Brake Abs Warning Light problems of the 2014 Dodge Avenger

My abs light and traction control light came on and once it went off the brakes stopped working then it came back on and the brakes started working again this is very scary and I feel like something wasn't done properly there is no reason for this to be happening hoping someone can figure this out soon. This all happened while driving it doesn't matter if it's on highway or dirt road.
