DRIVING AT ROUGHLY 50 MPH. WENT TO PASS CAR ON TWO LANE HIGHWAY. ACCELERATOR STUCK TO FLOOR (NOT STUCK ON FLOOR MAT OR OTHER OBJECT). VEHICLE ACCELERATED TO 95 MPH, SLOWED TO 70 WITH BRAKE DEPRESSED FULLY. SLOWED TO 50 WITH BRAKE AND EMERGENCY BRAKE DEPRESSED. ACCELERATED WHEN DOWNSHIFTED INTO MANUAL. FINALLY PUT IN NEUTRAL AND WAS ABLE TO STOP. HAD COMPLAINED OF ROUGH IDLE, STALLING AND REDUCED POWER FOR 3 YEARS (SINCE WE HAD CAR FOR ONLY A FEW MONTHS). SEE SOME DISCUSSION THAT A DIRTY THROTTLE BODY COULD LEAD TO ALL OF THESE PROBLEMS. 3 YEARS WITH 3 DIFFERENT GM SERVICE SHOPS AND NO SOLUTION. FORTUNATELY THE ROAD WAS NOT CROWDED AND WAS STRAIGHT. OBVIOUSLY, THIS COULD HAVE BEEN A FATAL PROBLEM FOR US. IT WAS MY WIFE, MYSELF, AND OUR THREE CHILDREN UNDER 4 YEARS OF AGE IN THE VEHICLE. *TR

SINCE MARCH OF THIS YEAR WE HAVE 3 OF THE 4 DOOR LOCKING ACTUATORS FAIL AND REPLACED ON OUR 2009 GMC YUKON DENALI WITH ONLY 39000 MILES ON IT. WE CONTACTED GM VIA E-MAIL WITH OUR CONCERNS. GM ARE NOT CONCERNED WITH IT BEING A SAFETY ISSUE. THE ONLY THING THEY WERE CONCERNED WITH WAS IF IT WAS REPORTED TO A GM DEALER, IF NOT IT WAS NOT A CONCERN OF THEIRS. WE HAD OUR LOCAL MECHANIC FIX THE ISSUE DUE TO THE DISTANCE TO OUR DEALERSHIP AND OUR VEHICLE BEING JUST OUT OF WARRANTY . MY WIFE AND CHILDREN HAVE HAD CRAWL ACROSS THE VEHICLE TO EXIT. MY CONCERNS AFTER LOOKING UP THIS MAJOR SAFETY ISSUE, ON THE INTERNET, IS THAT THERE ARE A LOT OF SIMILAR COMPLAINTS REGARDING THIS SAFETY ISSUE, BUT GM HAS CLASSIFIED THIS A PROBLEM AS A "NON-SAFETY ISSUE". WHEN MY WIFE AND CHILDREN CAN NOT EXIT THE VEHICLE THROUGH THE DOOR THEY ARE SITTING CLOSEST DUE TO A ACCIDENT , FIRE, OR SOME OTHER FORM OF AN EMERGENCY, IT IS A SAFETY CONCERN. *TR
