Vibration Questions

[pmckechnie]

Just to report, I have a 2016 Genesis 3.8 RWD base with Michelin MXM4 tires and it has NO vibrations at any speed (well up to 85mph or so), hot or cold. For the first 1000 miles or so, I would have a slight vibration when I applied the brakes sometimes but that went away completely. Now all I feel are the imperfections in the road.
On freshly paved roads the car is as quiet as a mouse and as smooth as glass.

I have a '15 AWD with Tech package. My car has Hankook tires. It does vibrate but seemingly goes away after 5 minutes or so. That's the option I voted for in the poll.

Sometimes I think it vibrates a little more/harder than others when I get in the car but that could also be me paying attention to it more some of the time, I'm not sure. I just assume the tires have flat spots but who knows.

I'm confused by the tire thing too. Like I said, I have Hankooks on mine but I thought I've read on here in multiple threads that those had been recalled? If so, I've never heard or gotten anything from Hyundai or my dealer about it.

As far as I know the letters from Hyundai and/or Hankook haven't gone out yet. I've seen two dates for the recall start date. One toward the end of January and another around mid-February.

The service adviser at my Hyundai dealer seemed to be aware of the recall and understood the difference between the new recall and the earlier, but still in effect, service campaign to replace the Hankooks.

The recall is for a certain period of manufacture (manufactured May 20, 2013, to February 14, 2015) for the Hankook Ventus S1 Noble 2. The NHTSA tire recall pages had a lot of additional information in PDF files, but when I checked yesterday the PDFs had become corrupted and could not be opened by PDF readers.

I have about 1000 miles on my 2015 Ultimate. I notice a vibration from higher speed braking. From my experience, seems like a slightly warped rotor. Will have the dealer look at my first service.

I think we should start a petition and have everyone sign it that has the vibration issue and hasn't been able to get it resolved at the dealership level. Wouldn't hurt to check out other forums too. Just an idea.

I just purchased a 2016 Genesis 3.8L RWD. I test drove a demo and the car I purchased had to be transferred to the dealership. I did not test drive it as I assume it was the same as the demo I had driven. That was a mistake. After completing the sales transaction, I drove my new Genesis home and immediately notice the vibration in the wheels. I hope that other Genesis owners in this forum that have had vibration issues can give me some insight on this.

The vibration starts around 40mph and up. When I apply the brakes to stop quickly, the vibration is much more intense. I took it back to the dealership and was told that the vibration is most likely due to the car sitting on the lot and not being moved as its supposed to me and that maybe the brake pad had formed some rust but would smooth out as I drove it. I was told to drive the car for 3-4 days and that should correct the issues and if not to bring it back. All this was told to me by the service guy.

I've driven it for 2 days and now I'm am about to drive the car back. I just feel that for $43,000 not including taxes, tags, etc. that I should not have to go through all this on a brand new car that only had 19 miles on it. This is totally unacceptable.

I read through some other posts and now I'm concerned that this is a problem with the Genesis. Other posts indicated that the vibration issues could be caused by flatspotted tires, warped rotors, tie rod issues, or out of balance wheels. Other than this, I love the car. The engine is good. its definitely something in the wheels. I don't think my boodie should be vibrating down the highway. I'm a female and not a car expert but I'm no fool and I know when something is not right.

any advice???

Another recent poster had his tires swapped for Continental DWS 06, and that solved his problem. My car had some vibration, and the dealer road force balanced it. It was mostly gone, and has improved with mileage. At about 1500 miles, it was there, but just barely.

I've got about 1800 miles now. I'll have it on the tollway later today, and see if I still have some vibration. If so, I may ask for a tire swap. The dealer said they would deal with any remaining issue at my first oil change.

Lisa,
My new 2016 Genesis 3.8 RWD also had a vibration when new only when I applied the brakes. Having been around and working on cars for over 60 years, I knew it was a brake rotor problem so I let it go. By the time it had about 1000 miles on it, it was perfect.

That was my experience, just to hopefully ease your mind about your new ride. They are great cars, smooth as glass on good roads, quiet, and a joy to drive. You will love it.

Now in your case, If you are uncomfortable with the problem, then by all means return to the dealer and explain how you feel and ask them to fix it. I am sure they will.

Well I had the same issue as Lisa and after several visits to the dealer and tire replacement the problem never went away. I even tried to replace my Genesis with another Genesis that I drove while mine was on the dealer but nobody gave me any attention. I called Hyundai and still nothing. Unfortunately I ended up losing money and time. By the end I traded for another car brand that I trust and I now don't have any problem anymore. Good luck.

I have a 2015 with 35000 km on it on my 4th set of tires still bouncing along now being totally ignored by Hyundai Canada & my dealer so l wish you well

Took the car to tire shop today. They put the wheels on a balancer and I was informed that the tires are bad and definitely the cause of the vibration. They're filing a warranty claim through Michelin for me and I'll find out tomorrow what's next. This is good, good news!!

Took the shop about 20 minutes to find the problem, compared to 2 hours at the dealership only to be told: "The vibration is normal." Add another check-mark to the ever-growing list of reasons I hate bringing my car to (any) dealership.

I'll chime in now that the book has been closed on my 3.8. I had a '13 Genesis Coupe 3.8 that had unresolved vibration issues over the course of a year of ownership. The tires, wheels and finally driveshaft were all replaced to no avail. Finally they gave me a set of Michelin Pilot Super Sports for free and said they'd done all they could. Those tires were great, but the vibration never went away completely.

Then the '15 Genesis sedan came out and I got one of the first cars the dealer received. Surely, I thought, this all new car would have worked out any issues from the old cars. It was a 3.8 RWD and I loved it right up until I felt that familiar shake. The dealer couldn't believe it, after everything the coupe had put me through, so it went back with instructions to not call me until it rode smooth. They replaced the tires, then the wheels, then the tires again and who knows what else since they went silent for a while before finally calling to report that at last the problem had been solved.

I excitedly picked up my car and held my breath as it accelerated onto the highway. By this point I was probably hyper sensitive but there it was, an ever so slight vibration in the steering wheel. It was far less pronounced but they'd still failed to solve it completely.

The car went on to have several other problems until the dealer put me into a 5.0 at a lower cost. The 5.0 is fantastic. It had the new Continental tires from the start, and while it does have some flat spotting vibration it typically goes away after a few minutes.

After living a year and a half with the first one I've come to these conclusions. There are at least three causes of vibration on the 3.8.
1) Bad wheels and/or tires. This is backed up by the fact that they replaced tires for free and many people have the initial flat spotting problem.
2) Poor quality drivetrain. This is a hunch, but I feel that there is a weak point somewhere that hard driving exacerbates. Maybe it's the driveshaft or something else but after months of spirited driving the highway vibration worsened again on my 3.8. My guess is that the cars can't hold up to aggressive driving over time.
3) Vibration at idle. I saw some mentions of this in the thread and it was also something I experienced. The V6 seems to be very rough at idle (for a luxury V6). The a/c makes it worse. Sitting at a light, uneven vibrations could be felt throughout the car, worse than anything I've ever felt in a 4cyl Sonata.

So far the 5.0 has been everything the 3.8 wasn't. Silky smooth, effortless, luxurious. Hopefully it'll hold up. I went through months of return trips to the dealer for various issues so feel free to ask about anything, maybe I've already dealt with it.

Just want to update you guys on the braking vibration issue. Went for my first service today. They cut all four brake rotors and the problem is gone. I asked about NEW rotors and the service manager said that there is a warranty claim number for it (BLAH BLAH BLAH)
Sorry I didn't get any more info. But it did resolve my problem....for now.

My 2015 5.0 vibrated when I picked it. It was manufactured in July 2014, but already had the Conti's on it when I took ownership. It seemed to me the vibrations were getting better the more I drove it, almost like a flat spot issue working itself out, but it never quite went away.

I took it in and complained and the dealer did a 4 wheel balance and all 4 were off. 3 by 1/2 oz and the front left was, according to the tech, "worse...enough to notice".

Looking at the old weight tape and the new weights he put on, I am betting that when the Conti replacements were put on they never rebalanced them.

It's much smoother now...but is it *totally* perfect? Ehhh...perhaps not, but I can live with it for sure. I will be interested to see what it feels like when I wear these tires out and put something better on. I remember my Infiniti M35 tracking like a laser when it was new, but as the tires became worn it started to shimmy a tad as well.

I have my G2 in for service for a few items now including the vibration.
The dealer concluded that the tire(s) have some belt shifts. (Michelin MXM4)

I had the issue noted right after delivery, and they balanced the tires and asked me to wait until my first oil change to further address the issue.

Last Friday, they said they were waiting to see IF Hyundai would authorize new tires.

My comment.... Whaddya mean IF???

I was pretty clear that I was not going to accept the problem as is. The Service Manager was polite in saying ... it's just the process. Hopefully that is correct.

Waiting on the Tires, and a Radio swap. I have a decent '16 Azera loaner, so I'm not too put out, I just hope this does not turn into an ordeal.

I have not taken the poll yet.. waiting for the outcome.

 

[jsmit86]

Well an update.... Michelin will authorize a replacement, but I do have to stay with Michelin.

I did a little research, and the Premier A/S seems to be a solid choice. I've asked for them. I know that they are only about $10 per tire more at retail, so hopefully I can get these for little to no $ out of pocket.

The Premiers are what I traded up to when Michelin warrantied my four defective Primacy tires. Michelin actually said I could pick ANY Michelin tire I wanted for free, but the Premiers seemed like a prudent choice. So far, a GREAT tire. A teency bit noisier that the Primacy but not horribly so.

This Premiers look like the best choice for Michelin. I need decent winter performance. The only similar tire with a slightly higher rating is the Conti Extreme Contact DWS 06. They rate pretty similar, so since it's a warranty claim, Michelin it is!

 

[tmf2004]

this is some good info... I have a lights vibration as well and my car came with Conti's, i've heard great things about the Primacy but i'll keep the Premiers in mind for next time..

After swapping my Hankooks for MXM4s I still noticed some questionable ride comfort and brake feel at the recommended tire pressure of 33 PSI. It felt like you could feel every wavy section in the road and braking was often just as oscillating.

I bumped the tire pressure up to 35-36 PSI (cold) and now the car rides and brakes like a completely different vehicle. The ride is much smoother and the brake feel is more consistent and smooth thru the length of pedal travel. This is a car that sits low to the ground and has large wheels (18/19 inch)...I don't expect it to be butter smooth. Makes me question if they got the pressure calculation wrong when developing the car.
