2015 GMC ACADIA Vehicle Speed Control Problems

Today I encountered a problem with my vehicle that not only put myself at risk but my children. This problem came out of no where since I have not had any problems with my vehicle before today. When going to leave I turned my car on to have it stall and die. I had someone come out and look at it and got it to work by pushing down on the gas pedals. Said nothing looked wrong since there were no check engine light or any codes coming up on the dash. So I proceeded to leave and go get gas. When going to start my car again it stalled yet again and showed a check engine light. The car then started to smell like smoke and gas to where I immediately turned to car off and had my kids get out. I then tried to start my vehicle again...

THE SUV STARTS TO PULL WHEN GEAR SWITCHES TO THE NEXT GEAR MAKING MY SUV NOT CHANGE GEAR TOOK IT TO A MECHANICAL THEY SAY IT'S THE ADJUST CLUTCHES IT SHOULD BE RECALL BUT IT'S NOT

MY CAR WHINED AND GROANED WHEN YOU TURN THE WHEEL SO I TOOK IT IN AND HAD THE POWER STEERING PUMP REPLACED AND NOW MY WHEEL.WONT TURN AT ALL .UPON READING MANY COMPLAINTS WITH THIS VEHICLE FOUND IT MAY BE THE RACK AND PINION I AM.GOING TO HAVE TO TOW TO A DIFFERENT MECHANIC TO SEE IF THE NEW PROBLEM IS COVERED UNDER WARRANTY.

IMMEDIATELY AFTER FILLING THE TANK WITH GAS, I STARTED THE ENGINE AND IT ACCELERATED TO FULL CAPACITY. THE ENGINE HAD MADE CLICKING SOUNDS, AND OTHER SOUNDS WHEN IT STARTED.

ON 15 PLUS OCCASIONS, WHILE THE VEHICLE IS STATIONARY, IN THE PARKING GEAR AND RUNNING, THE FRONT END WILL START TO VIBRATE MILDLY, INCREASE IN INTENSITY AND THEN THE TRACTION LOSS LIGHT ILLUMINATES, A BLINKING ENGINE LIGHT ILLUMINATES, "SERVICE STABILITRAK" AND "SERVICE TRACTION CONTROL" MESSAGES APPEAR. THEN TRACTION CONTOL OFF APPEARS, FOLLOWED BY AN AUDIBLE LOUD CLICK AND VIBRATION CEASES, MESSAGES DISAPPEAR AND LIGHTS TURN OFF. ONCE WHILE VEHICLE IN DRIVE AND BEING OPERATED ON A ROADWAY, I PULLED RIGHT AT AN INTERSECTION TO HAVE THIS SAME SEQUENCE HAPPEN DURING DRIVING, RESULTING IN AN ALMOST COMPLETE LOSS OF POWER AND ACCELERATION AND A NEAR ACCIDENT. THE SEQUENCE WAS IDENTICAL AND ONCE THE ERRORS CLEARED THE VEHICLE ACCELERATED RAPIDLY AND FORCEFULLY. I HAVE DOCUMENTED MULTIPLE OCCASIONS ON VIDEO WHILE STATIONARY OVER A MULTI MONTH PERIOD AND HAVE FURNISHED THOSE DOCUMENTS TO MY LOCAL GMC DEALERSHIP WHICH HAS FAILED TO REPAIR THIS...

TL* THE CONTACT OWNS A 2015 GMC ACADIA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE EXPERIENCED UNINTENDED ACCELERATION AND THE CONTACT HAD TO EXERT EXCESSIVE PRESSURE TO THE BRAKE PEDAL. THE CONTACT THEN HEARD AN ABNORMAL NOISE COMING FROM THE FRONT OF THE VEHICLE. THE CONTACT STATED THAT THE VEHICLE INDEPENDENTLY DISENGAGED AND SLOWED DOWN. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED AND MADE ARRANGEMENTS TO HAVE THE VEHICLE TOWED TO A DEALER. THE FAILURE MILEAGE WAS 35,021.

SERVICE STABILITRAK--TRACTION CONTROL OFF! MESSAGE, THEN CAR RAN ROUGH AND LUNGED ON ACCELERATION. THIS HAPPENED AT 5,000 MILES, REPAIRED AT DEALER. AGAIN ABOUT 12,000 ON A TRIP AND RESET ITSELF. NOW, AT 20,000 MILES SAMES MESSAGE AND IS AT THE DEALER BEING REPAIRED. THIS IS A SAFETY HAZARD. PLEASE INVESTIGATE THIS.
