Suspension Noise problems of the 2013 Kia Motor Optima

When I first bought the car in July 2013, it was less then two weeks and I told them at century kia something was wrong with the steering. I later took it and had the alignment looked at I was told it was off just a little bit on the passenger side. About two months later it is swaying all over the road, I called century kia and spoke with their repair department and explain the problem to him and he suggested it sound like maybe a suspension problem and I told him it was an alignment issue but he told me they would need to check it out to make sure, I was going to take it somewhere else to see if it's the same thing but will allow them to look at it again. Hopefully I will get some real help because I really like my car as well.
