My wife was driving our 2017 Acadia AWD Limited, today. She called me and said that twice the car started dinging at her, while driving. Once she got to her destination, she put it in park, left the vehicle running, and then shifted back to drive and drove home. She did not experience it on the way home. She said it was kind of similar to a door being partially ajar, but it didn't indicate that a door was ajar in the instrument panel. She said otherwise it seemed to drive ok. I had her send me a picture of the instrument panel, which is attached. I have never seen it look like this before. I did some searching and could not find anything. Any idea what this is?
