Thumping in rear of car

I would use your warranty and have Honda check it out.

I would take it back to the dealer but before u drive it, inspect to make sure u don't have a loose wheel

Ok will do thanks.

I’ve been chasing this for months!! The cha chunk sound you hear every time u go over a bump. It’s not just the 17’s that do it they all do from 16 and newer. I sold Honda’s for 5 years and bought one when I retired now I drive cars for the dealer and pick up cars at other dealers nothing in the Honda lineup makes this noise. I can’t believe in the reviews someone hasn’t picked up on this??
