Yes got some more info on it. dealership has no authority to fix anything like this.
I talked to Suzuki area manager and he was really nice and honest. He told me that it is a manufacturing fault and this can be fixed.
He said that even he is not authorized to get this fixed so he will talk to his higher ups in suzuki in karachi and he promised me that he will get the authorization to fix it.
so i am expecting to put my car in one of their shop in couple of days.
I am pretty hopeful to find the fix. No need to sale the car because of this minor thing.
