This is true. However, I've seen the same six people posting the same complaints about their cars' ride quality every chance they get. There is no problem with any Genesis's suspension, just people's opinions and the fact that the car doesn't meet there expectations. The cadence seems to be, someone asks an innocuous question, one of a few brings in mostly unsubstantiated arguments about how suspensions are flawed and Hyundai is out to get them, and eventually other owners can't take the Peter Wolf posts and chime in in response, and the whole thread falls apart.
The Genesis isn't the first car that I have heard has a bad ride, and it won't be the last, especially as long as people buy cars without really knowing what they are buying.
Not sure if I'm one of those 6 people you refer to, but I disagree that there is "no problem" with any Genesis's suspension and that it is "just people's opinions." You are also not being factual when you say "unsubstantiated arguments."
Let me address each one.
1. "no problem." That is only true if you didn't get a car that porpoises over certain road surfaces and you don't have to drive on said road surfaces.
2. "just people's opinions" A suspension that gets excited over surfaces which it should damp out is going into a resonance condition. This is not how a suspension should react...ever. Suspensions can be stiff. Suspensions can be soft. But they damping should always be sufficient to avoid a resonance condition. This isn't an opinion. It is an integral part of suspension design.
3. "unsubstantiated arguments." They are only unsubstantiated to you because you don't seem to believe people who have described the particular problem. My dealer was already aware of the issue from feedback from a customer when I talked to him about it. He corroborated the issue of porpoising which he said occurred with a customer who had a V8 Genesis.
While I would like my particular car to have better damping, I have been fortunate enough not to have driven on roads that caused the car porpoise. If I did, and Hyundai wasn't willing to fix the problem, I would be justifiably upset with them.
I also agree with people who say Hyundai should make the suspension upgrades easily available for customers who have earlier cars. Some people have suggested some parts were changed without changing the part numbers and I would be concerned that I wouldn't get the new part when ordering from the parts department stock.
When it comes to people's experiences, we should be able to agree that there can be differences. For example, I had a fantastic dealer experience and got a very fair price with only the minimum of upselling. Likewise, my service experience has been stellar. Others have had horrible experiences with dealers trying to charge MSRP, tacking on unwanted extras and the like. Others have described services where oil fill caps were not replaced and seats were damaged. I have no reason to believe they are lying and understand why these things would upset them.
My point is, if a discussion mentions something where someone wants to provide a bit of caution based on their experience it should be OK. The other people can counter by posting their positive experiences and we can have a nice civil discussion. It shouldn't turn into an attack on an individual, that makes the forum a hostile place and will drive people from it.
Forums should be open places where people aren't afraid to express their opinions and experiences. When they stop being that, and turn into a few cheerleaders patting each other on the back, they become irrelevant and therefore useless to all but those cheerleaders.
A good example of this is Michael Karesh's (TrueDelta) on a Jaguar forum. He is developing a website that tracks reliabilty data through customer surveys. He was kicked off the Jaguar forum website because his data and discussions of it reflected poorly on a new model. That forum did a nice job of hiding the problems with this particular car and anyone who used it, to make a purchase decision would have been very poorly served. The people who care to do more than just pat each other on the back for their purchase of that fantastic Jaguar, will quickly realize that forum is worthless to them. In Michael's case he was kicked off, but berating people for discussing their experiences is another way to drive them away. These people might end up helping us all...after all, the squeaky
wheel, does often get oiled, but we would never know about it because they wouldn't be here to let us know.
