Vibration at Highway Speeds

[Filbert]

So the dealer did replace one of my tires. That definitely helped, but there's still a vibration in the steering wheel and driver's seat at 60-70 mph, and you can see the console vibrating too. The service advisor told me they moved the other tires around pursuant to the road force balance procedures. So now I have to bring the car back a 4th time. Anyone else having vibration issues the the dealer is struggling to resolve?

I had the wheels balanced but not really improved.

They now want to bring me another GV60 to compare

Brought it back to the dealer for the fourth time today.

Took a ride with the shop foreman, and of course it was not vibrating much at all. The shop foreman realized that I was a car guy, and that I knew what I was talking about. So they did a road force balance one more time, and he said they found two of the tires were slightly out of balance. He also mentioned that apparently they have some kind of scoring system regarding a defective tire and that another one of the tires is marginal, but not bad enough that Michelin or Genesis (not sure) will replace it. The vibration is a slight bit better than it was this morning, but it’s definitely still there.

Not sure what I’m going to do next. I do think that the dealer has made a reasonable and honest attempt to fix the problem. I’m thinking I might take the car to a local high performance shop that has road force balancing and let them try it. Might be worth the $150 or so that I would expect it to be charged.

Tough call. Not cheap but if it works you get comfort. Perhaps they can take a good look at the tires first. If defective not much any shop can do. Tires are certainly a cheap solution. Replacing one helped so that is an indicator.

Do they have another GV60? If so, maybe test drive it. If there is no vibration swap all four wheels and see if your car stops vibrating and the other car now vibrates. If so, you will know for sure that it is at least one of your wheels and can continue swaps to find which wheel(s) it is, then get those replaced.

Delete what? Your post or the whole thread? If so - why?

I feel my gv60 vibrates a little too much than I'd like on the road however I feel the vibration more when I'm going below 40 mph than above... Not sure if it's the tires or what. Anyone have a good recommendation for better tires that won't reduce range? I have the GV60 performance edition

I have this as well and did get the tires balanced and it is slightly better but still present. Kinda frustrating.

So I took the car to a local Goodyear dealer that has a Hunter Road Force Balance machine. They charged me $88, and said the left front was 1 ounce out of balance, the right front was 1/2 ounce out, the left rear was 1 1/4 ounce out, and the right rear was 3/4 ounce out. Definitely a further improvement, but there is still a vibration most people would notice at highway speeds. Ugh!

I wonder if it's related to the tires or something else...

I should add that the last time I returned to the dealer the shop foreman told me Michelin would not replace any additional tires unless it exceeds 20 pounds or more of road force. Assume that means the one they did replace exceeded that. He told me one of the tires on my car is marginal at 18 pounds, another is 13 pounds, and the remaining two are in the single digits.

Took delivery of a new GV60 late last week and noticed right away there is a vibration at highway speeds which feels like it might be a defective tire or out of balance tire. It's certainly not severe, but it's definitely noticeable. I'm going to bring it back to the dealer who is unfortunately 1.5 hours away. Anyone else experience this, and what was the fix? TIA

I had an issue with noisy tire that sounded like belt separation on one of my Ioniq 5 tires. With all these vibration complaints I am starting to wonder about the the quality control of the Thailand made OEM Michelins.

 

[Filbert]

So I took the car back to the Goodyear dealer yesterday and told them the vibration was better but still noticeable.

Turns out they did not Road Force balance the tires. This was my fault. I knew they had a new Road Force balancing machine and incorrectly assumed that's what they would use, but turns out they just used a standard balancing machine as I did not specifically request Road Force. They charge nearly double for a Road Force balance, and for most cars a Road Force balance is considered to be overkill.

When they did the Road Force balance they discovered 3 of the 4 tires "failed". I assume the one tire that passed is the one the Genesis dealer replaced. According to the Goodyear dealer the failure threshold is 24 lbs. They knew that my next step is to return to the Genesis dealer, so they kindly provided me with a detailed receipt showing the tires on my car tested at 20, 27, 31, and 35 lbs of road force. They also texted me photos of the display on the Road Force balance machine for each tire. They did charge $160 for the Road Force balance, but were nice enough to deduct what I paid them for the original non Road Force balance last week.

Even though they don't sell Michelin tires, they said they were very surprised at the results as Michelin tires are very high quality and usually are very easy to balance. Not the first time I've heard that.

So it sounds as if Michelin may have sold a bad batch of tires to Hyundai/Genesis. Back to the Genesis dealer again!

More detail, please. What failed on the tires? What’s the relevance of The various pressures applied?

How frustrating. With what you found out it's time for Genesis to just replace the other three tires and quit wasting your time. Hopefully you will not need to escalate this to Genesis corporate to get it resolved. Will be interesting to see what they do now that you have evidence the tires are defective.

Your experience makes me wonder how well trained a typical Genesis tech is trained on using the Hunter Road Force balance machines. Or it may be a matter of experience. A tire store tech likely using the machine every day, whereas a car dealer tech is probably less of a specialist on tire issues.

Sounds as if you may not be familiar with road force balancing. The numbers OP is speaking of have nothing to do with tire pressure.

The numbers OP is quoting is how much force the tire is throwing off when spun at high speed with a force applied to the tire that mimics the weight of the car. So a road force balance machine will show how a tire performs under actual on the road conditions.

For most cars road force balancing is overkill as OP said above. But as a general statement cars with larger wheels and lower profile tires are more susceptible to vibration and sometimes need more precise balancing.

The Goodyear dealer is saying three of the tires are beyond acceptable manufacturing tolerances and can't be properly balanced even with a road force machine. If you read OP's earlier posts on this thread, you'll see the Genesis dealer told him only one of the tires exceeded the manufacturing tolerances, and they previously replaced it.

No passenger car tire come out of a tire factory perfectly balanced and perfectly round. Goodyear's threshold for a defective tire might not be exactly the same as Michelin's, and perhaps Genesis uses their own rules although I would think they follow the warranty rules of each tire supplier they use.

But what's odd here is (as the Goodyear dealer told OP) Michelin tires have a reputation for needing very little balancing correction versus other brands. Wonder if their manufacturing plant in Thailand is cutting corners. It does sound like possibly a bad batch of tires given other forum members are reporting vibration issues too, although the complaints don't seem to be widespread.

Great explanation, thank you.

I am familiar with the roadforce balancing process, and understand that the ”pounds” mentioned were not tire pressures.
What I still don’t understand is what they were. That there was a >24 pound variation/wobble from one side to another as the tire was rotated?
