Brand new car and this problem happens since the first day i drove it. When i passed over no more than 1.5 inches speed bumps, say 20 to 30 km/h, I heard a loud knock/thump every bump. I stopped to see if any part of the car was loose but everything did look firm. Actually driving of this car is nice, good handling but the thump persists. The vehicle was left with the dealeship by days for checking but the problem was not solved; the dealership says that is nothing about suspension but they can't detect the source of the thump. The noise is more noticeable when car is cold, eg in the morning and consist of a loud thump and after a minor thump and after another lot less amplitude thump at a frecuency of about 5 to 15 Hz. This weird noise makes that the driving to be an afraid experience, since some part of the vehicle sounds like it is going to fall. I will add an audio or video in a chance.
Update from Sep 22, 2016: Here is a video with a capture of the strut tower. This is the most convenient place to take it (iphone 5s). https://www.youtube.com/watch?v=UMgHt5dcFiQ
