Owner report 10410408 · 2011-07-04 (July 4, 2011)

FUEL GAUGE IS NOT WORKING PROPERLY ON MY VEHICLE. IT STAYS ON "E" WHEN THERE IS PLENTY OF GASOLINE IN THE CAR. THERE HAVE BEEN SEVERAL COMPLAINTS ABOUT THIS THAT I HAVE SEEN ON WEBSITES. OCCASIONALLY THE GAUGE WILL MOVE UP BUT THEN GO BACK TO "E". I WENT TO DEALER AND THEY SAID IT IS A BAD FUEL SENOR GAUGE WHICH IS IN THE GASOLINE TANK. SEEMS LIKE THIS IS A COMMON ISSUE AND COULD CAUSE OTHER PROBLEMS. THE FUEL GAUGE HAS BEEN LIKE THAT FOR OVER 6 MONTHS, AS THE COST WAS ASTRONOMICAL AND I BELIEVE THERE SHOULD BE A RECALL. ADDITIONALLY,…

I BOUGHT A USED 2006 GMC ENVOY DENALI WITH 69,000 MILES IN JUNE 2010, BY JULY I WAS REPLACING THE AIR SHOCKS ON THE RIGHT SIDE OF THE VEHICLE. ON ABOUT 7/28/2011 ON THE BELTWAY WHERE THE SPEED LIMIT IS 65 I WAS IN THE FAR LEFT LANE APPROACHING A LEFT HAND EXIT WHEN MY CAR STALLED, I HAD RUN OUT OF GAS WITH NO INDICATION. I WAITED OVER AN HOUR FOR SOMEONE TO COME PUT GAS IN MY TRUCK IN ABOUT 100 DEGREE TEMPATURE. I LATER RAN OUT OF GAS ON A BACK ROAD COMING TO MY HOUSE AT NIGHT. AGAIN NO INDICATOR LIGHT CAME ON TO LET ME KNOW I WAS LOW ON GAS. N…

Owner report 10402478 · 2011-05-23 (May 23, 2011)

THE PROBLEM IS WITH MY 2006 GMC ENVOY DENALI EDITION. ABOUT JANUARY 1, 2011 I RECEIVED GAS AT A SHELL GAS STATION. AFTER RECEIVING FUEL THE FUEL GAUGE REMAINED AT E AND DID NOT G TO F SIGNALING A FUEL TANK. EVERY TIME I REFILL THE TANK THE GAS NEEDLE SWINGS BACK AND FORTH BETWEEN F AND E. AROUND HALF A TANK THE NEEDLE DROPS TO E. THE FUEL GAUGE IS NOT READING ACCURATELY AND HAS CAUSED THE TRUCK TO STALL ONCE WHILE DRIVING. THE CHECK ENGINE LIGHT IS CONSTANTLY ON. I HAVE NOT DONE ANY REPAIRS BECAUSE I'VE BEEN TOLD THE FUEL ASSEMBLY HAS TO…

Owner report 10187958 · 2007-04-10 (April 10, 2007)

TL*- THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THERE WAS A VIBRATION IN THE VEHICLE WHEN THE GAS PEDAL WAS APPLIED WHILE TRAVELING BETWEEN 30 AND 40 MPH. THE VEHICLE WOULD ALSO VIBRATE AT ANY SPEED. IT FELT AND SOUNDED AS IF IT NEEDED TO SHIFT GEARS, AS IN A MANUAL VEHICLE, BUT WAS IN THE WRONG GEAR. IT WAS INVOLVED IN A CRASH IN NOVEMBER 2006. TWO DEALERS STATED THAT THERE WAS A TECHNICAL SERVICE BULLETIN THAT REFERENCED THE FAILURE, BUT THERE WAS NOTHING THEY COULD DO TO CORRECT IT. WHEN ENGAGING THE BRAKE THE VEHICLE WOULD MOVE FORWARD…

FUEL SENSOR FAILURE IN THE GAS TANK. CAUSING THE FUEL TANK TO READ EMPTY WHEN FULL, CAUSING THE SUV TO STALL WHEN THE TANK IS FULL, CAUSING THE CHECK ENGINE LIGHT TO COME ONE. THIS IS A SAFETY ISSUE. *KB

Owner report 10493613 · 2013-01-21 (January 21, 2013)

DRIVING AROUND A CORNER, WHEELS LOCKED UP, SERVICE STABILITRACK LIGHT WENT ON, STEERING WHEEL UNRESPONSIVE TO TURNING. WENT TO A SHOPPING CENTER AND WAS UNABLE TO GET OUT OF PARKING SPACE AS WHEELS LOCKED UP AND VEHICLE WOULDN'T TURN. THIS SHOULD BE A RECALL. THE SERVICE STABILITRACK LIGHT ON DASH CAN GO ON AT ANYTIME WHILE DRIVING. THIS CAN BE DANGEROUS WHEN TRYING TO TURN ON A BUSY STREET AND NOTHING HAPPENS. IT FEELS LIKE THE CAR IS NOT RESPONSIVE TO THE STEERING WHEEL, BRAKES AND WHEELS. *TR

2006 GMC ENVOY DENALI PURCHASED 12/05. BEGINNING AT ABOUT 10,000 MILES THE TRANSMISSION WOULD SHIFT ABRUPTLY INTO 1ST GEAR AFTER THE CAR HAD STOPPED MOVING. THIS DOES NOT HAPPEN EVERY TIME BUT WHEN IT DOES IT FEELS AS IF THE CAR HAS BEEN HIT FROM BEHIND. DEALER HAS NOT BEEN ABLE TO DUPLICATE THE PROBLEM BUT STATES THAT OTHER OWNERS HAVE REPORTED THE SAME PROBLEM. *TR
