Suspension - Test Drove 2009 and 2010 Genesis back to back

I agree about the Dunlops that's one of the reasons why I changed tires.

I found it interesting that on Hyundaioemparts.com they list under rear shocks etc. 2 different catagories "with sport suspension" and "without sport suspension" wonder what that is all about?

Genesis Coupe :)
 
Glad to know, could not determine that from the site, thanks.
 
Another observation, it seems the V6 owners are complaining more than the V8 owners.

Actually, when I investigated it by searching I found more V8 complaints...especially regarding porpoising. Porpoising is where the shocks aren't damping the vehicle enough over wavy roads and the car heaves forwards and backwards like a porpoise. I suspected the weight of the V8 might put it closer to the resonance condition of the suspension. Better damping would really help. It is a bit counterintuitive, but the ride might actually improve with stiffer shocks. They would reduce the travel going over bumps. I suspect this underdamped "pitching" is what many people are feeling...especially in the back seat.
 
IMO the lack of rebound control (pulling up) by rear shocks is the primary cause of the proposing. The rear shocks are overly damped in compression leading to the sharp impact from small objects like very minor pot holes and ridges in the pavement.

GripperDon, I am interested in your modification list in your sig.file. Have you posted any pictures of your car? I, for one, would like to see it.

The springs are overpowering the shocks. Hyundai changed both in the 2010 model, and many suspect they softened the springs and stiffened the shocks so the shocks can do their job. I don't think the changes were major, but just enough to get things is balance.

Those looking for soft cushy ride should look elsewhere, since the 2010 changes are not going to change the overall character of the ride firmness.

Re: Suspenstion - Test Drove 2009 and 2010 Genesis back to back

Why do you always come to the suspension threads and post?
Why do you do this despite the fact that you DON'T have a Genesis anymore?
Why do you ALWAYS look for these threads and can't wait to post negatively?
Because you have an agenda...that's why!

Get a life, grow up and move on...some of us "REALLY" enjoy the car! Some of us also think it's da'bomb!

You're "agenda" is really childish.
Sheesh

Been away for a bit...just to go on record, yes the ride is somewhat stiff but I truly feel this is the best car I have ever owned. Everyone who drives with me ends up with the same amazed expression.

Now if only I could justify trading in so soon for an Equus....
 
I just bought a 2010 4.6 and I love /hate this car.

From the floorboards up it is fantastic but the ride is not very good. I bought my wife a 2010 Maxima and it rides much better.

Consumer Reports calls the ride "Unsettled" and I think that is being generous.
Now for my question. Can I substitute after market shocks for a smoother ride ?
Would lowering the tire pressure to, say, 30 or less, from 33 PSI make any difference?

Is my experience unusual and are there any steps I can take to make it ride smoother ?

Thanks for any help, guys.

I lowered my tire pressure to 31 psi on my 2009 Genesis. Be careful about going much lower, and be careful how/when you measure the pressure (measure when tires are "cold") because the TPMS is fairly sensitive.

Cars are shipped from Korea with very high psi (dealer prep is supposed to lower it to 33), so make sure it is set to 33 before you decide to lower it.

I doubt that changing the shocks alone will help, but you can try it. The shocks and the springs probably need to changed in concert. But I don't think you are going to get a soft/cushy ride no matter what you do (short of installing the Korean version of the Genesis air shock/spring assembly), because the was not the design intention of Hyundai for the North American Genesis.
 
I don't get it...I bought the 2010 4.6 tech in October and I absolutely love this car (even the ride) You all had the opportunity to test drive it and research it prior to buying. Its a firm european ride....GET OVER IT!! After owning at least 47 automobiles prior, I defy you to find a better buy out there!

While I agree that buyers should accept that the Genesis has a firm ride by design, and I think the 2010 suspension improvements should satisfy those who complained about 2009 porpoising (etc), I am puzzled by the statement:

"I defy you to find a better buy out there!"​

This seems like a non-sequitur to me. Just because the Genesis is probably the best buy in a car out there (I definitely agree with you on that) does not mean that the car is perfect. A lot of other posters have complained about other Genesis problems, but fortunately none of them have affected me (or I find their complaints trivial). But I would not dismiss someone's specific complaint just because overall the Genesis is an excellent car and an excellent value.

But again, if someone finds the 2010 suspension too firm, they should understand that it was designed with a "European" firm ride. The Korean version of the Genesis has an air shock system that was deemed by HMA to be too soft for American tastes (or at least too soft for the American auto press who reviews cars).
 
Could we please ask that before berating others that if you post about this topic to at least be informed about the nature of the complaint and the circumstances surrounding it? People are not complaining because it has a "European", "sporty" or "firm" ride. They are complaining because (some) have experienced downright unusual, odd behavior and excessive (for any vehicle) bounciness/jitterinesss. Many of us wanted a firm ride, did extensive research and test driving only to still end up with the problem.

Thank you

As I have said a lot on how to "Fix" the ride I'll just say my ride to me is "HARSH" not European or firm. I have owned so many German cars it is hard to list them all and American and Asian cars as well. I love the car as well, that does not mean it is flawless or that it is someway wrong for me to comment on an area I don't personally like that if you like that area fine,I am talking about the car not you. Finally I don't have to get over it, Tell that to Tiger's wife not me. :D
 
Re: Suspension

Thank you, Matt, for putting your moderator hat on. I too love this site.
I've been viewing it for 2 months now, and just picked up my new 4.6 tech 5 days ago! I've been in a 2007 E-550 Benz for 33 months, and I find my 2010 Genny to be quite 'bouncy' as others have described their 2009 to be. My dealer located my color/package from another dealer 90 miles away, and by the time I got it there was 250 miles on it. I have a wild imagination, and am starting to wonder if somewhere along the line my shocks got swapped out with 2009's. Is there a way to check? The freeways are pretty smoothe here is So. Cal and I am familiar with my usual route, and I am getting bounced around pretty good on roads that I know are pretty level...*especially the toll roads here in South Orange County). I'm 6'3 / 230 lbs and often times get bounced to where my sholders hit the bottom of the headrest and it raises it up a notch. Very descouraging. I haven't driven it with 4 passangers yet ( maybe it rides better with more weight) I'll let ya' know. I actually doubt that my shocks have been tampered with, but does anyone know if there are stiffer ones available to reduce that boing, boing, boing as I go down the road? Otherwise, this car is an aboulute delight and a blast to drive, quick, nimble, light, roomy and just so damn much fun! OOPS... a swear word. Sorry. Any suggestions on calming down this suspension would be appreciated.

Mike some Possibilities:

1. Change wheel diameter down 1"
2. Increase series of tire. (Side wall height)
3. Add weight to rear trunk floor.
4. Lower tire pressure.
5. Change tires to smoother construction :Serenity or Comfort tread.
6. Find Shocks that fit and are better suited to suspension.
7. Find softer springs for rear that fit.
8. Locate softer struts for front, that fit.
9. Reduce diameter of anti-sway bar.
10.Trade car.
:welcome:

Mike, in all fairness, it is really unlikely that someone would have removed all of the suspension pieces from your 2010 and replaced them with components from a 2009. As you have probably noticed, the topic of suspension harshness is a big topic here and with folks sitting on either side of the isle. While Hyundai claims to have made significant changes to the Genesis suspension for 2010, in my own personal experience, I personally did not notice any differences between the ride of a brand new 2009 and the ride of a brand new 2010 when driven back to back. Maybe I am just not as sensitive to the suspension "bouncyness" as others here. The Genesis is firm to be sure, but, to the seat of my pants, it is no "bouncier" than a BMW 550i (in fact, there have been similar reviews about the 550i being too stiff when compared to the cossetting ride of other Lux cars.) I think that everyone here has a right to voice their concerns, issues, Mother's Maiden names, Visa Card numbers, or whatever else they would care to share. The bottom line is that perhaps there is a fix to make the care respond to your liking, perhaps not. I certainly hope that the "bouncyness" you are experiencing is just the heightened sensitivity that many feel with new cars, and, that once that settles down you will be happy with your purchase. Maybe you need to take a couple exit ramps at double the posted speed to see the benefit of that tight suspension.
 
Gripper Don, suggest you try the cheap things first - concentrating on rear sway bar. It is very unlikely that any aftermarket outfit will produce a sway bar narrower than the oem 17.5 mm. Consider removing the rear sway bar altogether. You'd need to have the car on jack stands with the wheels removed as most sway bars require a lateral movement for removal and wheels are in the way.
You have the V6 which is far lighter in the front than the V8 with inherently less understeer. Removing the rear bar altogether will increase your understeer, but for normal driving you will be o.k. There are plenty of vehicles out there that do not have rear sway bars. For instance my base PT Cruiser did not have a rear sway bar, but the Touring Edition does. The nice thing about rear sway bar removal is that it is easily restored. While it is out examine the bushings to determine if you have the "oval bushings."

The bounciness of the 2009 only shows itself on certain roads, and not necessarily the most bumpy roads. I did not notice the problem during my test drives of the 2009 near the dealership, but noticed it on my way home and in certain areas near where I live. The problem has moderated to some degree as the springs loosen up a bit (they were on cocaine when the car was new).

Hyundai has said that both the 2009 and 2010 will have a firm ride (some will say harsh), but that the 2010 has improved compliance in certain situations where the 2009 was too bouncy on certain roads. The 2010 suspension changes were not designed to make the Genesis into a Cadillac, so those looking for a cushy ride on the Genesis will not find one. But many people (apparently not ImInPA) have noticed a difference between the 2009 and 2010.

Some people claim that a part number change was made mid-year 2009 on certain suspension parts, so it is possible there are 3 different suspensions which could account for the fact that some don't notice a difference between 2009 and 2010.

  1. Early 2009 model year
  2. Late 2009 model year (somewhat better than the early 2009)
  3. 2010 model year
