It is so bad that when you drive it on the interstate the other drivers stay well away from the car. It is very hard to keep it in your own lane. It shakes to the point that sometimes it feels like a tire is about to fall off. The low tire pressure light is on but all the tires are new and are not low. By the time I drive to work, when I get there I'm so stressed out due to feeling like something bad is going to happen while driving it that I will wreck and cause myself or others major injuries. I don't know what else to do - it has been checked out too many times to count. The problem is acknowledged as being there but does not know what is causing it or how to fix it. So every time I drive it, I'm so stressed out that I'm getting stress headaches. Someone please help.
