2015 GMC Acadia

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 and thankfully was able to get it to work with the check engine light showing. I called the car dealership that I go to for my oil to let them know I’m coming and that it stalled again with the check engine light showing. I made it to the shop and they ran diagnostics on it to show that it was a time change in the engine that was messing up. They then proceeded to let me know that I would have to go to a GMC shop because they can’t do the work at their shop. He then proceeded to tell me not to drive in this because the car will stall in motion and will not go faster than 45 without dying or shutting off. Which to me is a major safety concern since I have to drive it to the shops and let along home with my children in the car. So the whole way I couldn’t go over 45 without my car starting to stall and shake. Thankfully it didn’t shut down with my kids in the car on a main road.

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 ISSUE AND TODAY RETURNED MY VEHICLE TO ME WITH AN APOLOGY FOR NOT BEING ABLE TO REMEDY THE PROBLEM. THEY CLAIM THAT THE VEHICLE MUST EXHIBIT THIS BEHAVIOR IN THEIR PRESENCE TO WARRANT A FIX. THE VEHICLE IS UNDER AN EXTENDED WARRANTY THAT CLEARLY COVERS THESE PROBLEMS. I WOULD BE HAPPY TO EMAIL THE VIDEOS, BUT THEY ARE NOT IN THE SUPPORTED FORMAT AND LIKELY LARGER THAN 5MB.

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.

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.
