Hi! I am a new owner of a 2016 GLE 4 MATIC. I picked it up last week and I love it! I am trying to learn all of its great features. I notice that, on occasion, it feels like someone is hitting the steering column with a hammer or some object. The "pounding" is three or four "hits" in a row, then it disappears. Could this be a vibration from the Active Lane Assist feature? Thank you for any information.
