XPS 15 9570 making weird sounds from inside

I bought the XPS 9570 in the month of may, it posed a great number of problems in the start like temperature and performance issues, I discussed that in other thread but dell was good enough to reply and fix the issues with consistent bios updates. It has been only 4 months now and new problems have started to occur. Whenever I lift my laptop I hear some sought of a sound from inside the laptop as if something is displaced and moving around. moreover, my keyboard is also a little weird like my space bar keys is depressed from one side and raised on the other similar thing with the left Ctrl key first, I thought it may be normal but when I searched I couldn't find any similar problems on the net. But now something new has come to my notice today I was just randomly playing with my laptop and I heard the great rattling sound from the inside of the keyboard as if something was broke so shaked it to confirm and it made that rattling noise twice and then stopped and I haven't heard it since then and also there was time while closing the lid there was strong thud in inside the laptop. This laptop is giving me tension every day. the trackpad in its cutout in the chassis is displaced to right a little bit. same case with the fingerprint sensor it doesn't align up with the cut out in the chassis. I know that these details are too minute to discussed but it feels bad when spending 1600 dollars on a laptop with such unfinished machinery.
