No Good Vibrations here

[NotMyMainAccount]

I'm so frustrated. My 2012 3.8 premium was bulletproof save all the little things that annoyed me about it, but that weren't strictly broken. My 2015 3.8 AWD Tech came right off the showroom floor with some kind of vibration issue. I hadn't test drove it because I test drove the first one they got many months ago, and then test drove one with the tech package a month later to see if I wanted it (I did but my lease wasn't up yet.)

Here's the surprising part: Today, on my fourth visit for this one issue, I drove two of the other Gennys on the lot. Both had pretty bad wheel/tire vibrations!

Which makes for a total of three out of six of theirs, if you include mine.

I'm happy to give more info about my ordeal, but what I'm really interested in is hearing about your experience. Does your 2015 have any shake that's not in the roads, either in the steering wheel or felt via our finely calibrated "butt sensors"?

Frankly I hope I hear a cascade of "nope, mine is perfectly smooth. Don't know what you're talking about bud!" I suspect that will be true for pretty much everyone but the newest buyers, within the past month or so. I'm thinking there's a possibility Hyundai received a bad batch from Hankook or their wheel supplier.

Input please! Any and all thoughts and comments welcome!

The only shaking is from the factory Haptic steering wheel.

No problem with mine.

You've been in 4 times to repair this item. Were they able to check out the wheels and tires? The only vibration I ever feel is through the steering wheel from the lane keep assist function.

I had a vibration problem with a car once. It was the tire balance but nobody could get the tires to balance perfectly. I took it to a very high end tire shop that serviced Ferrari, Mercedes, etc. They balanced it perfectly for me when nobody else, including the dealer, could. Don't know if that will help but good luck.

 

[Alwaysforward]

No issues with my 5.0 Ultimate. Is it possible they never reset the tire pressures once received from the docks? They ship them with over inflated tires.

 

[NotMyMainAccount]

Tire pressure is one of the first things to check but they're 33psi all around when cold, so no issues there. At this point to sum up, one wheel/tire has been replaced by Hyundai and all four have undergone road force balancing. This is the kind where the computer even recommends placements for all four wheels for optimum balance.

Thing is, with their help I tested my set of now-balanced tires & wheels on a floor Genny and my problem was gone. (Originally the idea was to isolate a car issue from a balancing issue by testing a perfect set from a floor model on my car, but given that every car we tried had tire/wheel balancing issues that their technician and I could easily feel, we had to switch things up a bit.)

This is definitely, positively not a haptic steering wheel issue. While that is a vibration, it is very different and doesn't vary with speed. In fact after the four wheel road force balancing my steering wheel is smooth, it's my rump that feels the telltale signs.

Problem is, this doesn't tell them what to replace. Axle issues usually show up under acceleration and that's definitely not the case. The tech said it could be any part of the drivetrain all the way up to the engine itself.

I'm just about done. The troubleshooter in me wants to keep going, but damn it all I bought a new car and want a new car, not a bag of problems. Technically I've already hit the requirements for a lemon, I just want to avoid investing the time for arbitration and all associated paperwork, etc.

LA Genesis, thank you for the input regarding getting them balanced at a high end shop. Ideally I'd get this resolved under the Hyundai umbrella as it is THEIR problem, but you're absolutely right in that I'm already down a couple grand in lost income from dealing with this so spending a bit to make the problem potentially go away is logical. My experience with my tires and wheels on another car seems to suggest it's no longer a balancing issue, but just in case I had them swap the fronts to the rears to make sure the problem stays the same. If it changes then I'll probably take your suggestion, since they've already done the best they can at the dealer.

All of these reports are very useful, keep 'em coming!

did the look at drive shafts for weights falling off? Did they look at the rotors? did they check pads? Did you move every wheel around the car . Its either bad wheel bad drive shaft or brakes. A real pain in the ass . Mac

I have a different, but similar problem with my tires.

My car has 11k on it now. When it was new, I'd get an annoying vibe from the tires when they were cold and it would disappear after a minute or two of driving. It felt like a set of old nylon tires getting a flat spot from sitting too long in one place, but it would always go away in a few miles and then everything was smooth as silk.

Now, at 11k, only one still seems to be vibrating after sitting and (I think) it's the right front, but the vibe doesn't completely go away. It's extremely subtle and I probably wouldn't even notice it if the car wasn't so smooth otherwise.

I have an appt to have Discount Tire do a balance this afternoon to find out if the remaining vibe is balance, defective tire or something else. They've always done an excellent job of balancing my truck tires so these should be easy if that's the problem. I'll keep you posted.

Funny - I had that sensation as I left work last night - almost a slight wobble/shimmy from the rear that went away after about 1 minute... weird as it happened on the newly paved access road that has felt perfectly smooth every other evening?

This am I drove the car for the first time in almost 48 hours and it was much worse than usual. It still went away (mostly) in a couple of miles, though. I wonder if there's something different about the construction of the Hankooks that causes this. I'll check with Discount Tire when I'm there this afternoon.

 

[lobsenza]

It may be flat spots from when the car sits. As the tires roll and heat up, the problem may go away. It will be interesting to note if this is primarily an 18" wheel issue or a 19" wheel issue. In addition, it may be temperature related 9worse in cold or hot climates).

That's what I assume it is, but I haven't experienced it with modern tires. I thought it wasn't a problem any more with changes in tire construction, but this isn't the first time I was wrong. Won't be the last either.

To my knowledge they have not checked the drive shafts or the rotors, and although they measured the pads as part of their regular inspection I don't this means they actually checked them for signs of unusual wear. Mechanically I'm not sure I understand why it would be brake related if it's not happening at all speeds (I don't think I mentioned speeds earlier.)

Drive shafts I definitely suspect but their tech needs to be able to feel it, and he didn't. Which was maddening for me - it's not an intermittent problem. We would be on a road that was smooth, I would go a speed that would reproduce the bump and he would agree that he felt the bumping. Then I'd go slower or faster and it was smooth, and he'd agree it was smooth. Then I'd go into the problem range again (35-65) and he'd feel the bump - then conclude it was just the road. I did this several times and every time he would agree with me and then conclude it was the road.

I get that road imperfections will change as I change speeds, but what he's suggesting is that the road itself became smooth exactly as I dropped out of the problem speeds, and then bumpy again exactly as I accelerated or braked back into them.

Now I didn't just light into him or his manager because I have to admit it took me a while to be able to feel it reliably and know it was that and not the road. It is not THUMP THUMP THUMP kinds of obvious, it's a fairly slight b-bump,b-bump instead. We also had far less than ideal testing circumstances, it's hard to find spots during the day where we could spend time going in and out of the 35-65mph range safely and on roads smooth enough to test on.

Although the test of putting my tires on the other car seemed conclusive, since their tech couldn't feel it on my car he tells me he wants to help me but his hands are tied. Normally he'd follow up on the existing ticket with Hyundai, or take action based on other similar problems that other owners have had. But either no one else has reported this kind of problem on a 2015 Genesis, or they have but only gotten as far as I have (i.e. without a solution yet.)

The reports from ckon and Nikgen regarding their vehicles also exhibiting an apparent balancing issue after sitting for a while are extremely helpful. Due to the sporadic nature of travel for me the car often sits a fair amount in between lots of use. This different vibration goes away after a mile or two, and it did even in the floor model that needed to be taken to a gas station first - was quite bad at first, but after 2mi was close to smooth. Then with my warmed up tires, was smooth. Meaning I think I'm seeing several issues:
- Balancing is probably screwed up by using cold and recently-loaded tires.
- Hankook's design causes flat-spot tires after a very short amount of time, as in a few hours to a day or two. Since it hasn't been weeks/months, they reform after getting slightly warm.
- My car might have another issue on top of all of this.

None of the 8-9 other vehicles I've owned, nor the various tires I've tried on any of those vehicles flat spot after a day or two, or even longer. I understand that at the extreme level (racing slicks) it's not advisable to let them sit long at all (http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=42), but in the context of an all weather tire on a car meant for everyday use, it seems broken.

I'm a little confused here or I missed something. Two questions: How many miles on your tires and does the vibe go away when the tires warm up? The reason I'm asking is that when my tires were new the problem was much more pronounced than it is now and even then, it would disappear when the tires warmed up. Most of the remaining symptom disappeared on it's own somewhere in the last 11k miles. Only a slight vibe remained which is why I had them balanced and rotated today.

I just returned from Discount Tire and they told me there were no tire imperfections that they could find but that the right front WAS out of balance. The trip home was very smooth, but I won't know if the "flat spot" symptom is gone until tomorrow.

So now we don't know if we both had the same problem or if there are two different things going on here. Let me know how it's going for you.

PS: It's starting to look like the Hankooks are just a finicky tire that's gonna irritate us until it's time for a tire change. I can live with it I guess, cuz they seem pretty decent otherwise.

Less than 700 miles on the tires, I've only had the car a few weeks. It's been in the shop quite a lot, as I have detected two distinct vibrations. One is the cold tire symptom and the other is something else. The latter occurs no matter how warm the car or tires are.

To me, this cold tire thing is a defect considering how quickly it occurs. These are not racing slicks or even close to them. My 2012 had about 12k miles (almost entirely city miles and no daily commute) so waiting 2-3 years for the tires to become tolerable on a brand new car is not a comforting thought. Though of course I'm glad to hear yours is working out. Appreciate the info!

Well, good luck to ya and let us know how it works out. Maybe Hyundai has to buy you a new set of tires.

Funny you post this issue. I noticed the same vibration on 3 out of the 5 different cars I test drove. When I got mine it was very slight and barely noticeable. It still seems to do it especially in the mornings after sitting all night. Then it will go away after about 5 miles or so of driving. I think it is probably the tires as others are saying. But like I said I noticed it in almost all of the ones I test drove. Some were worst than others. I test drove all three models (3.8 RWD, AWD and 5.0 RWD). So I don't think tire size matters. The AWD had some of the worst vibration. Mine is the 5.0 with 19" wheels.

 

[Brooklynk5]

might need a high speed road force balance or maybe bent rim on the inside?

 

[Onuriss]

There was a minor vibration on my 3.8 AWD model when the tires were cold. I took a look at the tire pressure and it was a little low, probably due to the change in temperatures recently. I filled the tires to the 33 psi pressure (cold) and really have not noticed it since.
