What could be wrong with my Buick; There is a noise coming from the engine area that gets louder when you speed up. Also my ABS light comes on, my traction control turns itself off, my cruise control turns itself off when it is in use. Also the ODO/TRIP display area is a digital read out and will sometimes turn off then back on, it will go to all green blocks then back to some strange symbles and letters.

Sounds like you have three separate problems, First, the engine noise could be valve related since it follows the engine speed, next, the ABS, cruise and traction control most likely is a wheel speed sensor they have a high failure rate and could cause the problems you describe, and lastly, the ODO and Trip read out is powered by an electronic driver inside the instrument cluster which needs to be replaced which can be performed by a clutch re-builder such as AER in Brea, California,
