Car has a vibration when you go over 60 miles an hour. I had the tires replaced and balanced and that did not fix the problem. I took it two Infiniti and they could not find any problems. But certainly when I'm on a smooth Road and as soon as I hit 60 miles an hour or over I can feel a slight vibration in the car. But if you're on bumpy roads you wouldn't notice the vibration. overall it's annoying it's definitely there but it's something that I can live with.
