS A VARIABLE RESISTOR ATTACHED TO A FLOAT INSIDE THE FUEL TANK. AS YOU USE FUEL, THE FLOAT CHANGES POSITION (DOWNWARDS) CAUSING THE VARIABLE RESISTOR TO CHANGE VALUE. THE CHANGE IN RESISTANCE CAUSES A CHANGE IN THE VOLTAGE SENT TO THE FUEL GAGE. MY P0463 ERROR IS SAYING THAT THE VARIABLE RESISTOR IS SHOWING HIGH INPUT, INSTEAD OF A TYPICAL SMALL VALUE. THIS MEANS THAT THE VARIABLE RESISTOR OR SOMETHING ELSE INSIDE THE SENDER UNIT IS CAUSING THE ECM TO "SEE" AN INVALID VOLTAGE ON THE FUEL GAGE CIRCUIT. IF THE VOLTAGE IS TOO HIGH THEN THE RESISTANCE IS TOO HIGH. POSSIBLY A BAD CONNECTION BETWEEN THE ECU AND THE SENDER OR A GROUNDING PROBLEM.

DRIVING DOWN ROAD AND SUDDEN LOSS OF POWER CHECK ENGINE ON AND REDUCED ENGINE POWER LIGHT ON.. CAR SPED UP FAST AND THEN DROPPED DOWN TO NO SPEED DROVE 5 MPH TO GET HOME. *TR

FUEL PUMP NOT READING GASOLINE LEVELS CAUSING THE GAUGE IN THE DASH NOT TO WORK AND BE ON EMPTY AT ALL TIMES. FUEL LIGHT ALSO STAYS ON. *TR

MY 2005 GMC ENVOY XL FUEL GAUGE IS NOT WORKING. AT 1/4 TANK, I FILLED UP THE TANK, STARTED THE ENGINE AND THE FUEL NEEDLE WENT PAST EMPTY AND LIGHT CAME ON. AFTER MANY RE-STARTS, DAYS THE GAUGE IS STILL NOT WORKING CORRECTLY. AS I DRIVE NOW WITH A FULL TANK THE GAUGE NEEDLE CONTINUES TO SLOWLY GO UP AND GO DOWN WITH DRIVING. *TR

I OWN A 2005 GMC ENVOY THAT IS HAVING A KNOWN PROBLEM WITH THE GAS GAUGE AND THE SENDER UNIT. THE CHECK ENGINE LIGHT ALSO COMES ON. APPARENTLY NUMEROUS CUSTOMERS HAVE BEEN EXPERIENCING THIS SAME ISSUE ON THEIR GM SUVS. THERE SHOULD BE A RECALL TO FIX THESE KNOWN MANUFACTURER FAULTY WORKMANSHIP ISSUES. *TR

I'M HAVING THE SAME ISSUE WITH THE FUEL GAUGE ON MY 2005 GMC ENVOY. I CAN REGISTER 1/4 A TANK BUT THE MINUTE I FILL, THE GAUGE DROPS BELOW EMPTY AND THE FUEL LIGHT COMES ON. I HAVE TO DRIVE AT LEAST 25 MILES TO HAVE IT REGISTER EVEN A 1/4 OF A TANK AND A FULL 70-85 MILES FOR THE GAUGE TO GET TO SHOW A MORE ACCURATE LEVEL. THE MECHANIC I WENT TO ADMITTED IT WAS THE FUEL LEVEL SENSOR CAUSING THE ISSUE BUT ADVISED ME THAT I HAD TO REPLACE THE ENTIRE FUEL PUMP. HE QUOTED $505 FOR THE FUEL PUMP AND AN ADDITIONAL $360 FOR THE LABOR ITS NOT FIXED I DON'T HAVE THE MONEY, WHAT HAPPENS IF I RUN OUT OF FUEL ON THE HIGHWAY OR ON A TIGHT TURN ON A HILL AND THE CAR SHUTS DOWN AND THE STEERING LOCKS? I'VE READ 1000'S OF COMPLAINTS AND HORROR STORIES ABOUT THIS AND NO RECALL. THIS IS EXTREMELY DANGEROUS! *TR

DEFECTIVE GAS GAUGE IN 2005 ENVOY, ONLY HAS 56,000 MILES ON IT. GAUGE BOUNCES ERRATICALLY, AND EVEN AFTER FILLING UP THE TANK THE GAUGE SHOWS EMPTY. PROBLEM JUST STARTED LAST WEEK AND NOW HAPPENS DAILY - THERE IS NO RELIABLE WAY TO TELL HOW MUCH GAS I ACTUALLY HAVE. NOTHING HAS BEEN DONE TO CORRECT THE PROBLEM, BUT I NOTICED ON THE INTERNET THAT THIS IS A WIDE-SPREAD PROBLEM FOR THIS VEHICLE. *TR

ONE DAY I FILLED UP MY GAS GAGE AND IT READ EMPTY WHEN I DROVE AWAY. IT HAS READ EMPTY EVER SINCE WITH THE EXCEPTION OF MOVING SLIGHTLY ABOVE E FOR A FEW MIN SHORTLY AFTER FILLING TANK. THIS HAPPENED IN FEB 07 AND I JUST HAVE NOT HAD THE MONEY TO DROP ON A GAS GAGE SO I CALCULATE MY MILES WHICH IS EXTREMELY INCONVENIENT AND I HAVE RUN OUT OF GAS ON SEVERAL OCCASIONS. *TR
