What 260 owners told NHTSA about the 2015 GMC Acadia Limited

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.

WHILE THANKFULLY DRIVING IN THE SLOW LANE ON THE INTERSTATE IN ST. LOUIS MY STABILITY LIGHT CAME ON THE TRUCK THEN SLOWED DOWN ON ITS OWN THEN WENT INTO FOUR-WHEEL-DRIVE THEN REVVED UP TO 6000 RPMS THEN EVERY SERVICE LIGHT CAME ON ON THE DASH WHEN PULLING TO THE SIDE OF THE ROAD THE CAR THEN WOULD NOT DRIVE FORWARD IT STAYED IN NEUTRAL REGARDLESS OF GEARSHIFTING IT THEN BEGAN TO CYCLE THROUGH ALL OF THE SERVICE REQUEST FOR THE VEHICLE. AFTER HAVING TO HAVE THE VEHICLE TOWED TO THE NEAREST DEALERSHIP WHICH WAS THREE HOURS AWAY FROM MY HOUSE THEY INFORMED ME THE FOLLOWING MORNING THE POWER STEERING CONTROL GEARBOX HAD WENT OUT AND FRIED ALL THE ELECTRICAL'S INSIDE THE VEHICLE. THE VEHICLE HAS LESS THAN 39,000 MILES AFTER CONTACTING GMC THEY TOLD ME THERE WAS NOTHING THEY COULD DO THAT THERE WAS NOTHING ON A RECALL LIST FOR MY VEHICLES VIN NUMBER. AFTER DOING SOME RESEARCH I SAW THAT THERE WAS A RECALL FOR A VERY SIMILAR SITUATION IN 2018 IN SEPTEMBER. I HAVE VIDEOS OF THE VEHICLE COMPUTER SYSTEM MALFUNCTIONING IF REQUESTED. I JUST WANTED TO DOCUMENT AND FILE A COMPLAINT SO THIS DIDN'T HAPPEN TO SOMEONE ELSE AND CAUSE A SERIOUS WRECK , SINCE GMC HAS FAILED TO RECOGNIZE THIS SERIOUS OF AN ISSUE.

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.
