When i start driving i can hear a humming coming from it sounds like the front end, or underneath. I got new tires and that didnt change anything. The faster I go the louder it gets. I dont really have the money to take it to the dealer and they told me that it may not be covered under warranty. If they look at it and it isnt covered i have to pay for them to tell me what is wrong and that its not covered if i dont have it fixed there then its $80 an hour for the diagnostics.
