poor parts

Good day.<br> <br> I would like to find out from renault why their duster braking pads only last on average 20 000 km. It raises the question are the duster braking pads made of inferior quality and how safe are these cars really. Twice now i had to change brake pads before 50000 km.It raises the question is Renault putting people's lives in danger by using inferior products?
