Hyundai Motor India — Steering rattling noise

Address:

Bangalore, Karnataka, 560062

I have 2011 i20 (asta). i am facing steering rattling noise on rough roads. i have given my car to the nearest hyundai (pawan hyundai kanakapura road bangalore). they changed bolt or something. but still that sound is coming while going over rough roads..

This steering problem is really annoying to me. it feels like every rough patch on the road is felt on the steering.
