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
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
