    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum.

So I'm tring to find more info about the suspension components of the Genesis.

So far, this is the best I've seen at explaining the ZF SACHS ASD system on the Genesis:

Variable without electronics
Amplitude-selective damping called Sensitive Damping Control functions without electronics and is an evolutionary advancement of today's standard dampers. The amplitude-selective damping design developed by ZF Sachs can be found in North America's "Car of the Year" – the Hyundai Genesis. In this component, an additional valve is used on the piston rod which is suspended between springs and, depending on the tuning philosophy, has a certain amount of play. For minor stimulations, only the standard valve is actuated, for major stimulations, the damping forces of both valves are made available. With the additional valve characteristic (piston with spring-loaded valve disks and bypasses) and the definition of the available play, this solution means that to a large extent, the area in which the damper switches from soft to hard is adjustable independently.

To me, this basically states that the Genesis suspension is not electronically controlled, but the shock is possible manually adjustable. This might be a path to changing the ride quality of a Genesis, but its nothing definite for now. Worst case scenario, if you think your suspension is too hard or soft, all you have to do is replace the shock.

So if this is true then it may explain why some of us have an issue with the ride quality and others dont. Maybe its just an adjustment to be made to either soften or harden the ride. That would be really great news if this is true !!:)

Or, it may be the reason some people experience too much lope on low speed bumps - the shock isn't reacting as it should for that speed. Afaik, this system is only on the Genesis and Equus, so its a new system that may need a tweak. Imo someone needs to take a wheel off and take a look at the shock, and let us know if it is really adjustable or not.
