2017~2024 CX-5 Clunk noise in front when backing out

:
2019 CX5 Reserve AWD
2019 GTR, 30,000 miles on odo. When backing out of my driveway and hit the little dip between driveway and street there's a
pronouced clunk sound from the drivers side front. My wife had the car into the dealer for a nail in the tire the other day and
asked them to check the suspension for the noise. They said everything looked good. This morning I heard the noise again.
That's the only time I hear it, over road bumps, speed bumps it's quiet.

Anybody experience anything similar? Anybody have any ideas what to check?
 
I suspect the brake pads are shifing very slightly in the calipers. My 2016 and 2021 GTR also does this. Ed
