Honda Cars India Ltd. — Honda City - VMT - Petrol

Address:

Ahmedabad, Gujarat, 380061

I purchased Honda City VMT on 19/01/2017.
The Car is producing Rattling sound during Acceleration. I have complained to the dealer but the service person is denying and telling that there was he could not hear any such sound. I have shared audio clip for the same but no effect of that.

Since many days I am facing problem in Bluetooth connectivity and wallpaper setting, when I tried to change the wallpaper, I am not able to do it as I imported 01 image successfully by in display setting when I changed audio to wallpaper, no change is there..I tried many times but seems some software issue is there...
I want solution of above problems on urgent basis..
