Salam, basically once the ride get bumpy what you can do is get all the bushes checked if that was the issue it could be easily be resolved but worn bushes usually give sound rather making ride bumpy.
so if bumpy is the only complain then new front shocks would do the trick and give you new car feel to be honest and offer you the best of experience this car can offer.
My car is a 2011 too and has recently clocked 100k. I can only recommend periodic maintenance. Also do NOT replace power steering fluid the desi way i.e emptying it all the way and then putting in new PSF. as you remove the old one keep pouring in the new one from the reservoir bottle.
Also i would highly recommend Liqui Moly power steering fluid stop leak mentioned above in post Number 4.
which engine oil are you using at the moment, was the previous owner maintaining log of all the service done?
