I have a 2011 Sonata with 4,000 miles. Recently, I have noticed that when coming to a stop, I hear a light thump noise in the center console area near the gear shift lever. If I put my hand on the gear shifter, I can feel it move ever so slightly at the time of the noise. The noise is very repeatable. If I take my foot off the brake and start rolling and then I reapply the brake (either softly or hard) it will make the thump noise. It is not very loud and can be drowned out with loud music, but if listening to news, it is very noticeable and annoying in city traffic, where stops are very frequent. I put the car up on ramps and looked underneath and did not see anything noticeable. It will probably require the center console between the seats to be removed. Is anyone else experiencing this problem?
