BMW India — bmw car 5 series

Address:

New Delhi, Delhi, 110048

I own a bmw 5 series car, which i purchased last year from a friend. It is otherwise manufactured in 2011.
I have seen a peculiar problem. The rubber in the door handles (Inner side of the door) has decayed or melted with the result that it sticks to the hand and dirties the hand each time a door is handled.
I have been driving cars of various brands over last more than thirty years and have never been confronted with such a problem. The obvious reason seems to be the poor quality of rubber used on the inner side of the door handle.
I assume and expect that bmw must have received similar complaints regarding similar cars/models of around the same time.

Pl. Let me know how bmw is willing to help the situation as a responsible car manufacturer. Needless to mention that a deficiency like this is not expected even in much lower brands.

I await a response
