Hyundai Azera 2013 Automatic Gasoline I have an Azera that has a vibration, I don't know what kind of shaking it is, under my feet, whether I'm driving fast or slow. If the road is a bit uneven, I feel this shaking, it doesn't feel normal, with or without brakes. I really don't understand it. It feels like the car's screws are not tightened. With any bump, potholes, or small stones, I feel it, and there's no rattling sound or anything, it's without sound.
