I am contacting them for the issue with my 2017 G80 5.0. More in this in the advanced part of this post.
I have a 2017 G80, 5.0 Ultimate Took delivery in Sept. 2016. Other than the obvious and very annoying issue that the Ultimate DIS cannot support Android-Auto, which was not disclosed prior to purchase - in fact, they told me it could run it and send/receive texts. Now here is the real problem:
Since the redesign of the Genesis vehicle in 2015, there were many excellent improvements made to the vehicle, not the least of which was making the vehicle quieter from road noise. But it seems that whatever redesign was done to the suspension has resulted in a constant vibration through the steering
wheel and the seat that reminds me of the vibration of an ultrasonic jewelry cleaner. It is almost a slight vibration/rumble, but it's always there at any speed.
At first, Genesis replaced the tires with another set of the factory Continental Contact TX. That did not help. Then, after I contacted Continental tires, the tires were again replaced with the Continental top of the line for this size tire(s), the Extreme Contacts. Still the problem persists.
I just got the car back from Genesis/Hyundai service (for the 4th time) yesterday, February 15th, 2017. They checked everything and tightened everything in the suspension, including a small adjustement to the rear
wheel alignment. The problem persists.
It is interesting to note that none of the previous Genesis models I have owned/leased ever had any kind of vibration like this. I've owned/leased 2- 2010 4.6 Ultimate/Tech; a 2011 4.6 Ultimate/Tech; and a 2012 3.6 base model that i bought for my Mother.
With my new 2017 G80 5.0 Ultimate - After driving on the highway for 35 to 90 minutes, even on brand new asphalt, the tips of my fingers are buzzing and I feel like I have been sitting on a very fine rumbling machine.
I have read the posts about the tire flat spot vibrations that others have experienced. This is not that problem. However, my car also had that problem too. In my opinion, this vehicle is too heavy to have 40 aspect ratio tires on it, such that each morning or after the car has been sitting for at least 4 hours or more, the tires ride like they are almost square, but only for the first 10-20 miles until they heat up and the flat spots go away.
After Genesis/Hyundai replaced the tires with another stock set - Continental tires acknowledged this problem and replaced my tires with the upgraded model, the "EXTREME CONTACT", even though they thought this would make the flat spot problem even worse. I have noticed that the tires regain their round shape faster with the Extreme Contact tires. But this does not address the constant subtle vibration problem in any way.
I did remove 4 pounds of air from all four of the tires last week, and this makes the problem slightly better, but does not make it go away. Along the same line as the vibration problem, I've noticed that the entire front end suspension of the vehicle shakes, as if something were loose, when I go over a parking lot speed bump at 3+ miles per hour - but not every time. I thought this might indicate that there is a problem with the suspension dampers, which would be the same problem causing the vibration. But Genesis/Hyundai service tells me that everything is "up to spec" and that my car rides the same as several other 2017 G80s that they test drove.
Unfortunately for Genesis, this indicates that the 2015 redesign of the suspension includes either a design defect or a manufacturing defect in one of the components. Either way, Genesis cannot make this vibration go away, and they say it is normal. It was not present in any of the pre 2015 Genesis cars, and it should not be present in the post 2015 models or the 2017 Genesis brand vehicle. This is a luxury car. It should not have this vibration.
I contacted the factory rep. and they have opened a case number for my claim. If they cannot fix it, I will either file a lemon law claim on it, or they can just buy it back to avoid the bad publicity of such a claim. I have spoken to several owners of post 2015 Genesis owners that I meet in parking lots. They all have noticed the vibration and have been told it is "normal".

Unfortunately, several states have allowed manufacturers to require that you go through the BS of a BBB claim before they will review your lemon law claim. The BBB seems to always side with the manufacturer, but their decision is non-binding. So go ahead and file the BBB claim if required by your state. The you can file with the state. A pain in the arse ... but some states require this first step. Also, contact these guys:
