Vibration Questions

[ksoze]

I could be wrong about any of this and I'll be glad when the cause(s) is finally discovered cuz I'd sure like my car FIXED!

I'm rooting for you....

My car is primarily used for trips and can stay in garage for several days...I never felt vibrations from the Hankook tires. Sweet mysteries of life why some cars have the problem and majority of owner do not.

Hi, xsolara, would you answer a couple of questions to satisfy my curiosity?

First, do you have AWD, and second, what are your exact driving conditions for the first two miles, or so, when you leave your home?

I have a theory that the problem simply goes undiscovered sometimes and you may be able to help me fill in the blanks. TIA.

#1 Yes AWD
#2 First .3 of a mile speed is 35mph after that it's 55mph
#3 7-8 AM


Hope that helps......share your theory

Thanx - I worded the question wrong. What are the road and speed conditions as you drive those first couple of miles?

My theory is that if the first roads you encounter as you leave home are not smooth, vibration could occur, but might never be noticed. Also if your speeds have to stay down for a couple of miles it could also hide the symptom. I'm not saying it happens much, just wondering if it happens at all and would be having an effect on some of the numbers. Thanx again.

Road are in good condition and I'm sort of a nut as far as how my car drives and believe me I would be knocking on the front door of the dealer if I had a problem
I am completely happy with the performance and driving dynamics ...........
When buying an electro-mechanical device like a car ---sometime something could go wrong and unfortunately you got that one

Yeah - and my problem is that I love it! It's otherwise perfect (except for the sunroof rattle) - there's not another car out there that I would prefer! I sure hope I can get this one fixed.

PS: Glad yours is trouble free.

True, however flat spotting is a tire issue not a car issue. It is inherent in low profile performance tires which seemed to take some Genesis buyers by surprise, hence the switch to a new tire.

I don't know; I just can't buy this. I've had four vehicles in the last eleven years that all have been equipped with low profile, high performance, summer tires. These cars, each with multiple sets of tires, have never exhibited flat spotting.

Hi Kzose. Although I don't agree with your opinion, I can understand it and respect it. From what I gather from the Tire Rack article, this is the essence of flat spotting concerning performance tires:

The tread compounds and firm, nylon reinforced internal constructions used on high performance and high speed-rated tires are more susceptible to flatspotting.

I don't think that "more susceptible to" is the same as "many of these tires have a problem with flat spotting."

Over the past more than ten years I've spent a lot of time on forums for BMW, the second generation Cadillac CTS, and Ford Mustang. I can't remember any time where flat spotting has been brought up as a major issue on those forums the way it has been here.

Anyway, for me, the issue with the vibration that I'm concerned with is probably not flat spotting. Two test drives in two different Genesis's, at two different dealers, had vibration problems that did not go away on extended drives. I think the problem I've experienced has to do with the wheels, drive train, or possibly the suspension.

fwiw...the new michelin mxm4s on my genesis also exhibit flat spotting after sitting overnight. how do i know this...last night I stayed at a hotel situated right next to a highway. this morning i promptly got on the highway and sped up to 65 mph. yep, there was obvious flat spotting for the first few miles. not completely surprised given the fact the michelins on my regal did the same thing...albeit usually only at colder temperatures.

Someone earlier in the thread brought up whether it could be the rims and not tires/suspension/chassis for some of the vibration issues. I believe they swapped rims and tires from another Genesis and the problem went away. Has anyone else done this instead of just changing tires on the same rims?

I have been waiting for the 2016's to arrive before purchasing and this thread ... worries me to say the least.

I replaced my original rims, but kept the Michelins - no joy.

i'd be shocked if it's the wheels causing the flat spotting. it's not like the metal in the wheels would develop a flat spot, and then after several miles come out of it!

I'm not proposing that rims are causing the flat spotting problems but questioning whether they are causing some of the vibration issues some owners have on the highway. There was at least one person that stated they had damaged/defective rims where the abnormality was not obvious like a bent rim from a curbing incident.

ckon, do you have the type of vibration that goes away after a short period of time (typical flat spotting) or the persistent vibration at certain speeds?

I have BOTH, but the high speed vibration is intermittent, not constant, usually most noticeable above 65 mph.

I have replaced my rims and even though the original rims were bent to various degrees, the distortion wasn't causing the majority of the vibration. Both of the vibrations remain in spite of the replacements.

The temporary vibe is annoying, but at least it goes away. The high speed vibe ruins the pleasure of driving such a fine car on the highway.

 

[dirtyoldman]

Is the high-speed vibration always at certain speeds so if you alter your speed a few mph it will go away? The fact that you state it is intermittent worries me as a test drive may not be enough time for the problem to manifest in a specific car (assuming all cars are not affected based on the poll).

Last clarification is what actually vibrates during high-speed driving? The steering wheel? Driver's seat? Entire car? My wife would probably say it is just in my mind, but I'm extremely sensitive to annoying NVH issues. "I don't hear a thing" is usually the response to me complaining about a rattle.

Your assumptions are correct: I may not experience the vibration at any given time even within the speed range where it can and does occur. That's one of the things about this issue that's driving me crazy. Or crazie-er.

I can feel it in many places - the dead pedal, the steering wheel, the console. One reliable place to make sure I'm feeling the vibration, not changing road conditions, is when I place my hand on the horn pad. I can actually watch the skin on my hand quiver in sync with the vibration. My wife can feel it, but admittedly, it doesn't bother her as much as it does me. She's much more pissed about the sunroof rattle.

I just had enough of it and being on service and complaining about it.

I bought a 2015 Genesis 3.8 after thinking for a long time. I never had a Hyundai before and honestly did not trust it as a reliable car. Initially the car performed well in all aspects but at 1k miles the car started to vibrate and few more miles the steering wheel also started to vibrate really bad.

- First Service
The vibration just got worst and at the first service and some internet research I was asked to replace the tires due a Hyundai recall, which I did. Well, that did not fix the vibration issue but just made worst. I also opened a complain with Hyundai about the vibration.
- Second visit
I went back to the dealer and explained in details what was happening. They inspect and said that had to perform a tire balance as they were off.
- Third visit
Vibration was still as before, specially around 50-60 miles. So, took it back to the dealer and again inspection and more adjusts and nothing.
- Fourth visit
At this point I was upset and did not want the car anymore. Went back to the dealer and asked them to trade in for another car, even talked to the owner. He asked the service manager to ride my car which he did and even with the vibration he said it was normal. I told him that the loaner Genesis they gave me to drive while my car was in service did not have it and he should drive the loaner to compare it. He said the owner would take care of my issue. After almost 3 hrs seated at the dealer waiting for someone to talk to me I went to search for the owner again and ask what would happen. At that point the owner was busy and nobody could help me. So, I decided Hyundai never more and left to trade it for another trusted and reliable brand.

Make sure you have complete, descriptive service records. They will make or break a lemon case. Good luck and don't give up.
