Knock sound when suspension is hitting smaller short bumps (ie pot holes).

The dealer says they can’t reproduce the sound. One of their techs took me for a ride to find the problem, and drove down smooth roads 🤦🏽‍♂️. Tech says there's no witness marks, and will have to keep an eye on it. Problems still there at 2,900 miles. Still no fix.
