Dealer told me I had to pay to have tires factory aligned. They replaced the tires under the extended warranty if I would pay for the alignment as they said this was not covered. When I drove off from the service department the car was making the same roaring noise from the wheels. To this day, one year later the dealership has not fixed the car. Either the tire "expert" is not in or they just don't know what it could be. You can't even hear the radio or talk to someone in the car. It roars as long as the wheels are turning. The tire alignment light stays on even after I take it back.
