I think I found what was causing the mystery rattle that I hear coming from the rear of my 1 month old car.
I tried adjusting hatch stops, applying grease between seats to prevent rubbing noise, took out rear headrests to rule that out, applied felt tape to few trims inside including license plate frame but nothing really helped. Tried tapping underneath the rear of the car on the plastic shield and it sounded just like what I hear inside the car going over rough surfaces. Closer inspection showed that it’s missing a screw. Scheduled mobile service appointment for next week for them to fix. Hopefully this is it - fingers crossed.
