2006 GMC Envoy Denali Xl

THE INITIAL TIME (3/14) IT OCCURRED, I WAS OUT OF TOWN WITH MY FAMILY, EMBARRASSED TO SAY THE LEAST. HOWEVER, MAINLY UNCOMFORTABLE, TIRED, AND FRUSTRATED BECAUSE MY 87 YEARS OLD DAD WAS STRANDED FOR HOURS AS WELL AS MY 66 YEARS OLD SISTER WHO IS RECOVERING FROM CANCER. THIS PROBLEM WAS A SERIOUS PROBLEM BECAUSE OF OUR LOCATION. WE HAD GONE TO GET DINNER AND ICE CREAM AFTER GETTING ICE CREAM WE BACK IN THE VEHICLE FOR IT WOULD NOT START. I CALLED 911 NO POLICE EVER SHOWED NOR WOULD EVEN STOP TO ASSIST. AFTER 2 1/2 HOURS, WE CONTACTED A CHURCH MEMBER TO FIND OUT ABOUT A MECHANIC IN THE AREA THAT COULD POSSIBLY COME CHECK IT OUT. ANOTHER CHURCH MEMBER CAME TO CHECK IT FIRST, BY NOW 3 HOURS HAVE LAPSED AND THE VEHICLE STARTS. AFTER THIS IT HAS HAPPENED ON THREE (3) SEPARATE OCCASIONS WITH ME (3/19, 3/20, & 3/21) BUT MY MECHANIC SAID IT HAPPENED WITH HIM 3 OR 4 TIMES WHILE HE WAS DRIVING IT TO CHECK IT OUT AND WHILE IT WAS SITTING JUST RUNNING NOT BEING DRIVEN. I WAS ON THE INTERSTATE ONCE, ONCE DRIVING, AND ONCE PARKED AND IT WOULD NOT START. THE TIMES I WAS BY MYSELF ONCE WAS ON THE INTERSTATE, ANOTHER WAS GOING THROUGH AN INTERSECTION, AND ONCE WAS IN A HIGH CRIME AREA WHERE I FELT VERY UNSAFE FOR MY VEHICLE AND MYSELF. MY MECHANIC REPLACED THE CRANKSHAFT AND CAMSHAFT SENSORS AND THE PROBLEM PERSISTS. I HAD A DIAGNOSTIC TEST PERFORMED BUT WAS TOLD THE ITEMS LISTED ON THE TEST 'MAY' BE THE PROBLEM. I HAVE ALSO HAD A PROBLEM WITH IT ACCELERATING WHILE DRIVING AS IF THE GAS IS NOT DISTRIBUTING PROPERLY. IT WAS AS IF IT WAS CHOKING UP AS IF THERE WAS A CLOG. A DANGEROUS PLACE TO BE IN TRAFFIC OR GOING ACROSS A RAILROAD TRACK, WHICH IT HAS OCCURRED SEVERAL TIMES WITH ME. I ACTUALLY WAS ALMOST REAR ENDED ON THE INTERSTATE.

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
