Sounds like rubber bushing or ball joint, not shocks. You can go under the car and spray the bushings one by one with WD40 and see when/if the sound will go away. My bet is on the sway bar connecting rod or the lower control arm bushing or BJ.
Many guys here will tell you that it is not advisable to visit official dealer with this car. Just a waste of time and money, with a very rare exceptions. As most of us have figured out the dealers are not in the business of fixing cars, they are in the business of making money
