It's hard to say. I had a 2013 Dodge Avenger that had the same problem after around 40,000 miles. At first I though it was something in the suspension, but after checking everything out, couldn't find anything. Also, it was intermittent. It would do it more often when it was warm outside. I could hear it and feel it through the steering wheel. It almost never did it in cold weather. Never found anything, and it never worsened. It didn't matter if I was going straight or turning. Unfortunately, we never figured it out and I recently traded it in on my new Journey, so will never know.
