Maruti Suzuki — Sound creates a mirror attachment spot (Near driver seat)

Address:

Nashik, Maharashtra

Sir I have purchased Maruti Suzuki RITZ VDI on 31st Dec. 2014 from Shaan Cars, Nashik. The no. is MH-15 EP 5598. When I drive the car 200 km, it is noticed that there is sound creates at the spot of mirror attachment, which irritate me very much at the time driving. At the time of first servicing, I complained for the same, but the problem is not solved. I personally visited to showroom and service centre for the same problem, again the mechanics did some works but the problem remains as it is. So what I can do?
