I have this strange noise coming from under the hood (of course it's intermittent, so when I take it in it never happens) which normally happens after the engine is warm. I will be accelerating and it starts to make kind of a squeaky noise. Anyone else with this problem?

If the "brake" light starts showiing on my instrument panel does anyone know what that means. when I am driving sometime it will light up as I drive other times it will light up when I brake.
