do all AMG 2006+ roll backwards when going over a bump or driving uphill

 

if you have the car on the (S) setting or the (M)Manual it will rollback. If you wondering where that setting button is located at it is next to the gear shift. try using (C) comfort it helps reduce roll back substantially

 

As far as I know, my S63 has the equivalent of a "hill-holder" function that keeps the brakes on for ~1 second or until you press the accelerator while stopped on a hill; it does not roll backwards. I have no idea whether the C/M/S setting for the transmission changes that behavior.
