The car was having a wa, wa, wa, wa, wa, wa, wa, noise from the front end when I drove on the interstate. After taking my car to get the tires and wheels balanced and rotated the problem remained. Next, I went to the dealership where the vehicle was purchased. They informed me the problem was the "front wheel hub". It was not covered in my warranty, but they said it would be repaired at no charge. Problem solved.
