What would cause the abs light and traction control light to come on

What is your question?

Have a 2010 dodge nitro 4x4, had front brakes installed, tires rotated and front wheel alignment done. After I had this work done my ABS light comes on, then traction control and then I loose power and have difficult time stopping because brake pedal gets stiff. Also since this was done the front end of my ride feels loose and makes me nervous driving around a curve
