Im a noob to this site but im glad I found it. I recently bought my first Hyundai, a 2013 Santa Fe Sport, black in color 4 banger no turbo, navi, panoramic roof and all the other gizmos. Ive had it for about 3 months and absolutely love it!! But I do have one question, the drivers seat seems to "rock" back and forth when you shift your weight in it. Is this a common problem with these?
