2006 GMC Envoy Denali Xl

I WAS PULLING UP TO PARK IN A PARKING LOT.I HAD TOTAL BRAKE FAILURE. THE ELECTRONIC SAFETY FEATURES FAILED- AND THERE WAS NO STOPPING THE ENVOY. I SLID UP THE CURB AND INTO THE BUILDING. THE MECHANIC THAT REPAIRED THE ENVOY HAS A WRITTEN REPORT OF THE SAFETY SYSTEMS GETTING STUCK HALF OPENED AND THE BRAKE LINES BRAKING AND THERE WASN'T ANY FLUID IN SYSTEM. *TR

THIS MORNING, MY WIFE WAS PARKING AT ONE OF OUR KID'S SCHOOLS WHEN THE TRANSMISSION SYSTEM FAILED TO RESPOND. SHE ATTEMPTED TO PUT THE VEHICLE IN PARK, BUT IT WOULD NOT INITIALLY. ONCE THE SHIFTER WOULD MOVE FORWARD, THE VEHICLE DIED, AND CONTINUED TO ROLL FORWARD EVEN THOUGH THE SHIFTER WAS POSITIONED AS IF IN PARK. SHE HAD THE PRESENCE OF MIND TO LET IT ROLL UNTIL STRIKING THE PARKING SPOT CEMENT BUMPER. SHE REMOVED THE KEY FROM THE IGNITION, THEN ATTEMPTED TO RESTART THE VEHICLE WITH NO SUCCESS AND THE SHIFTER BUTTON WOULD NOT DEPRESS. SHE PANICKED BECAUSE OF LOOSING CONTROL OF THE VEHICLE WITH SO MANY SMALL KIDS AROUND AND CALLED ME. I LEFT WORK, AND UPON ARRIVAL ATTEMPTED TO TROUBLESHOOT WHAT CAUSED THE INCIDENT. I STARTED AT THE SHIFTER, SO I LOOSENED ALL THE COVERS AROUND IT, IN CASE THERE WAS SOMETHING BINDING THE SHIFTER. I ACTUALLY DID FIND SEVERAL SMALL ITEMS THAT HAD FALLEN IN THE COMPARTMENT THROUGH THE FRONT EDGE OF THE CENTER CONSOLE COVER ASSEMBLY. REMOVING THESE ITEMS STILL DID NOT ALLOW RESTARTING OF THE VEHICLE. I THEN LOOKED UNDERNEATH THE VEHICLE, AND DISCOVERED THAT THE LINKAGE FROM THE SHIFTER TO THE TRANSMISSION HAD SEPARATED. I MANIPULATED THE INPUT LEVER AT THE TRANSMISSION WITH MY HAND AND NOTICED THAT IT HAD MOVEMENT IN BOTH DIRECTIONS, WHICH MEANT THE TRANSMISSION WAS ACTUALLY NOT IN PARK. AFTER POSITIONING THE INPUT LEVER AT THE TRANSMISSION TO PARK, THE VEHICLE DID START. I SHUT THE VEHICLE OFF AND RECONNECTED THE SEPARATED LINKAGE. I WAS SHOCKED TO SEE THAT THE PIECE THAT MAINTAINS SUCH AN IMPORTANT LINKAGE CONNECTED APPEARS TO BE MADE FROM A PLASTIC. TO ME THIS IS A MAJOR ISSUE THAT CAN CAUSE SOMEONE TO POTENTIALLY HAVE A VEHICLE STUCK IN A MOVEMENT CAUSING GEAR, AND DUE TO A LINKAGE SEPARATION HAVE NO WAY TO PROPERLY TURN THE VEHICLE OFF (UNTIL IT RUNS OUT OF GAS), TO MADE FROM PLASTIC. PLEASE LOOK INTO THIS. *TR

RAN OUT OF GAS WITH THE FUEL GAUGE READING HALF FULL (VEHICLE HAD APPROX 50K MILEAGE). AFTER PUTTING A COUPLE OF GALLONS IN THE TANK WENT TO THE GAS STATION AND FILLED THE TANK. WHEN THE VEHICLE WAS STARTED THE GAUGE BOUNCED TO FULL AND THEN TO EMPTY. IT BEGAN BOUNCING UP AND DOWN CONTINUOUSLY, SOMETIMES SETTLING AT HALF FULL OR AT EMPTY. IT CONTINUES TO DO THIS TODAY (9/16/13) BUT MOSTLY STAYS ON EMPTY WITH THE FUEL GAUGE LIGHT ON ALL THE TIME REGARDLESS OF HOW MUCH GAS IS IN THE TANK. WE NOW USE THE TRIP ODOMETER TO GAUGE THE DISTANCE WE TRAVEL SO WE KNOW WHEN TO REFUEL. WE WERE TOLD BY OUR DEALER THAT IT WAS THE FUEL SENSOR AND WOULD COST AROUND $600-$700 TO REPAIR. *TR

TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. WHILE DRIVING APPROXIMATELY 60 MPH, THE ELECTRONIC STABILITY CONTROL AND TRACTION CONTROL WARNING INDICATORS BEGAN TO ILLUMINATE. IMMEDIATELY THERE WAS A SUBSTANTIAL REDUCTION IN THE SPEED RATE. THE FAILURE OCCURRED REPEATEDLY WHENEVER THE VEHICLE WAS IN OPERATION. ON TWO SEPARATE OCCASIONS THE ENGINE STALLED WITHOUT PRIOR WARNING AND RESTARTED AFTER WAITING A FEW MOMENTS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER SEVEN DIFFERENT TIMES. THE ECM WAS REPROGRAMMED AND THERE WERE NO ADDITIONAL REPAIRS PERFORMED ON THE VEHICLE. THE MANUFACTURER WAS NOTIFIED OF THE CONSTANT MALFUNCTION. THE APPROXIMATE FAILURE MILEAGE WAS 67,000.

I OWN A 2006 ENVOY DENALI AND LAST MAY 2010 I WAS DRIVING DOWN THE A BUSY HIGHWAY AROUND 55 MILES AN HOUR AND THE TRUCK JUST LOST ALL POWER AND COMPLETELY SHUTDOWN. IT TOOK ALEAST THREE TRIES BEFORE I COULD GET IT STARTED AGAIN. I WAS SO SCARED THAT A TRACKER TRAILOR WOULD HIT ME FROM BEHIND. IT DIDN'T DO AGAIN FOR A WEEK , AND THEN IT HAPPENED AGAIN. I BROUGHT THE TRUCK TO THE SHOP AND THE THROTTLE BODY WAS REPLACED AT ABOUT 65,000 MILES. NOW ITS A YEAR LATER AND I AGAIN WAS DRIVING ON THE HIGHWAY AND THE TRUCK ENGINE LIGHT CAME ON AND ALL POWER WAS LOST. I PUT MY HAZARDS ON BUT COULD ONLY GET THE TRUCK TO ABOUT 15 MILES AN HOUR SO THAT I COULD GET OUT OF HARMS WAY. I CALLED GMC TO MAKE AN COMPLAINT AS IT IS VERY RARE TO HAVE TO REPLACE A THROTTLE BODY EVERY YEAR. I TAKE CARE OF MY TRUCK AND SEE NO REASON WHY IT HAPPENING OTHER THAN GMC DEFECT. GMC DID NOT HELP ME AND JUST SAID THERE WERE NO RECALLS AND THAT IT WAS NORMAL WEAR AND TEAR. I NO THIS TO BE UNTRUE AND I AM VERY DISAPPOINTED WITH GMC AND WILL NEVER BUY THE PRODUCT AGAIN. I HAVE HAD NOTHING BUT ISSUES WITH THIS TRUCK, AND AFTER LOOKING INTO IT THERE ARE SEVERAL OTHER ENVOY OWNERS THAT ARE HAVING THE SAME PROBLEMS AS I AM. I DON'T DRIVE ON THE HIGHWAY IF I CAN HELP IT AT ALL, GETTING STUCK IN THE MIDDLE LANE WITH A TRUCK THAT WON'T MOVE IS WAY TO SCARY. GMC SHOULD HAVE TO MAKE IT RIGHT AND RECALL THE TRUCK AND FIGURE OUT WHY THE THROTTLE BODY FAILS. *TR
