Does it happen after the car has been sitting in the rain or damp weather? Sometimes I get a clang noise after it's been raining and I attribute it to the rear brake pad getting lightly rusted to the rotor and it unsticks and makes that loud metal clang.

No doesn't have to rain for example just few days ago I was at the park few hours when I left the park the weather was good btw 2 miles down the road as I started driving once the traffic light turned green I take off in first then went to second gear and bang bang it happens twice in a row
it’s a pretty loud hit somewhere in the back anyone in the car would feel and hear it can freak you out!

Did you get to the bottom of this issue?
