Well, this problem was fixed once by warranty work last year but has since come back..
While using cruise control, anytime the computer senses it needs to giver more gas, a noticeable "buzz" can be heard from somewhere around the dash/wheel area.. As it needs MORE gas, the buzzing gets a lot louder.. Finally, when it needs even more gas and shifts, say going up a hill... the sound goes away as soon as it shifts. As soon as the RPM's come back down, the buzz comes back.
I think last time they fixed it, buddy mentioned that they changed a speedo cable or something, I can't remember exactly..
Anyone else have this issue?
