Audi India — Audi A4 defective steering

Address:

Lucknow, Uttar Pradesh, 226070

I had purchased an Audi A4 2013 and kept it like a child and few days back I had horrific experience that My Audi A4 steering is jammed all of a sudden with no hit signs found on the car both by my Insurance surveyor and the audi service staff, after Web browsing I came to know that there are hundreds of these complaints, and the dealer is giving Rs. 3, 00, 000 amount of bill,
So I want to know that Audi is selling defective cars as also the car is showing the word ( Defective Steering Do not Drive ).
