F30 2016: I have a very loud clunk as your car drops down the far side of a speed hump twice in 2 years. This happens when you brake suddenly (You are not aware of the hump then brake and drive over a decent speed like 20-30km/hr) and drive over the speed hump. It does not happen at normal case when with sudden brake and over the speed hump. I experience twice in 2 years now. Do you guys experience this? Is it a big problem.
