I find the 2010 suspension (with new tires) acceptable now Umm shouldn't you have more to say about the suspension of a brand new car? That's luke warm at best. I still have hope that (OK "solution" has too much baggage) for a "change" whether through an
aftermarket company or if Hyundai's '12 model parts becomes available. As I drove my car today I've come to think that it's not the general firmness that is irksome but how the vehicle handles the odd pot hole, speed bump or expansion joint...we'll see. Maybe I've gone on far to long about this subject and much like a bad relationship I should either remove myself or learn to live with it.
I am not sure I understand what you mean by "brand new car." As I have explained several times to you, in more than one thread, I have a 2009 purchased in January 2009 (assembled Oct 2008). The 2009 suspension was much worse than the 2010/2011 models, which had suspension changes implemented by Hyundai. I upgraded my 2009 suspension to the 2010/2011 specs about 10 months ago. That was the best I could do at the time, and it is now acceptable (it could be better, but I no longer have any desire to get rid of the car any time soon).
Yes, my comment about the suspension being only acceptable is a little "luke-warm." I think it is perfectly OK to say that Hyundai "should" have done better and had the 2012 suspension right from the start, but they didn't.
The main thrust of my comments were not that you complained about the suspension. Believe me, I have complained much more than you (I guess you didn't take me up on the challenge of reading all the old suspension related threads on this forum). My main thrust is to let you know that Hyundai is very unlikely to help you out with an official upgrade package, and definitely not selling you the parts at cost. The reason I believe this is that many people with the much-worse 2009 suspension complained to Hyundai, and they refused to help in any way, other than to suggest we purchase a 2010 model (with the improved suspension compared to 2009 model).
But there is some hope if you are willing to spend some money to upgrade your suspension to 2012 specs. But I don't know for sure how easy that will be, or how much it will cost (my suspension upgrade from 2009 to 2010 cost about $1700 parts and labor with an independent shop doing the labor). So I guess you will have to decide on a suspension upgrade at some cost to you (and some leg work to figure out how to do it), or live with it, or sell the car. I would advise against an after-market suspension upgrade (assuming it is possible to implement the Genesis 2012 upgrade on your car).
I have decided to keep my Genesis, but roads are pretty smooth were I live, and with the relatively moderate weather, very few potholes. I guess I could upgrade my suspension again to 2012 specs, but I doubt that I will do that, because I now find the ride on slightly rough roads to be acceptable , especially with my new Michelin Primary MXV4 tires. Ride on most well-maintained highways is close to perfect. Handling is definitely above average, as is virtually everything else in the car (compared to the competition in its price range). Steering could use some improvement, but they made changes for that in 2010 that I don't have on my 2009.
