I visited my third dealer and today I drove a used 2021 EX with 23000 miles and Pirelli tires, not Michelins, there was no vibration. Calling my advanced rep right now and will report back.So my Kia dealer called me back and said a tire was not balanced and maybe their machine did not do it right and it was ready BUT they can not drive it above posted speed limit which is 60 but it drove great at 60. I am pasted pissed off. I told them I will be there at 4 and need someone to drive with me at 70 to make sure it is fixed. I will let you know how that goes
