Suspension Issue - A new take

[Asus999]

Real funny comments.. good laugh!!!

 

[mghaynes]

Has anyone tried one of the two alternatives I've seen. Either the ARK coilovers or the HR lowering springs?

I had a VW Phaeton with the adjustable ride suspension, WOW was that wonderful. It could be made very sport suspension or all the way to floaty. The sporty was not harsh just very glued to the road. You could also change the ride height. It was even possible so the car automatically lowered at about 55 mph!

Wow it was wonderful but you got rid of it? Good Luck with your Genesis!!!

I get lots of cars and enjoy tinkering with then and improving their weakness. Currently working on the Genesis. I enjoy the challenge and the joy it gives me to make them better. I was an Automotive Engineer running the Mechanical Engineering Department of the Bendix Research Labs, so it's in my blood to improve on various cars weakness. I have strong personal drive to do such things. One of the most enjoyable things I ever did was make the most modified Nissan Murano in the country. Amongst other items was the onboard X-Box modified to run Windows. I could operate the computer via a NAV touch Screen and voice control. It had a wireless connection so that when I pulled into the garage it linked to my LAN on the home for updating and file sharing. Of course it also had internet via a cell phone communication card.

I hope to unveil my Elimination of the acceptance screen on the Genesis, on of these days. I have it working but not yet so others could acceptably do it. It is really simple in concept providing a substitute switch closing to mimic the one the DIS know puts in when you push it. It start to time out to provide the parallel wired in relay when the car is started. The problem is assembling the little circuit board with the electronic time delay, closure relay, power, interface connection and getting at the correct wiring contained in the center console.

The Phaeton was easily the most well engineered car i have ever owned. It is basically a Bentley Flying Spur. It's big flaw was the NAV system was CD based not DVD, so it was slow and had a poor interface. The Genesis is much nicer. The S Mercedes (2001) was beautify refined but had a lousy AC system. Finally the Nissan Hybrid was very very nice, had a great ride and accelerated like a banshee with a CVT for great smoothness. It was small inside and had almost no trunk space. I am enjoying every aspect of the Genesis, except the ride and that "WILL GET FIXED" along with independent switchable fog lights. So indeed I am having good luck with my Genesis.

Very commendable dedication GipperDon.. Very interesting to see your passionate interest in Automobiles and their opportunities for improvements... Hopefully you achieve your quest with the Genesis before moving onto your next project.. Would love to see you complete the project of Eliminating the acceptance screen on the Genesis, any possiblilty of a Software solution instead of hard switches?.. Good Luck..

Can't get to the hard drive! I wish someone would give me the access password and key button combination to get in. I think I could write the code. Maybe someone has a friend in the parts service department?

Possible next project a "Plug in Electic car"

"Discontent is the first necessity of progress." - Thomas A. Edison

Car ride is still harsh, Dealer still knows nothing.
Hyundai Don't fix those that don't complain just fix, mine or at the very least give out some part number so I can do it myself. This cone of silence and denial is just souring drivers that you should at least do what you are boasting you do. "CARE"

Got a direct call from a regional customer service Hyundai rep this afternoon.

1."Mike" was very nice.
2. In reply to my comment about calling Customer service about a dozen times and never getting anthing but music for an hour he said they have 60 "heads" at the call in center and that they are "Slammed"
3. He have had an email of mine forwarded to him from someplace in Hyundai.
4. He was very knowledgable of the complaints about harsh ride, both in press and on forums.
5. He knew of some ofolks traiding in to get ride of the hard ride.
6. I told hime the High end sound system was "The best" I had ever heard for clarity.
7. We discussed all the changes and tests I had made to try and smooth out the ride.
8. I told him how much I liked all the other aspects of the car and was loath to sell it off at this early time.
9. I told hime I was willing to pay for the new parts, if required and also to have them installed.
10. Had a surprising amount of background info on me.
11. At this time he did not have a single part number for the 2010 sedan.
12. We agreed to stay in touch as things develop.

At least you are on the right track Don. I mean, is'nt this the logical path for the others, before losing thousands trading, and paying more for a 2010?

Please keep us in touch on this issue. I am sure that it is possible to make the switch to most (if not all) of the new suspension parts, but I agree that they probably don't have the new parts in the US yet.

I should have added that he did seem to hear of the "Hyundai press release re. the suspension refinements" that we read from someone posting here as new news or at least I got that impression.

I also forgot that he commented that he did not know if any changes made to the 2010 would be able to fit the 2009. I discussed the lead times for: design, testing and parts suppliers and the integration into assembly lines and that changes other than springs, Damper valving, bushings were very unlikely. That changing one of the link dimension was very unlikely first because of time and second because of lack of need.

While it was a pleasant discussion it was not too proactive or technical and I felt that I will be surprised to hear again BUT GIVING CREDIT WHERE IT'S DUE HE DID CALL ME AND THAT THE ONLY CONTACT I HAVE HAD FROM HYUNDAI. so I'll keep hoping, in the mean time I take joy in that I don't have to drive my friends to dinner until the ride get fixed.

That changing one of the link dimension was very unlikely first because of time and second because of lack of need.

The changes were decided upon no later than mid-February 2009, because that is when HMA CEO John Krafcik said that he had personally tested the revision (without saying when he did it). And like the 2009 suspension, the 2010 suspension tuning for US cars was done in California. So I agree that it was not a major change.

By all previous accounts from Hyundai employees, the changes were to the spring and shock rates, and new bushings, period. My guess is that the springs were softened, but the shocks were tightened up to compensate, so the ride is still firm, but more compliant on rough spots. I suspect the new bushings are for the steering issues (tendency to pull to left).

Don, did he mention anything about whether the current dampers are adjustable for ride stiffness, or if the system is entirely contained?

 

[LLT]

Don,


Have you driven the 2010 yourself to ensure it's more to your satisfaction? Would be a shame to put all this time, energy and money and still not be happy.

Glad to hear you were able to make contact with them. I had a lot of contact with them through the Think Tank and normal channels. They just said the vehicle was "working as designed." It's a bit difficult to argue with that as it is in fact working as designed. In my case, I just didn't like the design.

 

[Bear]

Thanks Don for the time you have dedicated to this problem. I sincerely appreciate your effort.

 

[Mark_888]

Do you mean user adjustable, or technician adjustable? Have not heard anything about that from people who have bought 2010 sedans or from Hyundai employees who mentioned the specifics of the changes.

 

[GripperDon]

In my discussions with SACHS who makes the damper/shock ( I prefer the old term shock) the 2 orifices in the bi valve are not user adjustable. Actually it is a single flapper valve that controls only one orifice providing the effect of two varying levels of flow.

I have belonged to the thinktank for a long time and unfortunately have never gotten any contacts that had any value. I had actually hoped that other members would be more knowledgeable and be able to post actionable info, but no luck.

I ran into a early "Snow Bird" from back East that was kind enough to let me drive his down the street which was right outside the Shell station where we were getting gas. I thought I was going to have a stroke on the spot!!!! I really did not want to give it back.

I slid under the rear and the rear shock looked the same externally There is a stamped part number on the shock but I had on a longsleve white shirt and tie at the time and could not get to see the part number I wanted soooooo badly. He took my phone number (seemed a bit learly to leave me his, can't blame him too much other than the fact I was in Scottsdale he had no reason to trust me, I had to give hime my son's card, he is a MD to get the drive)) and he did promis to call me. IF HE DOES, I'll offer to put it on the rack on my favorite suspension alingment shop and get the so desired part number, count the coils and measure their rod thickness and look for the color code dot, In the front I thought the antisway bar might have looked thicker, which could account for the flater ride on cornering that I have read about, I could not try that as he was in a sever state on "New CAR ITIS" and it was all I cound do to get enough time for the short ride from 90th and Shea to 96th and pull into the HealthSouth lot and take a short look under the car. ( late in the day and he had no flashlight and my car was still over on the side back at the gas sation)

Hey Don, isn't there a dealership close to you where you can go ask for a test Drive of a 2010 model, and then do all your investigating. part num /coil count etc..?.. seems to me that would provide the much needed answers your looking for and maybe quicker than waiting for someone to "maybe" call you back?

 

[ajls09873]

everyone have different taste.
On the contrary, I read many moroting journalist said, Genesis suspension is too "soft".

 

[Sayantsi]

Do you mean user adjustable, or technician adjustable? Have not heard anything about that from people who have bought 2010 sedans or from Hyundai employees who mentioned the specifics of the changes.

I've always wondered if the ZF SACHS is manually adjustable or not, but I haven't followed up - either by tech or owner. Since Hyundai went with a mechanical shock that is supposed to adjust to road conditions versus an electronic shock where the driver can select things like "sport" or "comfort", the suspension may not be what the driver wants.

Don, since you are unhappy with the way your car rides and Hyundai isn't giving you answers, maybe you can get your car to Koni and they can use it for testing dampers. You'd get a free set of dampers out of it, which may help your situation.

http://www.koni-na.com/testfits.cfm

In time, quality aftermarket suppliers like Koni and Bilstein will develop dampers for purchase, but I haven't seen any aftermarket for the Genesis yet.

Just to recap Don, have you yet replaced the 09 suspension on your car with another factory set?
