2009 Hyundai Azera alignment and break line flush

Hi, I took my car in to an oil change & tire rotation. I was called and told the car needs to have the rear wheels aligned and the brake line needs to be flushed per a computer read. I'm not sure if I need to have either of these things done and was looking for advice. It seems everytime I take my car in for the oil change they find something else that needs to be done. I've heard of a front end alignment and brake line flush but not on a car with this few miles and never on the rear wheels. The cost is about $139.95 for each of these things to be done. I just don't know if they need to be done.

Thanks you for your time.
