Salam, I have the same issue with my Corolla 2011, rattles on speed bumps and bumpy roads. Should get it replaced under warranty ASAP.
Bro Second thing is if you're not satisfied with their response try emailing Honda Atlas and I'm sure you'll get called and invited to have your problem solved. I have tried this and it was fruitful.
