Twice I’ve heard a popping/thumping noise while driving my 2017 Outlander Sport . The car doesn’t lose power. The popping is so loud that it seems to cause the air pressure inside the car to change.its so bad I have to pop my ears. The sound is greatly reduced if I open at least one window. If you ever heard popping from an electric fence it something like that only faster and more muffled. Help!
