I need to replace my front brake pads, do I need to replace the rotors too? I have original stock on right now this is the first pad replacement needed.

It may be too late now but there is a service bulliten on the 03s that the dealer will replace the brake pads and calipers at no charge if you have warped rotors.

and look up TSB 05-003-04

You should feel the brake pedal pulsate if the rotors are warped.
