Vibration at Highway Speeds

[Artie Shane]

Big difference in vertical size of tire. I would expect slightly better/softer driving in normal conditions and slightly worse driving in the twisties. Has that been your experience?

Yes, but by degrees. Quieter and a smoother ride overall... more 'luxury feel' to be sure. As for twisties... since I don't really push it, I don't notice much of a difference. Mileage is slightly better as well.

Same here. My dealer told me today that it's "mostly gone" and that all GV60's have the same characteristic. He claims they drove 3 new ones and they all exhibited the same behavior. Between this and the home charging issues....sheeesh.

Replacing all 4 tires (at Michelin’s cost) cured the vibration completely.

I'm taking your advice and will be going to Discount Tire next week for a Road Force Balance. Did you contact Michelin direct or did the tire store contact them on your behalf?

I started the process by completing Michelin’s on-line feedback form. Michelin instructed me to have the tires inspected by the dealer of my choice, so went to Discount Tire.
DT handled the actual claim and reimbursement/replacement.
DT allowed me to apply the $$$$ credit towards whichever tires I wanted. I chose Hankook ION EVO AS.

Terrific, thank you for the info. Much appreciated.

Well, now that I have my GV60 back from the dealer, things are a bit worse. They balanced the tires and rotated the tires, but refused to do a road load tire balance. The SA said that they drove three new GV60's and they all had the same steering wheel vibration and that is apparently a characteristic of the car itself. BS. The steering wheel vibration is reduced, but now the entire car has a vibration above 70mph.

Don’t waste your time with the dealer - they have no incentive to help you with what is most likely a tire issue.

 

[MiniSE2GV60]

Quite true. I had it in for a recall and software update and thought (wrong) that they would be able to fix the vibration. Done.

Exactly. I first brought it to the dealer where I purchased it. Big mistake. They were clueless and inept.

 

[MiniSE2GV60]

That seems to be the overwhelming consensus, unfortunately.

I think it will be the tyres. We had a new car and on the smooth continental roads, we could feel the vibration. Back on UK's rougher roads we couldn't feel it. They were changed under warranty.

I experienced the same thing with my GV80. Fine at slower speeds, but a noticeable vibration at higher speeds. I took it to my tire shop and they did a "road force balance" (sometimes called ride matching). A bit more expensive than the standard tire balance, it made a huge difference in the ride.

[MiniSE2GV60]

Thanks, I plan on taking it to a local Discount Tire for the road force balance. Hopefully I'll get the same results as Zcd1.

Hey everyone!

I am currently getting the new Hankook iON EVO AS SUV tires at Discount tire replacing the O.E on my GV70E. I had the vibrations too in the steering wheel mostly and I am praying to god that the vibrations will be gone now..

Will post an update.

Thanks. I did think of that. But if it turns out to be something else I'm reluctant to give the dealer an opportunity to start finger pointing because someone else touched the car.

Was just curious if anyone else had seen the same issue and how it was resolved. Some cars have wheels and tires that are notoriously difficult to balance. For example I owned a Nissan Pathfinder, and there was a couple of model years where it was often impossible to get a good balance without one of the Hunter road force balancing machines and a special procedure outlined in a TSB Nissan published.

And one other thing I thought of. When I took delivery on the car on Thursday I had to wait an extra 2 hours after signing all the paperwork because they said they were having trouble prepping the car. The way they described it was that there was a bunch of steps they needed to go through to complete the procedure, and some issue with the TPMS was preventing them from proceeding. I don't know any more details, and it sounded like a software issue, so I'm guessing maybe what they were doing was taking the car out of "shipping mode" as I know Porsche dealers need to do before delivery. Or perhaps they had to replace one or more of the TPMS sensors and did not correctly balance the tire after re-mounting.

Check tire pressures and get a shop that does road force balancing..They will check rims for straightness, etc while they do the balance..

I'm posting this in multiple threads for visibility since it seemed like a non trivial amount of GV60 owners had vibration at higher speeds.

For others out there going through this issue, I want to add my abridged story:

My local dealer (Genesis of Madison, really just a Hyundai dealership) was a nightmare to work with, and actually stripped a lug bolt socket while, "fixing," my issue which they ultimately declined to do fully despite 2 independent mechanics agreeing on the issue. Weirdly, they replaced the 1 rear drive shaft under warranty that wasn't in as bad of shape as the other, and rebalanced my wheels. They charged me ~$340 for the rebalance but obviously the issue wasn't gone because the other drive shaft needed replacing, and now I needed a wheel hub repaired that they said they, "couldn't have damaged." You were the only morons that worked on the car... you did it, a$$holes. Also, I'm going on a limb that rebalancing wheels after this kind of maintenance should/would be related to the warrantied part and therefor covered.
The issue for me, as noted, was 2 defective rear drive shafts. The boots that go over a joint on the drive shafts simply fell apart/slipped off through no fault of my own, all the grease inside was slung out, and the bearings simply did not do their job at this point. There was no damage to anything else on the way to these boots so it wasn't like I ran something over and perished BOTH boots, and nothing else around them. It was simply insane to suggest otherwise. Enter the vibration at higher speeds (for me, 65-75+) virtually all of the time. Before the diagnosis and ACTUAL repair of the drive shafts, I tried 3 sets of wheels with 3 sets of tires (including all OEM). Tires/wheels were all fine, obviously, as it was the drive shafts.

I worked with Genesis corporate to then take my vehicle to Genesis of Appleton who were a DREAM to work with. They had my car for 2 months but I had a loaner the entire time, and they actually fixed everything. It sounded like Genesis corporate would be going after Genesis of Madison for at least some of the repair costs, but $3500 later in parts/labor, my GV60 Performance was fixed and I owed none of that.

Good luck to all but it may be worth $50-150 to have an independent mechanic check your rear drive shafts (maybe front as well), and take that to your Genesis dealer if they don't believe you/won't work with you to replace this obviously defective part on some GV60s.

Thanks for digging up this thread that I had never stumbled upon. I am chasing a similar vibration that has been present since I took delivery a year ago. I struggled with my original dealer, an NTB location, a Mr tire location and now a 2nd dealer. I have have now had all 4 tires replaced but with the same Michelin OEM tires. My car was an early 2024 (built in June 2023) that I bought in October 2024. The 2nd dealer (and Michelin) insisted that the damage to the tires was caused by negligence on the part of the first dealer. I have only driven it a couple weeks since the 2nd pair of tires were replaced. But, I definitely don't feel like the vibration has been resolved.

The best part is, during this adventure, all 4 wheels were damaged (cosmetic), completely restored by an amazing wheel shop, and then damaged again last month by the 2nd dealer. I am picking the car up again tomorrow with the 2 damaged wheels repaired again. When I pick it up, assuming I am pleased with the repair, I am contemplating having a discussion with the service manager. I wish this thread was more conclusive. It seems that some have seen improvement with new Michelins, others from another tire brand, and others with axle replacement. My car is a bit newer than the recall. I am not quite sure what approach to take.

Sorry to hear about all the BS you've had to go through, and you don't even have it fixed yet.

I'd recommend getting a flashlight and looking and feeling inside/under the suspension area and also behind the wheel to see if there's any grease slung about as basically every component on one side had some grease for my GV60, and the other side had a good amount as well. Would be a great/easy starting point and something you can tell the dealer to get them to look into those drive shafts possibly.

The drive shaft boots, as my main independent mechanic tells me, are not something that can be replaced and refilled with grease as the bearings running without proper lubrication basically compromises them.

Good luck. Hope you get things solved as it's a great car when it works and we get to drive it.

Did you also have a sort of humping vibration around 35 mph as well as vibration at speeds above 65? I had each of those but the dealer was blaming it on bad tires and told me I'd have to take it up with Michelin. My tire store was certain the 35 mph humping was because of loose foam in one of the tires but checked them and found no loose foam. I ended up buying new 19-in wheels and tires but still have the same vibrations - although not as bad.

I was assuming that I might have a bent driveshaft but will be checking the boots tomorrow.

I did not have anything discernable around 35mph. Mine is almost exclusively around 70-75 and with the cold weather, I've actually noticed it come back some. Not as bad though it does seem to simply be certain roads. Going to test/keep note some more. but truly just wondering how much of the car is just insanely sensitive to bad drive shafts/roads/wheels/tires.
