Support for suspension issues

Try putting 150 lbs of weight in the trunk , you will notice a significant improvement in ride quality , much less bouncing. The rear springs on the Genesis are very stiff.
 
So you found a significant imrpvement? I had 50 pounds in back for awhile and noticed no change. If I use the car again I could try more weight. My trade in offer this weekend from an Infiniti dealer was not good (only $26,000) so I might be driving it after all. Not done trying to trade yet though.

I commented previously that it is sort of like a 1970's era full-size rear drive station wagon with no passengers. Also like pickup trucks of the same era that are empty.
 
Hmm... I live in south Florida and have driven in what I call "inch a minute" down pours with and without a passanger on local roads and I95 and not experiebced any problems. On one trip to the Keys it was raining so hard that traffic slowed to 20 mph on the Florida Turnpike. I weigh about 175 pounds. This problem seems to me is something that does not affect every car and sounds like some defect in putting individual cars together.

I would be trying to get the dealer to take the car back under the Florida Lemon Law if this happened to my car. In Florida they give you a little pamphlet detailing the Florida Lemon Law any time you buy a car

I have a V6.
 
Hello Richard:
Like you, I am located in S . Fla.
I believe that the lemon Law only applies after the third, ineffective dealer or manufacturer's attempt at resolution of a problem (in general terms) but since the manufacturer's rep. does not admit that there is a problem that requires resolution it would appear that the law does not apply.

I considered this option as well, prior to selling my 4.6 back to a local Deerfield dealer, but decided against it for the above reason.
BTW, depending upon where in S. Florida you are located, you may be familiar with the above dealer. I might mention that the ride issues in question were evident, to a somewhat lesser degree than other locations, on the stretch of Federal Hwy. that runs parallel to the dealership and were indeed recognized by the sale manager who did ride in the vehicle following the initial complaint.

Yes, the lemon law only applies after the third attempt to fix the problem. Sounds like a catch 22 if they refuse to recognize a problem.

I am not familier with the dealer in Deerfield. I visited three dealers, Coconut Creek where I bought my car and Rick Case in Ft. Lauderdale and Lehman in Miami. I will not do business with Lehman or Rick Case under any circumstances. They both tried to F... me. I like to be kissed when I'm getting f....d.

It seems that years ago one only encountered sleazy dealers when buying a used car. It now seems to be endemic with both new cars dealers as well as used car dealers.

Maybe I'll run up to Deerfield one of these days and see how my car reacts on the stretch of road you are talking about.

I've just Googled Deerfield Hyundai and I come up with King Hyundai. I think they actually own Coconut Creek Hyundai. If I remember right I think I made the check out to King Hyundai of Coconut Creek.
 
In Illinois you have to have four attempts to repair a problem before lemon law applies. That of course requires they first verify a problem and then attempt to fix it.

Here's something I discovered yesterday after more testing. Drove the same roads with a passenger (dry weather). The ride was a lot better - minor "bucking" was evident but much less extreme. Ride better overall. I also had my friend ride in the back over the really bad strecth on 355. The ride up front was still calmer/better. Not what I'd call great any means, but tolerable. In back over this stretch, however, my friend described the ride as really bouncy almost to the point of making him ill - he said there is no way he could take it for any length of time. Agian, this was over the worst stretch that causes bucking when I drive alone.

Thus, weight seems to be a big factor. So now if I keep the car it would appear I need to ride with 200 pounds of kitty litter in my trunk or in the passenger seat? LOL.
 
Glad I found this forum. We have been pretty much an Infiniti and Lexus family over the past 9 years. We currently have an '08 M35 and an '08 G37. The lease ends on my M this year, and I am already looking around. I have read great reviews on the Genesis, so I decided to check it out.

I went to 2 dealerships yesterday for test drives. On the first test drive, I found the car "bouncy". I thought maybe the tires were overinflated, so I asked the salesman if there was a tire pressure monitor that showed each tire's PSI (Infiniti has this). He said no, so I just dropped it. On the second test drive, which was a smoother road, I didn't notice this at all. I did notice the car cornered pretty flat, which was nice.

IMO, the Genesis is every bit as good, if not better, than what Lexus and Infiniti is offering. However, I did find the bouncy ride the first time around a bit disconcerting. I know what a "firm" ride is because my M35 has 19" rims and sport suspension. We also traded an FX35 for our G37, which has 19" rims, so I am familiar with firm (bordering on rough) rides! This was different.

I will be really interested to see how this plays out. I'm not into brands/badges, so I find the Genesis perfect in just about every way. I actually think Hyundai is positioned to become a really serious competitor in the years ahead. It's just that I am a bit concerned about the suspension issues I keep reading about.

BTW, there were also complaints about the rough ride of the SC430 when it was first introduced (largely attributed to the run-flat tires), and Lexus did change the shocks the 2nd year out. They retro-fitted to the first model year, so perhaps Hyundai may choose to do the same.
 
I put 160 lbs of sheet lead under the spare tire in the spare tire well. The spare tire still fits under the the trunk mat ( without the foam spare tire tool carrier ). The bouncy ride is now gone and the car rides the way it should. Hyundai needs to retune the rear springs/shocks to resolve the bouncy ride. I'm still getting 29-30 mpg on the highway at 75 mph and the car handles very well. Loading the trunk with weight is your best interim measure untill this Hyundai resolves this issue. The extra weight in the trunk dampens the stiffness of the rear springs.

The Genesis has a warning system that will tell you which tire is low, but doesn't tell you the exact PSI.
 
Holladay, thank you for your useful post on the weight you added. Can you post some pictures of what you have done so that others can copy?

Your useful suggestion is what makes forums like this and the internet valuable.

Wonder if a trailer hitch would do the same thing? I have a bike carrier and miss this option on my old VW Wagon.

Curt Receiver Hitches Hyundai Genesis 2009 / 09 Black Class II Hitch 12086

I'm going to try 40 pound bags of softener salt in the meantime. Where does one get sheet lead??
 
The 160 pounds in my trunk did not improve the highway ride to work. Still bucking and so much vibration coming through my legs are actually numb when I get to work. It does seem to make a modest improvement on normal rough roads around town, however.
 
Doug, Sorry to hear the added weight in the trunk didn't help. I am really beginning to think that your car might just be a one-of-a-kind dud, especially since things that help others have little to no effect for you. Added passengers help, but not added weight....I just don't get it. With the Hyundai rep in the car, it behaved fine, even over the worst stretch of road. I do not even know what could cause suspension problems to be so intermittent. I feel your pain. Your car does seem to be a unique example.

EXACTLY!!! He clearly has a dud/lemon/whatever you want to call it and his car is not representative of what the majority of us are experiencing. His car behaving fine with Hyndai reps and then back to its old tricks when they're not in the car isn't just bizarre, it's just not very believable quite frankly. I've been following his posts in Edmunds and he is getting the same questionable responses from the folks over there.

I believe he would be happier to just get rid of the car and buy something else.
 
I actually started by putting 200 lbs in the trunk , then 160 lbs , then 120 lbs. I could tell the difference in ride at each step . 200 lbs really calmed down the car but for me 160 lbs gave the best results. I have the V6 with 17 inch wheels. I used some 1/2 inch lead lined sheetrock from my construction connections.I have never had any vibration in my car, only a bouncy rear suspension.
 
It's completely nuts - I wonder if it makes a difference where the weight is placed - passenger seat vs. trunk. Clearly the rain made a difference which is crazy. I've talked to two others who also didn't see much improvement with added weight in trunk. Anyway - the regional rep asked me if they could try something before I try to trade it in and I agreed. Tommorow they will attach computer/sensors to it and I'm to drive normally for the day. This will record data and may reveal something. As he indicated it could also be the transmission causing some jerkiness. Failing that I'm at a loss - literally! Thanks again everyone.
 
I'm impressed that they are concerned enough to install the sensors. On the other hand, I think they should offer to buy the car back if the data from the sensors shows anamolies. It is more than coincidence that people on this forum are discussing adding weight and where to put it. Hyundai's marketing people rightfully want the Genesis compared to BMW, Lexus, and Mercedes Benz models, and I bet their respective forums aren't discussing where to add weight to make the car livable. The Genesis is a great car, but Hyundai needs to step up the response and get in front of these suspension claims. In the scheme of things, it'd be much cheaper to buy back a few cars than to be labeled defective and be tarnished forever.
