2001 Oldsmobile Alero Weird ABS? Noise

First off, when I purchased this car every once in a while all the main dash lights would turn on, but if I restarted the car it went away. It happened once every few weeks, then every week, then every few days, now every time I drive it. Whenever they turn on now, it sounds like the ABS is kicking on and I feel the "vibration" in the pedal. It does it even when im accelerating now. Now sometimes all of the lights don't even come on with this happens. It will do it sometimes a few seconds apart, even in the middle of turning. Now on the left side it sounds like my strut is going out, even though I just replaced the struts about 1k ago. I got the rack and pinion done at the same time, if that matters at all.
