Thank you, everyone, for all your response. Although I am not happy, but I am somehow relieved that I am not the only with this problem and hopefully with this issue, Ford will do something about this.
My update, my delearship fixed the seal. It was really the grommet on the floor that was missing. They installed it but the carpet and insulation are still to be replaced. They said that it takes time for it to come in since they actually ordered it from their supplier. None so far and we're still waiting.
