This is hard to explain so it may be tough to diagnose but I would like to get some of your opinions before it goes to the dealer. Anyway, the car is making like a knocking sound, or deep banging sound from the front end when I am cruising (not accellerating or declerating) at 35+ miles per hour. I have the 3.0 CVT so when I am cruising above 35 the RPMs go to 1150-1200. This is when the sound is loud from the front end. Anyone have any ideas. I checked under the car and there is nothing there. It is really weird but I made an appt anyway to have them look at it.
