Shimmying/Shaking Over 60 MPH

[norcimo]

I'm having the same problem , G90 2020, 10K miles. How do I approach the dealer with this?

 

[G90ATL]

2018 G90 5.0 AWD: Worked on steering wheel vibration issue for about eight months - a few weeks ago swapped out Continentals for Michelin Primacy Tour A/S tires. Also had road force balancing done according to a Genesis Technical Service Bulletin for G90s (when Michelins were mounted). Have driven car with the Michelins for several hundred miles on highway, including long trips. It is like a different car - vibration between 55-75 m.p.h. is no longer an issue. Another owner on Facebook was able to correct issue with Primacy Tour tires. Others have put new tires on car with no improvement.

After 3 yrs. of shimmy shakes, I'm now driving a G80 3.5TT Prestige. Feels like it was made by a different manufacturer from my G90! Rock solid (so far)!!

Did the dealer give you a good deal on the G90 trade?

I recently bought the Genesis GV70 2022. Right from when I started driving, it keeps shaking/ wobbly when I drive around 60 mph. And the dealers checked and said there’s nothing wrong. But I still fell it shaking around the same speed. What could be the underlying problem?

I lease a 2018 Genesis G90 5.0 HTRAC. I love the car. I leased it in July of 2018. I was childhood friends with the salesman and, because we knew each other and had previously discussed it, he knew that I absolutely cannot stand a vehicle that shakes or shimmies on the highway. Major, major issue for me. The day I took possession of the vehicle, he told me that he noticed the car shimmied/shook on the highway, even though it was brand new. It was a "demo" car, which apparently the dealership manager drove, and it had about 4,500 miles on the odometer when I leased it, but it will still deemed new. Anyway, they put a new set of tires on it at 4,500 miles just before I took possession of it.

Fast forward about eight months. It's shaking on the highway once I reach speeds of 60 m.p.h. or more, and it's driving me crazy. I take it back to the dealership, which is 2.5 hours away from where I live, and I'm told my rims are bent, presumably from hitting pot holes. I pay $250 to have a third party rim repair shop re-balance, or straighten out, my bent rims. Afterword, it drives much better. However, just a couple months later, I notice it's shaking again at highway speeds and it's driving me nuts. I take it back to the dealership (five hours of total drive time). I'm told my rear tires are below factory spec and the tread is worn down low, even though they only have 16,000 miles on them. I'm also told that the front two tires are cupped and have unevenly worn due to misalignment. I pay the dealership $607 for two new rear tires, and they cover the cost of the front two tires when I explain to them the history of the problem and the fact that they put four brand new tires on the car only one year ago. Now, it's still shaking above 60 m.p.h. It's not a jarring, crazy shaking, but it's enough to be extremely bothersome and frankly unacceptable for a $75,000 vehicle that carries a monthly payment that's about as much as my house payment.

What do I do now? Has anyone else experienced similar problems? When I had it in the shop this most recent time (earlier this month) I specifically asked if the rims were bent again and I was told no. I was also told that in order to totally fix the problem, I need four new tires. I now have four new tires and an alignment, and I still notice the shaking and it's driving my absolutely bonkers. Thoughts? Advice? Thanks in advance.

I'm currently going through this with my 2018 G90 5.0. I bought it used from the dealer with about 30,000 miles on it, and the day I drove it off the lot I felt it and called them to service it. A year later, same issue, serviced about 5 times for the same issue (4x at the purchase dealership, and 1x 2nd opinion at another dealership who suggested I take it back with their recommendation of changing the tires, stating not only did they feel the vibration, but seen the steering wheel shaking while driving). It's currently back at the dealership I bought it being serviced (for me, the last time) for the SAME vibration, they have had my car almost 2 weeks now (I guess trying to figure out the issue). The next step is filing a lemon law claim (I've already spoken with my attorney), and the dealership or Hyundai buying the vehicle back. It's truly a shame because I absolutely love the vehicle from a design aspect, and was hoping to trade it in for the 2023 in a couple of years, but I seriously doubt I'd jump back into a Genesis in the future...as I hear this vibration is an issue with 2017 through 2021 models. The Genesis service manager explained to me Hyundai knows of the issue, and it's corrected in the 2022's and 23 models coming. I guess I'll read about the 2023's and decide then.

Nothing thus far. Any advice, how do I approach this?

I believe these cars are super sensitive to any imperfections with the tire or rim!
I have a 2015 5.0, ,i had the same problems! Get your road force balancing down to atleast 8 lbs of road force.

I believe these vehicles are super sensitive to the rims and tires being bot 100% true.

I realize it's not a G90. However the suspension and weight of the car is similar. I don't drive my my 15 5.0 much. However I know these heavy cars are very sensitive to rims and tires . The tires and rims need to I be practically perfect!!
The suspension is too touchy .

I finally figured it out. I have been struggling with this for almost 2 years now with the shaking. I originally thought the silver bullet was changing out the brake fluid, but it was more than that. The car has had tires, rims, balances, alignments. I kept trying different pads and rotors, nothing worked. I tried new wheel bearings, new calipers, nothing. Then it dawned on me, one time when I was swapping out the brake pads. It was really difficult to push out the Pistons to put the brake pads back in. So I got to thinking, is it too difficult? With the brake pads out and caliper Pistons partially pushed out, I pushed one piston at a time completely in to watch for the response of the other piston. The other piston barely moved, and the Piston I pressed in almost made almost a crunching sound as I got it all the way in. So then I tried the other piston. About the same, was fairly difficult to push in and the other piston did not pop out in response. So I pump the brakes some more and retried. It was a little easier, and didn't make a that sound when I finally pushed the piston in. I also grabbed the piston and rotated it back and forth slightly. I did this over and over and over again, until I could push the Pistons in by hand almost, and both Pistons would respond to each other exactly when you would press one or the other. I did this for all four wheels, with the front having four pistons in each. Every wheel had at least one piston that was difficult to move. Problem solved immediately. No shaking no shimmying, smoothest ride it's ever been. The brakes feel amazong too. My guess is there's something with the square cut seals, not retracting the Pistons over time, and getting contaminants, creating drag from the brakes. I was more or less flushing the fluid on the walls of the pistons. I hope this helps anyone going through the same thing as me. I thought I was never ever going to figure it out. Good luck!

Can you help me understand the root cause. How exactly do the stuck brake pistons translate to the shimmy? Is it that the brakes are dragging on rotors in the spots where there are sticky pistons? Also, did you see any distortion on the pads or rotors?

Nice troubleshooting!!! Have you shared your solution with Genesis second level support? My 2019 G90 has the same issue with ‘jitters’ aover 50 mph

Good info, G90ATL, thanks. I have bought a pre-owned 2019 G90 with 13k miles and I‘m experiencing the same ‘jitter’ problem with the wheel and can feel it in the drivers seat as well. Did Genesis pay for the road force balancing (if it was under warranty)?

What ever happened with this issue? I just bought a 2019 G90 a few weeks ago and having the same ‘jittering’ issue with steering wheel….can feel it in the drivers seat as well.

I've had a similar problem with a brand-new Camry I had purchased. It took a lot of experimenting on my part to figure it out. Finally, I got it. It turned out to be "tire run-out". That is when tires are manufactured beyond tolerances, which happens to be .25" out of round...or a defective new tire. Because I was dealing with a highly regarded Toyota dealership in New Port Richey, Florida, they, Toyota dealership, paid for 95% of the bill for a new set of non-defective tires of my choice. This type of customer service is above and beyond what one would expect from a car dealership. However, they have earned lifelong customer loyalty in me. If I buy a Toyota, it will always be from that dealership in New Port Richey, Florida.

I have the same problem, same year car and same model. did you ever find out what this is?
