I have a 2012 GMC Acadia that just hit 113k miles. Recently, I have heard a rattle noise almost like if you were to take screws and shake them in an empty plastic bottle. It doesn’t happen every time I accelerate but it usually occurs if the car hasn’t been driven in a day or two. No check engine lights or any other signs of what it could be. It happens from a complete stop and eventually goes away after a few seconds. Any ideas?
