What is the point of NNA? I called them today regarding my tire feathering and all they do is just listen. I recently had taken my car to get the Tire Feathing serviced and they rotated and re-aligned the tires. After I got the car back, I still noticed excessive tire noise from the tires. The dealership told me to contact NNA if this still continues and now NNA told me to take it back to the dealership???? I also have a tough time shifting from 1-2 or 2-1 in city traffic. I told my dealership and they didn't find anything they said. NNA said to take it back to the dealership. To all the people that actually have acomplished these changes, HOW do you do it???? I am going in circles here???????
