I purchased a used certified 2014 Acadia 4 months ago. Since the second week of having it the truck shuts off for no reason. Happens when driving at a slow rate. Examples are pulling out of driveway, after being stopped at a stop sign, driving through a parking lot, going up or down an incline. The truck stutters and either shuts off or catches itself. I have brought it to the dealership more than 3 times and it's never fixed. My VIN is not listed in the stalling or ignition switch recall. It started intermittently but now it's everyday although dealership says they can't duplicate what I'm describing. It has stopped at a stop light and I had to hurry up and hit the hazard lights so I had time to put it in park and restart the engine. However as long as I'm driving on the freeway it's fine. Just when I'm going less than 35 mph.
