Mark...have you had conversations with Hyundai? I've spoken with several members of the Genesis team on unrelated matters and they have proved extremely helpful. I don't see a problem with you seeking a resolution, free or otherwise (I myself got the trunk liner and am currently awaiting reimbursement), but it just strikes me, right or wrong, that the back and forth you're having with members here ought to be with the people at Hyundai who at least have the ability to do something about it. If you find out new information as you go along, I'm sure members would be very receptive to that. I know I would. Again, I apologize if I offended you or anyone else. This will be the last I post on this topic.
Because people who want to discuss the suspension issue on this forum are often attacked and harassed, there is sort of an underground forum consisting mostly of PM's and emails among people who do want to discuss it. I know of two people who pressed very hard with HMA, and the final resolution was that if a owner thinks the 2010 suspension is better, trade your 2009 car in for a 2010 model. HMA said that they will not provide any information to dealers on how to upgrade the suspension and they would discourage such activity. My suspicion is that HMA is afraid of some legal problems if they facilitate the upgrade in any way, but I don't now what they are thinking for certain.
At least one person posted in this forum that he had his brother (an experienced mechanic) order the 2010 parts (springs and shocks) and install them on his 2009 model, and reported a definite improvement (but still "pleasantly" firm).
I am not sure what I will do, but I am casually looking for a good mechanic to do the work, since apparently Hyundai dealers are being told not to do it. But I never claimed that the 2009 suspension is horrible, so I am not loosing any sleep over it.
Quite a few members on this forum seek to improve their car with different
rims, tips, pillars, exhaust systems, headers, ECU chips, HID lighting, LED interior lighting, sub-woofers, ad nausea, so I don't see what the big deal is about someone wanting to get the 2010 suspension upgrades on their car. Personally, I think most of these other
mods and upgrades are a bit ridiculous, but I don't harass other people about it because it is their car, their money, and they have a right to free speech.
