I recently bought an altima and a few things concern me. When I turn on the car I. Hear a loud squeeking sound by the engine for about a minute then it goes away when I drive off but reappears when I turn my wheel to turn left or right then goes away while driving straight. Now the sound doesn't go away and is there when I press down on the pedal. If I'm just coasting the sound goes away but as soon as I prrss the pedal it comes back. I think it could be a few things but I'm not sure. Serpentine belt? Power steering? Any feedback would be appreciated. Also a friend looked art it when I first got it and said it wasn't the serpentine belt and that I need a motor mount replaced because the engine is knocking and has a sorta high idle.
