I own a new ford figo purchased @jan 2016 which is just 9000kms done. (majgxxmtkgfm34305)
I'm very much happy with the car unlike others who seems to be very dissatisfied for buying ford. it's just i'm not happy with the plastic quality used for the doors. the problem i'm facing is,

Whenerver i release the clutch i notice a noise coming from both left and right front doors. it seems to be coming from the seat belt panel and just below the door lever. few days ago i reported to ford authorized service center at mody ford, nagole, hyderabad.
They seem to have fixed it but soon after 3 days the noise again came back and it kept on increasing day by day. now when i checked it yesterday, the door was making noise even if i touch it, it feels like hollow and empty and i'm very shocked by this. the plastic used there seems to be very cheap.

And i've enquired my friends about this who own the same car, and even they are facing the same problem.
I request mody ford nagole hyd to fix this asap and i need a permanent fix unlike earlier which was just a temporary fix.
The vehicle is only 9000kms done, just imagine about the long run say after 1 lakh kms???
