Major issues with no resolution to vibration when traveling 70mph
am having an issue with my 2026 Hyundai Palisade, as soon as I drive over 70MPH I have a horrific vibration/buzzing sound in the vehicle. I brought the vehicle into the Centereach service department and they stated they could not drive the vehicle legally at 70 MPH, they sent a service mechanic with me where I drove to the express way and demonstrated the issue and as soon as I hit 70MPH the tech heard/felt the vibration in the car. This vibration is not effecting the vehicles operation, I do not feel it in the steering wheel at all. The vibration can be felt/heard between 70 and 80 MPH.
I had also researched online by simply googling " 2026 Hyundai palisade vibration over 70mph" and immediately I located a reedit post with dozens of people complaining about the same thing, and as far as I can tell from the posts, not one person was able to have it resolved (I have added links to the posts at the bottom).
The service department rotated the tires and completed a forced road balance. I did not think this was going to work, as almost every post online said they tried this and it did not fix their vehicles either. I asked them what we can do if this does not work and they stated they may need to open a ticket with Hyundai Engineering and would need the vehicle to stay with the service department until it was resolved, I told them I would need a loaner vehicle as I need a vehicle for work. The service department stated they could not provide a loaner vehicle because this was not a "verified issued" since there tech could not drive the car. This does not make any sense, I drove the vehicle with the tech, he heard the issue immediately.
I traveled the highway again today after the "forced balancing" was completed, and unfortunately it did not work, the vibration is still there and has not reduced or changed at all.
I returned again to have the vehicle checked as the sound is still present with no change. The service manager stated they tighten some screws on a panel on the bottom of the car. Again this did not fix the issue.
I truly love this vehicle and am very happy with it. I was going back and forth between trim models and choose to go for the top of the line trim, this is an expensive vehicle and is brand new, I would like to work with Hyundai to get this rectified, however I am extremely concerned by the posts I am seeing online about vehicle sitting at the dealer for 80 or 90 days while engineering works to fix the issue.
I do not feel I should have to pay for a rental car while Hyundai attempts to diagnose the issue with their engineering team.
