The dealership thinks I'm going crazy but others have heard it also. I have a 2017 Acadia AWD, with the lane keep and other bells and whistles. I'll be randomly driving and I'll hear 3 Star Wars like chimes. Like a high pitched pewpewpew. I haven't seen anything on the DIC and there have been passengers with me, all buckled up, and weighing in at more than 100lbs. For a short while, about 10 seconds, I was thinking it was a low battery warning on the fob but that should have an accompanied warning on the DIC, right? Please help! I am about to get admitted!
