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. NOW THE GAS GAUGE FLOATS BETWEEN FULL AND EMPTY CONTIONUSLY. THIS WAS A VERY DANGEROUS AND SCARY SITUATION BOTH TIMES. MY FLASHERS WERE ON THE WHOLE TIME AND I HAD TO CHANGE THE BATTERY. NOW THE AIR WILL NOT COME OUT OF THE VENTS ONLY THE FLOOR AND DEFROST. BUT THE MOST IMPORTANT THING IS THE GAS GAUGE, I COULD HAVE BEEN INVOLVED IN AN ACCIDENT BOTH TIMES. *KB

2006 ENVOY DENALI. CONSUMER WRITES STATES GAS NEEDLE STOPPED FUNCTIONING *TGW THE CONSUMER STATED THE GAS NEEDLE BEGAN TO FLUCTUATE IN THE BEGINNING AND SINCE THAT TIME, THE NEEDLE HAS BEEN STUCK ON EMPTY, AND THE ENGINE LIGHT ILLUMINATED AS A RESULT. IN MARCH OF 2009, WHEN THE CONSUMER STARED THE VEHICLE, IT SOUNDED AS IF THERE WAS SOMETHING METAL TUMBLING AROUND UNDER THE HOOD. UPON INSPECTION OF THE VEHICLE, IT WAS DETERMINED THE ENGINE NEEDED TO BE REPLACED. ON JUNE 10, 2010, THE VEHICLE WOULD NOT START AND HAD TO BE TOWED TO THE DEALER. AN INSPECTION REVEALED A STARTER WAS NEEDED. ALSO, AN ALIGNMENT WAS DONE AND THE REAR BRAKE LIGHT WAS REPLACED. ON JUNE 12, 2010, THE VEHICLE WOULD NOT COME OUT OF PARK. AFTER 25 MINUTES AND OVER 50 ATTEMPTS, IT FINALLY CAME OUT OF PARK. THE CONSUMER DROVE TO THE DEALER, BUT THEY WERE UNABLE TO FIND A PROBLEM. SEPTEMBER 2010, THE CONSUMER NOTICED THE REAR OF THE TRUCK WAS SITTING VERY LOW. THE REAR END AIR SUSPENSION NEEDED TO BE REPLACED. THE AIR CONDITION RANDOMLY WORKED. THERE WERE TIMES WHERE THE AIR WOULD JUST START BLOWING AND NO BUTTONS WERE PUSHED. ALSO, THE DEFROSTER STOPPED WORKING. THE CONSUMER CONTINUED TO EXPERIENCE PROBLEMS WITH THE VEHICLE NOT COMING OUT OF PARK. *JB
