2006 GMC ENVOY DENALI XL Complaints

ON MAY 3RD 2010, THE TRUCK JUST DIED IN THE MIDDLE OF THE ROAD WHILE DRIVING HOME WITH MY SON AT NIGHT. I HAD TO QUICKLY TRY TO GET TO THE SIDE OF THE ROAD WITHOUT ANY POWER ASSIST. THE ENVOY WOULD NOT START AGAIN, NOT EVEN TURN OVER. THE SHIFTER WAS LOCKED AND IT COULD NOT EVEN BE PUT INTO NEUTRAL TO PUSH IT OVER TO THE SIDE. VARIOUS MESSAGES SCROLLED BY ON THE VEHICLE DISPLAY AND MANY OF THE WARNING LIGHTS WERE DIMLY BLINKING. I HAD TO GET IT TOWED. I SCANNED THE FOLLOWING CODES P1516 & P1682, LOOKED UP THE SYMPTOMS ON THE INTERNET AND FOUND MANY HITS THAT SAID THE ISSUE WAS WITH A FAULTY IGNITION SWITCH. AFTER CHARGING UP THE BATTERY WHICH RAN DOWN ON THE HAZARDS WHILE WAITING AN HOUR FOR A TOW, I REPLACED THE IGNITION SWITCH AND THE ENVOY NOW WORKS AGAIN. IT HAS LESS THAN 30,000 MILES ON IT. THIS TYPE OF FAILURE CONCERNS ME VERY MUCH! I CONSIDER IT A HUGE SAFETY ISSUE THAT A VEHICLE CAN DIE WHILE DRIVING AND THEN BE SO COMPLETELY DISABLED BY A $30 PART. THIS COULD OF HAD MUCH MORE DIRE CONSEQUENCES HAD IT HAPPENED ON A FREEWAY AS OPPOSED TO A SUBURBAN SIDE STREET. *TR

GAS GAUGE FLUCTUATES MAKING IT IMPOSSIBLE TO KNOW THE AMOUNT OF GAS LEFT IN VEHICLE. VEHICLE HAS RUN OUT OF GAS ON HIGHWAY SEVERAL TIMES. GAS SENSOR IS FAULTY ACCORDING TO DEALER.

TL*THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THE CONTACT STATED THAT IN OCTOBER 2009, HE NOTICED THAT THE FUEL GAUGE WOULD "FLUTTER" AND REGISTER THAT IT WAS EMPTY WHEN HE ADDED GASOLINE TO THE FUEL TANK. AFTER CONSUMING FIVE TO SEVEN GALLONS OF FUEL, THE FUEL GAUGE WOULD BEGIN WORKING NORMAL UNTIL THE IT WAS TIME TO ADD THE MAXIMUM AMOUNT OF FUEL IN THE TANK. THE CHECK ENGINE LIGHT ALSO ILLUMINATED AND THE HEATER WOULD BLOW COLD AIR ON THE DRIVER SIDE AND HOT AIR ON THE PASSENGER SIDE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE SENDING UNIT IN THE FUEL TANK WAS REPLACED AND THE HEATER WAS REPROGRAMMED; HOWEVER, THE HEATER STILL DID NOT FUNCTION PROPERLY. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS APPROXIMATELY 40,000. THE CURRENT MILEAGE WAS APPROXIMATELY 46,000.

TL*THE CONTACT OWNS A 2006 GMC ENVOY DENALI XL. THE STABILITY TRACK LIGHT CAME ON AND THE ANTILOCK BRAKES ENGAGED WHEN THE VEHICLE REDUCED SPEED. THE VEHICLE WAS TAKEN TO THE DEALER PREVIOUSLY AND THEY REPROGRAMMED THE COMPUTER. THE FAILURE HAS RECURRED AND THE WARNING LIGHT ILLUMINATED AGAIN. THE DEALER DOES NOT KNOW WHY IT FAILED AGAIN. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 15,000.

I WAS DRIVING OUR 2006 GMC ENVOY DENALI AT ABOUT 45 MPH WHEN THE LEFT FRONT ABS ACTIVATED. IT WAS AN UNNERVING EXPERIENCE AND HAPPENED SEVERAL TIMES. I HAD THE SENSATION THAT THE VEHICLES WAS INSTANTLY PULLING TO THE LEFT WITH THE ABS DRAGGING THE LEFT FRONT BRAKE. I TOOK IT TO THE DEALER WHO CLEARED 5 CODES RELATED TO THE FRONT ABS SENSORS AND BRAKING SYSTEM. I'M A MEMBER OF AN ONLINE FORUM CALLED WWW.TRAILVOY.COM I SEARCHED THE FORUMS FOR "BRAKE SOFTWARE" AND FOUND MULTIPLE COMPLAINTS THAT REFLECT MY EXPERIENCE. THE DEALER, DANIELS CHEVYLAND TOLD ME THAT THEY HAVE HEARD THIS COMPLAINT, AS WELL. I AM VERY CONCERNED THAT IF THIS OCCURS ON GRAVEL, WET OR ICY ROADS THAT AN ACCIDENT COULD HAPPEN. THE DEALER TOLD ME TO KEEP DRIVING THE VEHICLE TO SEE IF IT HAPPENS AGAIN. THEY SUGGESTED THAT I BRING THE VEHICLE BACK TO HAVE THE BRAKE COMPUTER FIRMWARE UPGRADED IF THE PROBLEM OCCURS AGAIN. THEY WERE NICE ENOUGH TO SAY THAT THEY WILL DISCOUNT THE COST OF THE FIRMWARE. *TR

GAS GAUGE GOES FROM EMPTY TO FULL REPEATEDLY, REGARDLESS OF FUEL LEVEL. VERY COMMON ON ALL GM SUV'S MANUFACTURED IN 2006. LEADS TO VEHICLES RUNNING OUT OF GAS WHEN DRIVERS BELIEVE THEY HAVE A HALF OR QUARTER TANK OF GAS, ETC... *TR

AFTER FILLING GAS TANK, FUEL GAUGE DID NOT OPERATE PROPERLY, GOING FROM EMPTY TO FULL REPEATEDLY. CHECK ENGINE LIGHT CAME ON ALSO. *TR

I AM WRITING IN REGARD TO A FULL SIZED FAMILY VEHICLE THAT I LEASED IN 2006. I LEASED A 3 ROW 2006 ENVOY DENALI XL BY GM. I ALREADY HAD A 14 YEAR OLD SON AND DID NOT THINK I WAS ABLE TO HAVE MORE CHILDREN. HOWEVER, I HAPPILY DISCOVERED THAT MY HUSBAND AND I WERE EXPECTING IN MARCH OF 2007. THE ISSUE WITH MY VEHICLE IS THAT IT DOES NOT HAVE THE LATCH SYSTEM AVAILABLE IN THE CENTER OF THE SECOND ROW, WHICH IS WHERE I BELIEVE THE CARSEAT IS SAFEST. IRONICALLY, MY HUSBAND HAS A 2000 GMC EXTENDED CAB WHICH HAS THE LATCH SYSTEM IN ALL THREE SEATS OF THE 1/2 SECOND ROW. I HAVE CONTACTED THE DEALERSHIP, GM DIRECTLY, ETC. NO ONE HAS A SOLUTION TO THIS ISSUE. MY ARGUMENT IS THAT IF IN A CASH WITH THE CURRENT VEHICLE SPECS, THE SIDE AIRBAGS COULD DEPLOY, THUS HARMING MY DAUGHTER IN THE SIDE POSITION. HOWEVER, I BELIEVE THIS LACK OF THE LATCH SYSTEM IN THE CENTER IS AN OBVIOUS DEFECT THAT SHOULD BE CORRECTED. I WOULD APPRECIATE ANY SUPPORT YOU COULD PROVIDE. *TR

MY WIFE WAS INVOLVED IN AN ACCIDENT LAST NIGHT IN WHICH THE VEHICLE, A 2006 GMC ENVOY DENALI WAS TOTALED, BUT NEITHER AIR BAD DEPLOYED. *TR

WHILE DRIVING, CHECK ENGINE LIGHT CAME ON. FUEL TANK GAUGE STARTED TO CONTINUALLY SHIFT FROM WHATEVER STATE THE FUEL TANK WAS IN TO EMPTY THEN AFTER SOME TIME REVERT BACK TO NORMAL FUEL CAPACITY AT THE TIME. CONTACTED ONSTAR FOR A DIAGNOSTIC AND THEY STATED THERE IS A PROBLEM WITH THE FUEL SENDING UNIT. *JB
